Problems to be Solved by the Invention

[0004] Among smoke sensors, there are smoke sensors having a storage function. However, when a test is performed to output to external equipment according to the test result of the operation related to fire of the smoke sensor, when a storage operation for a predetermined time is performed in the smoke sensor, the time required for this test becomes long.

[0005] One of the objects of the present invention is to shorten the time required for a test to output to external equipment according to the test result of the operation related to fire of a smoke sensor having a storage function.

Means for Solving the Problems

[0006] One aspect of the present invention provides a smoke monitoring system comprising a smoke alarm panel connected to an external device and a smoke sensor connected to the smoke alarm panel, wherein the smoke sensor has an acquisition unit that acquires an instruction to perform an external output test which involves outputting to the external device, a test unit that performs a fire-related operation test in accordance with the execution instruction without performing a predetermined time accumulation operation which is performed in a fire test which does not involve outputting to the external device, and a transmission unit that transmits the results of the test to the smoke alarm panel, and the smoke alarm panel has a receiving unit that receives the results of the test from the smoke sensor and an output unit that outputs a signal to the external device according to the results of the test. [Effects of the Invention]

[Figure 12] This figure shows an example of the configuration of an independent smoke sensor. [Modes for carrying out the invention]

[0009] composition Figure 1 shows an example of the configuration of a smoke monitoring system 10 according to an embodiment. The smoke monitoring system 10 is installed in fire-protected buildings such as server rooms, data centers, and clean rooms. The smoke monitoring system 10 detects signs of fire by monitoring the state of the ambient air in the fire-protected building. By detecting signs of fire in this way, it becomes possible to respond quickly in the initial stages.

[0010] The smoke monitoring system 10 comprises a monitoring device 100, a smoke alarm panel 200, and a plurality of dependent smoke sensors 300. The monitoring device 100 and the smoke alarm panel 200 are connected via a first signal line 11, such as a LAN (Local Area Network). The plurality of dependent smoke sensors 300 are connected to the smoke alarm panel 200 via a second signal line 12. In addition, external equipment 500 is connected to the smoke alarm panel 200 via a third signal line 13. Although only one smoke alarm panel 200 is shown in Figure 1, multiple smoke alarm panels 200 may be provided.

[0011] In the smoke monitoring system 10, fire tests and external output tests are performed at predetermined times, such as during installation and maintenance. The fire test is a test to confirm that the dependent smoke sensor 300 is functioning correctly. No output is made to the external equipment 500 during the fire test. The external output test, also called a counter test, is a test to confirm that the dependent smoke sensor 300's operation to transmit an alarm to the external equipment 500 in response to a fire detection is performed correctly. This transmission refers to the transmission of an alarm. Output is made to the external equipment 500 during the external output test. During the external output test, it is necessary for a person to be present at the external equipment 500 to confirm whether the alarm has been transmitted to the external equipment 500. Therefore, it is preferable that the time required for the external output test be as short as possible.

[0012] The monitoring device 100 is used to monitor the smoke alarm panel 200 and the subordinate smoke sensor 300 together. Further, the monitoring device 100 gives an execution instruction for an external output test to the smoke alarm panel 200 and the subordinate smoke sensor 300.

[0013] The smoke alarm panel 200 is a device that receives the smoke detection result from the subordinate smoke sensor 300 and outputs an alarm according to this smoke detection result. The output of this alarm includes a transfer report to the external equipment 500.

[0014] The subordinate smoke sensor 300, also called a communication - type smoke sensor, is a smoke sensor subordinate to the smoke alarm panel 200. Here, "subordinate" means that the smoke alarm panel 200 is responsible for part of the smoke alarm function. The subordinate smoke sensor 300 detects the surrounding smoke and transmits the smoke detection result to the smoke alarm panel 200. Also, the subordinate smoke sensor 300 executes a test according to the instruction of the monitoring device 100.

[0015] The external equipment 500 is external equipment to which a transfer report is made from the smoke alarm panel 200 in response to the occurrence of an alarm. The external equipment 500 includes equipment such as, for example, warning lights, fire - fighting equipment, disaster prevention control panels, broadcast equipment, and equipment of security companies.

[0016] FIG. 2 is a diagram showing an example of the configuration of the monitoring device 100. For the monitoring device 100, for example, a general - purpose computer is used. The monitoring device 100 includes a control unit 101, a storage unit 102, a communication unit 103, an operation unit 104, and a display unit 105. Each part of the monitoring device 100 is connected via a bus.

[0017] The control unit 101 is a processor that controls each part of the device and performs various processing. The control unit 101 includes, for example, a CPU (Central Processing Unit). The storage unit 102 is a memory that stores programs and various data for realizing the functions of the device. The storage unit 102 includes, for example, at least one of ROM (Read Only Memory), EPROM (Erasable Programmable ROM), EEPROM (Electrically Erasable Programmable ROM), and RAM (Random Access Memory). The communication unit 103 is a communication interface for connecting the device to the first signal line 11. The communication unit 103 is used to communicate with other devices connected via the first signal line 11. The operation unit 104 is used to operate the device. The operation unit 104 includes, for example, a mouse and a keyboard. The display unit 105 displays various information. The display unit 105 includes, for example, a liquid crystal display.

[0018] The control unit 101 functions as a transmitting unit 111, a receiving unit 112, and a display control unit 113. These functions are realized when the control unit 101 executes a program stored in the storage unit 102, performs calculations, or controls each part of the monitoring device 100.

[0019] The transmitter 111 transmits instructions to the smoke alarm panel 200 to perform external output tests at each of the multiple alarm levels, in response to an operation that instructs the system to perform external output tests at each of the multiple alarm levels. Each of the multiple alarm levels indicates that the smoke concentration is above a different threshold. In one example, the multiple alarm levels are three levels: "Alarm 1" to "Alarm 3". "Alarm 1" is the lowest alarm level. "Alarm 2" is the second lowest alarm level. "Alarm 3" is the highest alarm level.

[0020] When a test is performed by the dependent smoke sensor 300 in accordance with the execution instructions transmitted from the transmitting unit 111, the receiving unit 112 receives the results of this test from the dependent smoke sensor 300 via the smoke alarm panel 200.

[0021] The display control unit 113 displays the test results received by the receiving unit 112 on the display unit 105.

[0022] Figure 3 shows an example of the configuration of the smoke alarm panel 200. The smoke alarm panel 200 comprises a control unit 201, a storage unit 202, a first communication unit 203, a second communication unit 204, an operation unit 205, a display unit 206, and a transmission circuit 207. The various parts of the smoke alarm panel 200 are connected via a bus.

[0023] The control unit 201, memory unit 202, first communication unit 203, operation unit 205, and display unit 206 are basically the same as the control unit 101, memory unit 102, communication unit 103, operation unit 104, and display unit 105 of the monitoring device 100, respectively. However, the memory unit 202 stores a transmission database 221 in addition to the program for realizing the functions of the smoke alarm panel 200. The operation unit 205 includes, for example, operation buttons. The display unit 206 includes, for example, a 7-segment display and an LED (Light Emitting Diode). The second communication unit 204 is a communication interface for connecting the device to the second signal line 12. The second communication unit 204 is used to communicate with other devices connected via the second signal line 12.

[0024] The alarm transmission circuit 207 transmits an alarm to the external equipment 500 when an alarm occurs. The alarm transmission circuit 207 is an example of the "output unit" according to the present invention. The alarm transmission circuit 207 includes a plurality of relays. Each relay includes a coil and a contact. In one example, the alarm transmission circuit 207 includes a first relay to a third relay. The first relay to the third relay each include a first coil and a first contact, a second coil and a second contact, and a third coil and a third contact, respectively.

[0025] The contacts included in the alarm transfer circuit 207 are connected to the external equipment 500 via the third signal line 13. Each contact is pre-assigned a signal or alarm level that triggers an alarm transfer. Each contact includes a first terminal and a second terminal. Under normal circumstances, no current flows through the coil, so the first terminal is closed and the second terminal is open. However, when the alarm transfer trigger assigned to the contact occurs and current flows through the corresponding coil, the first terminal opens and the second terminal closes. When the second terminal closes, both ends of the second terminal become conductive, and a contact signal is output to the external equipment 500 connected to the second terminal.

[0026] The control unit 201 functions as a transfer unit 211, a receiving unit 212, a display control unit 213, and a transmission control unit 214. These functions are realized when the control unit 201 executes a program stored in the storage unit 202, performs calculations, or controls each part of the smoke alarm panel 200.

[0027] The transfer unit 211 transfers the execution instruction for the external output test transmitted from the monitoring device 100 to the dependent smoke sensor 300. The transfer unit 211 also transfers the test results transmitted from the dependent smoke sensor 300 to the monitoring device 100.

[0028] When a test is performed by the dependent smoke sensor 300, the receiving unit 212 receives the results of this test from the dependent smoke sensor 300.

[0029] The display control unit 213 displays the test results received by the receiving unit 212 on the display unit 206.

[0030] The alarm transmission control unit 214 outputs a contact signal to the external equipment 500 by switching the connection state of the contacts of the alarm transmission circuit 207 according to the test results received by the receiving unit 212.

[0031] Figure 4 shows an example of the alarm transfer database 221. The alarm transfer database 221 shows the correspondence between contacts and the alarm transfer triggers assigned to those contacts. The alarm transfer database 221 includes contact identifiers and alarm transfer triggers. The contact identifier is information that uniquely identifies a contact. The alarm transfer triggers include alarm levels or signals. Each contact identifier is associated with an alarm transfer trigger assigned to the contact identified by that contact identifier.

[0032] Here, it is assumed that the first to third contacts included in the alarm transmission circuit 207 are each assigned alarm levels "Alarm 1" to "Alarm 3". In this case, as shown in Figure 4, the identifier of the first contact is associated with and stored the alarm level "Alarm 1". Similarly, the identifier of the second contact is associated with and stored the alarm level "Alarm 2". Furthermore, the identifier of the third contact is associated with and stored the alarm level "Alarm 3".

[0033] Figure 5 shows an example of the configuration of a dependent smoke sensor 300. The dependent smoke sensor 300 comprises a control unit 301, a storage unit 302, a communication unit 303, and a smoke detection unit 304. Each part of the dependent smoke sensor 300 is connected via a bus.

[0034] The control unit 301, the storage unit 302, and the communication unit 303 are basically the same as the control unit 101 and storage unit 102 of the monitoring device 100, and the second communication unit 204 of the smoke alarm panel 200, respectively. However, the storage unit 302 stores a preset storage time in addition to the program for realizing the functions of the dependent smoke sensor 300. This storage time is an example of the "predetermined time" according to the present invention.

[0035] The smoke detection unit 304 draws in ambient air and measures the smoke concentration. This allows the smoke detection unit 304 to detect smoke present in the ambient air. The range of smoke concentration that the smoke detection unit 304 can measure is, for example, from 0.0001% / m³ to 20.0% / m³. For smoke detection, methods such as total scattered light detection or dual light detection are used. However, the method of detecting smoke is not limited to these methods and other methods may be used. The smoke concentration measured by the smoke detection unit 304 is stored in the storage unit 302.

[0036] The control unit 301 functions as an acquisition unit 311, a testing unit 312, a determination unit 313, and a transmission unit 314. These functions are realized when the control unit 301 executes a program stored in the storage unit 302, performs calculations, or controls each part of the dependent smoke sensor 300.

[0037] When the acquisition unit 311 receives an instruction from the monitoring device 100 to perform an external output test at each of the multiple alarm levels, it acquires this instruction via the smoke alarm panel 200.

[0038] The test unit 312, in accordance with the execution instructions acquired by the acquisition unit 311, performs fire-related operations at each of the multiple alarm levels without performing the predetermined accumulation operation that occurs in fire tests without output to the external equipment 500. These fire-related operations include operations performed when a fire occurs and operations performed when signs of a fire occur. The test unit 312 may also perform fire tests in addition to external output tests. In this case, the test unit 312 does not perform the accumulation operation during external output tests, but performs the accumulation operation during fire tests.

[0039] The dependent smoke sensor 300 has different thresholds pre-set for each of the multiple alarm levels. For example, the thresholds for alarm levels "Alarm 1" to "Alarm 3" are set to increase in the order of "Alarm 1", "Alarm 2", and "Alarm 3" within the range of 0.01% / m to 20.0% / m. The thresholds set in this way are stored in the memory unit 302. The test unit 312 performs a test of the operation related to fire at the target alarm level by simulating raising the smoke concentration to the target alarm level threshold. In addition, the test unit 312 controls the determination unit 313 so that it does not perform storage operation during external output tests.

[0040] The determination unit 313 determines the appropriate alarm level by comparing the smoke concentration stored in the memory unit 302 with the threshold values ​​for alarm levels "Alarm 1" to "Alarm 3". For example, if the smoke concentration is less than the threshold value for alarm level "Alarm 1", the determination unit 313 determines that it does not fall under any of the alarm levels "Alarm 1" to "Alarm 3". If the smoke concentration is equal to or greater than the threshold value for alarm level "Alarm 1", the determination unit 313 determines that it falls under the alarm level "Alarm 1". If the smoke concentration is equal to or greater than the threshold value for alarm level "Alarm 2", the determination unit 313 determines that it falls under the alarm level "Alarm 2". If the smoke concentration is equal to or greater than the threshold value for alarm level "Alarm 3", the determination unit 313 determines that it falls under the alarm level "Alarm 3".

[0041] In this case, in a fire test that does not involve output to the external equipment 500, the determination unit 313 performs an accumulation operation for the accumulation time stored in the memory unit 302 before determining the alarm level. For example, if the accumulation time is 20 seconds, the accumulation operation is performed for 20 seconds from the time when the smoke concentration stored in the memory unit 302 first exceeds the threshold of the target alarm level. If, after the accumulation time has elapsed, the smoke concentration stored in the memory unit 302 is above the threshold of the target alarm level, the determination unit 313 determines that the target alarm level has been reached. On the other hand, in an external output test that involves output to the external equipment 500, the determination unit 313 determines the alarm level without performing this accumulation operation, under the control of the test unit 312.

[0042] The transmitting unit 314 transmits the results of the test performed by the testing unit 312 to the smoke alarm panel 200. The test results show the smoke concentration stored in the storage unit 302 and the corresponding alarm level determined by the determination unit 313.

[0043] operation Figure 6 is a sequence chart showing an example of the operation of an external output test. This operation is initiated when an external test is performed.

[0044] In step S11, the worker uses the control unit 104 of the monitoring device 100 to select the dependent smoke sensor 300 that is the subject of the external output test and performs an operation to instruct the execution of the external output test.

[0045] Figure 7 shows an example of a monitoring screen 150 displayed on the display unit 105 of the monitoring device 100. The monitoring screen 150 is displayed on the display unit 105, for example, in response to an operation by a worker. As shown in Figure 7, the monitoring screen 150 has an operation area 150a, a selection area 150b, and a display area 150c. The operation area 150a includes a "Test" button 151. The "Test" button 151 accepts an operation to specify the target alarm level from "Alarm 1" to "Alarm 3" and to instruct the execution of an external output test. This operation is performed by the operation unit 104.

[0046] Here, it is assumed that the multiple dependent smoke sensors 300 include a dependent smoke sensor 300A. For example, when performing an external output test at alarm level "Alarm 1" for the first time on a dependent smoke sensor 300A, the worker uses the "Test" button 151 on the monitoring screen 150 shown in Figure 7 to select the dependent smoke sensor 300A and instructs it to perform an external output test at alarm level "Alarm 1".

[0047] Figure 8 shows an example of a confirmation screen 165 displayed on the display unit 105 of the monitoring device 100. When an operation is performed to instruct the execution of an external output test, the display unit 105 displays the confirmation screen 165 shown in Figure 8. The confirmation screen 165 includes a message asking whether it is OK to start the external output test and a "Yes" button 166. To start the external output test, the operator presses the "Yes" button 166.

[0048] In step S12, the transmitting unit 111 of the monitoring device 100 transmits to the smoke alarm panel 200 to which the dependent smoke sensor 300 subject to the external output test is connected the identifier of the dependent smoke sensor 300 subject to the external output test and a test start command instructing the start of the external output test at the target alarm level, in accordance with the operation performed in step S11. This test start command includes the target alarm level. For example, if the dependent smoke sensor 300 subject to the external output test is dependent smoke sensor 300A and the target alarm level is "Alarm 1", the monitoring device 100 transmits to the smoke alarm panel 200 to which the dependent smoke sensor 300A is connected the identifier of the dependent smoke sensor 300A and a test start command including the alarm level "Alarm 1". The transfer unit 211 of the smoke alarm panel 200 receives the identifier and the test start command from the monitoring device 100.

[0049] In step S13, the transmission unit 211 of the smoke alarm panel 200 transmits the received test start command to the dependent smoke sensor 300 that is the subject of the external output test. The destination of this test start command is identified using an identifier received along with the test start command. The acquisition unit 311 of the dependent smoke sensor 300 receives the test start command from the smoke alarm panel 200.

[0050] Figure 9 shows an example of the panel 250 of the smoke alarm panel 200. When the system receives a command to start an external output test, the panel 250 of the smoke alarm panel 200 displays information indicating that the external output test is in progress. In this example, the panel 250 includes an indicator light 251 for the "Test" button and an indicator light 252 labeled "Switch Caution". These indicator lights 251 and 252 are implemented, for example, by LEDs. When the command to start an external output test is received, the indicator light 251 for the "Test" button lights up and the indicator light 252 labeled "Switch Caution" blinks. These displays indicate that the external output test is in progress.

[0051] Returning to Figure 6, in step S14, when the dependent smoke sensor 300 receives the test start command, it switches to external output test mode. When it switches to external output test mode, the normal alarm operation does not occur.

[0052] In step S15, the test unit 312 of the dependent smoke sensor 300 performs a fire-related operation test according to the test start command. Specifically, the test unit 312 overwrites the smoke concentration stored in the memory unit 302 to the threshold of the target alarm level. This simulates an increase in smoke concentration to the threshold of the target alarm level. For example, if the target alarm level is "Alarm 1" and the threshold for the "Alarm 1" alarm level is 0.04% / m, the smoke concentration stored in the memory unit 302 is overwritten to 0.04% / m.

[0053] The determination unit 313 compares the smoke concentration stored in the memory unit 302 with the threshold values ​​for each alarm level from "Alarm 1" to "Alarm 3" to determine whether or not the smoke concentration corresponds to at least one of the alarm levels from "Alarm 1" to "Alarm 3". For example, if the smoke concentration stored in the memory unit 302 is overwritten to the threshold value for the alarm level "Alarm 1", the smoke concentration will be equal to or greater than the threshold value for the alarm level "Alarm 1", and therefore it will be determined that the smoke concentration corresponds to the alarm level "Alarm 1". Note that if there is an alarm level lower than the target alarm level, then if the smoke concentration corresponds to the target alarm level, it will also correspond to the lower alarm level.

[0054] In a fire test that does not involve output to the external equipment 500, the determination unit 313 performs an accumulation operation for the amount of time stored in the memory unit 302 before determining the alarm level. However, in an external output test that involves output to the external equipment 500, the determination unit 313 determines the alarm level without performing this accumulation operation. Specifically, the test unit 312 controls the determination unit 313 to use an accumulation time of 0 instead of the accumulation time stored in the memory unit 302. However, the accumulation time stored in the memory unit 302 itself is not overwritten. Under the control of the test unit 312, the determination unit 313 determines the alarm level using an accumulation time of 0, that is, without performing an accumulation operation. The fire test is performed in the same way as the external output test, by artificially increasing the smoke concentration to the threshold of each alarm level.

[0055] Figure 10 is a timing chart showing an example of the timing for determining the alarm level. In a fire test, as shown in Figure 10(a), the accumulation operation is performed for the accumulation time TA stored in the memory unit 302. For example, after the test starts at time t1, if the smoke concentration stored in the memory unit 302 is overwritten to the alarm level threshold of "Alarm 1" at time t2, the accumulation operation is performed from time t2 for the accumulation time TA. Since the smoke concentration stored in the memory unit 302 is maintained at the alarm level threshold of "Alarm 1", when the accumulation time TA has elapsed at time t3, it is determined that the alarm level corresponds to "Alarm 1". In this case, the time required from the start of the test until the alarm level is determined is the time TB from time t1 to time t3.

[0056] On the other hand, in the external output test, no storage operation is performed, as shown in Figure 10(b). For example, after the test is started at time t1, if the smoke concentration stored in the memory unit 302 is overwritten at time t2 to the threshold of the alarm level "Alarm 1", it is immediately determined that the alarm level "Alarm 1" is met. In this case, the time required from the start of the test until the alarm level is determined is the time TC from time t1 to time t2, which is shorter than the time TB shown in Figure 10(a).

[0057] Returning to Figure 6, in step S16, when the test performed in step S15 is completed, the transmitter 314 of the dependent smoke sensor 300 transmits the identifier of the dependent smoke sensor 300 and the test results to the smoke alarm panel 200 to which the dependent smoke sensor 300 is connected. These test results include the smoke concentration stored in the memory unit 302 and alarm information. The smoke concentration is an analog value. The alarm information indicates the corresponding alarm level. For example, the alarm information may be a 1-bit value indicating the corresponding alarm level. For example, the test results, which include a smoke concentration of 0.04% / m³ stored in the memory unit 302 of the dependent smoke sensor 300A and alarm information indicating the alarm level "Alarm 1", along with the identifier of the dependent smoke sensor 300A, are transmitted from the dependent smoke sensor 300A to the smoke alarm panel 200. The receiver 212 of the smoke alarm panel 200 receives the identifier and test results from the dependent smoke sensor 300.

[0058] In step S17, the receiving unit 212 of the smoke alarm panel 200 associates the identifier received from the dependent smoke sensor 300 with the test result and stores it in the storage unit 202.

[0059] In step S18, the display control unit 213 of the smoke alarm panel 200 reads the test results from the storage unit 202 and displays them on the display unit 206. These test results are displayed for each dependent smoke sensor 300 based on the associated identifier.

[0060] As shown in Figure 9, the panel surface 250 of the smoke alarm panel 200 is provided with sensor areas 253 equal to the number of dependent smoke sensors 300 connected to the smoke alarm panel 200. Each sensor area 253 includes a smoke concentration area 254, a bar graph 255, and alarm lights 256-258 labeled "Alarm 1" to "Alarm 3". The alarm lights 256-258 are implemented, for example, by LEDs.

[0061] The smoke concentration range 254 displays the smoke concentration measured by the dependent smoke sensor 300. The bar graph 255 displays a bar representing this smoke concentration. Alarm lights 256-258, labeled "Alarm 1" to "Alarm 3," illuminate when it is determined that the situation falls under "Alarm 1" to "Alarm 3," respectively.

[0062] The test results of the dependent smoke sensor 300A are displayed in the sensor area 253-1 corresponding to the dependent smoke sensor 300A. As described above, if the test results of the dependent smoke sensor 300A include a smoke concentration of 0.04% / m and alarm information indicating an alarm level of "Alarm 1", then the smoke concentration of 0.04% / m will be displayed in the smoke concentration area 254 of sensor area 253-1. The bar graph 255 of sensor area 253-1 will display a bar indicating a smoke concentration of 0.04% / m. The alarm light 256 labeled "Alarm 1" will illuminate. The alarm lights 257 labeled "Alarm 2" and 258 labeled "Alarm 3" will turn off. This display allows the worker to confirm that the alarm operation for the "Alarm 1" level was performed correctly in the external output test.

[0063] Returning to Figure 6, in step S19, the alarm transfer control unit 214 of the smoke alarm panel 200 refers to the alarm transfer database 221 stored in the memory unit 202 to determine whether or not an alarm transfer trigger assigned to the contacts of the alarm transfer circuit 207 has occurred.

[0064] For example, if the test results stored in the memory unit 202 do not include alarm information, the trigger for the transfer of information assigned to the contact has not occurred (the determination in step S19 is NO), so the process in step S20 described later is skipped and the process proceeds to step S21.

[0065] On the other hand, if, for example, the test results stored in the memory unit 202 include alarm information, and the alarm level indicated by this alarm information is assigned to at least one contact, then a trigger for reporting has occurred (the determination in step S19 is YES), and the process proceeds to step S20.

[0066] In step S20, the alarm transfer control unit 214 of the smoke alarm panel 200 activates a relay containing a contact to which the trigger for the generated alarm transfer has been assigned. This switches the connection state of the contacts in this relay, and a contact signal is output to the external equipment 500.

[0067] For example, consider a case where the test results of the dependent smoke sensor 300A include alarm information indicating that the alarm level corresponds to "Alarm 1". In the alarm transfer database 221 shown in Figure 4, the alarm level "Alarm 1" is assigned to the first contact. In this case, the alarm transfer control unit 214 supplies a signal to the alarm transfer circuit 207 to activate the first relay, which includes the first contact. This signal causes current to flow through the first coil included in the first relay. When current flows through the first coil, the second terminal of the first contact closes, and both ends of the second terminal become conductive. As a result, a contact signal is transmitted to the external equipment 500 connected to this second terminal.

[0068] When the external equipment 500 receives a contact signal, it performs a predetermined process. This predetermined process includes, for example, outputting sound, emitting light, operating, controlling other devices, displaying an alarm, or at least two of these combinations. This allows workers at the location where the external equipment 500 is installed to know that the alarm has been successfully transmitted from the smoke alarm panel 200 to the external equipment 500 in response to the alarm occurring.

[0069] In step S21, the transmission unit 211 of the smoke alarm panel 200 transmits the identifier and test result received from the dependent smoke sensor 300 to the monitoring device 100. The receiving unit 112 of the monitoring device 100 receives the identifier and test result from the smoke alarm panel 200.

[0070] In step S22, the receiving unit 112 of the monitoring device 100 associates the identifier received from the smoke alarm panel 200 with the test result and stores it in the storage unit 102.

[0071] In step S23, the display control unit 113 of the monitoring device 100 reads the test results from the storage unit 102 and displays them on the display unit 105. These test results are displayed for each dependent smoke sensor 300 based on the associated identifier.

[0072] In the monitoring screen 150 shown in Figure 7, the selection area 150b includes a selection button 152. The selection button 152 accepts the operation to select the smoke alarm panel 200. The display area 150c displays sensor areas 159, corresponding to the number of dependent smoke sensors 300 to be displayed. Each sensor area 159 includes a status display area 153, a smoke concentration area 154, a bar graph 155, and alarm symbols 156 to 158 labeled "Alarm 1" to "Alarm 3".

[0073] The status display area 153 displays the status of the dependent smoke sensor 300. While an external output test is being performed, the status display area 153 displays the status "External Output Test". The smoke concentration area 154 displays the smoke concentration measured by the dependent smoke sensor 300. The bar graph 155 displays a bar representing this smoke concentration. Alarm symbols 156 to 158, labeled "Alarm 1" to "Alarm 3", light up when the alarm level corresponds to "Alarm 1" to "Alarm 3", respectively. This lighting up means that the symbols are displayed in a conspicuous color such as red.

[0074] The test results of the dependent smoke sensor 300A are displayed in the sensor area 159-1 corresponding to the dependent smoke sensor 300A. If the test results of the dependent smoke sensor 300A include a smoke concentration of 0.04% / m³ and alarm information indicating an alarm level of "Alarm 1", then the smoke concentration of 0.04% / m³ is displayed in the smoke concentration area 154 of sensor area 159-1. The bar graph 155 of sensor area 159-1 displays a bar indicating a smoke concentration of 0.04% / m³. The alarm symbol 156 for "Alarm 1" is illuminated. The alarm symbols 157 for "Alarm 2" and 158 for "Alarm 3" are turned off. This turned-off display means that they are displayed in an inconspicuous color such as gray. This display allows the worker to confirm that the alarm operation for the alarm level "Alarm 1" was performed normally in the external output test.

[0075] Returning to Figure 6, in step S24, the transmitter 111 of the monitoring device 100 determines whether or not to change the alarm level and perform the next external output test. For example, if an operator performs an operation to change the alarm level and instruct the execution of the next external output test, the transmitter 111 determines to change the alarm level and perform the next external output test (the determination in step S24 is YES). In this case, the process returns to step S12 described above, and the process from step S12 onward is carried out with the changed alarm level as the target alarm level.

[0076] Figure 11 shows an example of a notification screen 170 displayed on the display unit 105 of the monitoring device 100 while an external output test is being performed. During an external output test at the alarm level "Alarm 1", the notification screen 170A shown in Figure 11(a) is displayed. Notification screen 170A includes the alarm level "Alarm 1" and a message indicating that an external output test is being performed. Notification screen 170A also accepts an operation to instruct the dependent smoke sensor 300, which is the target of the external output test, to start an external output test at the next highest alarm level after "Alarm 1", "Alarm 2". In this example, notification screen 170A includes a message asking whether to change to the alarm level "Alarm 2" and a "Yes" button 171. To then start the external output test at the alarm level "Alarm 2", the worker presses the "Yes" button 171.

[0077] In response to this operation, the monitoring device 100 sends a test start command, including the alarm level "Alarm 2," to the dependent smoke sensor 300A via the smoke alarm panel 200. Upon receiving the test start command, the dependent smoke sensor 300A continues in test mode and performs a test at the alarm level "Alarm 2." Here, the threshold for the alarm level "Alarm 2" is assumed to be 0.06% / m. In this case, the smoke concentration stored in the memory unit 302 is rewritten to 0.06% / m. Subsequently, without any storage operation, it is determined that the alarm levels "Alarm 1" and "Alarm 2" are met. Then, the test result, including the smoke concentration of 0.06% / m and alarm information indicating the alarm levels "Alarm 1" and "Alarm 2," is sent from the dependent smoke sensor 300A to the smoke alarm panel 200. The smoke alarm panel 200 stores this test result in the memory unit 202 and displays it on the display unit 206, similar to the example shown in Figure 9. Furthermore, in the transmission database 221 shown in Figure 4, an alarm level called "Alarm 2" is assigned to the second contact. Therefore, in addition to the already activated first contact, the second relay, including the second contact, is activated, and a contact signal is transmitted to the external equipment 500 connected to the second contact. In addition, this test result is transmitted from the smoke alarm panel 200 to the monitoring device 100. The monitoring device 100 stores this test result in the storage unit 102 and displays it on the display unit 105, similar to the example shown in Figure 7.

[0078] While the external output test at the alarm level "Alarm 2" is being performed, the display unit 105 of the monitoring device 100 displays the notification screen 170B shown in Figure 11(b). The notification screen 170B includes a message indicating that the alarm level is "Alarm 2" and that the external output test is in progress. The notification screen 170B also accepts an operation to instruct the dependent smoke sensor 300, which is the target of the external output test, to start the external output test at "Alarm 3," the next highest alarm level after "Alarm 2." In this example, the notification screen 170B includes a message asking whether to change to the alarm level "Alarm 3" and a "Yes" button 172. To proceed with the external output test at the alarm level "Alarm 3," the worker presses the "Yes" button 172.

[0079] In response to this operation, the monitoring device 100 sends a test start command, including the alarm level "Alarm 3," to the dependent smoke sensor 300A via the smoke alarm panel 200. Upon receiving the test start command, the dependent smoke sensor 300A continues in test mode and performs a test at the alarm level "Alarm 3." Here, the threshold for the alarm level "Alarm 3" is assumed to be 0.08% / m. In this case, the smoke concentration stored in the memory unit 302 is overwritten to 0.08% / m. Subsequently, without any storage operation, it is determined that the alarm levels "Alarm 1" to "Alarm 3" apply. Then, the test result, including the smoke concentration of 0.08% / m and alarm information indicating the alarm levels "Alarm 1" to "Alarm 3," is transmitted from the dependent smoke sensor 300A to the smoke alarm panel 200. The smoke alarm panel 200 stores this test result in the memory unit 202 and displays it on the display unit 206, similar to the example shown in Figure 9. Furthermore, in the transmission database 221 shown in Figure 4, an alarm level called "Alarm 3" is assigned to the third contact. Therefore, in addition to the already activated first and second contacts, the third relay, including the third contact, is activated, and a contact signal is transmitted to the external equipment 500 connected to the third contact. In addition, this test result is transmitted from the smoke alarm panel 200 to the monitoring device 100. The monitoring device 100 stores this test result in the storage unit 102 and displays it on the display unit 105, similar to the example shown in Figure 7.

[0080] Returning to Figure 6, if the operator instructs the termination of the external output test in step S24 described above, the transmission unit 111 determines that it will not perform the next external output test (the determination in step S24 is NO). In this case, the process proceeds to step S25.

[0081] For example, while an external output test is being performed at an alarm level of "Alarm 3," the display unit 105 of the monitoring device 100 displays the notification screen 170C shown in Figure 11(c). The notification screen 170C includes a message indicating that the alarm level is "Alarm 3" and that an external output test is in progress. The notification screen 170C also accepts an operation to signal the termination of the external output test. In this example, the notification screen 170C includes a "Test Termination" button 173. To terminate the external output test, the worker presses the "Test Termination" button 173. When the "Test Termination" button 173 is pressed, it is determined that no further external output tests will be performed.

[0082] Returning to Figure 6, in step S25, the transmitter 111 of the monitoring device 100 transmits to the smoke alarm panel 200 to which the dependent smoke sensor 300 subject to the external output test is connected the identifier of the dependent smoke sensor 300 subject to the external output test and a test completion command instructing the end of the external output test at the target alarm level. For example, the identifier of the dependent smoke sensor 300A and the test completion command are transmitted from the monitoring device 100 to the smoke alarm panel 200 to which the dependent smoke sensor 300A is connected. The transfer unit 211 of the smoke alarm panel 200 receives the identifier and the test completion command from the monitoring device 100.

[0083] In step S26, the transfer unit 211 of the smoke alarm panel 200 transmits the received test completion command to the dependent smoke sensor 300 that is the subject of the external output test. The destination of this test start command is identified using the identifier received together with the test completion command. The acquisition unit 311 of the dependent smoke sensor 300 receives the test completion command from the smoke alarm panel 200.

[0084] Furthermore, upon receiving the test completion command for the external output test, the indicator lights 251 for the "Test" button and 252 for the "Switch Caution" button, as shown in Figure 9, turn off on the panel 250 of the smoke alarm panel 200. In addition, the operation of the first to third contacts is released, and the transmission of contact signals to the external equipment 500 stops.

[0085] In step S27, when the dependent smoke sensor 300 receives the test completion command, it returns from external output test mode to normal alarm mode. This resumes normal alarm operation. In normal alarm mode, the smoke concentration is measured by the smoke detection unit 304 at predetermined time intervals, and this smoke concentration is stored in the storage unit 302. Subsequently, it is determined whether the smoke concentration stored in the storage unit 302 corresponds to at least one of the alarm levels from "Alarm 1" to "Alarm 3". Then, the smoke detection result, including the smoke concentration stored in the storage unit 302 and alarm information indicating the corresponding alarm level, is transmitted to the smoke alarm panel 200. If the smoke detection result received from the dependent smoke sensor 300 includes alarm information, an alarm corresponding to the alarm level indicated by that alarm information is output from the smoke alarm panel 200. In addition, a contact corresponding to the alarm level is activated, and a contact signal is transmitted to the external equipment 500 connected to the activated contact.

[0086] According to the embodiment described above, since the storage operation is not performed in the dependent smoke sensor 300 during the external output test, the time required for the external output test is shortened. In particular, when external output tests are performed sequentially at multiple alarm levels, from "Alarm 1" to "Alarm 3," the storage operation is omitted in each of these alarm levels, so the time from the start of the external output test at alarm level "Alarm 1" to the end of the external output test at alarm level "Alarm 3" is significantly shortened. Furthermore, in the embodiment described above, the storage time set in the dependent smoke sensor 300 is not changed during the external output test. If the storage time set in the dependent smoke sensor 300 were changed to 0 when the external output test is performed, then, for example, if a worker forgets to reset the storage time to its original setting after the external output test, the storage operation will not be performed during the fire test. However, in the embodiment described above, since the storage time set in the dependent smoke sensor 300 is not changed during the external output test, the storage operation will be performed during the fire test even if the worker does not reset the storage time. Therefore, it is possible to prevent the accumulation operation from failing to be performed during the fire test due to forgetting to reset the accumulation time. Furthermore, since the monitoring device 100 accepts an operation to instruct the execution of the external output test, the worker can instruct the execution of the external output test by operating the monitoring device 100.

[0087] Furthermore, since external output tests are performed separately for alarm levels "Alarm 1" to "Alarm 3," it is possible to individually verify whether the first to third contacts, to which each alarm level "Alarm 1" to "Alarm 3" is assigned, are functioning correctly. For example, if alarm levels "Alarm 1" to "Alarm 3" are each assigned to the first to third contacts, then when an external output test is performed for alarm level "Alarm 3," it will be determined that all alarm levels from "Alarm 1" to "Alarm 3" are met, and contact signals will be output to the external equipment 500 connected to the first to third contacts. However, in this example, it may not be possible to determine whether the output of the contact signals to the external equipment 500 was triggered by reaching alarm level "Alarm 1," alarm level "Alarm 2," or alarm level "Alarm 3." However, by performing separate external output tests for each alarm level, from "Alarm 1" to "Alarm 3," it is possible to individually verify whether a contact signal was properly output to the external equipment 500 upon reaching each of the alarm levels, from "Alarm 1" to "Alarm 3."

[0088] Variation The present invention is not limited to the embodiments described above. The embodiments described above may be modified and implemented as shown in the following modifications. The embodiments and modifications may be used in combination or switched between depending on the application. Similarly, the following modifications may be used in combination or switched between depending on the application.

[0089] Variation 1 In the embodiment described above, the smoke monitoring system 10 may include one or more independent smoke sensors 400 that output a signal to an external device 500. The independent smoke sensors 400 are connected to the monitoring device 100 via a first signal line 11. The independent smoke sensors 400 are also connected to the external device 500 via a fourth signal line.

[0090] The standalone smoke sensor 400, also known as a standalone smoke sensor, is a smoke sensor that operates independently without requiring the smoke alarm panel 200. "Operating independently" here means that it can provide smoke alarm functionality without relying on other devices. The standalone smoke sensor 400 detects smoke in the surroundings and outputs an alarm according to the smoke detection result. The standalone smoke sensor 400 also performs tests according to the instructions of the monitoring device 100.

[0091] Figure 12 shows an example of the configuration of an independent smoke sensor 400. The independent smoke sensor 400 comprises a control unit 401, a storage unit 402, a communication unit 403, a smoke detection unit 404, an operation unit 405, a display unit 406, and a transmission circuit 407. Each part of the independent smoke sensor 400 is connected via a bus.

[0092] The control unit 401, storage unit 402, communication unit 403, smoke detection unit 404, operation unit 405, display unit 406, and alarm transfer circuit 407 are basically the same as the control unit 101, storage unit 102, and communication unit 103 of the monitoring device 100, the smoke detection unit 304 of the dependent smoke sensor 300, the operation unit 205, display unit 206, and alarm transfer circuit 207 of the smoke alarm panel 200, respectively. The alarm transfer circuit 407 is an example of an "output unit" according to the present invention. However, in addition to the program for realizing the functions of the independent smoke sensor 400, the storage unit 402 stores a preset storage time for the independent smoke sensor 400 and an alarm transfer database 421 similar to the alarm transfer database 221 shown in Figure 4. The smoke concentration measured by the smoke detection unit 404 is also stored in the storage unit 402.

[0093] The control unit 401 functions as an acquisition unit 411, a test unit 412, a determination unit 413, a transmission unit 414, a display control unit 415, and a transmission control unit 416. These functions are realized when the control unit 401 executes a program stored in the storage unit 402, performs calculations, or controls each part of the independent smoke sensor 400.

[0094] The acquisition unit 411, test unit 412, determination unit 413, transmission unit 414, display control unit 415, and alarm transfer control unit 416 are basically the same as the acquisition unit 311, test unit 312, determination unit 313, and transmission unit 314 of the dependent smoke sensor 300, and the display control unit 213 and alarm transfer control unit 214 of the smoke alarm panel 200, respectively. However, the acquisition unit 311 acquires an instruction to execute an external output test from the monitoring device 100 or in response to an operation of the operation unit 405. The transmission unit 414 transmits the test results to the monitoring device 100.

[0095] In the first example of this modified configuration, the monitoring device 100 issues an instruction to the independent smoke sensor 400 to perform an external output test. Here, the independent smoke sensor 400 is assumed to include the independent smoke sensor 400A. For example, when performing an external output test at an alarm level of "Alarm 1" on the independent smoke sensor 400A, the worker uses the "Test" button 151 on the monitoring screen 150 shown in Figure 7 to select the independent smoke sensor 400A and instructs the execution of an external output test at an alarm level of "Alarm 1".

[0096] In response to this operation, the monitoring device 100 sends a test start command to the independent smoke sensor 400A, which includes the alarm level "Alarm 1". Upon receiving the test start command, the independent smoke sensor 400A switches to test mode and performs a test at the alarm level "Alarm 1" without performing any storage operations. If the test determines that the alarm level "Alarm 1" is met, the connection state of the contacts of the transmission circuit 407 to which that alarm level is assigned is switched, and a contact signal is sent to the external equipment 500 connected to these contacts. The test result is also sent from the independent smoke sensor 400A to the monitoring device 100. The monitoring device 100 stores this test result in the storage unit 102 and displays it on the display unit 105, similar to the example shown in Figure 7.

[0097] In a second example of this modification, an instruction to perform an external output test is given using the operating unit 405 of the independent smoke sensor 400, without using the monitoring device 100. For example, when performing an external output test at an alarm level of "Alarm 1" on the independent smoke sensor 400A, the worker uses the operating unit 405 of the independent smoke sensor 400A to instruct the execution of an external output test at an alarm level of "Alarm 1".

[0098] In response to this operation, a test start command including the alarm level "Alarm 1" is input to the standalone smoke sensor 400A. Upon receiving the test start command, the standalone smoke sensor 400A enters test mode and performs a test at the alarm level "Alarm 1" without performing any accumulation operations. If the test determines that the alarm level "Alarm 1" is met, the connection state of the contacts of the transmission circuit 407 to which that alarm level is assigned is switched, and a contact signal is transmitted to the external equipment 500 connected to these contacts. The test result is also displayed on the display unit 406.

[0099] According to this modified version, no accumulation operation is performed even during the external output test from the independent smoke sensor 400 to the external equipment 500, thus shortening the time required for this external output test.

[0100] Variation 2 In the embodiments or modifications described above, the storage time used in the external output test does not necessarily have to be zero. For example, in the external output test, a storage time shorter than the storage time used in the fire test may be used. For example, if the storage time set for the dependent smoke sensor 300 or the independent smoke sensor 400 is 20 seconds, in the external output test, the storage operation may be performed using a time obtained by subtracting a predetermined amount from this storage time, for example, 5 seconds. This modification also shortens the time required for the external output test.

[0101] Variation 3 In the embodiments or modifications described above, the monitoring device 100 may be used as a setting tool. In this modification, the monitoring device 100 may be, for example, a portable computer carried by a worker. The monitoring device 100 is individually connected to the smoke alarm panel 200, the dependent smoke sensor 300, or the independent smoke sensor 400 via a fifth signal line such as a USB (Universal Serial Bus) cable. When connected to the target device via the fifth signal line, the monitoring device 100 exchanges various types of data with the target device via the fifth signal line.

[0102] Variation 4 In the embodiments or modifications described above, the contacts included in the alarm transfer circuit 207 or 407 may be c-contacts, a-contacts, or b-contacts. The relay may be a contact relay or a non-contact relay. Furthermore, the number of contacts included in the alarm transfer circuit 207 or 407 may be less than or more than three. Moreover, not all alarm levels "Alarm 1" to "Alarm 3" are assigned to contacts. Only one or two of the multiple alarm levels "Alarm 1" to "Alarm 3" are assigned to contacts.

[0103] Variation 5 In the embodiments or modifications described above, there may be multiple external devices 500. In this case, at least one of the multiple contacts included in the alarm transmission circuit 207 or 407 may be connected to an external device 500 different from the other contacts, or multiple contacts may each be connected to a different external device 500. Furthermore, the contacts and the external devices 500 may be connected by wire or wirelessly.

[0104] Variation 6 In the embodiments or modifications described above, if the smoke concentration is above the threshold for the alarm level "Alarm 2", it does not necessarily have to correspond to the alarm level "Alarm 1". For example, if the smoke concentration is above the threshold for the alarm level "Alarm 2", it may be determined to correspond only to the alarm level "Alarm 2". Similarly, if the smoke concentration is above the threshold for the alarm level "Alarm 3", it does not necessarily have to correspond to the alarm levels "Alarm 1" and "Alarm 2". If the smoke concentration is above the threshold for the alarm level "Alarm 3", it may be determined to correspond only to the alarm level "Alarm 3".

[0105] Variation 7 In the embodiments or modifications described above, the number of alarm levels is not limited to three. The number of alarm levels may be two, four or more.

[0106] Variation 8 In the embodiments or modifications described above, the smoke alarm panel 200 may receive an operation to instruct the execution of an external output test together with or instead of the monitoring device 100, and transmit a test start command to the dependent smoke sensor 300 in response to this operation.

[0107] Modification 9 In the embodiments or modifications described above, the configuration of the various screens displayed on the monitoring device 100 and the panel 250 of the smoke alarm panel 200 is not limited to the examples described above. The monitoring screen 150 and the panel 250 may have any configuration as long as they can display the test results of the dependent smoke sensor 300 or the independent smoke sensor 400. This configuration includes color, arrangement, shape, components, and screen transitions. Furthermore, the monitoring screen 150 may have any configuration as long as it can accept an operation to instruct the execution of an external output test. For example, the monitoring screen 150 may be configured to include operation images different from the operation images described in the embodiments described above, or it may be configured to omit some of the operation images.

[0108] Variation 10 In the embodiments or modifications described above, the configuration of the smoke monitoring system 10 is not limited to the examples described above. The smoke monitoring system 10 may be configured to include one or more of the devices described above, or it may be configured to omit some of the devices. For example, the smoke monitoring system 10 may include a monitoring device 100, a smoke alarm panel 200, a dependent smoke sensor 300, and an independent smoke sensor 400. Alternatively, the smoke monitoring system 10 may include only the independent smoke sensor 400. Furthermore, the main body having the function of the smoke monitoring system 10 is not limited to the examples described above.

[0109] Variation 11 In the embodiments or modifications described above, the operation of the smoke monitoring system 10 is not limited to the examples described above. The processing steps of the smoke monitoring system 10 may be rearranged as long as they do not contradict each other. In addition, some of the processing steps of the smoke monitoring system 10 may be omitted.

[0110] Variation 12 Another embodiment of the present invention may provide a method having steps of processing performed in at least one of the following: smoke monitoring system 10, monitoring device 100, smoke alarm panel 200, dependent smoke sensor 300, and independent smoke sensor 400. Yet another embodiment of the present invention may provide a program to be executed in the monitoring device 100, smoke alarm panel 200, dependent smoke sensor 300, or independent smoke sensor 400. This program may be provided stored on a computer-readable recording medium or provided by download via the Internet or the like. [Explanation of symbols]
