[0009] composition FIG. 1 is a diagram showing an example of the configuration of a smoke monitoring system 10 according to an embodiment. The smoke monitoring system 10 is installed in a fire-prevention object such as a server room, a data center, or a clean room. The smoke monitoring system 10 detects signs of fire by monitoring the state of the ambient air in the fire-prevention object. In this way, detecting signs of fire makes it possible to quickly respond at an early stage.

[0010] The smoke monitoring system 10 includes a monitoring device 100, a smoke alarm panel 200, and a plurality of slave 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 smoke alarm panel 200 is connected to a plurality of slave smoke sensors 300 via a second signal line 12. The smoke alarm panel 200 is also connected to an external device 500 via a third signal line 13. Although only one smoke alarm panel 200 is shown in FIG. 1, a plurality of smoke alarm panels 200 may be provided.

[0011] In the smoke monitoring system 10, a fire test and an external output test are performed at a predetermined time, such as at the time of installation or maintenance. The fire test is a test to check whether the dependent smoke sensor 300 operates normally. In the fire test, no output is made to the external equipment 500. The external output test is also called a facing test, and is a test to check whether the operation of transferring a signal to the external equipment 500 in response to the determination of a fire by the dependent smoke sensor 300 is performed normally. This transfer of a signal means transmitting an alarm. In the external output test, an output is made to the external equipment 500. During the external output test, a person needs to be present at the external equipment 500 to check whether the signal has been transferred to the external equipment 500. For this reason, it is preferable that the time required for the external output test is short.

[0012] The monitoring device 100 is used to collectively monitor the smoke alarm panel 200 and the slave smoke sensor 300. The monitoring device 100 also instructs the smoke alarm panel 200 and the slave smoke sensor 300 to execute an external output test.

[0013] The smoke alarm panel 200 is a device that receives smoke detection results from the slave smoke sensor 300 and outputs an alarm in response to the smoke detection results. The output of this alarm includes transmission of the alarm to an external facility 500.

[0014] The dependent smoke sensor 300 is also called a communication type smoke sensor, and is a smoke sensor that is dependent on the smoke alarm panel 200. The term "dependent" here means that the smoke alarm panel 200 is responsible for part of the smoke alarm function. The dependent smoke sensor 300 detects surrounding smoke and transmits the smoke detection result to the smoke alarm panel 200. The dependent smoke sensor 300 also performs tests according to instructions from the monitoring device 100.

[0015] The external equipment 500 is an external equipment to which a report is transferred from the smoke alarm panel 200 in response to the occurrence of an alarm. The external equipment 500 includes, for example, warning lights, fire extinguishing equipment, disaster prevention control panels, broadcasting equipment, security company equipment, and other equipment.

[0016] 2 is a diagram showing an example of the configuration of the monitoring device 100. For example, a general-purpose computer is used as the monitoring device 100. 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. The various units of the monitoring device 100 are connected via a bus.

[0017] The control unit 101 is a processor that controls each part of the device and performs various processes. 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 implementing the functions of the device. The storage unit 102 includes, for example, at least one of a ROM (Read Only Memory), an EPROM (Erasable Programmable ROM), an EEPROM (Electrically Erasable Programmable ROM), and a 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 transmission unit 111, a reception unit 112, and a display control unit 113. These functions are realized by the control unit 101 executing a program stored in the storage unit 102, and the control unit 101 performing calculations or controlling each unit of the monitoring device 100.

[0019] The transmission unit 111 transmits an instruction to execute an external output test at each of the multiple alarm levels to the smoke alarm panel 200 in response to an operation to instruct execution of an external output test at each of the multiple alarm levels. The multiple alarm levels indicate that the smoke concentration is equal to or greater than different threshold values. In one example, the multiple alarm levels are three levels of alarm 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 slave smoke sensor 300 in accordance with the execution instruction transmitted from the transmitter 111 , the receiver 112 receives the result of this test from the slave 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] 3 is a diagram showing an example of the configuration of a smoke alarm panel 200. The smoke alarm panel 200 includes a control unit 201, a memory unit 202, a first communication unit 203, a second communication unit 204, an operation unit 205, a display unit 206, and a reporting circuit 207. The various units of the smoke alarm panel 200 are connected via a bus.

[0023] The control unit 201, the storage unit 202, the first communication unit 203, the operation unit 205, and the display unit 206 are basically the same as the control unit 101, the storage unit 102, the communication unit 103, the operation unit 104, and the display unit 105 of the monitoring device 100, respectively. However, the storage unit 202 stores a report database 221 in addition to a program for realizing the function of the smoke alarm panel 200. The operation unit 205 includes, for example, an operation button. 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 itself 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 report transfer circuit 207 transfers a report to the external equipment 500 when an alarm occurs. The report transfer circuit 207 is an example of the "output unit" according to the present invention. The report transfer circuit 207 includes a plurality of relays. Each relay includes a coil and a contact. In one example, the report transfer circuit 207 includes a first relay to a third relay. The first relay to the third relay 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 report transfer circuit 207 are connected to the external equipment 500 via the third signal line 13. A signal or alarm level that triggers report transfer is assigned to these contacts in advance. Each contact includes a first terminal and a second terminal. Normally, no current flows through the coil, so the first terminal is closed and the second terminal is open. On the other hand, when a report transfer trigger assigned to a contact occurs and a current flows through the paired 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 report transfer control unit 214. These functions are realized by the control unit 201 executing a program stored in the storage unit 202, and the control unit 201 performing calculations or controlling each unit 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 slave smoke sensor 300. In addition, the transfer unit 211 transfers the test result transmitted from the slave smoke sensor 300 to the monitoring device 100.

[0028] When a test is performed by the slave smoke sensor 300, the receiver 212 receives the result of the test from the slave 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 report transfer control unit 214 outputs a contact signal to the external equipment 500 by switching the connection state of the contact of the report transfer circuit 207 in accordance with the test result received by the receiving unit 212 .

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

[0032] Here, alarm levels "ALARM 1" to "ALARM 3" are assigned to the first to third contacts included in the report transfer circuit 207, respectively. In this case, as shown in Fig. 4, the identifier of the first contact and the alarm level "ALARM 1" are stored in association with each other. The identifier of the second contact and the alarm level "ALARM 2" are stored in association with each other. Furthermore, the identifier of the third contact and the alarm level "ALARM 3" are stored in association with each other.

[0033] 5 is a diagram showing an example of the configuration of the dependent smoke sensor 300. The dependent smoke sensor 300 includes a control unit 301, a storage unit 302, a communication unit 303, and a smoke detection unit 304. The respective units of the dependent smoke sensor 300 are connected via a bus.

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

[0035] The smoke detection unit 304 sucks in the surrounding air and measures the smoke concentration. In this way, the smoke detection unit 304 detects smoke present in the surrounding air. The smoke concentration that the smoke detection unit 304 can measure ranges from 0.0001% / m to 20.0% / m, for example. For example, a total scattered light method or a two-light receiving method is used to detect smoke. 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 memory unit 302.

[0036] The control unit 301 functions as an acquisition unit 311, a test unit 312, a determination unit 313, and a transmission unit 314. These functions are realized by the control unit 301 executing a program stored in the storage unit 302, and the control unit 301 performing calculations or controlling each unit of the dependent smoke sensor 300.

[0037] When an instruction to execute an external output test at each of a plurality of alarm levels is transmitted from the monitoring device 100, the acquisition unit 311 acquires this execution instruction via the smoke alarm panel 200.

[0038] The test unit 312 performs a test of a fire-related operation at each of a plurality of alarm levels in accordance with the execution instruction acquired by the acquisition unit 311, without performing an accumulation operation for a predetermined time that is performed in a fire test that does not involve an output to the external equipment 500. The fire-related operation includes an operation that is performed when a fire occurs and an operation that is performed when a fire symptom occurs. The test unit 312 may perform a fire test in addition to an external output test. In this case, the test unit 312 does not perform an accumulation operation during the external output test, and performs an accumulation operation during the fire test.

[0039] In the dependent smoke sensor 300, different thresholds are preset for each of a plurality of alarm levels. For example, the thresholds of the alarm levels "alarm 1" to "alarm 3" are set in the range of 0.01% / m to 20.0% / m so that the threshold of the alarm level "alarm 1" is larger than the threshold of the alarm level "alarm 2" and the threshold of the alarm level "alarm 3". The thresholds set in this manner are stored in the storage unit 302. The test unit 312 executes a test of the operation related to a fire at the target alarm level by artificially increasing the smoke concentration to the threshold of the target alarm level. In addition, the test unit 312 controls the determination unit 313 not to perform the accumulation operation in the external output test.

[0040] The determination unit 313 determines the corresponding alarm level by comparing the smoke concentration stored in the storage unit 302 with the thresholds of the alarm levels "Alarm 1" to "Alarm 3". For example, when the smoke concentration is less than the threshold of the alarm level "Alarm 1", the determination unit 313 determines that the smoke concentration does not correspond to any of the alarm levels "Alarm 1" to "Alarm 3". When the smoke concentration is equal to or greater than the threshold of the alarm level "Alarm 1", the determination unit 313 determines that the smoke concentration corresponds to the alarm level "Alarm 1". When the smoke concentration is equal to or greater than the threshold of the alarm level "Alarm 2", the determination unit 313 determines that the smoke concentration corresponds to the alarm level "Alarm 2". When the smoke concentration is equal to or greater than the threshold of the alarm level "Alarm 3", the determination unit 313 determines that the smoke concentration corresponds to the alarm level "Alarm 3".

[0041] Here, in a fire test that does not involve output to external equipment 500, determination unit 313 performs an accumulation operation for the accumulation time stored in memory unit 302 and then determines the alarm level. For example, when the accumulation time is 20 seconds, accumulation operation is performed for 20 seconds from the time when the smoke concentration stored in memory unit 302 first becomes equal to or greater than the threshold of the target alarm level. Then, when the accumulation time has elapsed, if the smoke concentration stored in memory unit 302 is equal to or greater than the threshold of the target alarm level, determination unit 313 determines that the alarm level corresponds to the target alarm level. On the other hand, in an external output test that involves output to external equipment 500, determination unit 313, under the control of test unit 312, determines the alarm level without performing this accumulation operation.

[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 indicate the concentration of smoke stored in the memory unit 302 and the corresponding alarm level determined by the determining unit 313.

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

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

[0045] FIG. 7 is a diagram showing 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 in response to, for example, an operation by an operator. As shown in FIG. 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 a target alarm level from among "Alarm 1" to "Alarm 3" and to instruct execution of an external output test. This operation is realized by the operation unit 104.

[0046] Here, the multiple dependent smoke sensors 300 include the dependent smoke sensor 300A. For example, when first performing an external output test at an alarm level of "alarm 1" on the dependent smoke sensor 300A, an operator uses the "test" button 151 on the monitoring screen 150 shown in Fig. 7 to select the dependent smoke sensor 300A and perform an operation to instruct execution of an external output test at an alarm level of "alarm 1".

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

[0048] In step S12, the transmission unit 111 of the monitoring device 100 transmits, in response to the operation performed in step S11, to the smoke alarm panel 200 to which the dependent smoke sensor 300 to be subjected to the external output test is connected, an identifier of the dependent smoke sensor 300 to be subjected to the external output test, and a test start command for instructing the start of an external output test at the target alarm level. The target alarm level is included in this test start command. For example, if the dependent smoke sensor 300 to be subjected to the external output test is the dependent smoke sensor 300A, and the target alarm level is "alarm 1", the monitoring device 100 transmits a test start command including the identifier of the dependent smoke sensor 300A and the alarm level of "alarm 1" 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 start command from the monitoring device 100.

[0049] In step S13, the transfer unit 211 of the smoke alarm panel 200 transmits the received test start command to the dependent smoke sensor 300 that is the target of the external output test. The destination of this test start command is specified by using the identifier received together 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] 9 is a diagram showing an example of the panel 250 of the smoke alarm panel 200. When a test start command for an external output test is received, information indicating that an external output test is being performed is displayed on the panel 250 of the smoke alarm panel 200. In this example, the panel 250 includes an indicator light 251 for a "Test" button and an indicator light 252 for "Caution Switch". These indicator lights 251 and 252 are realized by, for example, LEDs. When a test start command for an external output test is received, the indicator light 251 for the "Test" button lights up and the indicator light 252 for "Caution Switch" flashes. These displays indicate that an external output test is being performed.

[0051] 6, in step S14, when the slave smoke sensor 300 receives the test start command, the slave smoke sensor 300 transitions to the external output test mode. When the slave smoke sensor 300 transitions to the external output test mode, the normal alarm operation is not performed.

[0052] In step S15, the test unit 312 of the dependent smoke sensor 300 performs a test of a fire-related operation in accordance with the test start command. Specifically, the test unit 312 rewrites the smoke concentration stored in the memory unit 302 to the threshold of the target alarm level. This artificially increases the smoke concentration to the threshold of the target alarm level. For example, if the target alarm level is "alarm 1" and the threshold of the alarm level "alarm 1" is 0.04% / m, the smoke concentration stored in the memory unit 302 is rewritten to 0.04% / m.

[0053] The determination unit 313 compares the smoke concentration stored in the memory unit 302 with each threshold of the alarm levels "Alarm 1" to "Alarm 3" to determine whether or not the smoke concentration corresponds to at least one of the alarm levels "Alarm 1" to "Alarm 3". For example, if the smoke concentration stored in the memory unit 302 is rewritten to the threshold of the alarm level "Alarm 1", the smoke concentration will be equal to or greater than the threshold of the alarm level "Alarm 1", and therefore it is 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 when the smoke concentration corresponds to the target alarm level, it also corresponds to an alarm level lower than the target alarm level.

[0054] Here, in a fire test that does not involve output to the external equipment 500, the judgment unit 313 performs an accumulation operation for the accumulation time stored in the memory unit 302 and then judges the alarm level. However, in an external output test that involves output to the external equipment 500, the judgment unit 313 judges the alarm level without performing this accumulation operation. Specifically, the test unit 312 controls the judgment unit 313 to use an accumulation time of 0 instead of the accumulation time stored in the memory unit 302. However, the accumulation time itself stored in the memory unit 302 is not rewritten. Under the control of the test unit 312, the judgment unit 313 uses the accumulation time of 0, that is, judges the alarm level without performing an accumulation operation. Note that the fire test is performed by artificially increasing the smoke concentration to the threshold value of each alarm level, similar to the external output test.

[0055] FIG. 10 is a timing chart showing an example of the timing of judging the alarm level. In the fire test, as shown in FIG. 10(a), the accumulation operation is performed for the accumulation time TA stored in the memory unit 302. For example, after the test is started at time t1, if the smoke concentration stored in the memory unit 302 is rewritten to the threshold of the alarm level "alarm 1" at time t2, the accumulation operation is performed for the accumulation time TA from time t2. Since the smoke concentration stored in the memory unit 302 remains at the threshold of the alarm level "alarm 1", it is judged to correspond to the alarm level "alarm 1" when the accumulation time TA has elapsed at time t3. In this case, the time required from the start of the test until the alarm level is judged is the time TB from time t1 to time t3.

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

[0057] Returning to FIG. 6, in step S16, when the test performed in step S15 is completed, the transmitting unit 314 of the dependent smoke sensor 300 transmits the identifier of the dependent smoke sensor 300 and the test result to the smoke alarm panel 200 to which the dependent smoke sensor 300 is connected. The test result includes the smoke concentration stored in the memory unit 302 and the 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 result including the smoke concentration of 0.04% / m stored in the memory unit 302 of the dependent smoke sensor 300A and the alarm information indicating the alarm level of "alarm 1", and the identifier of the dependent smoke sensor 300A are transmitted from the dependent smoke sensor 300A to the smoke alarm panel 200. The receiving unit 212 of the smoke alarm panel 200 receives the identifier and the test result from the dependent smoke sensor 300.

[0058] In step S17, the receiving section 212 of the smoke alarm panel 200 associates the identifier received from the slave smoke sensor 300 with the test result and stores them in the memory section 202.

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

[0060] 9, the panel surface 250 of the smoke alarm panel 200 is provided with sensor areas 253 equal to the number of slave 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"-"ALARM 3." The alarm lights 256-258 are realized by, for example, LEDs.

[0061] The smoke density area 254 displays the smoke density measured by the slave smoke sensor 300. The bar graph 255 displays a bar indicating the smoke density. The warning lights 256-258 labeled "Alarm 1"-"Alarm 3" are turned on when it is determined that the smoke corresponds to "Alarm 1"-"Alarm 3," respectively.

[0062] The test result of the dependent smoke sensor 300A is displayed in the sensor area 253-1 corresponding to the dependent smoke sensor 300A. As described above, if the test result of the dependent smoke sensor 300A includes a smoke density of 0.04% / m and alarm information indicating an alarm level of "alarm 1", the smoke density of 0.04% / m is displayed in the smoke density area 254 of the sensor area 253-1. A bar indicating the smoke density of 0.04% / m is displayed in the bar graph 255 of the sensor area 253-1. The alarm light 256 of "alarm 1" is turned on. The alarm light 257 of "alarm 2" and the alarm light 258 of "alarm 3" are turned off. This display allows the operator to confirm that the alarm operation of the alarm level of "alarm 1" was performed normally in the external output test.

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

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

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

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

[0067] For example, assume that the test result of the dependent smoke sensor 300A includes alarm information indicating that the alarm level is "alarm 1." In the report transfer database 221 shown in FIG. 4, the alarm level "alarm 1" is assigned to the first contact. In this case, the report transfer control unit 214 supplies a signal to the report transfer circuit 207 to activate the first relay including the first contact. This signal causes a current to flow through the first coil included in the first relay. When a current flows through the first coil, the second terminal of the first contact is closed, and both ends of the second terminal are conductive. This causes a contact signal to be transmitted to the external equipment 500 connected to this second terminal.

[0068] When the external equipment 500 receives the contact signal, it performs a predetermined process. This predetermined process includes, for example, sound output, light emission, operation, control of other devices, alarm display, or a combination of at least two of these. This allows a worker at the installation site of the external equipment 500 to know that the notification was normally transferred from the smoke alarm panel 200 to the external equipment 500 in response to the occurrence of an alarm.

[0069] In step S21, the transfer unit 211 of the smoke alarm panel 200 transmits the identifier and the test result received from the slave smoke sensor 300 to the monitoring device 100. The receiving unit 112 of the monitoring device 100 receives the identifier and the 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 them in the memory unit 102.

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

[0072] 7, selection area 150b includes a selection button 152. The selection button 152 accepts an operation to select a smoke alarm panel 200. In display area 150c, sensor areas 159 are displayed in the same number as the 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 156-158, such as "Alarm 1"-"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 density area 154 displays the smoke density measured by the dependent smoke sensor 300. The bar graph 155 displays a bar indicating the smoke density. The alarm symbols 156-158, "Alarm 1"-"Alarm 3", are lit when the alarm levels correspond to "Alarm 1"-"Alarm 3", respectively. This lit display refers to a prominent display in a color such as red.

[0074] The test result of the dependent smoke sensor 300A is displayed in the sensor area 159-1 corresponding to the dependent smoke sensor 300A. If the test result of the dependent smoke sensor 300A includes a smoke density of 0.04% / m and alarm information indicating an alarm level of "alarm 1", the smoke density of 0.04% / m is displayed in the smoke density area 154 of the sensor area 159-1. A bar indicating the smoke density of 0.04% / m is displayed in the bar graph 155 of the sensor area 159-1. The alarm symbol 156 of "alarm 1" is displayed in a lit state. The alarm symbol 157 of "alarm 2" and the alarm symbol 158 of "alarm 3" are displayed in an unlit state. This unlit display refers to a display in an unlit color such as gray so as not to stand out. This display allows the operator to confirm that the alarm operation of the alarm level of "alarm 1" was performed normally in the external output test.

[0075] 6, in step S24, the transmission unit 111 of the monitoring device 100 determines whether or not to change the alarm level and perform the next external output test. For example, when an operation is performed by an operator to change the alarm level and instruct to perform the next external output test, the transmission unit 111 determines that the alarm level will be changed and the next external output test will be performed (YES in step S24). In this case, the process returns to the above-mentioned step S12, and the processes from step S12 onward are performed with the changed alarm level as the target alarm level.

[0076] FIG. 11 is a diagram showing 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. While an external output test is being performed at an alarm level of "alarm 1", a notification screen 170A shown in FIG. 11(a) is displayed. The notification screen 170A includes an alarm level of "alarm 1" and a message indicating that an external output test is being performed. The 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 "alarm 2", which is the next highest alarm level after "alarm 1". In this example, the notification screen 170A includes a message inquiring whether to change the alarm level to "alarm 2" and a "yes" button 171. To subsequently start an external output test at an alarm level of "alarm 2", the worker presses the "yes" button 171.

[0077] In response to this operation, a test start command including an alarm level of "alarm 2" is transmitted from the monitoring device 100 to the dependent smoke sensor 300A via the smoke alarm panel 200. Upon receiving the test start command, the dependent smoke sensor 300A continues the test mode and executes a test at the alarm level of "alarm 2". Here, it is assumed that the threshold value of the alarm level of "alarm 2" is 0.06% / m. In this case, the smoke concentration stored in the memory unit 302 is rewritten to 0.06% / m. Then, without performing an accumulation operation, it is determined that the alarm levels of "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 of "alarm 1" and "alarm 2" 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 in the same manner as in the example shown in FIG. 9. 4, an alarm level "alarm 2" is assigned to the second contact, so in addition to the first contact that has already been activated, the second relay including the second contact is activated and a contact signal is sent to the external equipment 500 connected to the second contact. Furthermore, this test result is sent from the smoke alarm panel 200 to the monitoring device 100. The monitoring device 100 stores this test result in the memory unit 102 and displays it on the display unit 105 in the same manner as the example shown in FIG.

[0078] While the external output test is being performed at the alarm level "alarm 2", the display unit 105 of the monitoring device 100 displays a notification screen 170B shown in FIG. 11(b). The notification screen 170B includes the alarm level "alarm 2" and a message indicating that the external output test is being performed. 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 an external output test at "alarm 3", which is the next highest alarm level after "alarm 2". In this example, the notification screen 170B includes a message inquiring whether to change the alarm level to "alarm 3" and a "yes" button 172. To subsequently perform an external output test at the alarm level "alarm 3", the worker presses the "yes" button 172.

[0079] In response to this operation, a test start command including an alarm level of "alarm 3" is transmitted from the monitoring device 100 to the dependent smoke sensor 300A via the smoke alarm panel 200. Upon receiving the test start command, the dependent smoke sensor 300A continues the test mode and executes a test at the alarm level of "alarm 3". Here, it is assumed that the threshold value of the alarm level of "alarm 3" is 0.08% / m. In this case, the smoke concentration stored in the memory unit 302 is rewritten to 0.08% / m. Then, without performing an accumulation operation, it is determined that the alarm level corresponds to "alarm 1" to "alarm 3". Then, the test result including the smoke concentration of 0.08% / m and alarm information indicating the alarm levels of "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 in the same manner as the example shown in FIG. 9. 4, an alarm level "alarm 3" is assigned to the third contact, so in addition to the first and second contacts that have already been activated, a third relay including the third contact is activated, and a contact signal is transmitted to the external equipment 500 connected to the third contact. Furthermore, 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 memory unit 102, and displays it on the display unit 105 in the same manner as the example shown in FIG.

[0080] 6, if the operator performs an operation to instruct the end of the external output test in step S24 described above, the transmission unit 111 determines that the next external output test is not to be performed (NO in step S24). 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 a notification screen 170C shown in FIG. 11(c). The notification screen 170C includes the alarm level of "alarm 3" and a message indicating that an external output test is being performed. The notification screen 170C also accepts an operation to instruct the end of the external output test. In this example, the notification screen 170C includes an "end test" button 173. To end the external output test, the operator presses the "end test" button 173. When the "end test" button 173 is pressed, it is determined that the next external output test will not be performed.

[0082] Returning to Fig. 6, in step S25, the transmission unit 111 of the monitoring device 100 transmits to the smoke alarm panel 200 to which the dependent smoke sensor 300 to be subjected to the external output test is connected an identifier of the dependent smoke sensor 300 to be subjected to the external output test, and a test end command for instructing the end of the external output test at the target alarm level. For example, the monitoring device 100 transmits the identifier of the dependent smoke sensor 300A and the test end command 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 end command from the monitoring device 100.

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

[0084] Furthermore, when a test end command for the external output test is received, the indicator light 251 of the "Test" button and the indicator light 252 "Caution Switch" shown in Fig. 9 are turned off on the panel surface 250 of the smoke alarm panel 200. Additionally, the first to third contacts are deactivated, and the transmission of contact signals to the external equipment 500 is stopped.

[0085] In step S27, when the dependent smoke sensor 300 receives the test end command, it returns from the external output test mode to the normal alarm mode. This resumes the normal alarm operation. In the normal alarm mode, the smoke detection unit 304 measures the smoke concentration at a predetermined time interval, and the smoke concentration is stored in the memory unit 302. Then, it is determined whether the smoke concentration corresponds to at least one of the alarm levels "alarm 1" to "alarm 3" according to the smoke concentration stored in the memory unit 302. Then, the smoke detection result including the smoke concentration stored in the memory 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 the 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 above-mentioned embodiment, since the accumulation operation is not performed in the dependent smoke sensor 300 in the external output test, the time required for the external output test is shortened. In particular, when the external output tests at a plurality of alarm levels, "alarm 1" to "alarm 3", are performed in sequence, the accumulation operation is omitted in each of the external output tests at these alarm levels, so the time from the start of the external output test at the alarm level "alarm 1" to the end of the external output test at the alarm level "alarm 3" is significantly shortened. In addition, in the above-mentioned embodiment, the accumulation time itself set in the dependent smoke sensor 300 is not changed during the external output test. If the accumulation time set in the dependent smoke sensor 300 is changed to 0 when the external output test is performed, for example, if an operator forgets to return the accumulation time to the original time after the external output test, the accumulation operation will not be performed during the fire test. However, in the above-mentioned embodiment, since the accumulation time itself set in the dependent smoke sensor 300 is not changed during the external output test, the accumulation operation will be performed during the fire test even if the operator does not perform the operation to return the accumulation time. Therefore, it is possible to prevent the accumulation operation from not being performed in 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 an external output test, an operator can instruct the execution of an external output test by operating the monitoring device 100.

[0087] Furthermore, because the external output test is performed separately for the alarm levels "alarm 1" to "alarm 3", it is possible to individually check whether the first to third contacts to which the alarm levels "alarm 1" to "alarm 3" are assigned are operating normally. For example, if the alarm levels "alarm 1" to "alarm 3" are assigned to the first to third contacts, when the external output test is performed at the alarm level "alarm 3", it is determined that all the alarm levels "alarm 1" to "alarm 3" are met, and a contact signal is 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 signal to the external equipment 500 was triggered by reaching the alarm level "alarm 1", the alarm level "alarm 2", or the alarm level "alarm 3". However, by performing external output tests separately for the alarm levels "Alarm 1" to "Alarm 3," it is possible to individually check whether a contact signal was normally output to the external equipment 500 when each of the alarm levels "Alarm 1" to "Alarm 3" was reached.

[0088] Variations The present invention is not limited to the above-described embodiment. The above-described embodiment may be modified as in the following modified examples. The embodiment and the modified examples may be used in combination, or may be switched depending on the implementation. Similarly, the following modified examples may be used in combination, or may be switched depending on the implementation. Variation 1

[0089] In the above-described embodiment, the smoke monitoring system 10 may include one or more stand-alone smoke sensors 400 that transmit and output a signal to an external device 500. The stand-alone smoke sensor 400 is connected to the monitoring device 100 via a first signal line 11. The stand-alone smoke sensor 400 is also connected to the external device 500 via a fourth signal line.

[0090] The independent smoke sensor 400 is also called a stand-alone type smoke sensor, and is a smoke sensor that operates independently without the need for the smoke alarm panel 200. Here, "operates independently" means that the smoke alarm function can be realized without relying on other devices. The independent smoke sensor 400 detects smoke in the surrounding area and outputs an alarm according to the smoke detection result. The independent smoke sensor 400 also performs a test according to the instruction of the monitoring device 100.

[0091] 12 is a diagram showing an example of the configuration of a stand-alone smoke sensor 400. The stand-alone smoke sensor 400 includes 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 reporting circuit 407. The individual units of the stand-alone smoke sensor 400 are connected via a bus.

[0092] The control unit 401, the storage unit 402, the communication unit 403, the smoke detection unit 404, the operation unit 405, the display unit 406, and the report transmission circuit 407 are basically the same as the control unit 101, the storage unit 102, the communication unit 103, the smoke detection unit 304 of the dependent smoke sensor 300, the operation unit 205, the display unit 206, and the report transmission circuit 207 of the smoke alarm panel 200, respectively, of the monitoring device 100. The report transmission circuit 407 is an example of the "output unit" according to the present invention. However, in addition to a program for realizing the function of the independent smoke sensor 400, the storage unit 402 stores a preset accumulation time for the independent smoke sensor 400 and a report transmission database 421 similar to the report transmission database 221 shown in FIG. 4. The concentration of smoke measured by the smoke detection unit 404 is 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 report transfer control unit 416. These functions are realized by the control unit 401 executing a program stored in the storage unit 402, and the control unit 401 performing calculations or controlling each unit of the stand-alone smoke sensor 400.

[0094] The acquisition unit 411, the test unit 412, the determination unit 413, the transmission unit 414, the display control unit 415, and the report transfer control unit 416 are basically similar to the acquisition unit 311, the test unit 312, the determination unit 313, the transmission unit 314, the display control unit 213, and the report transfer control unit 214 of the dependent smoke sensor 300, 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 result of the test to the monitoring device 100.

[0095] As a first operation example according to this modified example, the monitoring device 100 issues an instruction to execute an external output test to the independent smoke sensor 400. Here, it is assumed that the independent smoke sensor 400 includes the independent smoke sensor 400A. For example, when an external output test is to be executed on the independent smoke sensor 400A at an alarm level of "alarm 1", an operator uses the "test" button 151 on the monitoring screen 150 shown in Fig. 7 to select the independent smoke sensor 400A and execute an operation to instruct execution of an external output test at an alarm level of "alarm 1".

[0096] In response to this operation, a test start command including an alarm level of "alarm 1" is transmitted from the monitoring device 100 to the independent smoke sensor 400A. Upon receiving the test start command, the independent smoke sensor 400A transitions to a test mode and executes a test at the alarm level of "alarm 1" without performing an accumulation operation. If the test determines that the alarm level of "alarm 1" is met, the connection state of the contact of the reporting circuit 407 to which that alarm level is assigned is switched, and a contact signal is transmitted to the external equipment 500 connected to that contact. In addition, the test result is transmitted from the independent smoke sensor 400A to the monitoring device 100. The monitoring device 100 stores the test result in the memory unit 102 and displays it on the display unit 105 in the same manner as in the example shown in FIG. 7.

[0097] As a second operation example according to this modified example, an instruction to execute an external output test is given using the operation unit 405 of the stand-alone smoke sensor 400, without using the monitoring device 100. For example, when an external output test at an alarm level of "alarm 1" is to be performed on the stand-alone smoke sensor 400A, an operator uses the operation unit 405 of the stand-alone smoke sensor 400A to give an instruction to execute 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 independent smoke sensor 400A. When the test start command is input, the independent smoke sensor 400A transitions to a test mode and executes a test at the alarm level "alarm 1" without performing an accumulation operation. If the test determines that the alarm level "alarm 1" is met, the connection state of the contact of the reporting circuit 407 to which that alarm level is assigned is switched, and a contact signal is transmitted to the external equipment 500 connected to that contact. The test result is also displayed on the display unit 406.

[0099] According to this modification, since no accumulation operation is performed even in the external output test from the stand-alone smoke sensor 400 to the external equipment 500, the time required for this external output test is shortened.

[0100] Variation 2 In the above-mentioned embodiment or modified example, the accumulation time used in the external output test does not necessarily have to be 0. For example, an accumulation time shorter than the accumulation time used in the fire test may be used in the external output test. For example, if the accumulation time set for the dependent smoke sensor 300 or the independent smoke sensor 400 is 20 seconds, the accumulation operation may be performed in the external output test using a time that is a predetermined time less than this accumulation time, for example, 5 seconds. This modified example also shortens the time required for the external output test.

[0101] Variation 3 In the above-described embodiment or modification, 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 an operator. 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 a destination device via the fifth signal line, the monitoring device 100 exchanges various data with the destination device via the fifth signal line.

[0102] Variation 4 In the above-described embodiment or modified example, the contact included in the report transfer circuit 207 or 407 may be a c-contact, an a-contact, or a b-contact. The relay may be a contact relay or a contactless relay. Furthermore, the number of contacts included in the report transfer circuit 207 or 407 may be less than three, or more than three. Furthermore, all of the alarm levels "Alarm 1" to "Alarm 3" do not have to be assigned to contacts. Only one or two of the multiple alarm levels "Alarm 1" to "Alarm 3" may be assigned to contacts.

[0103] Variation 5 In the above-described embodiment or modification, a plurality of external equipment 500 may be provided. In this case, at least one of the plurality of contacts included in the report circuit 207 or 407 may be connected to an external equipment 500 different from the other contacts, or the plurality of contacts may be connected to different external equipment 500. In addition, the contacts and the external equipment 500 may be connected by wire or wirelessly.

[0104] Variation 6 In the above-described embodiment or modification, if the smoke concentration is equal to or greater than the threshold for the alarm level "Alarm 2", it may not necessarily correspond to the alarm level "Alarm 1". For example, if the smoke concentration is equal to or greater than the threshold for the alarm level "Alarm 2", it may be determined that only the alarm level "Alarm 2" applies. Similarly, if the smoke concentration is equal to or greater than the threshold for the alarm level "Alarm 3", it may not necessarily correspond to the alarm levels "Alarm 1" and "Alarm 2". If the smoke concentration is equal to or greater than the threshold for the alarm level "Alarm 3", it may be determined that only the alarm level "Alarm 3" applies.

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

[0106] Variation 8 In the above-described embodiment or variant, in addition to or instead of the monitoring device 100, the smoke alarm panel 200 may accept an operation to instruct the execution of an external output test, and in response to this operation, send a test start command to the slave smoke sensor 300.

[0107] Variation 9 In the above-mentioned embodiment or modification, the configuration of the various screens displayed on the monitoring device 100 and the panel surface 250 of the smoke alarm panel 200 is not limited to the above-mentioned example. The monitoring screen 150 and the panel surface 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 transition. In addition, the monitoring screen 150 may have any configuration as long as it accepts an operation to instruct the execution of an external output test. For example, the monitoring screen 150 may be configured to include an operation image different from the operation image described in the above-mentioned embodiment, or may be configured to not include some operation images.

[0108] Variation 10 In the above-mentioned embodiment or modified example, the configuration of the smoke monitoring system 10 is not limited to the above-mentioned example. The smoke monitoring system 10 may be configured to include one or more of the above-mentioned devices, or may be configured to not include 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. In addition, the entity having the function of the smoke monitoring system 10 is not limited to the above-mentioned example.

[0109] Variation 11 In the above-described embodiment or modified example, the operation of the smoke monitoring system 10 is not limited to the above-described example. The order of the processing steps of the smoke monitoring system 10 may be changed as long as there is no contradiction. In addition, some of the processing steps of the smoke monitoring system 10 may be omitted.

[0110] Variation 12 Another aspect of the present invention may provide a method having processing steps performed in at least one of the smoke monitoring system 10, the monitoring device 100, the smoke alarm panel 200, the dependent smoke sensor 300, and the independent smoke sensor 400.
