Description

[Technical Field]

[0001] The present invention relates to a disaster prevention system. [Background technology]

[0002] In a test of a fire detector, there is a technique for measuring the time required for the fire detector to operate (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 3268508 Summary of the Invention [Problem to be solved by the invention]

[0004] Some fire detectors have a function that determines that a fire has occurred and issues a fire alarm when the detector detects a fire again after the accumulation recovery period has passed after the first fire detection. When such a function is provided, the test results may require both the time from the start of the fire detector test until the fire detector first detects a fire and the fire determination time until the detector detects a fire again after the accumulation recovery period has passed. However, there was no technology to measure both of these times without manual intervention.

[0005] One of the objects of the present invention is to obtain, without manual work, the first time until the fire detector first detects a fire and the second time until the fire detector detects a fire again after accumulation recovery, based on the time when the fire detector test is started. [Means for solving the problem]

[0006] One aspect of the present invention provides a disaster prevention system comprising a first measuring means for measuring a first time from the start of a fire detector test to the fire detector first detecting a fire, a second measuring means for measuring a second time from the start of the test to the fire detector again detecting the fire after accumulation recovery, and an output means for outputting the first time and the second time.

[0007] The first measuring means may stop measuring the first time if a set time limit for measuring the first time has elapsed without the fire being detected by the fire detector after the test has started. [Effects of the Invention]

[0008] According to the present invention, the first time until the fire detector first detects a fire and the second time until the fire detector again detects a fire after accumulation recovery can be obtained without any manual work, based on the time when the fire detector test is started.

[0010] First embodiment FIG. 1 is a diagram illustrating an example of an outline of a disaster prevention system 10 according to a first embodiment. The disaster prevention system 10 is a system for quickly detecting a fire and minimizing damage caused by the fire. The disaster prevention system 10 is installed, for example, in a tunnel. The disaster prevention system 10 according to the first embodiment has a non-distributed system configuration. The disaster prevention system 10 includes multiple fire detectors 100, a tester 150, a disaster prevention receiving panel 200, and an operation console 300. Note that FIG. 1 mainly illustrates the configuration related to testing the fire detectors 100, and omits other configurations. The multiple fire detectors 100 are installed, for example, at predetermined intervals within a tunnel. The disaster prevention receiving panel 200 and the operation console 300 are installed, for example, in the tunnel's electrical room. The tester 150 is carried by a maintenance worker. The disaster prevention receiving panel 200 and the multiple fire detectors 100 are connected via a signal line 51. The disaster prevention receiving panel 200 and the operation console 300 are connected via a signal line 52.

[0011] The fire detector 100 detects a fire and transmits a fire signal to the disaster prevention receiving panel 200. For example, the fire detector 100 has a light receiving element and detects flames using a detection principle known as the two-wavelength flickering method. However, the method by which the fire detector 100 detects fires is not limited to the two-wavelength flickering method, and other methods may be used. The fire detector 100 has two operation modes: a monitoring mode and a maintenance mode. The monitoring mode is an operation mode for monitoring fires. The maintenance mode is an operation mode for performing maintenance on the fire detector 100. In the maintenance mode, a test is performed to confirm that the fire detector 100 is operating normally.

[0012] The tester 150 is used for testing to confirm the operation of the fire detector 100. The tester 150 is supported by a maintenance person so that it is in contact with the fire detector 100. The tester 150 may be temporarily fixed to the fire detector 100 using fixing means such as rubber or string. The tester 150 has a light-emitting element and irradiates the fire detector 100 with light for irradiation recognition and pseudo-flame light that indicates a pseudo-flame.

[0013] 2 is a diagram showing an example of the configuration of the disaster prevention receiving panel 200. When the disaster prevention receiving panel 200 receives a fire signal from the fire detector 100, it notifies the fire department that a fire has occurred and controls fire extinguishing equipment and water spray equipment. Here, in order to suppress false fire alarms, the disaster prevention receiving panel 200 does not determine that a fire has occurred when it receives the first fire signal from the fire detector 100, but determines that a fire has occurred and notifies the fire department when it receives another fire signal from the fire detector 100 after accumulation recovery. This accumulation recovery means that the state of the fire detector 100 is temporarily reset when the first fire signal is received from the fire detector 100.

[0014] The disaster prevention receiving panel 200 includes a control unit 201, a memory unit 202, a communication unit 203, an operation unit 204, and a display unit 205. The control unit 201, also called a processor, controls each unit of the disaster prevention receiving panel 200 and performs various processes. The control unit 201 includes, for example, a CPU (Central Processing Unit). The memory unit 202, also called a memory, stores various data and programs. The memory unit 202 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 memory unit 202 stores programs for realizing the functions of the disaster prevention receiving panel 200. The communication unit 203 is a communication interface for connecting the disaster prevention receiving panel 200 to signal lines 51 and 52. The communication unit 203 is used to communicate with other devices connected via the signal lines 51 or 52. The operation unit 204 accepts various operations. The operation unit 204 includes, for example, operation buttons. The display unit 205 displays various information. The display unit 205 includes, for example, a liquid crystal display.

[0015] The control unit 201 functions as mode control means 211, first measurement means 212, storage recovery means 213, second measurement means 214, and output means 215. 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 disaster prevention receiving panel 200. Alternatively, the first measurement means 212 and the second measurement means 214 may be realized by a hardware timer.

[0016] The mode control means 211 controls the operation mode of the fire detector 100. The first measurement means 212 measures a warning judgment time when testing the fire detector 100. The warning judgment time is the time from when the test of the fire detector 100 starts until the fire detector 100 first detects a fire. In other words, the warning judgment time indicates the time from when a simulated fire occurs until the fire detector 100 first detects a fire. The warning judgment time is an example of a "first time" according to the present invention. The accumulation recovery means 213 causes the fire detector 100 to perform accumulation recovery when it receives a first fire signal from the fire detector 100. The second measurement means 214 measures a fire judgment time when testing the fire detector 100. The fire judgment time is the time from when the test of the fire detector 100 starts until the fire detector 100 again detects a fire after accumulation recovery. In other words, the fire judgment time indicates the time from when a simulated fire occurs until it is determined that a fire has occurred. The fire judgment time is an example of a "second time" according to the present invention. The output means 215 outputs the advance notice determination time and the fire determination time measured by the first measurement means 212 and the second measurement means 214. The destinations of this output include the memory unit 202 and the display unit 205 or the display unit 302 described later.

[0017] Returning to FIG. 1 , the operation console 300 is used by a maintenance worker to input and output information to and from the disaster prevention receiving panel 200. The operation console 300 includes an operation unit 301 and a display unit 302. The operation unit 301 accepts various operations. The operation unit 301 includes, for example, operation buttons. The display unit 302 displays various information. The display unit 302 includes, for example, a liquid crystal display.

[0018] 3 is a sequence chart showing an example of the operation of the disaster prevention system 10 according to the first embodiment. This operation is started when testing the fire detector 100. In step S11, the mode control means 211 of the disaster prevention receiving panel 200 transmits a maintenance mode signal to the fire detector 100 instructing it to transition to maintenance mode, for example, in response to an operation by a maintenance technician using the operation unit 204 or 301. In step S12, upon receiving the maintenance mode signal from the disaster prevention receiving panel 200, the fire detector 100 transitions its operating mode to the maintenance mode.

[0019] When the operation mode of the fire detector 100 is shifted to the maintenance mode, the maintenance person holds the tester 150 in contact with the fire detector 100. In step S13, the tester 150 starts irradiating the fire detector 100 with light for irradiation recognition and artificial flame light in response to the operation of the maintenance person. When irradiation from the tester 150 starts, testing of the fire detector 100 starts. In step S14, the fire detector 100 detects irradiation from the tester 150 by receiving the light for irradiation recognition irradiated from the tester 150. In step S15, the fire detector 100 transmits an irradiation start signal indicating that irradiation has started to the disaster prevention receiving panel 200. This irradiation start signal indicates that testing of the fire detector 100 has started. In step S16, when the irradiation start signal is received from the fire detector 100, the first measuring means 212 and the second measuring means 214 of the disaster prevention receiving panel 200 start measuring the advance notice determination time and the fire determination time, respectively.

[0020] In step S17, the fire detector 100 detects a simulated fire using the simulated flame emitted from the tester 150 and determines that a fire has occurred. In step S18, the fire detector 100 transmits a fire signal indicating the occurrence of a fire to the disaster prevention receiving panel 200. In step S19, the first measuring means 212 of the disaster prevention receiving panel 200 stops measuring the advance notice determination time when the fire signal is received from the fire detector 100. This measures the advance notice determination time. In step S20, the output means 215 of the disaster prevention receiving panel 200 stores the advance notice determination time measured in step S19 in the memory unit 202 as a measurement result. At this time, the advance notice determination time is stored, for example, in association with a detector ID that uniquely identifies the fire detector 100 being tested.

[0021] In step S21, the accumulation recovery means 213 of the disaster prevention receiving panel 200 transmits an accumulation recovery signal to the fire detector 100 to cause the fire detector 100 to perform accumulation recovery. In step S22, upon receiving the accumulation recovery signal from the disaster prevention receiving panel 200, the fire detector 100 performs accumulation recovery. For example, the fire detector 100 performs accumulation recovery by initializing state information through software processing. This state information includes internal variables such as the A / D values of the sensors, various counter values, and fire determination flags. This accumulation recovery resets the state of the fire detector 100, returning it to the state it was in before the fire was detected.

[0022] In step S23, after the accumulation recovery, the fire detector 100 again detects a pseudo fire by the pseudo flame light irradiated from the tester 150 and determines that a fire has occurred. In step S24, the fire detector 100 transmits a fire signal indicating the occurrence of a fire to the disaster prevention receiving panel 200. In step S25, when the second measuring means 214 of the disaster prevention receiving panel 200 receives the first fire signal from the fire detector 100 after transmitting the accumulation recovery signal in step S21, the second measuring means 214 of the disaster prevention receiving panel 200 ends measurement of the fire determination time. This allows the fire determination time to be measured.

[0023] In step S26, the output means 215 of the disaster prevention receiving panel 200 stores the fire determination time measured in step S25 as a measurement result in the memory unit 202. At this time, the fire determination time is stored in association with, for example, a detector ID that uniquely identifies the fire detector 100 that is the subject of the test. The advance notice determination time and the fire determination time stored in the memory unit 202 are used, for example, to report the test results of the fire detector 100.

[0024] Here, if the fire detector 100 does not operate normally, a fire may not be detected even if a simulated flame is emitted from the tester 150. In this case, in order to stop the measurement of the warning judgment time and the fire judgment time midway, a time limit may be set in advance for the warning judgment time and the fire judgment time. This time limit is set, for example, by a maintenance person operating the operation unit 204 or 301. The initial value of the time limit for the warning judgment time is, for example, 30 seconds. The time limit for the warning judgment time is set, for example, in the range of 1 to 30 seconds. Similarly, a time limit is set for the fire judgment time. The time limit for the warning judgment time may be the same as the time limit for the fire judgment time, or the time limit for the fire judgment time may be longer than the time limit for the warning judgment time.

[0025] If the time limit for the advance notice determination time has elapsed without receiving a fire signal from the fire detector 100, using the time point at which measurement of the advance notice determination time was started in the above-mentioned step S16 as a reference, the first measurement means 212 stops measuring the advance notice determination time, indicating that the fire detector 100 is not operating normally. Similarly, if the time limit for the fire determination time has elapsed without receiving a fire signal from the fire detector 100 after transmitting the accumulation recovery signal in the above-mentioned step S21, using the time point at which measurement of the fire determination time was started in the above-mentioned step S16 as a reference, the second measurement means 214 stops measuring the fire determination time, indicating that the fire detector 100 is not operating normally after accumulation recovery. Note that if measurement of the advance notice determination time or the fire determination time is stopped midway, information indicating that measurement of the advance notice determination time or the fire determination time has been stopped is stored in the memory unit 202.

[0026] 4 is a timing chart showing an example of measurement of the advance notice determination time and the fire determination time. When an irradiation start signal is received from the fire detector 100 at time t1, the first measurement means 212 and the second measurement means 214 start measuring the advance notice determination time T1 and the fire determination time T2, respectively. When a first fire signal is received from the fire detector 100 at time t2, the first measurement means 212 ends measurement of the advance notice determination time T1. This measures the advance notice determination time T1 from time t1 when the irradiation start signal is received to time t2 when the first fire signal is received. After a storage recovery signal is transmitted to the fire detector 100 at time t3, when a fire signal is received from the fire detector 100 at time t4, i.e., when the first fire signal is received from the fire detector 100 after storage recovery, the second measurement means 214 ends measurement of the fire determination time T2. This allows the measurement of a fire determination time T2 from time t1 when the irradiation start signal is received to time t4 when the fire signal is received again after the accumulation is restored.

[0027] 5 is a diagram showing an example of the display of the advance notice judgment time and the fire judgment time. For example, when a maintenance worker performs an operation using the operation unit 204 or 301 to instruct the display of the measurement results of the advance notice judgment time and the fire judgment time, the output means 215 causes the display unit 205 or 302 to display the measurement display screen 320 shown in FIG. 5 based on the measurement results stored in the memory unit 202. This measurement display screen 320 includes the detector ID of each fire detector 100 and the advance notice judgment time and the fire judgment time measured in the test of that fire detector 100. For example, if the advance notice judgment time of "7 seconds" and the fire judgment time of "15 seconds" are measured in the test of the fire detector 100 with the detector ID "001," the advance notice judgment time of "7 seconds" and the fire judgment time of "15 seconds" are displayed in association with the detector ID "001." If the measurement of the warning judgment time or fire judgment time is stopped midway, information indicating that the time measurement has been stopped, such as "***", is displayed instead of the warning judgment time or fire judgment time.

[0028] According to the first embodiment described above, the disaster prevention receiving panel 200 measures the advance notice determination time and the fire determination time, so that the advance notice determination time and the fire determination time can be obtained without manual work.

[0029] Second embodiment FIG. 6 is a diagram illustrating an example of an overview of a disaster prevention system 20 according to the second embodiment. The disaster prevention system 20 according to the second embodiment has a distributed system configuration. The disaster prevention system 20 includes multiple fire detectors 100, a tester 150, multiple relay panels 400, a disaster prevention receiving panel 200, and an operation console 300. Similar to FIG. 1, FIG. 6 mainly illustrates the configuration related to testing the fire detectors 100, and omits other configurations. The multiple relay panels 400 are provided in multiple monitoring ranges obtained by, for example, dividing the area of a tunnel. The disaster prevention receiving panel 200 and each relay panel 400 are connected via a signal line 53. Each relay panel 400 is connected via a signal line 54 to at least one fire detector 100 installed within the same monitoring range.

[0030] In the second embodiment, a relay panel 400 measures the advance notice determination time and the fire determination time instead of the disaster prevention receiving panel 200. The configurations of the fire detector 100, the disaster prevention receiving panel 200, and the operation console 300 of the disaster prevention system 20 according to the second embodiment are basically the same as the configurations of the fire detector 100, the disaster prevention receiving panel 200, and the operation console 300 of the disaster prevention system 10 according to the first embodiment. However, the control unit 201 of the disaster prevention receiving panel 200 does not have to include the first measurement means 212, the accumulation recovery means 213, the second measurement means 214, and the output means 215.

[0031] FIG. 7 is a diagram showing an example of the configuration of the relay panel 400. The relay panel 400 relays signals exchanged between the disaster prevention receiving panel 200 and each fire detector 100. The relay panel 400 includes a control unit 401, a storage unit 402, and a communication unit 403. The control unit 401, the storage unit 402, and the communication unit 403 are similar to the control unit 201, the storage unit 202, and the communication unit 203 of the disaster prevention receiving panel 200 according to the first embodiment, respectively. However, the storage unit 402 stores a program for realizing the functions of the relay panel 400. The communication unit 403 is a communication interface for connecting the relay panel 400 to signal lines 53 and 54. The communication unit 203 is used to communicate with other devices connected via the signal line 53 or 54.

[0032] The control unit 401 functions as a relay means 411, a first measurement means 412, a storage recovery means 413, a second measurement means 414, and an output means 415. These functions are realized by the control unit 401 executing a program stored in the memory unit 402, and the control unit 401 performing calculations or controlling each unit of the relay panel 400. Alternatively, the first measurement means 412 and the second measurement means 414 may be realized by a hardware timer. The relay means 411 relays signals exchanged between the disaster prevention receiving panel 200 and each fire detector 100. The first measurement means 412, the storage recovery means 413, the second measurement means 414, and the output means 415 are similar to the first measurement means 212, the storage recovery means 213, the second measurement means 214, and the output means 215 of the disaster prevention receiving panel 200 according to the first embodiment. However, the output destinations of the output means 215 include the memory unit 402 and the disaster prevention receiving panel 200.

[0033] FIG. 8 is a sequence chart showing an example of the operation of the disaster prevention system 20 according to the second embodiment. The processing of steps S31 to S34 is the same as the processing of steps S11 to S14 according to the first embodiment. However, in step S31, a maintenance mode signal is transmitted from the disaster prevention receiving panel 200 to the fire detector 100 via the relay panel 400. In step S35, the fire detector 100 transmits an irradiation start signal to the relay panel 400 indicating that irradiation has started. This irradiation start signal indicates that a test of the fire detector 100 has started. In step S36, when the irradiation start signal is received from the fire detector 100, the first measuring means 212 and the second measuring means 214 of the relay panel 400 start measuring the advance notice determination time and the fire determination time, respectively.

[0034] The processing of step S37 is the same as the processing of step S17 according to the first embodiment. In step S38, the fire detector 100 transmits a fire signal indicating the occurrence of a fire to the relay panel 400. In step S39, when the fire signal is received from the fire detector 100, the relay means 411 of the relay panel 400 transfers this fire signal to the disaster prevention receiving panel 200. In step S40, when the fire signal is received from the fire detector 100, the first measuring means 412 of the relay panel 400 ends measurement of the advance notice determination time. This allows the advance notice determination time to be measured. Note that the processing of step S39 and the processing of step S40 may be performed in parallel, or the processing of step S40 may be performed before the processing of step S39.

[0035] In step S41, the output means 415 of the relay panel 400 stores the advance notice determination time measured in step S40 in the memory unit 402 as the measurement result. At this time, the advance notice determination time is stored in association with, for example, a detector ID that uniquely identifies the fire detector 100 to be tested. In step S42, the output means 415 of the relay panel 400 transmits the advance notice determination time stored in the memory unit 402 in step S41 to the disaster prevention receiving panel 200. In step S43, the disaster prevention receiving panel 200 stores the advance notice determination time received from the relay panel 400 in the memory unit 202.

[0036] In step S44, the accumulation recovery means 413 of the relay panel 400 transmits an accumulation recovery signal to the fire detector 100 to restore the accumulation of the fire detector 100. The processes of steps S45 and S46 are the same as the processes of steps S22 and S23 according to the first embodiment. In step S47, the fire detector 100 transmits a fire signal indicating the occurrence of a fire to the relay panel 400. In step S48, when the relay means 411 of the relay panel 400 receives a fire signal from the fire detector 100, it transfers this fire signal to the disaster prevention receiving panel 200. In step S49, when the second measurement means 414 of the relay panel 400 receives the first fire signal from the fire detector 100 after transmitting the accumulation recovery signal in step S44, it ends measurement of the fire determination time. This allows the fire determination time to be measured. Note that the processes of steps S48 and S49 may be performed in parallel, or the process of step S49 may be performed before the process of step S48.

[0037] In step S50, the output means 415 of the relay panel 400 stores the fire determination time measured in step S49 in the memory unit 402 as the measurement result. At this time, the fire determination time is stored, for example, in association with a detector ID that uniquely identifies the fire detector 100 being tested. In step S51, the output means 415 of the relay panel 400 transmits the fire determination time stored in the memory unit 402 in step S50 to the disaster prevention receiving panel 200. In step S52, the disaster prevention receiving panel 200 stores the fire determination time received from the relay panel 400 in the memory unit 202. As in the first embodiment, the advance notice determination time and the fire determination time are stored, for example, in association with a detector ID that uniquely identifies the fire detector 100 that was tested.

[0038] Furthermore, similar to the first embodiment, time limits may be set in advance for the advance notice determination time and the fire determination time. In this case, the disaster prevention receiving panel 200 transmits, for example, a maintenance mode signal along with the time limit for the advance notice determination time and the time limit for the fire determination time to the relay panel 400. The operation when the time limit for the advance notice determination time or the fire determination time has elapsed without a fire signal being received from the fire detector 100 is the same as the operation described in the first embodiment. However, in the second embodiment, this operation is performed by the first measurement means 412 or the second measurement means 414 of the relay panel 400 instead of the first measurement means 212 or the second measurement means 214 of the disaster prevention receiving panel 200.

[0039] The timing of measuring the advance notice determination time and the fire determination time is also the same as in the first embodiment. However, in the second embodiment, the first measurement means 412 and the second measurement means 414 of the relay panel 400 measure the advance notice determination time and the fire determination time instead of the first measurement means 212 and the second measurement means 214 of the disaster prevention receiving panel 200.

[0040] According to the second embodiment described above, the advance notice determination time and the fire determination time are measured by the relay panel 400, so that the advance notice determination time and the fire determination time can be obtained without manual work.

[0041] Variations The present invention is not limited to the above-described embodiments. The above-described embodiments may be modified as in the following modified examples. The embodiments and 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.

[0042] In each of the above-described embodiments, the fire detector 100 may measure the advance notice determination time and the fire determination time instead of the disaster prevention receiving panel 200 or the relay panel 400. In this case, the fire detector 100 measures the time from when the tester 150 starts irradiating until a fire is first detected or determined as the advance notice determination time. The fire detector 100 also measures the time from when the tester 150 starts irradiating until a fire is again detected or determined after accumulation is restored as the fire determination time. The fire detector 100 then transmits the measured advance notice determination time and fire determination time to the disaster prevention receiving panel 200 or the relay panel 400. According to this modification, the advance notice determination time and the fire determination time are measured by the fire detector 100, so that the advance notice determination time and the fire determination time can be obtained without manual work.

[0043] In each of the above-described embodiments, when the fire detector 100 includes a fire detection unit including one light receiving element on each side, and the fire detection unit on the right side (hereinafter referred to as the "right eye") and the fire detection unit on the left side (hereinafter referred to as the "left eye") of the fire detector 100 monitor the spaces on the left and right sides of the fire detector 100, respectively, the right eye and the left eye of the fire detector 100 are tested separately. In this case, the advance notice determination time and the fire determination time may be measured for each of the right eye and the left eye tests of the fire detector 100. In this modification, for example, the irradiation start signal indicates that irradiation has started and also indicates whether the target eye of irradiation by the tester 150 is the right eye or the left eye. Furthermore, the advance notice determination time and the fire determination time are stored in association with, for example, the detector ID described above and also with information identifying the eye to be tested by the fire detector 100. Furthermore, the measurement display screen 320 includes the detector ID of each fire detector 100, information identifying the eye being tested, and the advance notice judgment time and fire judgment time measured in the test of the right eye or left eye of that fire detector 100. For example, if an advance notice judgment time of "7 seconds" and a fire judgment time of "15 seconds" are measured in the test of the right eye of a fire detector 100 with a detector ID of "001", the detector ID "001", the "right eye", the advance notice judgment time of "7 seconds", and the fire judgment time of "15 seconds" are stored and displayed in association with each other.

[0044] In each of the above-described embodiments, the output of the advance notice judgment time and the fire judgment time is not limited to being stored in the memory unit 202 or displayed on the display unit 205 or 302. For example, if the operation console 300 includes a printer, the advance notice judgment time and the fire judgment time may be printed by the printer. Also, the advance notice judgment time and the fire judgment time may be transmitted to a remote monitoring device connected to the disaster prevention receiving panel 200 via a signal line. Furthermore, the advance notice judgment time and the fire judgment time may be stored in a storage medium such as a USB (Universal Serial Bus) memory, and read from this storage medium and displayed on a device such as a personal computer installed in a different location.

[0045] In each of the above-described embodiments, the installation location of the disaster prevention system 10 or 20 is not limited to a tunnel. The disaster prevention system 10 or 20 may be installed anywhere where a fire may occur. Furthermore, a fire receiver may be used instead of the disaster prevention receiving panel 200. Furthermore, the method by which the fire detector 100 detects a fire is not limited to a flame type. For example, the method by which the fire detector 100 detects a fire may be a smoke type or a heat type. The tester 150 outputs a pseudo-fire signal according to the fire detection method. For example, if the fire detection method is a smoke type, the tester 150 emits smoke instead of a pseudo-flame. If the fire detection method is a heat type, the tester 150 emits heat instead of a pseudo-flame. In this modification, the test of the fire detector 100 starts when the tester 150 starts outputting smoke or heat.

[0046] In each of the above-described embodiments, the configuration of the disaster prevention system 10 or 20 is not limited to the above-described examples. The disaster prevention system 10 or 20 may be configured to include one or more of the above-described devices, or may be configured without including some of the devices. Furthermore, the entity that performs the functions of the disaster prevention system 10 or 20 is not limited to the above-described examples. For example, the function of the disaster prevention receiving panel 200 may be realized by multiple devices working together. For example, the disaster prevention receiving panel 200 may not have the operation unit 204 and the display unit 205. If the disaster prevention receiving panel 200 does not have the operation unit 204 and the display unit 205, operation and display are performed using the operation unit 301 and the display unit 302 of the operation console 300. Alternatively, the operation console 300 may not be provided. If the operation console 300 is not provided, operation and display are performed using the operation unit 204 and the display unit 205 of the disaster prevention receiving panel 200.

[0047] In each of the above-described embodiments, the operation of the disaster prevention system 10 or 20 is not limited to the above-described examples. The order of the processing steps of the disaster prevention system 10 or 20 may be changed as long as there is no contradiction. Furthermore, some of the processing steps of the disaster prevention system 10 or 20 may be omitted.

[0048] Another aspect of the present invention may provide a method having processing steps performed in the disaster prevention system 10, the disaster prevention receiving panel 200, or the relay panel 400. Furthermore, yet another aspect of the present invention may provide a program executed in the disaster prevention receiving panel 200 or the relay panel 400. This program may be provided by being stored in a computer-readable recording medium, or may be provided by downloading via the Internet or the like. [Explanation of symbols]
