Description

[Technical Field]

[0001] The present disclosure relates to a fire alarm system including a fire receiver and a plurality of fire detectors, and more particularly to a fire alarm system suitable for testing the operation of fire detectors. [Background technology]

[0002] In periodic inspections of automatic fire alarm systems, fire drills, etc., performance is confirmed by conducting operation tests of fire detectors by activating them using smoke and heat testers, etc. A system has been proposed that enables such operations to be carried out efficiently when conducting operation tests of fire detectors (see, for example, Patent Document 1).

[0003] In Patent Document 1, an inspector uses a mobile terminal to select a fire detector for an operation test, and the results of the operation test performed using a test jig are transmitted to the mobile terminal. As a result, Patent Document 1 eliminates the need for an inspector to be present on the server and receiver side, and detector alarm testing can be efficiently carried out with just one inspector who performs the operation test using the test jig. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2018-112951 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the conventional techniques have the following problems. The system disclosed in Patent Document 1 requires a configuration in which fire detectors, receivers, and a server are connected via a network. Furthermore, an inspector must use a mobile terminal with dedicated software installed to select the fire detectors to be tested, conduct the test, and receive the test report results from the server.

[0006] Therefore, although an operational test can be performed by a single inspector, the system configuration is complex.

[0007] Furthermore, in Patent Document 1, when actually conducting an operation test using a test jig, it is not possible to confirm whether the fire detector selected using a mobile terminal matches the fire detector for which the operation test should actually be conducted. As a result, there is a risk that an operation test will be conducted on a fire detector different from the selected fire detector, which may not necessarily improve work efficiency.

[0008] The present disclosure has been made to solve the above-mentioned problems, and aims to provide a fire alarm system that is configured to include a fire receiver and multiple fire detectors and that can efficiently perform operation tests on selected fire detectors. [Means for solving the problem]

[0009] The fire alarm system according to the present disclosure is a fire alarm system provided in a fire monitoring area, and including a plurality of fire detectors that detect the occurrence of a fire, and a fire receiver that issues a fire alarm based on the respective detection results of the plurality of fire detectors, wherein the fire receiver has a mode setting function that controls switching between a fire monitoring mode that monitors fires and an operation test mode that tests the operation of the plurality of fire detectors, and a first selection function that, when conducting an operation test in the operation test mode, enables selection of one or more fire detectors to be the object of operation test from among the plurality of fire detectors, and transmits an operation test object signal to the one or more fire detectors selected as the object of operation test, indicating that the fire detector is the object of operation test, and each of the plurality of fire detectors has an identification display function that, when receiving the operation test object signal from the fire receiver, displays an identification display on a display provided on the detector body to indicate that the fire detector is the object of operation test. When the fire receiver receives a detection result from a fire detector that has not been selected as a target for operation testing, it determines that an erroneous operation has occurred and transmits an erroneous operation signal to the fire detector that has been determined to have been erroneously operated, indicating that the fire detector is not selected as a target for operation testing. Each of the multiple fire detectors further has an erroneous operation identification display function that, when it receives an erroneous operation signal from the fire receiver, displays an identification display on the detector body indicating that the fire detector is not selected as a target for operation testing. It is something. The fire alarm system according to the present disclosure is a fire alarm system provided in a fire monitoring area, and including a plurality of fire detectors for detecting the occurrence of a fire, and a fire receiver for issuing a fire alarm based on the respective detection results of the plurality of fire detectors, wherein the fire receiver has a mode setting function for controlling switching between a unit test mode for testing the operation of the plurality of fire detectors and an interlocking test mode for testing the operation of the plurality of fire detectors in conjunction with the interlocking operation of the fire detectors and terminal equipment, and in the interlocking test mode, makes it possible to select one terminal equipment to be the subject of the interlocking test from a plurality of terminal equipments that operate in conjunction with the respective detection results of the plurality of fire detectors, and a first extraction function that extracts a fire detector that will be the interlocking source of one terminal equipment selected by the first extraction function; a second selection function that enables selection of one fire detector that will be the interlocking source extracted by the first extraction function and transmits an operation test target signal to the one fire detector selected as the operation test target; and a first interlock operation test function that receives a detection result in the interlock test mode from the one fire detector that has received the operation test target signal, outputs an interlock operation command to cause the one terminal equipment that will be the interlocking test target to perform an interlocking operation, and executes an operation test involving interlocking operation between the one fire detector that will be the interlocking test target and the one terminal equipment that will be the interlocking test target. The fire alarm system according to the present disclosure is a fire alarm system provided in a fire monitoring area, and including a plurality of fire detectors for detecting the occurrence of a fire, and a fire receiver for issuing a fire alarm based on the respective detection results of the plurality of fire detectors, wherein the fire receiver has a mode setting function for controlling switching between a unit test mode for testing the operation of the plurality of fire detectors and an interlocking test mode for testing the operation of the plurality of fire detectors, and a mode setting function for controlling switching between a unit test mode for testing the operation of the fire detectors alone and an interlocking test mode for testing the operation of the fire detectors with interlocking operation between the fire detectors and terminal equipment, and a mode setting function for controlling switching between a unit test mode for testing the operation of ... a second extraction function that extracts terminal equipment to be linked with the fire detector; a third selection function that enables selection of one or more terminal equipment to be the target of the interlocking test from the terminal equipment to be the target of the interlocking test extracted by the second extraction function, and transmits an operation test target signal to the one fire detector selected as the target of the operation test; and a second interlocking operation test function that receives a detection result in the interlocking test mode from one fire detector that has received the operation test target signal, and outputs an interlocking operation command to cause the one or more terminal equipment to perform an interlocking operation, thereby executing an operation test involving interlocking operation between the one fire detector to be the target of the operation test and one or more terminal equipment to be the target of the interlocking test.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, preferred embodiments of the fire alarm system of the present disclosure will be described with reference to the drawings. The fire alarm system according to the present disclosure has a technical feature in that, for a fire detector selected as a target for an operation test, an indicator provided on the detector body displays an identification mark indicating that the detector is a target for an operation test. As a result, an inspector can easily visually confirm the fire detector that is the target for the operation test based on the identification marking and then perform the operation test.

[0013] Embodiment 1 First, the overall system will be described. 1 is a diagram illustrating the overall configuration of a fire alarm system including a fire receiver and a plurality of fire detectors according to a first embodiment of the present disclosure. The fire receiver 10 is connected to an addressable transmitter 20, fire detectors 31 and 32, a detector repeater 40, and a smoke control repeater 50 via a signal line SG.

[0014] A plurality of fire detectors are connected to the detector repeater 40. In Fig. 1, four fire detectors 41 to 44 are shown as an example. In addition, a fire door 51, a smoke exhaust machine 52, a shutter 53, and a hanging wall 54 are connected to the smoke prevention and exhaust control repeater 50.

[0015] Here, the fire detectors 31, 32 and the fire detectors 41 to 44 correspond to a plurality of fire detectors that detect the occurrence of a fire in each of the preset fire monitoring areas. A plurality of fire detectors constitutes a detector group.

[0016] In addition, the fire door 51, the smoke exhauster 52, the shutter 53, and the hanging wall 54 correspond to a plurality of terminal equipment that operate in conjunction with the detection results of the plurality of fire detectors and function to prevent the spread of fire, smoke, etc. A terminal equipment group is made up of a plurality of terminal equipment.

[0017] Address information for identifying each individual fire detector is assigned in advance to each of the multiple fire detectors. Each of the multiple fire detectors can transmit fire-related information including the address information assigned to it to the fire control panel 10. Meanwhile, the fire control panel 10 can transmit required information to a desired fire detector by adding address information to the information.

[0018] Furthermore, each of the multiple terminal devices is assigned address information in advance to identify each terminal device. Therefore, the fire alarm control device 10 can transmit a command to operate the desired terminal device by adding the address information and transmitting the information.

[0019] With this configuration, the fire receiving device 10 collects fire-related information from a plurality of fire detectors installed in various predetermined fire monitoring areas and the addressable transmitter 20. Then, the fire receiving device 10 can issue a fire alarm and activate a group of terminal equipment based on the collected fire-related information.

[0020] It is to be noted that each terminal equipment included in the terminal equipment group is specified in advance as to which fire detector detection result it should operate in conjunction with. For example, by setting in advance the correspondence between the interlocking operations of multiple fire detectors and multiple terminal equipment as an interlocking table, the fire receiving device 10 can identify the appropriate terminal equipment from the interlocking table based on the detection results of each of the multiple fire detectors and perform interlocking operations.

[0021] Also, although not shown in the figure, the fire receiver 10 can output an alarm signal based on the collected fire-related information, activate fire extinguishing equipment to begin fire extinguishing operations, issue a fire alarm or provide evacuation guidance using an emergency broadcast device, and transmit fire-related information to a higher-level device via a network.

[0022] Next, the technical features of the fire alarm system according to the present embodiment 1 will be described. The fire alarm system according to the present embodiment 1 is technically characterized in that the fire receiver has a mode setting function and a first selection function, and each of the plurality of fire detectors has an identification display function. Each function will now be described in detail.

[0023] <About the mode setting function> The fire control panel 10, which centrally controls the detectors and terminal equipment, has a mode setting function that switches between a fire monitoring mode for monitoring fires and an operation test mode for testing the operation of multiple fire detectors. This mode setting function can be realized, for example, by a touch panel provided on the fire control panel 10.

[0024] When using a touch panel, the inspector will switch from fire monitoring mode to operation test mode by operating the touch panel on the fire receiver 10 before conducting an operation test of the fire detector.

[0025] <About the first selection function> During the operation test mode, the fire receiver 10 allows the selection of one or more fire detectors to be the subject of the operation test from among a plurality of fire detectors when conducting an operation test, and further has a first selection function that transmits an operation test subject signal to the one or more fire detectors selected as the subject of the operation test, indicating that they are the subject of the operation test.

[0026] FIG. 2 is a diagram showing an example screen displayed on a touch panel to enable selection of one or more fire detectors to be subjected to an operation test from among a plurality of fire detectors in the first embodiment of the present disclosure.

[0027] Figure 2 illustrates an example in which six fire detectors 31, 32, 41 to 44 are displayed as corresponding windows W11 to W16, corresponding to the configuration in Figure 1. Furthermore, a "Start Unit Test" button for starting a unit test for the fire detector selected as the target for the operation test is displayed as window W31.

[0028] Therefore, the inspector can select the desired fire detector to be subjected to the operation test by performing a touch input on the touch panel, and can start the unit test after the selection.

[0029] 3 is a diagram showing an example of a screen displayed after one fire detector to be subjected to an operation test is selected from among a plurality of fire detectors in the first embodiment of the present disclosure. In FIG. 3, the fire detector 41 is selected from the group of detectors, and the selected fire detector 41 is highlighted. After such a selection operation, if the "Start Unit Test" button is pressed, the fire control panel 10 transmits an operation test target signal including address information of the fire detector 41 via the signal line SG.

[0030] <About the identification display function> Each of the plurality of fire detectors has an identification display function that, when receiving an operation test target signal from the fire receiver 10, displays an identification display indicating that the fire detector is a target for operation test.

[0031] For example, when a fire detector 41 transmits an operation test target signal including its own address information, it uses a display provided on the detector body to display an identification indication that the detector is a target for operation test using a predetermined lighting pattern, lighting color, etc. Therefore, an inspector can easily visually identify which fire detector is a target for operation test at the fire detector installation site. The display may be a fire confirmation light that lights up when the fire detector detects a fire.

[0032] When the operation test mode is set, the fire receiver 10 only allows the operation test of the fire detector alone and can prohibit linked operation that activates related terminal equipment based on the detection result. In other words, when the fire receiver 10 receives a detection result from the fire detector that transmitted the operation test target signal, it performs control not to perform linked operation. It also performs control not to output an alarm signal to fire extinguishing equipment or emergency broadcast equipment.

[0033] As described above, according to the first embodiment, a fire detector selected as a target for an operation test can be marked with an identification mark indicating that the fire detector is a target for an operation test. As a result, an inspector can easily visually confirm the fire detector that is a target for an operation test based on the identification marking result and then perform the operation test, thereby improving work efficiency.

[0034] Although FIG. 3 illustrates a case where one fire detector is selected as the target for the operation test, it is also possible to select two or more fire detectors as the target for the operation test.

[0035] Embodiment 2 In the first embodiment, we have explained how to improve work efficiency when conducting an operation test of a single fire detector. In contrast, in the second embodiment, we will explain how to improve work efficiency when conducting an interlocking operation test that utilizes the identification display function and interlocks terminal equipment based on the detection result of the fire detector.

[0036] The fire alarm system according to the second embodiment is characterized in that the fire alarm receiver further has a first extraction function, a second selection function, and a first interlocking operation test function, and also has a mode setting function that allows switching between a standalone test mode and an interlocking test mode. Each function will now be described in detail.

[0037] <Improvements to the mode setting function> In the second embodiment, it is possible to perform an interlocking operation test that interlocks terminal equipment based on the detection result of a fire detector. Therefore, when the operation test mode is selected in the mode setting function, the fire receiving device 10 according to the second embodiment further performs setting switching control between a unit test mode that performs an operation test of the fire detector alone and an interlocking test mode that performs an operation test involving interlocking operation between the fire detector and terminal equipment.

[0038] Therefore, before conducting an operation test of a fire detector, an inspector can easily switch the settings by operating the touch panel provided on the fire receiver 10 to either conduct an operation test of the fire detector alone or conduct an operation test involving the linked operation of the fire detector and terminal equipment.

[0039] <About the first extraction function> When the interlocking test mode is selected, the fire receiver 10 allows selection of one terminal equipment to be the subject of the interlocking test from among a plurality of terminal equipment that operate in conjunction with the respective detection results of a plurality of fire detectors, and has a first extraction function that extracts the fire detector that is the source of the interlocking test of the one terminal equipment selected as the subject of the interlocking test.

[0040] <About the second selection function> When performing an operation test involving the operation of a fire detector linked to a terminal device during the linked test mode, the fire receiver 10 has a second selection function that enables selection of one fire detector to be the subject of the operation test from among the fire detectors that are the source of the link extracted by the extraction function, and transmits an operation test subject signal to the one fire detector selected as the subject of the operation test.

[0041] Fig. 4 is a diagram showing an example of a screen displayed on a touch panel when an interlocking test mode is selected in the second embodiment of the present disclosure. Fig. 4 illustrates a case in which, corresponding to the configuration of Fig. 1, six fire detectors 31, 32, and 41-44 are displayed as corresponding windows W11-W16, and four terminal equipment, fire door 51, smoke exhauster 52, shutter 53, and drop wall 54, are displayed as corresponding windows W21-W24.

[0042] Furthermore, in Figure 4, a "Start Interlocking Test" button is displayed as window W32 to start an interlocking test between the terminal equipment selected as the interlocking test target and the fire detector selected as the operation test target, which is the source of the interlocking.

[0043] Note that windows W11 to W16 are provided with sub-windows W111 to W116, respectively, and windows W21 to W24 are provided with sub-windows W121 to W124, respectively. The role of the sub-windows will be described later with reference to Figures 5A and 5B.

[0044] By touching the screen on the touch panel shown in Figure 4, the inspector can select the desired fire detector to be tested for operation and the terminal equipment to be tested for interlocking, and can then start the interlocking test after making the selection.

[0045] 5A is a diagram showing an example of a screen after one terminal equipment to be a target for an interlocking test is selected from a plurality of terminal equipment in the second embodiment of the present disclosure. In the second embodiment, when interlocking operation between a fire detector and a terminal equipment is performed, the terminal equipment to be interlocked is first selected.

[0046] In Figure 5A, when "fire door 51" is selected from the group of terminal equipment, "fire door 51" is displayed in reverse and the state in which the sources of linkage of "fire door 51" are "fire detector 31" and "fire detector 41" is illustrated.

[0047] Specifically, the fire receiver 10 refers to an interlocking table in which the correspondence between the interlocking operations of multiple fire detectors and multiple terminal equipment is preset, and when it determines that the interlocking source of the "fire door 51" is the "fire detector 31" and the "fire detector 41," it displays the sub-window W111 corresponding to the "fire detector 31" and the sub-window W113 corresponding to the "fire detector 41" in an identifiable manner.

[0048] Therefore, the inspector can easily determine which fire detector is the source of the linkage of the selected "fire door 51" by visually checking the identification marking on the touch panel, without having to check the linkage table.

[0049] 5B is a diagram showing an example of a screen in which one terminal equipment to be the subject of an interlocking test has been selected, and then one fire detector as the interlocking source has been selected, in Embodiment 2 of the present disclosure. Specifically, FIG. 5B shows an example of a screen in which "fire door 51" has been selected as one terminal equipment to be the subject of an interlocking test, and then "fire detector 41" has been selected from "fire detector 31" and "fire detector 41" as the interlocking source, thereby highlighting "fire detector 41."

[0050] Specifically, the inspector identifies that "fire detector 31" whose sub-window W111 is illuminated and "fire detector 41" whose sub-window W113 is illuminated are the fire detectors that will be interlocked with "fire door 51." After that, the inspector can select "fire detector 41" as the desired target for the operation test, and after selection, can start the interlock test by pressing the "start interlock test" button.

[0051] When such a series of selection operations and start operations are performed, the fire control panel 10 transmits an operation test target signal including address information of the fire detector 41 via the signal line SG. On the other hand, when the fire detector 41 receives the operation test target signal from the fire control panel 10, the fire detector 41 displays an identification display on the display provided on the detector body to indicate that the detector is the target of an operation test, and executes the identification display function.

[0052] <Regarding the first interlocking operation test function> During the interlocking test mode, the fire receiver 10 has an interlocking operation test function that receives detection results from the fire detector 41 that has received the operation test target signal, and outputs an interlocking operation command to perform an interlocking operation on the fire door 51, which is one of the terminal equipment that is the target of the interlocking test.

[0053] As a result, the fire control receiver 10 can execute an operation test involving interlocking operation between one fire detector to be tested and one terminal equipment to be tested based on the selection result by the inspector. In other words, even if there is terminal equipment other than the fire door 51 that is to be interlocked with the fire detector 41, the fire control receiver 10 can interlock only the fire door 51 and execute a one-to-one interlocking test between the fire detector 41 and the fire door 51.

[0054] As described above, according to the second embodiment, a fire detector selected as a target for an operation test can be provided with an identification mark indicating that the fire detector is a target for an operation test, similar to the first embodiment.

[0055] Furthermore, according to embodiment 2, an interlocking test between the terminal equipment selected as the interlocking test target and the fire detector selected as the interlocking source operation test target can be easily performed by selecting and starting operations using the touch panel, without checking the interlocking table.

[0056] Embodiment 3 In the previous embodiment 2, a method for improving work efficiency when an operation test is performed on a single fire detector was described. In contrast, in this embodiment 3, an improvement method different from that in the previous embodiment 2 will be described for improving work efficiency when an interlocking operation test is performed in which terminal equipment is interlocked based on the detection result of a fire detector, while utilizing the identification display function.

[0057] The fire alarm system according to the third embodiment is characterized in that the fire alarm receiver further has a second extraction function, a third selection function, and a second interlocking operation test function, and also has a mode setting function that allows switching between a standalone test mode and an interlocking test mode. Each function will now be described in detail.

[0058] In the second embodiment, when an interlocking test is performed, a terminal device is selected and then a fire detector that will be the interlocking source is selected. In contrast, in the third embodiment, when an interlocking test is performed, a fire detector is selected and then a terminal device that will be the interlocking destination is selected, which is a different selection order.

[0059] <Improvements to the mode setting function> In this embodiment 3, similar to the previous embodiment 2, it is possible to carry out an interlocking operation test that interlocks terminal equipment based on the detection result of a fire detector. Therefore, similar to the previous embodiment 2, when the operation test mode is selected in the mode setting function, the fire receiving device 10 according to this embodiment 3 further performs setting switching control between a unit test mode that performs an operation test of the fire detector alone and an interlocking test mode that performs an operation test involving interlocking operation between the fire detector and terminal equipment.

[0060] Therefore, before conducting an operation test of a fire detector, an inspector can easily switch the settings by operating the touch panel provided on the fire receiver 10 to either conduct an operation test of the fire detector alone or conduct an operation test involving the linked operation of the fire detector and terminal equipment.

[0061] <About the second extraction function> When the interlocking test mode is selected, the fire receiver 10 allows the selection of one fire detector from among multiple fire detectors to be the subject of an operation test as the source of the interlocking, and has a second extraction function that extracts the terminal equipment to be interlocked with the one fire detector selected as the subject of the operation test.

[0062] <About the third selection function> When performing an operation test involving the operation of a fire detector and a terminal device during the interlocking test mode, the fire receiver 10 has a third selection function that allows selection of one terminal device to be the subject of the interlocking test from the terminal devices to be linked that are extracted by the extraction function, and transmits an operation test subject signal to the one fire detector selected as the subject of the operation test.

[0063] By performing touch input on the screen on the touch panel shown in Figure 4 described in the previous embodiment 2, the inspector can select the desired fire detector to be subjected to the operation test and the terminal equipment to be subjected to the interlocking test, and can start the interlocking test after making the selection.

[0064] 6A is a diagram showing an example of a screen after one fire detector to be the interlocking source and the target of an operation test is selected from among a plurality of fire detectors in Embodiment 3 of the present disclosure. In Embodiment 3, when interlocking operation between a fire detector and a terminal device is performed, the fire detector to be the interlocking source is first selected.

[0065] In Figure 6A, when "fire detector 41" is selected from the group of fire detectors, "fire detector 41" is displayed in reverse and the state in which "fire detector 41" is linked to "fire door 51" and "shutter 53" is illustrated.

[0066] Specifically, the fire receiver 10 refers to an interlocking table in which the correspondence between the interlocking operations of multiple fire detectors and multiple terminal equipment is preset, and when it determines that the interlocking destinations of the "fire detector 41" are the "fire door 51" and the "shutter 53," it displays the sub-window W121 corresponding to the "fire door 51" and the sub-window W123 corresponding to the "shutter 53" in an identifiable manner.

[0067] Therefore, the inspector can easily determine which terminal equipment the selected "fire detector 41" is linked to by visually checking the identification display on the touch panel, without having to check the linkage table.

[0068] 6B is a diagram illustrating an example of a screen in which one terminal equipment is selected from among the linked terminal equipment after one fire detector to be the target of an operation test has been selected in embodiment 3 of the present disclosure. Specifically, FIG. 6B illustrates an example of a screen in which "fire detector 41" is selected as the one fire detector to be the target of an operation test, and then "shutter 53" is selected from among the linked fire doors "fire door 51" and "shutter 53," thereby highlighting "shutter 53."

[0069] Specifically, the inspector identifies that the "fire door 51" whose sub-window W121 is lit and the "shutter 53" whose sub-window W123 is lit are the terminal equipment to be linked with the "fire detector 41." After that, the inspector can select the "shutter 53" as the desired interlocking test target, and after selection, can start the interlocking test by pressing the "start interlocking test" button.

[0070] When such a series of selection operations and start operations are performed, the fire control panel 10 transmits an operation test target signal including address information of the fire detector 41 via the signal line SG. On the other hand, when the fire detector 41 receives the operation test target signal from the fire control panel 10, the fire detector 41 displays an identification display on the display provided on the detector body to indicate that the detector is the target of an operation test, and executes the identification display function.

[0071] <About the second interlocking operation test function> During the interlocking test mode, the fire receiver 10 has an interlocking operation test function that receives detection results from the fire detector 41 that has received the operation test target signal, and outputs an interlocking operation command to perform an interlocking operation on the shutter 53, which is one of the terminal equipment that is the target of the interlocking test.

[0072] As a result, the fire control signal receiver 10 can execute an operation test involving interlocking operation between one fire detector to be the object of the operation test and one terminal equipment to be the object of the interlocking test, based on the selection result by the inspector. In other words, even if there is terminal equipment other than the shutter 53 that is interlocked with the fire detector 41, the fire control signal receiver 10 can interlock only the shutter 53 and execute a one-to-one interlocking test for the fire detector 41 and the shutter 53.

[0073] As described above, according to the third embodiment, a fire detector selected as a target for an operation test can be provided with an identification mark indicating that the fire detector is a target for an operation test, similar to the first and second embodiments.

[0074] Furthermore, according to this embodiment 3, an interlocking test between a fire detector selected as the target for an operation test and a terminal equipment selected as the target for an interlocking test can be easily performed by selecting and starting using a touch panel, without having to check the interlocking table.

[0075] The screen examples shown in FIGS. 2 to 6B in the first to third embodiments are merely examples, and other screens may be used as long as they can realize the functions of the fire alarm system of the present disclosure.

[0076] In addition, the fire receiver can transmit different signals for the activation test target signal in the individual test mode and the activation test target signal in the linked test mode so that they can be distinguished on the fire detector side. In this case, the fire detector can use different lighting patterns, lighting colors, etc. for the identification marking indicating that the fire detector is a target for activation test in the individual test mode and the identification marking indicating that the fire detector is a target for activation test in the linked test mode.

[0077] As a result, inspectors can easily visually confirm the fire detectors that are the subject of the operation test based on the identification display results, and can easily visually confirm whether an interlocking test will be conducted in which the terminal equipment operates in conjunction with the fire detector, thereby improving the work efficiency of the interlocking test.

[0078] In addition, in the above-mentioned embodiments 2 and 3, we have explained the case where a one-to-one interlocking test is performed between a fire detector and terminal equipment, but it is also possible to perform an interlocking test in a one-to-N (N is an integer greater than or equal to 2) situation where multiple terminal equipment are interlocked with one fire detector.

[0079] Furthermore, in the above-mentioned embodiment 1, when the operation test mode is set, it has been explained that when the operation test mode is set, interlocking control and control not to output an alarm signal are performed. However, it is also possible to set these controls manually, and when the operation test mode is selected and Figure 2 or Figure 3 is displayed, it is also possible to provide a new window with a "All interlocking operations shut off" button for prohibiting all interlocking operations at once, a "All alarm signal shut off" button for prohibiting all alarm signal outputs at once, and a "All shut off" button for prohibiting both interlocking operations and alarm signal outputs at once.

[0080] Each time the inspector touches the "Interlocking Operation All-Out Cutoff" button, "Reporting Signal All-Out Cutoff" button, or "All-Out Cutoff" button, the "Interlocking Operation All-Out Cutoff", "Reporting Signal All-Out Cutoff" and "All-Out Cutoff" buttons alternate between lit and off. This allows the inspector to control whether or not interlocking operations or report signal output will be performed.

[0081] Furthermore, in the above-mentioned second and third embodiments, a case where one-to-one interlocking tests are performed between a fire detector and terminal equipment is described. However, when the interlocking mode is selected and Figures 4 to 6B are displayed, it is also possible to provide a new window with a "Bulk interlocking operation shutdown" button for prohibiting all interlocking operations at once.

[0082] Each time the inspector touches the "Interlocking Operation All Shutdown" button, the "Interlocking Operation All Shutdown" is alternately switched on and off. Even when the interlocking mode is selected, the inspector can prohibit all interlocking operations at once by turning on the "Interlocking Operation All Shutdown" and can perform an operation test on only the selected fire detectors, just like the "unit test mode" described in the first embodiment.

[0083] 2 to 6B in the first to third embodiments, a return button for returning from the operation test mode to the fire monitoring mode can be provided on the screen, although this is not shown. The inspector can return from the operation test mode to the fire monitoring mode by touching this return button.

[0084] Furthermore, when the return button is selected to return to the fire monitoring mode, the fire receiving device 10 can reset all of the states selected in the first to third embodiments. That is, the fire receiving device 10 automatically performs this reset process when returning to the fire monitoring mode, thereby returning to the initial state according to the interlocking table during fire monitoring.

[0085] As a result, even if the fire monitoring mode is returned to without switching the "all-linked operation cutoff," "all-transmission signal cutoff," or "all-linked cutoff" to the off state, it is possible to reliably prevent human error that would otherwise cause the all-linked operation to be cut off when a fire is detected in the fire monitoring mode.

[0086] Furthermore, in the first to third embodiments, the case where various functions are realized using a touch panel provided on the fire receiving device 10 has been described, but the present invention is not limited to such a configuration. The same effect can be achieved even when a configuration is adopted in which the various functions realized on the touch panel in the first to third embodiments are implemented on an integrated control panel or external device that can communicate with the fire receiving device 10. Here, the external device includes a terminal device such as a mobile terminal carried by an inspector.

[0087] In addition, in embodiments 1 to 3, a fire detector selected as a target for an operation test is identified by a display on the detector body to indicate that it is a target for an operation test, but it is possible that an inspector may perform an operation test on a fire detector that does not have an identification mark.

[0088] Even when such an erroneous operation occurs, the fire receiver 10 according to the present disclosure can determine that an erroneous operation has occurred and control the system so that the linked operation according to the linkage table is not performed when the operation test mode is selected and a detection result is received from a fire detector that has not been selected as the target for the operation test.

[0089] Furthermore, if the fire receiver 10 determines that an erroneous operation has occurred, it can use a display provided on the main body of the fire detector that has been erroneously operated to display an identification display indicating that the fire detector has not been selected as a target for an operation test.

[0090] As a result, even if an inspector mistakenly performs an operation test on a fire detector that is not the subject of the operation test, linked operation can be reliably prevented and the inspector can be quickly and visually notified that an incorrect operation has occurred.
