[0006] Generally, the person who sets up the interlocking settings, such as the contractor who installs the fire alarms, is different from the inspector who periodically inspects the fire alarms after installation. The inspector must check the settings made by the contractor before inspecting them, but it is not easy to share the interlocking settings between different contractors. Even if the contractor keeps documents containing the interlocking setting information, the inspector must check the documents for each fire alarm, which places a heavy burden on the inspector in checking the interlocking setting.

The aforementioned When the interlocking simulation mode is set by the mode setting unit, the control unit does not output the interlocking signal to the disaster prevention device when the detector issues an alarm, and causes the interlocking simulation display unit corresponding to the disaster prevention device to display the signal. The interlocking simulation display unit includes a light-emitting element mounted on the circuit board and disposed adjacent to the connection point of the terminal. It is something. Further, the fire receiver according to the present invention is a fire receiver connected to a plurality of sensors and a plurality of disaster prevention devices, and includes an interlocking simulation display unit provided corresponding to each of the plurality of disaster prevention devices and indicating that the disaster prevention device is an interlocking destination, a mode setting unit for setting a monitoring mode or an interlocking simulation mode, a control unit, an interlocking cutoff display unit provided corresponding to each of the plurality of disaster prevention devices and indicating that the disaster prevention device is an interlocking destination, a cutoff setting unit for setting cutoff of the interlock, and a circuit board provided within a housing of the fire receiver and to which a terminal of a signal line that outputs an alarm transfer signal to the disaster prevention device is connected, and when the monitoring mode is set by the mode setting unit, the control unit controls the disaster prevention device when the sensor activates an alarm. and outputs the alarm signal to the disaster prevention device to link the disaster prevention device, and when the mode setting unit has set the interlocking simulation mode, the control unit, when the sensor activates an alarm, does not output the alarm signal to the disaster prevention device and causes the interlocking simulation display unit corresponding to the disaster prevention device to display an indication that the interlocking has been cut off, when the sensor activates an alarm, and when the cut-off setting unit has set the interlocking to be cut off and the mode setting unit has set the cut-off confirmation mode, the control unit, when the sensor activates an alarm, does not output the alarm signal to the disaster prevention device and causes the interlocking cut-off display unit to display an indication that the interlocking has been cut off, and the interlocking cut-off display unit is mounted on the circuit board and includes a light-emitting element located adjacent to the connection point of the terminals.

DETAILED DESCRIPTION OF THE INVENTION
[0011] An embodiment of a fire alarm receiver according to the present invention will be described below with reference to the drawings. The present invention is not limited to the following embodiments and illustrated aspects, and various modifications are possible without departing from the spirit of the present invention. The present invention also includes all possible combinations of the configurations shown in the following embodiments. In addition, in each drawing, identical symbols indicate identical or corresponding parts, and this applies throughout the entire specification. In the following description, terms indicating directions will be used as appropriate to facilitate understanding, but these terms are for explanatory purposes and do not limit the present invention. Examples of directional terms include "up," "down," "right," "left," "front," and "rear."
[0012] Embodiment 1 (Fire alarm system configuration) 1 is a diagram illustrating the configuration of a fire alarm system 100 including a fire receiver 1 according to embodiment 1. The fire alarm system 100 includes the fire receiver 1, a detector 3 and a transmitter 4 connected to the fire receiver 1 via a detector line 2, and a smoke control device 6 and an acoustic device 7 connected to the fire receiver 1 via a transmission line 5. Note that the number of detector lines 2 and transmission lines 5 shown in the figure is an example, and the numbers are not limited to those shown in the figure.
[0013] The detector 3 is, for example, a heat detector, a smoke detector, or a flame detector. When the detector 3 detects a change in a physical phenomenon caused by a fire, it changes the open / close state of the contacts connected to the detector circuit 2, thereby changing the voltage of the detector circuit 2. The fire receiver 1 monitors the voltage of the detector circuit 2, and acquires (receives) the voltage change caused by the detector 3 changing the open / close state of the contacts as a fire alarm signal. Note that in this embodiment, an example will be described in which the fire receiver 1 is a P-type fire receiver that uses a voltage change, which is a signal common to each detector 3, as an alarm signal, but the fire receiver 1 may also be an R-type fire receiver.
[0014] The transmitter 4 is a device that transmits a fire signal to the fire receiver 1 when a person who discovers a fire presses a push button. When the push button is pressed, the voltage of the detector line 2 connected to the fire receiver 1 changes. The fire receiver 1 monitors the voltage of the detector line 2, and acquires (receives) the change in voltage that occurs when the push button is pressed as a fire signal.
[0015] The smoke control and exhaust device 6 is a device that prevents the passage of smoke or exhausts smoke from a building. Specifically, the smoke control and exhaust device 6 is one or more of a fire door, a fire damper, a smoke exhaust device, etc. A fire door is installed, for example, on the wall of a building in which the fire alarm system 100 is installed. It normally allows people to pass through, but closes in the event of a fire to prevent the fire from spreading to other protected compartments. A fire door is also called a fire door, and if it is a shutter type, it is also called a fire shutter. A fire damper is a blade-shaped or plate-shaped door installed inside a duct for air conditioning or ventilation in a building in which the fire alarm system 100 is installed. By closing the duct, it prevents the spread of fire and the escape of hot air in the event of a fire. A fire damper is installed when the duct passes through a fire compartment of a building. A smoke exhaust device has a fan installed in a duct that connects the interior and exterior of a building. The fan rotates to exhaust smoke from the interior to the exterior.
[0016] The sound device 7 notifies the user of the occurrence of a fire by sound or voice when a fire occurs. The sound device 7 is, for example, an emergency bell or a speaker.
[0017] The smoke control device 6 and the sound device 7 are examples of interlocking devices, which are disaster prevention devices that interlock in response to the activation of the detector 3. Examples of interlocking devices that interlock in response to the activation of the detector 3 include, but are not limited to, fire extinguishing equipment such as sprinklers. The term "interlocking device" includes all devices and equipment that interlock in response to the activation of the detector 3.
[0018] (Configuration of fire receiver) The fire receiver 1 includes a control unit 10, a receiving circuit 11, a signal transfer circuit 12, an operation unit 13, a display unit 14, a mode setting unit 15, a linked simulation display unit 16, a linked shutdown display unit 17, and a memory unit 18.
[0019] When an alarm signal from a detector 3 that is a trigger for interlocking is input via the receiving circuit 11, the control unit 10 operates an interlocking device, such as a smoke control device 6 or an audio device 7, via the reporting circuit 12, based on the interlocking settings in the interlocking table 181 stored in the memory unit 18. When a fire is reported by the audio device 7, a person in charge of the fire receiver 1 visually confirms whether or not a fire has occurred. After confirming that a fire has occurred, the person in charge presses the push button on the transmitter 4, and upon receiving the fire signal from the transmitter 4, the fire receiver 1 determines that a fire has occurred. In addition, a determination that a fire has occurred may be made when alarm signals are sent from multiple detectors 3 to one detector line 2.
[0020] Furthermore, if the fire receiver 1 is an R-type fire receiver, the control unit 10 periodically transmits a request signal to the detector 3 requesting the transmission of an analog value. The detector 3 transmits the analog value in response to the request signal. The cycle for requesting the detector 3 for an analog value may differ depending on the type of object the detector 3 is detecting, such as smoke, heat, or flame, or may differ depending on the installation location of the detector 3.
[0021] Furthermore, when the cutoff setting unit 131 of the operation unit 13 has set a cutoff setting for the interlocking device, the control unit 10 does not operate the interlocking device based on the interlocking setting in the interlocking table 181 in accordance with the cutoff setting. The cutoff setting may include a general cutoff that cuts off all interlockings, and a partial cutoff that cuts off only some of the interlockings. When a general cutoff is set, the control unit 10 does not operate any of the interlocking devices. When a partial cutoff is set, the control unit 10 does not operate only the interlocking device that is the target of the cutoff setting, and operates the other interlocking devices.
[0022] The control unit 10 is configured by a dedicated control circuit, a CPU (Central Processing Unit) that executes programs stored in memory, or a combination of these. When the control unit 10 is a CPU, each function executed by the control unit 10 is realized by software, firmware, or a combination of software and firmware.
[0023] The receiving circuit 11 is a circuit to which the sensor line 2, which is connected to the sensor 3 and the transmitter 4, is connected. The receiving circuit 11 receives the alarm signal from the sensor line 2 and the fire signal from the transmitter 4, and sends the received signals to the control unit 10.
[0024] The reporting circuit 12 is a circuit to which the reporting line 5, which is connected to the smoke control device 6 and the sound device 7, is connected. The reporting circuit 12 sends information output from the control unit 10 regarding the detector line 2 on which an alarm signal or fire signal has been generated to the smoke control device 6 and the sound device 7 based on the linkage setting.
[0025] The operation unit 13 includes hardware buttons provided on the housing of the fire receiving device 1. The operation unit 13 may include a touch panel provided over the display of the display unit 14. The operation unit 13 accepts operations from the user and sends a signal corresponding to the operation to the control unit 10.
[0026] The cutoff setting unit 131 is part of the operation unit 13 and performs settings related to the cutoff of interlocking. The cutoff setting unit 131 includes either or both of an input unit for inputting a collective cutoff and an input unit for inputting a partial cutoff. The input unit for partial cutoff may be provided corresponding to each of a plurality of interlocking devices. In addition, the input unit for partial cutoff may be provided corresponding to a group of a portion of a plurality of interlocking devices, in which case the cutoff of interlocking is set on a group-by-group basis for the interlocking devices.
[0027] The display unit 14 displays the sensor line 2 or sensor 3 that generated the alarm signal, and also displays that the transmission signal has been received. The display unit 14 includes light-emitting elements such as LEDs (Light Emitting Diodes) provided on the housing of the fire control panel 1, and a nameplate associated with the light-emitting elements. The display unit 14 may include a liquid crystal display or an organic EL display.
[0028] The mode setting unit 15 sets the operation mode of the fire receiver 1 to the control unit 10. The operation modes include a monitoring mode and an interlocking simulation mode. The operation modes may further include an interruption confirmation mode. The monitoring mode is an operation mode in which fires are monitored on a daily basis, and when the detector 3 activates an alarm, the interlocking device is activated based on the interlocking setting. The interlocking simulation mode is an operation mode in which when the detector 3 activates an alarm, the interlocking simulation display unit 16 displays a display simulating interlocking without activating the interlocking device. The interruption confirmation mode is an operation mode in which when the detector 3 activates an alarm, the interlocking interruption display unit 17 displays an indication of interlocking interruption without activating the interlocking device.
[0029] When the linkage simulation mode is set, the linkage simulation display unit 16 displays a simulation of linkage. The linkage simulation display unit 16 is provided corresponding to each of the multiple disaster prevention devices that are linkage devices. The linkage simulation display unit 16 changes the display based on instructions from the control unit 10 to indicate that the corresponding disaster prevention device is set as the linkage destination for the linkage factor.
[0030] When the cutoff confirmation mode is set, the interlocked cutoff display unit 17 displays the interlocked devices that are set to cut off among the interlocked devices that are set to cut off. The interlocked cutoff display unit 17 is provided corresponding to each of the multiple disaster prevention devices that are interlocked devices. The interlocked cutoff display unit 17 changes the display based on instructions from the control unit 10 to indicate that the corresponding disaster prevention device is set as the cutoff destination.
[0031] The memory unit 18 stores data used for the control of each unit by the control unit 10. The memory unit 18 stores a table that associates each of the sensor lines 2 with information indicating the installation location of that sensor line 2. The memory unit 18 is an internal memory, an external memory medium such as a memory card, or a combination thereof. For example, it is a non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, or EEPROM.
[0032] The interlocking table 181 stored in the memory unit 18 is a table that associates interlocking factors with interlocking devices, which are disaster prevention devices to be interlocked. The interlocking factor is the detector line 2 to which the detector 3 is connected, and the interlocking device is a disaster prevention device such as a smoke control device 6 or an acoustic device 7 connected to the reporting line 5. One or more interlocking devices are set for one or more detector lines 2. The interlocking table 181 is created using a personal computer and dedicated software, and is transferred to and saved in the memory unit 18.
[0033] Fig. 2 is a diagram illustrating the interlocking simulation display unit 16 and the interlocking cutoff display unit 17 according to embodiment 1. In this embodiment, the interlocking simulation display unit 16 and the interlocking cutoff display unit 17 are provided on a circuit board 20, and Fig. 2 shows a schematic front view of the circuit board 20.
[0034] The circuit board 20 is mounted with a detector line terminal block 21 and a report line terminal block 22. The control unit 10 and memory unit 18 shown in FIG. 1 may also be mounted on the circuit board 20. The circuit board 20 is built into the housing of the fire control device 1. The housing of the fire control device 1 is provided with a door for accessing the circuit board 20, and an operator can open the door to view and operate the circuit board 20 and the components mounted thereon. The interlocking simulation display unit 16 and the interlocking interruption display unit 17 are provided near the detector line terminal block 21 and the report line terminal block 22. An operator performing inspection opens the door of the fire control device 1 and operates the circuit board 20 while viewing it. Therefore, by providing the interlocking simulation display unit 16 and the interlocking interruption display unit 17 near the terminal blocks, the operator can easily check the interlocking setting and the interruption setting while performing inspection without the hassle of opening and closing the door.
[0035] The sensor line terminal block 21 is a terminal block to which terminals of the signal lines that make up the sensor line 2 are connected. In this embodiment, the sensor line 2 is configured such that five line lines are provided for one common line, and in Fig. 2, the common line is indicated by Cn (n is a positive integer) and the line line is indicated by Lm (m is a positive integer).
[0036] The report line terminal block 22 is a terminal block to which terminals of the signal lines constituting the report line 5 are connected. Adjacent terminals 221a and 221b form a pair, and one of the pair of signal lines is connected to each of them. A switch (not shown) is provided to switch the connection between terminals 221a and 221b. When this switch connects terminals 221a and 221b, the interlocking device of the report line 5 connected to terminals 221a and 221b operates. When operating in the interlock simulation mode or when the interlocking is set to be cut off, this switch is controlled to the off state, and terminals 221a and 221b are disconnected, thereby preventing the interlocking device from operating. Terminals 222a to 224a and terminals 222b to 224b shown in FIG. 2 have the same configuration as terminals 221a and 221b.
[0037] In this embodiment, the interlocking simulation display unit 16 includes light-emitting elements 161-164 in the same number as the number of interlocking devices connectable to the fire control receiver 1, i.e., the number of report transmission lines 5. In this embodiment, the light-emitting elements 161-164 are provided near each set of terminals 221a and 221b, terminals 222a and 222b, terminals 223a and 223b, and terminals 224a and 224b to which one report transmission line 5 is connected. In other words, the light-emitting elements 161-164 are provided near the connection points of the terminals of the signal lines that make up the report transmission line 5. Here, "nearby" refers to the range in which the plurality of report transmission lines 5 on the circuit board 20 and the plurality of light-emitting elements 161-164 can be recognized in one-to-one correspondence.
[0038] In this embodiment, the interlocking cutoff display unit 17 includes light-emitting elements 171-174 in the same number as the number of interlocking devices connectable to the fire control receiver 1, i.e., the number of report transmission lines 5. In this embodiment, the light-emitting elements 161-164 are provided near each set of terminals 221a and 221b, terminals 222a and 222b, terminals 223a and 223b, and terminals 224a and 224b to which one report transmission line 5 is connected. In other words, the light-emitting elements 171-174 are provided near the connection points of the terminals of the signal lines that make up the report transmission line 5. Here, "nearby" refers to the range in which the plurality of report transmission lines 5 on the circuit board 20 and the plurality of light-emitting elements 171-174 can be recognized in one-to-one correspondence.
[0039] 2 shows an example in which the interlocking simulating display unit 16 and the interlocking cutoff display unit 17 are arranged on the left and right sides of the drawing, sandwiching the terminal block 22 for the reporting line, but the positional relationship between the interlocking simulating display unit 16 and the interlocking cutoff display unit 17 is not limited to the example shown in the figure. The interlocking simulating display unit 16 and the interlocking cutoff display unit 17 may also be arranged adjacent to each other.
[0040] Furthermore, in this embodiment, an example is shown in which the interlocking simulation display unit 16 and the interlocking cutoff display unit 17 are each configured with different light-emitting elements, but the functions of the interlocking simulation display unit 16 and the interlocking cutoff display unit 17 corresponding to one reporting line 5 may be realized by a single light-emitting element. For example, the light-emitting elements 161 and 171 corresponding to terminals 221a and 221b may be configured with a single light-emitting element whose light-emitting color can be changed, and the light-emitting color may be different when displaying a simulated interlocking display and when displaying an interlocking device that is set to cutoff. Instead of changing the light-emitting color of a single light-emitting element, the light-emitting pattern may be different, such as continuous lighting and flashing.
[0041] (Interlocking simulation mode) FIG. 3 is a diagram illustrating the display operation of the interlocking simulation display unit 16 and the interlocking cutoff display unit 17 in the interlocking simulation mode according to the first embodiment. The table at the top of FIG. 3 indicates whether or not interlocking is set for the interlocking devices corresponding to terminals 221a and 221b, terminals 222a and 222b, terminals 223a and 223b, and terminals 224a and 224b, respectively, based on the interlocking table 181 stored in the memory unit 18. Below each column in the table at the top of FIG. 3, the light-emitting states of the corresponding light-emitting elements of the interlocking simulation display unit 16 and the interlocking cutoff display unit 17 are shown changing in the order (A) and (B). The light-emitting elements 161-164 and the light-emitting elements 171-174 are shown in white when they are off and in shaded when they are on.
[0042] FIG. 3(A) shows the initial state of light-emitting elements 161-164 and light-emitting elements 171-174, all of which are off. When an alarm signal from detector 3, which is a factor in interlocking, is input, light-emitting elements 161, 162, and 164 corresponding to terminals 221a and 221b, terminals 222a and 222b, and terminals 224a and 224b, which are set for interlocking, turn on, as shown in FIG. 3(B). At this time, because the interlocking simulation mode is set, the sound device 7 and smoke control device 6, which are interlocking devices, will not operate even if a signal that is a factor in interlocking is input. Furthermore, in the interlocking simulation mode, interlocking shutoff display unit 17 does not change its display.
[0043] (Shutdown confirmation mode) 4 is a diagram illustrating the display operations of the linked simulation display unit 16 and the linked cutoff display unit 17 in the cutoff confirmation mode according to embodiment 1. The illustrated aspect of FIG. 4 is the same as that described in FIG.
[0044] A collective shutdown is set in the shutdown setting unit 131. Therefore, shutdown is set for all of the interlocked terminals 221 and 221b, terminals 222a and 222b, and terminals 224a and 224b.
[0045] FIG. 4(A) shows the initial state of light-emitting elements 161-164 and light-emitting elements 171-174, all of which are off. When an alarm signal from detector 3, which is a factor in interlocking, is input, light-emitting elements 171, 172, and 174 corresponding to terminals 221a and 221b, terminals 222a and 222b, and terminals 224a and 224b, which are set for interlocking and for cut-off, turn on as shown in FIG. 4(B). At this time, because the cut-off confirmation mode is set, the sound device 7 and smoke control device 6, which are interlocking devices, will not operate even if a signal that is a factor in interlocking is input. Furthermore, in the cut-off confirmation mode, interlocking simulation display unit 16 does not change its display.
[0046] 5 is a diagram illustrating the display operations of the linked simulation display unit 16 and the linked cutoff display unit 17 in the cutoff confirmation mode according to embodiment 1. The illustrated aspect of FIG. 5 is the same as that described in FIG.
[0047] The cutoff setting unit 131 is set to a partial cutoff that cuts off the interlocking of the interlocking devices connected to the terminals 221a and 221b and the terminals 222a and 222b.
[0048] Fig. 5(A) shows the initial state of light-emitting elements 161-164 and light-emitting elements 171-174, all of which are off. When an alarm signal from detector 3, which is a factor in interlocking, is input, light-emitting elements 171 and 172 corresponding to terminals 221a and 221b and terminals 222a and 222b, which are set to interlocking and cut-off, turn on, as shown in Fig. 5(B). At this time, because the cut-off confirmation mode is set, the sound device 7 and smoke control and exhaust device 6, which are interlocking devices, will not operate even if a signal that is a factor in interlocking is input.
[0049] Furthermore, the light-emitting elements 174 corresponding to the terminals 224a and 224b that are not set to be cut off remain off, and the light-emitting elements 164 of the interlocking simulation display unit 16 are lit. This allows the operator to recognize that the interlocking is not set to be cut off for the terminals 224a and 224b. Note that because the cut-off confirmation mode is set, the interlocking devices connected to the terminals 224a and 224b will not operate even if an interlocking factor signal is input.
[0050] As described above, the fire receiver 1 of this embodiment is provided in correspondence with each of the plurality of disaster prevention devices and includes an interlocking simulation display unit 16 that indicates that the disaster prevention device is the interlocking destination, a mode setting unit 15 that sets the monitoring mode or the interlocking simulation mode, and a control unit 10. When the monitoring mode is set by the mode setting unit 15, the control unit 10 outputs a transfer signal to the disaster prevention device when the detector 3 activates an alarm, thereby interlocking the disaster prevention device. When the interlocking simulation mode is set by the mode setting unit 15, the control unit 10 does not output a transfer signal to the disaster prevention device when the detector 3 activates an alarm, but instead causes the interlocking simulation display unit 16 corresponding to the disaster prevention device to display an indication.
[0051] Therefore, inspectors can easily check the interlocking settings by viewing the interlocking simulation display 16 without interlocking the disaster prevention devices or checking the setup documents for each fire control device 1. For example, the person who sets the interlocking settings when installing the fire control device 1 performs the interlocking settings using a PC and dedicated software. However, the person who inspects the fire control device 1 is often different from the person who set it up, and using a PC and dedicated software may not be preferred from a workability perspective. For this reason, the interlocking settings can be checked by inserting a tester into the conduction holes for the test signal lines located near the detector line terminal block 21 and the signal transmission line terminal block 22. However, this requires inserting a tester for each terminal block, which takes time for inspection. However, according to this embodiment, it is possible to easily check the interlocking settings of the fire control device 1 as described above.
[0052] Furthermore, the fire receiver 1 of this embodiment is provided with an interlock cutoff display unit 17 that corresponds to each of the multiple disaster prevention devices and indicates that the disaster prevention device is the cutoff destination, and a cutoff setting unit 131 that sets the cutoff of the interlock. When the cutoff of the interlock is set by the cutoff setting unit 131 and the cutoff confirmation mode is set by the mode setting unit 15, when the detector 3 activates an alarm, the control unit 10 does not output a transfer signal to the disaster prevention device, but causes the interlock cutoff display unit 17 to display an indication that the interlock has been cut off.
[0053] Therefore, the inspector can easily check the contents of the interlock setting by looking at the interlock cutoff display unit 17 without having to check the setting documents for each fire receiver 1.
[0054] The fire receiving device 1 of this embodiment also includes a circuit board 20 to which terminals of the reporting line 5, which is a signal line that outputs a reporting signal to the disaster prevention device, are connected. The interlocking simulation display unit 16 includes light-emitting elements 161-164 mounted on the circuit board 20 at positions adjacent to the connection points of the terminals. The interlocking cutoff display unit 17 includes light-emitting elements 171-174 mounted on the board at positions adjacent to the connection points of the terminals. The interlocking simulation display unit 16 and the interlocking cutoff display unit 17 perform predetermined displays near the connection points of the signal lines of the reporting line 5, making it easy for an inspector to check the interlocking settings and cutoff settings for each of the multiple reporting lines 5.
[0055] (Variation 1) Instead of or in addition to providing the interlocking simulation display unit 16 and the interlocking cutoff display unit 17 on the circuit board 20, the interlocking simulation display unit 16 and the interlocking cutoff display unit 17 may be provided at an exposed position on the housing of the fire control panel 1, for example, on the front, side, or back of the housing. Specifically, for example, light-emitting elements corresponding to the light-emitting elements 161 to 164 and the light-emitting elements 171 to 174 are installed on the surface of the housing of the fire control panel 1. Even in this way, an inspector can easily check the contents of the interlocking settings.
[0056] (Variation 2) In the first embodiment, the person setting the interlocking settings configures the fire control device 1 using a personal computer and dedicated software. In addition to this configuration function, the content of the interlocking settings may be configured or changed by operating the fire control device 1. For example, the storage unit 18 stores an additional interlocking table that is not used in monitoring mode, separate from the interlocking table 181 used in monitoring mode. Then, upon receiving an operation on an input device provided on the fire control device 1, the control unit 10 performs interlocking control using the additional interlocking table instead of the interlocking table 181. More specifically, for example, the fire control device 1 has an evacuation drill button as an input device. When the evacuation drill button is operated, interlocking control is performed using the additional interlocking table stored in the storage unit 18. In the additional interlocking table, disaster prevention devices that should not be interlocked during evacuation drills may be removed from the interlocking destinations. This configuration allows the operator of the fire control device 1 to easily change the interlocking settings when temporarily changing the interlocking settings for situations other than normal monitoring mode, such as evacuation drills or inspections.
[0057] (Variation 3) In the first embodiment, an example is shown in which the fire receiver 1 is a P type, but the fire receiver 1 may also be an R type. When the fire receiver 1 is an R type, the sensor line 2 and the report line 5 may be connected to the fire receiver 1 via a repeater. In the case of a fire alarm system 100 having such a repeater, instead of providing the interlocking simulating display unit 16 and the interlocking cutoff display unit 17 on the circuit board 20 of the fire receiver 1, the interlocking simulating display unit 16 and the interlocking cutoff display unit 17 may be provided on a circuit board provided in the repeater.
