Description

  The present invention relates to a fire alarm repeater or the like in a fire alarm system.

  For example, a wireless fire alarm system capable of interlocking (notifying) a fire alarm by transmitting and receiving a fire-related signal between a plurality of fire alarms has been disclosed (for example, patent document) 1).

  In recent years, there has been a desire to alert and notify the state of the fire alarm system in an easy-to-understand manner by accurately outputting predetermined event information (for example, a fire radio signal) from the fire alarm system to an external device (external system). There is.

  Therefore, a fire alarm repeater that outputs a warning signal is sent to the external device when it receives a warning signal, although it does not have a fire detection function like a fire alarm system. It is conceivable to prepare inside. Here, examples of the external device (external system) include a housing information board (interphone system) and a flashlight device.

JP 2008-004033 A

  The equipment constituting the fire alarm system as described above has, for example, a linked inspection switch. Then, by turning on this interlocking inspection switch, it is possible to perform interlocking inspection for inspecting whether or not an alarm can be interlockedly performed between a plurality of devices, as in the case of a normal fire.

  However, for example, if the fire alarm repeater is operated in the same way as during a fire at the time of interlock inspection and a transfer signal is output, for example, sound output from a door phone, blinking of a light, etc., even though it is not actually a fire, etc. , It may be annoying for users.

Accordingly, an object of the present invention to obtain a fire alarm system that can enhance the convenience of the user.

The fire alarm system of the present invention can cause one or a plurality of fire alarms for performing a fire detection and one or a plurality of fire alarm repeaters to perform a linked alarm operation by transmitting and receiving radio signals. In a fire alarm system that can be configured, a fire alarm repeater relays between the fire alarm system and an external device, and a relay output unit that outputs a relay signal based on a radio signal, It is equipped with a transmission output setting means for setting whether to output a transmission signal based on a wireless signal for checking the interlocking of the equipment to the transmission output section, and detects a fire and performs an alarm operation When a radio signal related to the alarm stop from the fire alarm is received, the signal output by the message output unit is stopped, and other systems in the system other than the fire alarm that perform the alarm action by detecting a fire From the equipment Upon receiving a radio signal according to the broadcast stop, it is to continue Utsuriho signal output by the transfer paper output section without stopping.

The fire alarm repeater of the fire alarm system of the present invention further includes a linked inspection instruction input means, and when an instruction is inputted from the linked inspection instruction input means, the message is transferred regardless of the setting of the message output setting means. The transfer signal is output from the output unit.

Moreover, the fire alarm of the fire alarm system of the present invention is provided with interlocking inspection instruction input means, and the fire alarm and the fire alarm repeater operate in conjunction with an alarm operation when an instruction is input from the interlocking inspection instruction input means. In addition to performing a linked inspection alarm for performing the inspection of the above, other devices in the system also perform a linked inspection alarm .

In addition, the fire alarm and the fire alarm repeater of the fire alarm system of the present invention are provided with an alarm stop instruction input means, and when there are a plurality of fire alarms, the alarm stop instruction input means of the fire alarm device that detects a fire. When the alarm stop instruction is input, the alarms of the fire alarm that detects the fire and the fire alarm that is performing the alarm operation and the fire alarm repeater are stopped, and the alarm operation is performed in conjunction. When an alarm stop instruction is input to the alarm stop instruction input means of any fire alarm or fire alarm repeater, the alarms of the fire alarm and the fire alarm repeater that perform the alarm operation are stopped. To do .

  According to this invention, since the fire alarm repeater for relaying with the external device is provided with the transfer output setting means, whether or not the user outputs the transfer signal to the transfer output unit. Can be set arbitrarily. For this reason, for example, when there is no need to transfer information to an external device or the like at the time of interlocking inspection, it is not necessary to operate the external device in conjunction with the information transfer, so that convenience can be improved. In addition, it is possible to carry out the linked inspection with peace of mind without having to perform the linked inspection by operating external devices in consideration of the surroundings.

  Also, the fire alarm repeater is equipped with interlocking inspection instruction input means, and in response to the interlocking inspection instruction from the interlocking inspection instruction input means, the relocation signal is sent from the relocation output section regardless of the setting of the relocation output setting means. Therefore, the user can perform a linked inspection with an external device by inputting an instruction from the linked inspection instruction input means.

  In addition, when the wireless signal related to the alarm stop from the fire alarm that detected the fire is received, the alarm signal output from the alarm output unit is stopped, so the fire alarm of the fire source that detected the fire It can be set whether or not to continue the transfer output based on an instruction to stop the alarm when the alarm is operated or an instruction to operate another fire alarm. For this reason, it is possible to improve the convenience of the user and the like, such as determining the response to the fire source where the fire has occurred.

  And since the above fire alarm repeater was systematized with a fire alarm device, a highly convenient fire alarm system can be obtained.

  And in the multiple fire alarms in the fire alarm system, when an instruction to stop the alarm is input to the alarm stop instruction input means of the fire alarm associated with the fire source that detected the fire, the fire alarm that detected the fire And when the alarms of the fire alarm and the fire alarm repeater that perform the alarm action are stopped and the alarm stop instruction is input to the alarm stop instruction input means of other fire alarms, Since the alarms of the fire alarm and the fire alarm relay that are performing the alarm are stopped and the alarm of the fire alarm that detects the fire is not stopped, it is easy to determine the fire alarm be able to.

It is a figure showing the structure of the fire alarm system which concerns on embodiment of this invention. It is a figure for showing the circuit structure etc. of the fire alarm device. FIG. 3 is a diagram for illustrating a circuit configuration of the repeater 30 and the like. It is a figure showing the flowchart of the alarm process which concerns on the fire of the fire alarm device. It is a figure showing the flowchart of the process which concerns on the interlocking inspection of the fire alarm device. It is a figure showing the flowchart of the alarm process which concerns on the fire of the repeater. It is a figure showing the flowchart of the process which concerns on the interlocking inspection of the repeater.

  FIG. 1 is a diagram showing a configuration of a fire alarm system according to an embodiment of the present invention. The fire alarm system of the present embodiment includes one or more fire alarms 10 and one or more fire alarm repeaters 30 (hereinafter referred to as repeaters 30). In the system, a group is configured by devices that can transmit and receive radio signals. In the present embodiment, one parent fire alarm 10 is provided in the group, and the remaining devices are children. . In FIG. 1, the system has one group. For example, a plurality of groups can be configured in the system. Moreover, although not specifically limited, the fire alarm device 10 as a parent is basically provided at a position where it can communicate with all devices in the group. When an alarm signal or the like is received from another fire alarm device 10 or the like, it is retransmitted to other devices in the group so as to be reliably linked. For example, each device in the group has an address uniquely set in the group in order to specify the communication source and the communication destination.

  For example, when the fire alarm 10 detects a fire or the like, the fire alarm 10 gives an alarm by sound, display, etc., and notifies a user (for example, a resident). In addition, when an alarm signal relating to a fire is received from another fire alarm device 10 in the group, an alarm is issued in conjunction. Here, the fire alarm device 10 of the present embodiment has a function of checking whether or not the devices in the group can be interlocked and alarmed by a user operation.

  The repeater 30 is a device that performs relay when communicating with an external device in order to transfer (output) a signal related to the fire of the fire alarm system to an external device (including an external system). The repeater 30 of the present embodiment does not have a function of detecting a fire or the like, but can perform an alarm in conjunction with the signal from the fire alarm 10. Also, a unique address is set in the repeater 30 as in the case of the fire alarm device 10, and is treated as a child device in communication.

  FIG. 2 is a diagram for illustrating a circuit configuration and the like of the fire alarm device 10 according to the embodiment of the present invention. In FIG. 2, a fire alarm 10 includes a control circuit 1, a battery 2, a power supply circuit 3, a battery voltage detection circuit 4, a transmission / reception circuit 5, an antenna 6, a fire detection circuit 7, an alarm sound control circuit 8, a display circuit 9, and an inspection. An alarm stop switch 20 is provided.

  The control circuit 1 performs processing based on an input signal or the like, and controls a circuit or the like included in the fire alarm 10. For example, on the basis of a signal from the fire detection circuit 7, the alarm sound control circuit 8 and the display circuit 9 are operated to perform an alarm relating to fire by sound and display. Communication processing with other devices in the system (group) is performed via the transmission / reception circuit 5. The storage element 21 is, for example, a nonvolatile memory such as an EEPROM, and stores various data such as a program related to processing executed by the control circuit 1, addresses set in itself and other devices in the group, and group ID of the group to which it belongs. Storing.

  The battery 2 supplies DC power to the power supply circuit 3. The power supply circuit 3 controls the voltage of the battery 2 to a predetermined voltage and supplies it to each circuit of the fire alarm 10. The battery voltage detection circuit 4 detects a voltage related to the application of the battery 2 and outputs a battery voltage detection signal corresponding to the detected voltage to the control circuit 1.

  When it is determined that the remaining battery level is low or the battery depletion threshold value is exceeded based on the voltage detection signal from the battery voltage detection circuit 4, the control circuit 1 drives the alarm sound control circuit 8 and the display circuit 9. To let you know when the battery is dead.

  The transmission / reception circuit 5 is connected to an antenna 6 for transmitting / receiving a radio signal. The transmission / reception circuit 5 processes a radio signal input (sent) via the antenna 6 and includes its own address as communication destination data (including cases where all addresses are used as communication destinations). If it is determined, the reception process is performed. If it is determined that the radio signal is other than its own address, the reception process is not performed. The received signal is output to the control circuit 1. In addition, the transmission / reception circuit 5 performs transmission processing of a state signal and the like related to processing of the control circuit 1.

  The fire detection circuit 7 detects a physical change such as smoke or heat based on the fire phenomenon and outputs a signal corresponding to the detected content to the control circuit 1. Here, it demonstrates as what outputs the signal which concerns on the detection of fire, without distinguishing in particular in detail.

  The alarm sound control circuit 8 is a circuit for controlling an operation for generating an alarm sound from a buzzer / speaker or the like (not shown). The display circuit 9 is a circuit that controls the lighting operation of an indicator lamp such as a light emitting diode. Here, although it demonstrates as what is a circuit which performs lighting control of an indicator lamp, for example, when fire alarm 10 has a display means which can display a character, a number, etc., control which displays a character etc. May be performed.

  The inspection / alarm stop switch 20 serving as an instruction input means is a switch that is pressed by the user to cause the fire alarm 10 to perform interlocked inspection. Moreover, although it can also be set as another structure, in this Embodiment, at the time of the alarm which concerns on a fire, it shall also serve as the switch for a user to stop the alarm which concerns on a fire. Furthermore, the switch can be used properly by distinguishing, for example, half-pressing, full-pressing, short-pressing, long-pressing, or the like.

  FIG. 3 is a diagram for illustrating a circuit configuration and the like of the repeater 30 according to the embodiment of the present invention. In FIG. 3, the repeater 30 is similar to the fire alarm 10 in that it includes a control circuit 31, a battery 32, a power supply circuit 33, a battery voltage detection circuit 34, a transmission / reception circuit 35, an antenna 36, an alarm sound control circuit 38, and a display circuit 39. And an inspection / alarm stop switch 41. These circuits and the like basically perform the same operations as the corresponding circuits and the like of the fire alarm 10 described above. However, the control circuit 31 may perform processing different from the processing of the control circuit 1 of the fire alarm device 10 due to the difference in roles in the system. The control circuit 31 has a storage element 44 and stores various data such as a program for processing executed by the control circuit 31 and addresses set for itself and other devices in the group. And unlike the fire alarm device 10, since it does not detect a fire etc., the repeater 30 of this Embodiment shall not have the circuit corresponding to the fire detection circuit 7. FIG.

  Further, the repeater 30 of the present embodiment has a message output unit 40, a fire alarm sound output setting switch 42, and a message output setting switch 43. The transfer output unit 40 is configured to output (transmit) a transfer signal including an alarm signal related to a fire to an external device outside the system. The transfer output unit 40 is wired to an external device or the like, but may be wirelessly connected.

  The fire alarm sound output setting switch 42 is a switch (setting means such as a dip switch) for setting whether or not an alarm sound is generated in the repeater 30. Here, the fire alarm sound output setting switch 42 is set to generate a fire alarm sound. For this reason, the repeater 30 of the present embodiment is not related to the setting of the fire alarm sound output setting switch 42 for other sounds (for example, sounds related to abnormality notifications such as battery exhaustion, sensor abnormality, communication abnormality, etc.). Shall be generated. Also, the setting change by the fire alarm sound output setting switch 42 of the present embodiment becomes effective when the power is turned on and reset by a reset button (not shown) or the like. For this reason, it is assumed that the setting is not changed even when the switch is switched during normal operation.

  The transfer output setting switch 43 serving as a transfer output setting means is a switch for setting whether or not to output a transfer signal from the transfer output unit 40, for example, during linked inspection. Here, the transfer output setting means is constituted by a switch, but it is not particularly limited to the switch, for example, the setting made in accordance with the request is stored in the storage element 44 as a database. The same applies to the fire alarm sound output setting switch 42.

  In the present embodiment, a relay output setting switch 43 is provided in the repeater 30 in the fire alarm system. For example, when linked inspection of each device (fire alarm device 10 and repeater 30) in the system is performed, It is possible to set the presence or absence of a message output. At this time, when the inspection / alarm stop switch 41 is pressed in the repeater 30 and linked inspection is performed, the transmission output unit 40 is caused to perform the transmission output regardless of the setting of the transmission output setting switch 43. It is a thing.

  In addition, when performing a warning relating to a fire, if a signal relating to a warning stop is received from the fire alarm 10 relating to the fire source, the transfer output to an external device is stopped. On the other hand, when a signal related to the alarm stop is received from a device other than the fire source, the transfer output to the external device is continued.

  For the fire alarm 10, when the inspection / alarm stop switch 41 is pressed in the fire alarm 10 related to the fire source, the alarm in the equipment in the group is stopped, and the equipment other than the fire source is inspected. When the alarm stop switch 41 is pressed, the alarm in the equipment other than the fire alarm device 10 related to the fire source is stopped.

  FIG. 4 is a diagram illustrating a flowchart of alarm processing relating to a fire of the fire alarm device 10 according to the embodiment of the present invention. Next, based on FIG. 4, the alarm process which concerns on the fire which the control circuit 1 of the fire alarm device 10 performs is demonstrated.

  First, it is determined whether or not a signal is input from the fire detection circuit 7 (S1). If it is determined that a signal due to fire detection has been input, the place where it is installed becomes the fire alarm 10 of the fire source. Accordingly, the alarm sound control circuit 8 is operated to generate a sound or the like indicating that the fire is a fire, and the display circuit 9 is operated to display a fire source alarm for displaying the fire (S2). . Then, the transmission / reception circuit 5 is caused to transmit an interlock control signal for interlocking the alarm to other devices in the group via the antenna 6 (S3).

  On the other hand, if it is determined in S1 that a fire detection signal is not input from the fire detection circuit 7, it is determined whether an interlock control signal is received from another device via the antenna 6 and the transmission / reception circuit 5 ( S4). If it is determined that the interlock control signal has been received, the alarm sound control circuit 8 is operated to generate a sound indicating a fire at another location, and the display circuit 9 is operated to display a fire. An interlocking alarm is performed (S5). If it is determined that the interlock control signal has not been received, the process returns to S1, and determination of signal input from the fire detection circuit 7 and reception of the interlock control signal is performed at predetermined time intervals.

  Then, after giving an alarm, it is determined whether the inspection / alarm stop switch 20 is pressed and an instruction to stop the alarm is given (S6). If it is determined that the inspection / alarm stop switch 20 is pressed, the generation of sound by the alarm sound control circuit 8 and the display by the display circuit 9 are stopped, and the fire source alarm or the interlocking alarm is stopped (S7). And the transmission / reception circuit 5 is made to transmit the interlocking alarm stop signal for stopping the interlocking alarm of another apparatus via the antenna 6 (S8), and it returns to S1 and processes again.

  If it is determined in S6 that the inspection / alarm stop switch 20 has not been pressed, it is determined whether or not an interlocking alarm stop signal from another device has been received via the antenna 6 and the transmission / reception circuit 5 (S9). If it is determined that the interlock alarm stop signal has been received, the generation of sound by the alarm sound control circuit 8 and the display by the display circuit 9 are stopped, the interlock alarm is stopped (S10), and the process returns to S1 and the process is performed again. At this time, since only the interlock alarm is stopped, the fire alarm is not stopped in the fire alarm device 10 that performs the fire alarm. If it is determined that the interlocking alarm stop signal from another device has not been received, the process returns to S6 and an alarm is issued until the inspection / alarm stop switch 20 is pressed or a interlocking alarm stop signal from another device is received. continue.

  By performing the above processing, when the inspection / alarm stop switch 20 is pressed in the fire alarm 10 related to the fire source alarm, the own fire source alarm and the interlocking alarm in other devices are stopped. On the other hand, when the inspection / alarm stop switch 20 is pressed in the fire alarm device 10 related to the interlock alarm, the interlock alarm in the self and other devices stops (the fire alarm does not stop).

  FIG. 5 is a diagram illustrating a flowchart of processing relating to the interlocking inspection performed by the fire alarm device 10 according to the embodiment of the present invention. Based on FIG. 5, the process which the control circuit 1 of the fire alarm device 10 performs is demonstrated.

  For example, it is determined whether or not the inspection / alarm stop switch 20 is pressed and an instruction for interlocking inspection is given in a state where the fire source alarm and the interlocking alarm are not performed (S11). When it is determined that the inspection / alarm stop switch 20 has been pressed, the alarm sound control circuit 8 is operated to generate a sound at the time of the interlock inspection, and the display circuit 9 is operated to display the interlock inspection alarm (this implementation In the embodiment, an alarm similar to the fire source alarm) is performed (S12). And the transmission / reception circuit 5 is made to transmit the interlocking inspection signal for making the other apparatus in a group interlock | cooperate by interlocking inspection via the antenna 6 (S13), and it returns to S11 and processes again. .

  If it is determined in S11 that the inspection / alarm stop switch 20 has not been pressed, it is determined whether a linked inspection signal from another device has been received via the antenna 6 and the transmission / reception circuit 5 (S14). If it is determined that the interlocked inspection signal has been received, an interlocked inspection alarm (in the present embodiment, an alarm similar to the interlocked alarm) is performed (S15), and the process returns to S11 and is performed again.

  FIG. 6 is a diagram illustrating a flowchart of alarm processing relating to a fire of the repeater 30 according to the embodiment of the present invention. Next, based on FIG. 6, the alarm process which concerns on the fire which the control circuit 31 of the repeater 30 performs is demonstrated.

  First, it is determined whether an interlock control signal has been received from another fire alarm 10 or the like via the antenna 36 and the transmission / reception circuit 35 (S21). If it is determined that the interlock control signal has not been received, the determination of the interlock control signal reception is performed at predetermined time intervals.

  If it is determined that the interlock control signal has been received, it is determined whether or not the fire alarm sound output setting switch 42 is turned on (S22). If it is determined that the alarm signal is on, the alarm sound control circuit 38 and the display circuit 39 are operated to issue a linked alarm (S23). Further, the alarm output unit 40 is made to output an alarm alarm signal related to the fire (S24).

  On the other hand, if it is determined that the fire alarm sound output setting switch 42 is not turned on (turned off), the interlocking alarm is not performed, and the transition output unit 40 is caused to output a transition signal related to the fire alarm. Here, the interlock alarm is not performed when the fire alarm sound output setting switch 42 is OFF, but only the display circuit 39 may be operated to perform the alarm only for display. With this configuration, it is possible to respond to a user's request that it is desired to avoid the alarm sound from interfering but only to confirm the display.

  Then, it is determined whether the inspection / alarm stop switch 41 is pressed and an instruction to stop the alarm is given (S25). If it is determined that the inspection / alarm stop switch 41 is pressed, it is further determined whether or not the fire alarm sound output setting switch 42 is turned on (S26). If it is determined that it is on, the generation of sound by the alarm sound control circuit 38 and the display by the display circuit 39 are stopped, and the interlocking alarm is stopped (S27). Then, the transmission / reception circuit 35 is caused to transmit an interlocking alarm stop signal for stopping the interlocking alarm of another device via the antenna 36 (S28). On the other hand, the transfer output unit 40 continues to output the alarm transfer signal related to the fire (S29).

  On the other hand, if it is determined that the fire alarm sound output setting switch 42 is not turned on (is turned off), the interlocking alarm stop signal is not transmitted to the transmission / reception circuit 35, and the transfer output unit 40 is fired. Only the alarm signal is output continuously (S29). Thereby, when the fire alarm sound output setting switch 42 is off, even if the user presses the inspection / alarm stop switch 41, the operation becomes invalid. In addition, when performing the interlock alarm only for a display when the fire alarm sound output setting switch 42 is OFF, the interlock alarm only for a display is stopped. With this configuration, it is possible to respond to a user's request that it is desired to avoid the alarm sound from interfering but only to confirm the display.

  If it is determined in S25 that the inspection / alarm stop switch 41 has not been pressed, it is determined whether an interlocked alarm stop signal from another device has been received via the antenna 36 and the transmission / reception circuit 35 (S30). . If it is determined that the interlock alarm stop signal has been received, it is further determined whether or not the fire alarm sound output setting switch 42 is turned on (S31). If it is determined that it is turned on, the generation of sound by the alarm sound control circuit 38 and the display by the display circuit 39 are stopped, and the interlocking alarm is stopped (S32). On the other hand, if it is determined that the switch is not turned on (turned off), the next process is performed without performing the process related to the interlocking alarm. In addition, when performing the interlock alarm only for a display when the fire alarm sound output setting switch 42 is OFF, the interlock alarm only for a display is stopped.

  Next, based on the interlocking alarm stop signal related to reception, it is determined whether or not the signal transmission source is the fire alarm device 10 related to the fire source (S33). If it is determined that the fire alarm device 10 is related to the fire source, the transfer output unit 40 stops the output of the signal related to the fire alarm (S34), and the process returns to S21 to perform the process again. If it is determined that it is not the fire alarm device 10 related to the fire source, the transfer output unit 40 is made to continuously output the alarm transfer signal related to the fire (S29). Whether or not the fire alarm device 10 is a fire source can be determined by whether or not the address of the transmission source of the interlock control signal is the same.

  FIG. 7 is a diagram illustrating a flowchart of a process related to the linked inspection performed by the repeater 30 according to the embodiment of the present invention. Based on FIG. 7, the process which the control circuit 31 of the repeater 30 performs is demonstrated.

  For example, it is determined whether or not the inspection / alarm stop switch 41 is pressed in the state where notification by the interlocking alarm is not made and an instruction for interlocking inspection is made (S41). If it is determined that the inspection / alarm stop switch 41 has been pressed, it is further determined whether or not the fire alarm sound output setting switch 42 is turned on (S42). If it is determined that it is turned on, the alarm sound control circuit 38 is operated to generate a sound or the like at the time of the interlock inspection, and the display circuit 39 is operated to display the interlock inspection alarm (in this embodiment, An alarm similar to the interlocking alarm) is performed (S43).

  In addition, the transfer output unit 40 outputs a transfer signal related to the interlocked inspection warning (S44), and the process returns to S41 to perform the process again. At this time, not only when the transfer output setting switch 43 is on but also when it is off, the transfer signal related to the interlocked inspection alarm is output. Here, in this embodiment, when the inspection / alarm stop switch 41 of the repeater 30 is pressed, in order to inspect the repeater 30 and the external device, a signal related to the interlocked inspection alarm is output as a message. For example, the transmission / reception circuit 35 may be caused to transmit a linked inspection signal for other devices via the antenna 36 to perform a linked inspection with the fire alarm 10 or the like. Good.

  On the other hand, in S42, if it is determined that the fire alarm sound output setting switch 42 is not turned on (turned off), the transfer signal related to the linked inspection alarm is sent to the transferred output unit 40 without performing the linked inspection alarm. Is output. Here, when the fire alarm sound output setting switch 42 is OFF, the interlock inspection alarm is not performed, but only the display circuit 39 may be operated to perform the interlock inspection alarm only for display.

  If it is determined in S41 that the inspection / alarm stop switch 20 has not been pressed, it is determined whether or not an interlocked inspection signal from another device has been received via the antenna 36 and the transmission / reception circuit 35 (S45). If it is determined that the interlock inspection signal has been received, it is further determined whether or not the fire alarm sound output setting switch 42 is turned on (S46). If it is determined that it is turned on, the alarm sound control circuit 38 is operated to generate a sound or the like at the time of the interlock inspection, and the display circuit 39 is operated to display an interlock inspection alarm (S47). On the other hand, if it is determined that the switch is not turned on (turned off), the next process is performed without performing the process related to the linked inspection alarm. Here, when the fire alarm sound output setting switch 42 is OFF, the interlock inspection alarm is not performed, but only the display circuit 39 may be operated to perform the interlock inspection alarm only for display.

  Next, it is determined whether the transfer output setting switch 43 is on (S48). If it is determined that it is turned on, the transfer output unit 40 is caused to output a transfer signal related to the interlocked inspection warning (S49), and the process returns to S41 to perform the process again. On the other hand, if it is determined that it is not turned on (it is turned off), the process returns to S1 and the process is performed again without outputting the transfer signal related to the linked inspection alarm to the transfer output unit 40.

  As described above, according to the repeater 30 in the system of the present embodiment, the message output setting switch 43 serving as the message output setting means is provided, so that the user can send the message to the message output unit. Whether or not to output to 40 can be arbitrarily set. For this reason, when it is not necessary to transfer information to an external device at the time of interlocking inspection, it is not necessary to operate the external device in conjunction with the transfer, so that convenience can be improved. In addition, linked inspection can be performed with peace of mind.

  In addition, when the inspection / alarm stop switch 41 is pressed during the linked inspection, the transmission signal is output from the transmission output unit 40 regardless of the setting of the transmission output setting switch 43. Interlocked inspection can be performed.
