Description

  The present invention relates to an alarm device that performs an interlocking alarm when another detection device detects an abnormality, and an alarm system including the alarm device.

  As a conventional fire alarm system, when a certain fire alarm detects a fire, a radio signal including an interlock control signal is transmitted, and another fire alarm that receives the radio signal outputs an interlock alarm. As such an alarm device, “as long as at least one gas leak alarm device 1, 4, 5, or 8 that outputs an alarm signal remains, another gas leak alarm device 1 that does not output an alarm signal 1 , 4, 5, and 8 to continue the alarm state notification regarding the gas leak alarms 1, 4, 5, and 8 that output the alarm signal has been proposed (see, for example, Patent Document 1). .

JP 2007-094719 A (page 7)

  According to Patent Document 1, if one or more alarm devices out of a plurality of alarm devices output an alarm signal indicating an abnormality, the other alarm devices continue the interlocking alarm. If all alarm devices stop outputting alarm signals, the other alarm devices stop the interlocking alarm.

  Here, for example, an alarm device such as a fire alarm device is often provided with an alarm stop switch capable of stopping an alarm by a user operation. When the user recognizes that an alarm has been output by the alarm device and that an abnormality has occurred, the user first goes to the site where the error occurred and operates the alarm stop switch of the alarm device to stop the alarm, and then extinguishes the fire. We often take actions to eliminate abnormalities. In many cases, when a user goes to a fire site and operates an alarm stop switch of an alarm device, the user can be considered to have recovered from the fire condition.

  However, according to the technique of Patent Document 1, when one or more alarm devices that output an alarm signal remain, the interlock alarm is continuously output without being stopped. For this reason, even though the user has already gone to the fire site etc. to perform the fire extinguishing activity, other users who have known the interlock alarm that continues to output will also go to the fire site etc. Can occur.

On the other hand, there is an installation environment where it should be determined that an abnormal state such as a fire has been resolved only when all alarm devices no longer detect the abnormality. For example, in the case of fire alarms installed in buildings where vulnerable people live or where fires are likely to spread, it is better to keep linked alarms until all fire alarms stop detecting fire from the viewpoint of disaster prevention. Excellent.
For this reason, there has been a demand for an alarm device and an alarm system in which the user can set the interlock alarm stop condition in accordance with the installation environment of the alarm device.

  The present invention has been made in order to solve the above-described problems, and provides an alarm device and an alarm system capable of switching a stop condition of an interlocking alarm.

  The alarm device according to the present invention includes an abnormality detection unit that detects a physical change in the environment to detect an abnormality, and the control unit outputs an abnormality source alarm to the alarm unit when the abnormality detection unit detects an abnormality. The abnormality source alarm is stopped when the abnormality detection means stops detecting abnormality.

An alarm stop switch for stopping an alarm by the alarm means is provided, and the control means is provided with another alarm only when the abnormality detection means detects an abnormality when the alarm stop switch is operated. An alarm stop signal is transmitted to the device.
In the alarm device according to the present invention, the control unit stops the abnormality source alarm when the alarm stop switch is operated based on the setting of the first stop condition switching unit.

The alarm system according to the present invention includes a plurality of the alarm devices.
In the alarm system according to the present invention, one alarm device of the plurality of alarm devices includes a message output means for outputting a message signal to an external device when the interlock control signal is received. .

  The alarm device according to the present invention includes first stop condition switching means for setting whether or not to stop the interlocking alarm when receiving the alarm stop signal, and outputs the interlocking alarm based on the setting of the first stop condition switching means. Stop. For this reason, since the user can set whether or not to stop the interlocking alarm when the alarm stop signal is received, the interlocking alarm stop operation according to the installation environment of the alarm device or the like can be realized.

The alarm device according to the present invention includes an abnormality detection unit that detects a physical change in the environment to detect an abnormality, and the alarm unit outputs an abnormality source alarm when the abnormality detection unit detects an abnormality. For this reason, in addition to the interlocking alarm, the abnormality can be detected and the abnormality source alarm can be output by itself.
The alarm device according to the present invention comprises an alarm stop switch for stopping an alarm by the alarm means, and the control means detects an abnormality when the alarm stop switch is operated when the alarm stop switch is operated. The alarm stop signal is transmitted to the other alarm devices only when it is present.

In the alarm system 100 according to the present embodiment, the transfer adapter 50 and the flashlight 80 also function as slave units of the master unit 10a.

  The external device 200 is connected to the alarm system 100 via the transfer adapter 50. As the external device 200, for example, an alarm device such as an additional buzzer or a flashlight may be provided, a smoke-exhaust device such as a shutter or a fire door, a housing information panel of an interphone system, or the like may be provided.

(Configuration of fire alarm)
FIG. 2 is a functional block diagram showing the main configuration of the fire alarm according to the embodiment of the present invention. The 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, an indicator light circuit 9, and an alarm stop switch 12. And an interlocking alarm stop condition setting switch 13.

  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 the control circuit 1, the transmission / reception circuit 5, the fire detection circuit 7, the alarm sound control circuit 8, and the indicator lamp circuit 9.

  The battery voltage detection circuit 4 detects the voltage of the battery 2 applied to the power supply circuit 3 and outputs a battery voltage detection signal corresponding to the detected voltage to the control circuit 1. When the value of the battery voltage detection signal from the battery voltage detection circuit 4 indicates that the remaining battery level has decreased or exceeds the threshold for battery exhaustion, the control circuit 1 causes the alarm sound control circuit 8 and the indicator lamp circuit to 9 is driven, and the transmission / reception circuit 5 outputs a state signal including state information indicating that the battery has run out.

  The fire detection circuit 7 is an example of an anomaly detection means for detecting an anomaly by detecting a physical change in the environment. 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. Output to the control circuit 1. In the present embodiment, the case where the fire detection circuit 7 is a so-called thermal fire detection circuit will be described as an example. The fire detection circuit 7 is composed of a temperature sensor in which a fixed resistor (not shown) and a thermistor (not shown) are connected in series. An intermediate potential between the fixed resistor and the thermistor is an output terminal of the fire detection circuit 7, and a temperature detection signal is output to the control circuit 1 through this output terminal. The thermistor has a temperature characteristic in which its resistance value varies according to the environmental temperature. Since the temperature characteristic of the thermistor is linearized by the compensation fixed resistance, a detection voltage (temperature information) corresponding to the environmental temperature is input to the output terminal of the fire detection circuit 7.

  The alarm sound control circuit 8 is a circuit for controlling the sounding operation of sound or the like by a buzzer / speaker or the like. The indicator lamp circuit 9 is a circuit that controls the lighting operation of indicator lamps such as light emitting diodes. In the present embodiment, the alarm sound control circuit 8 and the indicator lamp circuit 9 correspond to the alarm means of the present invention.

  The transmission / reception circuit 5 is connected to an antenna 6 for transmitting / receiving a radio signal. The transmission / reception circuit 5 processes the radio signal input from the antenna 6 and performs reception processing in the case of a signal addressed to itself. In the case of other signals, reception processing is not performed. The received signal is output to the control circuit 1. The transmission / reception circuit 5 is controlled by the control circuit 1 to perform transmission processing of various signals.

Here, a signal transmitted by the transmission / reception circuit 5 will be described. Main signals transmitted by the transmission / reception circuit 5 include a status signal, an interlock control signal, a recovery signal, and an alarm stop signal.
The status signal is a signal that is periodically transmitted and received between the parent device and the child device during fire monitoring (steady state), for example, whether each device is operating normally. It is a signal for confirming whether or not. The status signal includes the address of the transmission source, the address of the other party, and any information indicating the status of the device such as the sensor status (deterioration, contamination, etc.) of the fire detection circuit 7 or a malfunction. Yes.

The interlock control signal is a signal transmitted to other devices such as the fire alarm device 10, the transfer adapter 50, and the flashlight 80 in the alarm system 100 when a fire is detected by the fire detection circuit 7. is there. This interlock control signal is a signal for informing the other device of the detection of the fire and causing the other device to output a predetermined interlock alarm. The interlock control signal includes the address of the transmission source, the address of the other party, and information indicating that a fire has been detected.
The recovery signal is a signal to be transmitted to other devices in the alarm system 100 when a fire is no longer detected after the fire is detected by the fire detection circuit 7. This recovery signal is a signal for notifying other devices of the recovery from the fire and stopping the interlocking alarm. The recovery signal includes the address of the transmission source, the address of the other party, and information indicating that the recovery has been performed.
The alarm stop signal is a signal that is transmitted to other devices in the alarm system 100 when the alarm stop switch 12 of the fire source fire alarm 10 is turned on. The alarm stop signal includes the address of the transmission source, the address of the other party, and information indicating that the alarm stop switch 12 is turned on. The alarm stop signal can be transmitted only by the fire alarm device 10 that has detected a fire. For example, even if the alarm stop switch 12 of the fire alarm device 10 that has not detected a fire is turned on, the alarm stop signal is not transmitted.

  The alarm stop switch 12 is a switch that is turned on in response to a pressing operation on an alarm stop button (not shown) provided on the housing of the fire alarm 10. When the alarm stop button is pressed by the user and the alarm stop switch 12 is turned on, the fire alarm 10 is stopped and the alarm stop signal is transmitted to other devices in the alarm system 100 if the fire alarm 10 detects itself. Send to.

  The interlock alarm stop condition setting switch 13 is a switch capable of setting a condition for stopping the output of an interlock alarm based on fire in response to an input to, for example, a slide switch or a rotary switch provided in the housing of the fire alarm 10. It is. The user can switch the interlock alarm stop condition to one of two patterns (described later) by a predetermined switch operation provided on the housing of the fire alarm 10. In addition to a predetermined switch operation provided on the housing, setting to the stop condition setting switch 13 of the interlocking alarm may be performed by communication, as long as the setting by the user is possible. The interlocking alarm stop condition setting switch 13 according to the present embodiment corresponds to the first stop condition switching means of the present invention.

  The control circuit 1 determines whether or not a fire has occurred based on the signal output by the fire detection circuit 7. When it is determined that a fire has occurred, the alarm sound control circuit 8 and the indicator lamp circuit 9 are controlled to perform a fire source alarm by sound and indicator lamp, and control related to alarm output / stop. In addition, the control circuit 1 performs necessary processing based on the signal received by the transmission / reception circuit 5 and controls the transmission / reception circuit 5 as necessary, such as a status signal to other fire alarms, an interlock control signal, and the like. Send a signal. In addition, the control circuit 1 performs various checks such as a remaining amount check of the battery 2 and a wireless communication function check at a predetermined timing. The fire detection means of the present invention corresponds to the fire detection circuit 7 and the control circuit 1 in the present embodiment.

  The storage element 11 is a nonvolatile memory such as an EEPROM, and various types of information such as a program executed by the control circuit 1, an address set individually for each fire alarm 10, and a group to which each fire alarm 10 belongs. Store information. In addition to these, the storage element 11 stores data shown in FIG.

FIG. 3 is a diagram illustrating a main configuration of information stored in the storage element 11.
The interlock alarm stop condition 14 stores a condition (details will be described later) for stopping the interlock alarm based on the fire detected by another fire alarm. The interlock alarm stop condition 14 can be arbitrarily set by the user using the interlock alarm stop condition setting switch 13.
The fire source address storage unit 15 stores the address of the fire alarm installed in the fire source, that is, the address of the fire alarm 10 that detects the fire. When the self detects a fire, the self address is stored, and when another fire alarm 10 detects a fire, the address is stored as a fire source address. If the fire alarm 10 that has detected a fire stops detecting a fire, the address of the fire alarm 10 is deleted from the fire source address storage unit 15.

(Configuration of news adapter)
FIG. 4 is a functional block diagram showing the main configuration of the transfer adapter 50 according to the embodiment of the present invention. The transfer adapter 50 includes a control circuit 51, a battery 52, a power supply circuit 53, a battery voltage detection circuit 54, a transmission / reception circuit 55, an antenna 56, an alarm sound control circuit 58, an indicator light circuit 59, an alarm stop switch 62, and an interlocking alarm stop. A condition setting switch 63 and a transfer output unit 70 are provided.
This transfer adapter 50 has the same configuration as that of the fire alarm device 10, and the description of the common configuration is omitted. That is, the control circuit 51, the battery 52, the power supply circuit 53, the battery voltage detection circuit 54, the transmission / reception circuit 55, the antenna 56, the alarm sound control circuit 58, the indicator lamp circuit 59, the alarm stop switch 62, and the interlocking alarm stop condition setting switch 63. Is 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, an alarm sound control circuit 8, an indicator light circuit 9, an alarm stop switch 12, and an interlocking alarm of the fire alarm 10. The stop condition setting switch 13 has a function corresponding to each.

The transfer adapter 50 does not include a fire detection circuit and does not perform fire detection. Moreover, since the transfer adapter 50 does not detect fire, it cannot be a fire detection source alarm device, and therefore does not transmit an alarm stop signal.
On the other hand, the transfer adapter 50 includes a transfer output unit 70. When the transfer output unit 70 receives the interlock control signal transmitted from the fire alarm device 10, the transfer output unit 70 transmits a transfer signal to the external device 200. Communication between the transfer output unit 70 and the external device 200 may be either wired communication or wireless communication.

(Configuration of flashlight)
FIG. 5 is a functional block diagram showing the main configuration of the flashlight 80 according to the embodiment of the present invention. The flashlight 80 includes a control circuit 81, a battery 82, a power supply circuit 83, a battery voltage detection circuit 84, a transmission / reception circuit 85, an antenna 86, an indicator lamp circuit 89, an alarm stop switch 92, and a linked alarm stop condition setting switch 93.
The flashlight 80 has a configuration common to that of the fire alarm device 10, and the description of the common configuration is omitted. That is, the control circuit 81, the battery 82, the power supply circuit 83, the battery voltage detection circuit 84, the transmission / reception circuit 85, the antenna 86, the indicator lamp circuit 89, the alarm stop switch 92, and the interlock alarm stop condition setting switch 93 are Functions corresponding to the control circuit 1, battery 2, power supply circuit 3, battery voltage detection circuit 4, transmission / reception circuit 5, antenna 6, indicator lamp circuit 9, alarm stop switch 12, and interlocking alarm stop condition setting switch 13. I have it.

The flashlight 80 does not include a fire detection circuit and does not perform fire detection. Further, although no alarm sound control circuit is provided and no sound alarm is output, an alarm sound control circuit may be provided. Further, since the flashlight 80 does not detect fire, it cannot be a fire detection source alarm device, and therefore does not transmit an alarm stop signal.
On the other hand, when the flashlight 80 receives the interlock control signal based on the fire detected by the fire alarm device 10, the flashlight 80 performs an interlock alarm by display by the indicator lamp circuit 89.

  In the alarm system 100 configured as described above, when a fire alarm 10 detects a fire, it outputs a fire source alarm and transmits an interlock control signal to other devices in the alarm system 100. Other devices that have received the control signal output an interlocking alarm.

(Outline of alarm system operation)
Next, the operation | movement outline | summary at the time of the fire detection of the alarm system 100 is demonstrated.
For example, when a fire occurs in a room where the child device 10b is installed in FIG. 1, the child device 10b detects the fire by the fire detection circuit 7, and the control circuit 1 controls the alarm sound control circuit 8 and the indicator light circuit 9. Then, fire source warning is given by voice or indicator light. Further, the slave unit 10b transmits an interlock control signal to the master unit 10a, the slave unit 10c, the transfer adapter 50, and the flashlight 80.
In the master unit 10a and the slave unit 10c that have received the interlock control signal transmitted by the slave unit 10b, the control circuit 1 controls the alarm sound control circuit 8 and the indicator light circuit 9 to output a interlock alarm by voice or indicator light. To do.
The transfer adapter 50 that has received the interlock control signal transmitted by the slave unit 10 b outputs an interlock alarm by voice or an indicator lamp, and outputs a report signal to the external device 200.
The flashlight 80 that has received the interlock control signal transmitted by the slave unit 10b outputs an interlock alarm by the indicator lamp.
As the fire alarm by the fire alarm 10, for example, a voice alarm “P, Hugh, Hugh, Fire, Fire” is output, and the indicator light is turned on in a predetermined manner indicating the fire alarm. it can.
As the interlocking alarm by the fire alarm device 10, for example, a voice alarm “P, Hugh, Hugh, or a fire in another place” is output, and the indicator light can be turned on in a predetermined state indicating the interlocking alarm. .

  The master unit 10a that has received the interlock control signal transmitted from the slave unit 10b transfers the interlock control signal to the other slave units 10c, the transfer adapter 50, and the flashlight 80. By doing in this way, the probability that another apparatus will receive an interlocking control signal can be raised. For example, even if another slave unit cannot receive the interlock control signal transmitted from the slave unit that caused the fire, it must receive the interlock control signal from the master unit and output the fire alarm in conjunction. Will be able to. The “fire alarm” and the “linked alarm” are collectively referred to as “fire alarm”.

Here, the stop condition of the interlock alarm of the fire alarm device 10, the transfer adapter 50, and the flashlight 80 will be described. FIG. 6 is a diagram for explaining the interlock alarm stop condition.
As shown in FIG. 6, there are a pattern 1 and a pattern 2 as the interlocking alarm stop conditions.
In pattern 1, the interlock alarm is stopped when the recovery signal is received, but the interlock alarm is not stopped when the alarm stop signal is received. This pattern 1 is set as an initial state.
In pattern 2, the interlocking alarm is stopped when the recovery signal is received and the alarm stop signal is received.
In any pattern, the point that the interlocking alarm is stopped when the recovery signal is received is common.
In addition, the setting which stops the fire source alarm when the alarm stop switch 12, 52, 92 is operated is also linked to the setting to stop the interlocking alarm when the alarm stop signal is received. That is, the stop condition of the fire alarm (fire alarm in the case of own alarm, linked alarm in the case of other alarms) based on the operation of the alarm stop switches 12, 52, 92 by the self and other alarm devices, etc. Is set.

  The interlock alarm stop condition patterns 1 and 2 are selected by the interlock alarm stop condition setting switches 13, 63, and 93 of the fire alarm 10, the transfer adapter 50, and the flashlight 80. In other words, the user can set a stop condition for the interlocking alarm by operating a predetermined switch provided on the casing of each device.

(Fire alarm operation)
Next, the detailed operation of the fire alarm 10 will be described. 7 and 8 are flowcharts for explaining an operation example of the fire alarm device 10 according to the embodiment.
The fire alarm 10 determines whether or not a fire has been detected by the fire detection circuit 7 (S101), and if a fire is detected (S101: Yes), stores the self address in the fire source address storage unit 15 ( S102), an interlock control signal is transmitted (S103). If no fire is detected (S101: No), the process proceeds to step S104.

  Next, it is determined whether or not the fire has been recovered (S104). If the fire is recovered (S104: Yes), the self address is deleted from the fire source address storage unit 15 (S105), and a recovery signal is displayed. Is transmitted (S106). If not recovered (S104: No), the process proceeds to step S107.

  Next, it is determined whether or not an interlock control signal has been received (S107). If the interlock control signal has been received (S107: Yes), the interlock control signal is transmitted to the fire source address storage unit 15 as the fire source address. The original address is stored (S108). When the interlock control signal has not been received (S107: No), the process proceeds to step S109.

  Next, it is determined whether or not a recovery signal has been received (S109). If a recovery signal has been received (S109: Yes), the source address of the recovery signal is erased from the fire source address storage unit 15 ( S110). When the recovery signal has not been received (S109: No), the process proceeds to step S111.

  Next, it is determined whether an alarm stop signal has been received (S111). If an alarm stop signal has been received (S111: Yes), the interlock alarm stop condition set by the interlock alarm stop condition setting switch 13 is determined. Is determined, and it is determined whether or not it is set to stop the interlocking alarm by the alarm stop signal (S112). The interlocking alarm is stopped by the alarm stop signal when the pattern 2 is set in the present embodiment. If the setting to stop the interlocking alarm by the alarm stop signal is made (S112: Yes), the source address of the alarm stop signal is deleted from the fire source address storage unit 15 (S113). When the setting for stopping the interlocking alarm by the alarm stop signal is not made (S112: No), or when the alarm stop signal is not received (S111: No), the process proceeds to step S114.

  Next, it is determined whether or not the alarm stop switch 12 is turned on (S114). If the alarm stop switch 12 is turned on (S114: Yes), whether the self-address is stored in the fire source address storage unit 15 or not. If it is confirmed (S115) and the self address is stored (S115: Yes), the switch operation for stopping the alarm is validated and an alarm stop signal is transmitted (S116). Subsequently, the interlock alarm stop condition set by the interlock alarm stop condition setting switch 13 is confirmed, and it is determined whether or not the interlock alarm is set to be stopped by the alarm stop signal (S117). That is, as described above, based on the operation of the alarm stop switch 12, it is determined whether or not the fire source alarm is set to be stopped. The interlocking alarm is stopped by the alarm stop signal when the pattern 2 is set in the present embodiment. If the setting is made to stop the interlocking alarm by the interlocking alarm stop signal (S117: Yes), the self address is deleted from the fire source address storage unit 15 (S118). If the alarm stop switch 12 is not turned on (S114: No), or if the self-address is not stored in the fire source address storage unit 15 (S115: No), the setting to stop the interlocking alarm by the alarm stop signal If not (S117: No), the process proceeds to step S119 of FIG.

The description of FIG. 8 is continued.
Next, it is confirmed whether or not the self-address is stored in the fire-source address storage unit 15 (S119). If the self-address is stored (S119: Yes), that is, the fire alarm device 10 is self-fire. In this case, a fire source alarm is output (S120).

  If the self-address is not stored in the fire-source address storage unit 15 (S119: No), it is determined whether or not the address of another fire alarm 10 is stored in the fire-source address storage unit 15 (S121). If the address of the other fire alarm 10 is stored in the fire source address storage unit 15 (S121: Yes), it is assumed that a fire has been detected in the environment where the other fire alarm 10 is installed, and an interlocking alarm is generated Output (S122). If the address of the other fire alarm device 10 is not stored in the fire source address storage unit 15 (S121: No), the alarm is stopped (S123).

(Transfer adapter, flashlight operation)
Since the transfer adapter 50 and the flashlight 80 perform the same operations as those shown in FIGS. 7 and 8, the differences will be mainly described with reference to FIGS.
The transfer adapter 50 and the flashlight 80 perform the operations after step S107 in FIG. In other words, the transfer adapter 50 and the flashlight 80 do not perform operations relating to fire detection and recovery, but only perform operations related to the interlocking alarm.
The transfer adapter 50 is characterized in that, in step S122, it outputs an interlocking alarm and also outputs a transfer signal to the external device 200.
In step S122, the flashlight 80 outputs only an interlocking alarm by the indicator lamp circuit 89, and does not output an audio alarm.

An operation example of the alarm system 100 configured as described above will be described.
For example, a fire alarm 10 installed in a room such as a living room where a user has a long time or a room where a disaster vulnerable person resides is set to a pattern 1 stop condition for interlocking alarms and installed in another room. The fire alarm 10 sets the interlock alarm stop condition to pattern 2. In this way, in the living room or the room where the vulnerable person lives, the interlocking alarm can be continued until the fire detector 10 that detects the fire stops detecting the fire, that is, until the fire is extinguished. Delay can be prevented. On the other hand, for rooms other than these, when the alarm stop switch 12 of the fire alarm 10 of the fire detection source is turned on, that is, when the user confirms the fire source and can be considered to have recovered from the fire state, it is linked. The alarm can be stopped.
That is, in the alarm system 100, when a plurality of fire alarms 10 have detected an abnormality, the fire alarms 10, 50, 80, etc. for which the pattern 1 is set as the interlocking alarm stop condition, Until the recovery signal from the fire alarm 10 is received, the interlocking alarm is continued. On the other hand, the fire alarms 10, 50, 80 having the pattern 2 as the stop condition of the interlocking alarm are It can be configured such that the interlocking alarm is continued until a recovery signal or an alarm stop signal is received from the fire alarm device 10.

As described above, according to the present embodiment, the interlock alarm stop condition setting switch 13 that can set whether to stop the interlock alarm when the alarm stop signal is received is provided. Then, the interlocking alarm is stopped based on the set interlocking alarm stop condition. For this reason, since the user can set the interlock alarm stop condition, the interlock alarm stop operation according to the installation environment of the fire alarm 10 can be realized.
In the above description, when the fire alarm 10 detects a fire, the fire alarm 10 transmits an interlock control signal to other devices in the alarm system 100, and thereafter, when the fire is no longer detected, Although the case where the recovery signal is transmitted to another device has been described as an example, when the fire alarm 10 detects a fire, the fire alarm device 10 continues to transmit the interlock control signal to the other device in the alarm system 100, and then It may be configured to stop transmission of the interlock control signal to other devices in the alarm system 100 when the fire is no longer detected. That is, the “recovery signal” includes a stop of transmission of the interlock control signal. At this time, it can be determined that the other device has received the recovery signal when it has received the interlock control signal and no longer receives the interlock control signal.

  In the above description, the case where the present invention is applied to an alarm system including a fire alarm device that is driven by a battery and performs wireless communication is described as an example, but the power supply method and communication method of the fire alarm device are limited. It is not a thing. Further, although the fire alarm device having a thermal fire detection circuit has been described as an example, the present invention is applied to a fire alarm device having a smoke type fire detection circuit and an alarm device for detecting abnormalities in other monitoring areas such as gas leakage. Can also be applied.
