Each wireless signal includes a unique code that matches the unique code stored in the second storage device 13S of the second fire alarm 10S12 and an abnormality warning message. Therefore, the second control device 15S of the second fire alarm device 10S12 performs the second abnormality alarm operation, and the second abnormality occurrence alarm device 122S outputs an abnormality alarm.

The wireless signal from the first fire alarm 10M2 is also received by the first fire alarm 10M1 and 10M3. The wireless signal from the first fire alarm 10M2 includes neither a common code nor a unique code that matches the unique code stored in the first storage device 13S of each of the first fire alarms 10M1 and 10M3. Accordingly, the first fire alarms 10M1 and 10M3 ignore the wireless signal from the first fire alarm 10M2. Therefore, even if the second test device 17S of the second fire alarm device 10S11 finds an abnormality, the fire alarm device 10 of the other fire alarm systems S2 and S3 does not output an abnormality alarm.

When the first test device 17M of the first fire alarm 10M1 of the fire alarm system S1 finds an abnormality, the first control device 15M performs a first abnormality alarm operation and a first abnormality notification operation. Thereby, the first abnormality occurrence alarm 122M of the first fire alarm 10M1 outputs an abnormality alarm. The first transmitter / receiver 14M transmits a radio signal that includes the unique code stored in the first storage device 13M and the abnormality warning message and does not include the common code stored in the first storage device 13M.

The radio signal from the first fire alarm 10M2 is also received by the first fire alarm 10M1 and 10M3, but the first fire alarm 10M1 and 10M3 ignore the radio signal from the first fire alarm 10M2. Therefore, even if the first test device 17M of the first fire alarm 10M1 finds an abnormality, the fire alarm 10 of the other fire alarm systems S2 and S3 does not output an abnormality alarm.

Thus, in this embodiment, only the fire alarm device 10 belonging to the same fire alarm system S is interlocked and outputs an abnormality alarm. That is, when there is an abnormality in the fire detector 11 or the fire occurrence alarm 121 of the fire alarm 10, an abnormality alarm is also output from another fire alarm 10 installed in the same house H as the fire alarm 10. The Thereby, it is possible to prevent the abnormality of the fire alarm device 10 from being overlooked.

Note that the abnormality occurrence alarm device 122 may be configured to continue outputting an abnormality alarm for a predetermined time. Each fire alarm device 10 may be configured to end the output of the abnormality alarm from the abnormality occurrence alarm device 122 when the input device 16 receives a predetermined input. In this case, the fire alarm devices 10 belonging to the same fire alarm system S may be configured to end the output of the abnormality alarm in conjunction with each other.

Main controller 30 has a function of transmitting a radio signal (simultaneous test signal) including, for example, a unique code of fire alarm system S and a test execution message. The main controller is disposed at a position where at least the first fire alarm 10M can receive a simultaneous test signal. For example, the main control device is installed in a manager room of an apartment house such as an apartment. If the main control device transmits a simultaneous test signal, all the fire alarms 10 of the fire alarm system S of each house (dwelling unit) can be tested. The main controller 30 may be configured to communicate with the fire alarm device 10 in a wired manner.

In the present embodiment, the first fire alarm 10M of each fire alarm system S installed in the adjacent house H is configured to wirelessly communicate with each other. However, the radio signal may not reach depending on the distance between the houses H. In this case, the first fire alarm devices 10M may be connected to each other by wire so that the first fire alarm devices 10M of different fire alarm systems S can perform communication by wire.

(Embodiment 2)
The fire alarm system S of this embodiment includes one first fire alarm 10M and a plurality of second fire alarms 10S.

Each fire alarm 10 of the fire alarm system S of the present embodiment is different from the fire alarm 10 of the first embodiment in a storage device 13 and a control device 15. In addition, since the other structure of each fire alarm 10 was already demonstrated in Embodiment 1, description is abbreviate | omitted.

The storage device 13 in the present embodiment stores a periodic monitoring message for confirming (periodic monitoring) whether or not the second fire alarm 10S is operating normally.

The control device 15 in the present embodiment is configured to selectively perform asynchronous communication and synchronous communication.

Asynchronous communication is wireless communication that transmits and receives wireless signals intermittently. In asynchronous communication, the control device 15 performs radio wave reception check at every predetermined intermittent reception interval (however, the intermittent reception interval is longer than the transmission period). The control device 15 measures the intermittent reception interval using a timer or the like. In the reception check, the control device 15 activates the transmitter / receiver 14 to check whether a desired radio wave (a radio signal transmitted by another fire alarm device 10) can be received. When the desired radio wave cannot be received, the control device 15 immediately stops the operation of the transceiver 14. If the desired radio wave can be received, the control device 15 continuously operates the transmitter / receiver 14 in order to receive radio signals from the other fire alarms 10. The control device 15 performs a reception check based on a received signal strength indication signal (ReceivingceivSignal Strength Indication: RSSI) output from the transceiver 14. The control device 15 determines that a desired radio wave has been received if the magnitude of the received signal strength display signal is equal to or greater than a predetermined threshold. The received signal strength indication signal is a DC voltage signal proportional to the strength of the signal received by the transceiver 14.

Synchronous communication is TDMA (Time Division Multiple Access) wireless communication.

The first control device 15M in the present embodiment has a function of executing a regular monitoring operation. In the periodic monitoring operation, the first control device 15M causes the first transmitter / receiver 14M to periodically transmit a radio signal including the unique code and the periodic monitoring message stored in the first storage device 13M. For example, the first controller 15M causes the first transmitter / receiver 14M to transmit a radio signal including a unique code and a regular monitoring message every 25 hours.

The second control device 15S in the present embodiment is configured to execute an inspection operation. In the inspection operation, the second control device 15S checks whether or not the fire detector 11S is out of order and whether or not the remaining amount of the battery of the power supply device 18S is sufficient at a constant cycle (for example, one hour cycle). The second control device 15S stores the confirmed result in the second storage device 13S.

Further, the second control device 15S waits if the radio signal received by the second transceiver 14S includes the unique code stored in the second storage device 13S and includes a fire alarm message or a regular monitoring message. It is configured to perform a response action after time has elapsed. In the response operation, the second control device 15S causes the second transceiver 14S to transmit a radio signal including the identification information and the response message stored in the second storage device 13S. The response message is a message indicating the result of the confirmation stored in the second storage device 13S by the periodic monitoring operation.

The second storage device 13S of the second fire alarm 10S stores the above-described standby time. The standby time is set according to the identification information stored in the second storage device 13S, that is, the identification information of the second fire alarm 10S (for example, the slave ID that is the identification code of the second fire alarm 10S). . Further, the standby time is different for each fire alarm 10. For example, in this embodiment, the standby time corresponding to the second fire alarm 10S1 is zero. The standby time corresponding to the second fire alarm 10S2 is T1 (> 0). The standby time corresponding to the second fire alarm 10S3 is T2 (> T1). The standby time corresponding to the second fire alarm 10S4 is T3 (> T2). In addition, if the subunit | mobile_unit ID is a number, you may set standby | waiting time according to the quotient which divided | segmented subunit | mobile_unit 1D by arbitrary numbers, and a remainder.

As shown in FIG. 3B, when the second fire alarm 10S1 receives the radio signal from the first fire alarm 10M, it immediately transmits a radio signal including a response message ACK. When the second fire alarm 10S2 receives the radio signal from the first fire alarm 10M, the second fire alarm 10S2 transmits a radio signal including a response message ACK after the standby time T1 has elapsed. Similarly, the second fire alarm 10S3 transmits a radio signal including a response message ACK after the standby time T2 has elapsed since the reception of the radio signal from the first fire alarm 10M, and the second fire alarm 10S4 receives the first fire alarm. The wireless signal including the response message ACK is transmitted after the waiting time T3 has elapsed from the reception of the wireless signal from the device 10M.

Thus, each second fire alarm 10S transmits a radio signal including a response message ACK at different timings. Therefore, the radio signal from the second fire alarm 10S does not collide with the radio signal from another second fire alarm 10S. Thereby, it is possible to shorten the time required for the first fire alarm 10M to receive the radio signals of all the second fire alarms 10S after transmitting the radio signals to the second fire alarm 10S all at once.

If the signal received by the second transceiver 14S includes the identification information stored in the second storage device 13S and the fire alarm message, the second control device 15S performs the second alarm start operation. Composed. Further, the second control device 15S is configured to include the identification information stored in the second storage device 13S in the radio signal transmitted by the second transceiver 14S.

The first control device 15M is configured to execute the first diagnostic operation after executing the periodic monitoring operation. In the first diagnostic operation, the first control device 15M determines whether the first transmitter / receiver 14M has received a radio signal including the identification information and the response message stored in the first storage device 13M. The abnormality of the alarm device 10S is determined. Furthermore, when the first transmitter / receiver 14M receives the wireless signal including the identification information and the response message stored in the first storage device 13M, the first control device 15M receives the second fire alarm based on the content of the response message. It is determined whether the container 10S is abnormal.

For example, the first control device 15M transmits the wireless signal including the periodic monitoring message to the first transmitter / receiver 14M, and the first transmitter / receiver 14M stores the identification information and the response stored in the first storage device 13M within a predetermined time. If the wireless signal including the message cannot be received, it is determined that an abnormality has occurred in the second fire alarm device 10S that has not obtained a response message.

When the first control device 15M determines that there is an abnormality in at least one second fire alarm device 10S by the first diagnosis operation, the first control device 15M performs an abnormality occurrence alarm operation. In the abnormality occurrence alarm operation, an abnormality alarm that reports that there is an abnormality in the second fire alarm device 10S is output to the abnormality occurrence alarm device 122M.

The first control device 15M is configured to execute a second diagnostic operation after transmitting a radio signal including a fire alarm message. In the second diagnosis operation, the first control device 15M determines whether the first transmitter / receiver 14M has received a radio signal including the identification information and the response message stored in the first storage device 13M. The abnormality of the container 10S is determined. The first control device 15M determines that the second fire alarm device 10S that is the transmission source of the fire alarm message is normal.

The first control device 15M is configured to execute a re-notification operation when determining that there is an abnormality in at least one second fire alarm device 10S by the second diagnosis operation. In the re-notification operation, the first control device 15M first transmits a wireless signal (re-notification signal) including identification information corresponding to the second fire alarm device 10S determined to be abnormal in the second diagnosis operation and a fire alarm message. Transmit to the transceiver 14M. When the first transmitter / receiver 14M receives the wireless signal including the identification information and the response message corresponding to the second fire alarm device 10S determined to be abnormal in the second diagnostic operation within a predetermined time after transmitting the re-notification signal. The first control device 15M determines that there is no abnormality in the second fire alarm device 10S determined to be abnormal in the second diagnosis operation, and ends the re-notification operation. Even if the number of times the re-notification signal is transmitted reaches the specified number, the first transceiver 14M is wireless including identification information and a response message corresponding to the second fire alarm device 10S determined to be abnormal in the second diagnostic operation. If the signal cannot be received, the first controller 15M ends the re-notification operation. When the first control device 15M performs the re-notification operation, a communication path between the first fire alarm device 10M and the second fire alarm device 10S is easily established. The prescribed number of times may be one time or may be two or more times.

By the way, in the second diagnostic operation, the first control device 15M may determine whether or not the second fire alarm 10S is abnormal based on the content of the response message obtained from the second fire alarm 10S. . If the response message can be obtained, there is a possibility that the second fire occurrence alarm 121S can output a fire alarm. Therefore, in the re-notification operation, the second fire alarm device 10S determined to be abnormal based on the content of the response message may be set as a re-notification signal transmission target.

The first control device 15M is configured to execute a synchronous operation when it obtains a result that there is no abnormality in any of the second fire alarm devices 10S in the second diagnostic operation. In addition, when the re-notification operation is performed, the first control device 15M is configured to execute the synchronization operation after the re-notification operation is completed. In the synchronous operation, the first controller 15M causes the first transmitter / receiver 14M to transmit a synchronization signal at a constant period. The synchronization signal is a signal that defines a time slot necessary for performing TDMA wireless communication between a plurality of fire alarms 10. The time corresponding to the transmission period (one period) of the synchronization signal includes a plurality of time slots. One time slot is assigned to every second fire alarm 10S. The first fire alarm device 10M transmits a message to the second fire alarm device 10S in a synchronization signal. The second fire alarm 10S stores a message for the first fire alarm 10M in a time slot and transmits it. Therefore, radio signals transmitted by the fire alarm 10 do not collide with each other. The operation of assigning the time slot to each fire alarm device 10 is performed when the second fire alarm device 10S is registered in the first fire alarm device 10M.

FIG. 4 shows a frame format of a radio signal transmitted and received by the fire alarm 10. The frame of the radio signal includes a preamble PA that is a synchronization bit, a unique word UW that is a frame synchronization pattern, a header HD, data Data, and a cyclic redundancy check code CRC. The header HD includes an identification code (hereinafter referred to as “parent device ID”) of the first fire alarm device 10M, a count value RC of a registration counter, a transmission source address SA, and a transmission destination address DA. The data Data includes various messages.

Each fire alarm 10 is configured to receive a radio signal (receive a radio signal message) if the transmission destination address DA of the radio signal matches its identification information (for example, a device number). . In addition, each fire alarm 10 is configured to receive a radio signal if the transmission address DA of the radio signal is a special bit string (for example, a bit string that is all 1) different from any device number. This special bit string is, for example, the above-described unique code.

In addition, when transmitting the radio signal asynchronously, the control device 15 causes the transmitter / receiver 14 to continuously transmit the radio signal for one frame by the number that can be transmitted within one transmission period. When transmitting a radio signal by the TDMA method, the control device 15 stores a radio signal for one frame in one time slot.

As described above, in the fire alarm system S of the present embodiment, the first fire alarm 10M performs a regular monitoring operation. In the periodic monitoring operation, the first control device 15M of the first fire alarm 10M generates a frame including the unique code and the periodic monitoring message stored in the first storage device 13M, as shown in FIG. To the first transceiver 14M. The first transceiver 14M converts the frame obtained from the first controller 15M into a radio signal and transmits it.

Each of the second fire alarm devices 10S1 to 4 receives a radio signal from the first fire alarm device 10M. This radio signal includes a unique code that matches the unique code stored in the second storage device 13S of the second fire alarm 10S and a periodic monitoring message. For this reason, each of the second fire alarm devices 10S1 to 10S4 performs a response operation. Accordingly, each of the second fire alarm devices 10S1 to 10S4 transmits a radio signal including the response message ACK.

Here, the second fire alarm 10S executes a response operation after the above-described standby time has elapsed. Therefore, even if each of the second fire alarm devices 10S1 to 10S4 receives the radio signal from the first fire alarm device 10M almost simultaneously, each of the second fire alarm devices 10S1 to 10S4 has a radio signal including a response message ACK at different timings. Send.

In the first fire alarm device 10M, the first control device 15M executes the first diagnosis operation. If no response message indicating that there is no abnormality in the second fire alarm device 10S is obtained from all the second fire alarm devices 10S1 to 10S4, the first control device 15M determines that there is an abnormality in the second fire alarm device 10S. to decide. Therefore, the first control device 15M performs an abnormality occurrence alarm operation. As a result, the first fire alarm 10M outputs an abnormality alarm that reports that there is an abnormality in the second fire alarm 10S.

Thus, in the fire alarm system S, it is confirmed whether or not the communication path between the first fire alarm 10M and the second fire alarms 10S1 to 10S4 under its control is normal. In the fire alarm system S, the fire alarm device 10 is interlocked by transmitting wireless signals including various messages from the first fire alarm device 10M to the second fire alarm devices 10S. In the fire alarm system S, it is not necessary to confirm whether or not the communication path between the second fire alarm devices 10S is normal. Therefore, it is possible to suppress the consumption of the battery of the power supply device 18S of the second fire alarm device 10S by performing the operation of confirming whether or not the communication path between the second fire alarm devices 10S is normal.

Hereinafter, the operation of the fire alarm system S of the present embodiment will be described with reference to FIG. In the following description, it is assumed that the fire alarm system S of the present embodiment has one first fire alarm device 10M and four second fire alarm devices 10S (10S1 to 10S4).

When the fire detector 11S of the second fire alarm 10S1 detects a fire, the second fire alarm 10S1 outputs a fire alarm. The second fire alarm 10S1 transmits a radio signal including the unique code and the fire alarm message stored in the second storage device 13S.

As described above, the second control device 15S of the second fire alarm 10S1 repeatedly transmits a radio signal during the transmission period, and switches the second transmission / reception 14S to the reception state during the suspension period (reception period). The other fire alarm 10 performs intermittent reception asynchronously with the second fire alarm 10S1. Even in such a case, the other fire alarm device 10 can receive the fire alarm message M1 by repeating the transmission period of the second fire alarm device 10S1 a certain number of times (for example, three times).

小 With low-power radio, it is possible to keep one area of a normal house within the radio communication range. However, the radio signal from the second fire alarm device 10S1 may not reach the other second fire alarm devices 10S2 to 10S4 due to the influence of an obstacle or the like.

However, since the first fire alarm 10M is installed at a position where it can communicate with all the second fire alarms 10S1 to 10S4, it receives a radio signal from the second fire alarm 10S1. In this case, the first fire alarm device 10M outputs a fire alarm and transmits a radio signal including a unique code and a common code stored in the first storage device 13M and a fire alarm message.

The second fire alarms 10S2 to 10S4 receive radio signals from the first fire alarm 10M or the second fire alarm 10S1. The wireless signal includes a unique code that matches the unique code stored in the second storage device 13S of the second fire alarm 10S and a fire alarm message. Therefore, the second fire alarm devices 10S2 to 10S4 execute the second alarm start operation. Therefore, the second fire alarm devices 10S2 to 10S4 output a fire alarm.

Furthermore, the second fire alarm devices 10S2 to 10S4 execute a response operation. Thereby, each of the second fire alarm devices 10S2 to 10S4 transmits a radio signal including the identification information stored in the second storage device 13S and the response message ACK.

Here, the second fire alarm device 10S executes a response operation after the standby time stored in the second storage device 13S has elapsed. Therefore, even if each second fire alarm device 10S receives the radio signal from the first fire alarm device 10M or the second fire alarm device 10S1 almost simultaneously, the second fire alarm devices 10S2 to 10S4 have different timings. A radio signal including a response message ACK is transmitted.

The first control device 15M of the first fire alarm 10M transmits a radio signal including a fire alarm message, and then executes a second diagnosis operation. When the first control device 15M receives wireless signals including response messages from all the second fire alarm devices 10S2 to 10S4 other than the second fire alarm device 10S1, the first control device 15M performs a synchronization operation. In the synchronous operation, the first control device 15M uses the first time slot as the second fire alarm 10S1, the second time slot as the second fire alarm 10S2, and the third time slot as the second fire alarm. 10S3 is assigned a fourth time slot to the second fire alarm 10S4.

Here, when the response message cannot be obtained from the second fire alarm device 10S2, the first control device 15M performs a re-notification operation. After the re-notification operation is completed, the first control device 15M performs a synchronization operation.

On the other hand, when the first fire detector 11S of the first fire alarm 10M detects a fire, the first fire alarm 10M outputs a fire alarm. The first fire alarm 10M transmits a radio signal including the unique code and the common code stored in the first storage device 13M and the fire alarm message.

The second fire alarms 10S1 to 10S4 receive radio signals from the first fire alarm 10M. The wireless signal includes a unique code that matches the unique code stored in the second storage device 13S of the second fire alarm 10S and a fire alarm message. Therefore, the second fire alarm devices 10S1 to 10S4 execute the second alarm start operation and the response operation. Therefore, the second fire alarm devices 10S1 to 10S4 output a fire alarm. Further, the second fire alarm devices 10S1 to 10S4 transmit radio signals including the identification information stored in the second storage device 13S and the response message ACK.

When the first control device 15M of the first fire alarm 10M receives radio signals including response messages from all the second fire alarms 10S1 to 10S4, the first control device 15M executes a synchronization operation.

Thus, after at least one fire alarm 10 detects a fire, the first fire alarm 10M and all the second fire alarms 10S perform wireless communication (synchronous communication) by the TDMA method.

In the synchronous communication, the first control device 15M of the first fire alarm 10M causes the first transmitter / receiver 14M to transmit a synchronization signal including a fire alarm message. The second controller 15S of the second fire alarm 10S checks whether or not the fire alarm 121S is outputting a fire alarm every time it receives a synchronization signal. If the fire occurrence alarm 121S does not output a fire alarm, the second control device 15S causes the fire occurrence alarm 121S to output a fire alarm.

As described above, after at least one fire alarm 10 detects a fire, the first fire alarm 10M and all the second fire alarms 10S perform wireless communication by the TDMA method. Therefore, radio signals from the plurality of second fire alarm devices 10S do not collide with each other.

The operating state of the fire alarm system S of the present embodiment includes a standby state, an interlocking ringing state, and an interlocking stop state. The standby state is a state where no fire alarm 10 detects a fire. In the standby state, the first fire alarm 10M communicates with the second fire alarm 10S asynchronously. The interlocking sounding state is a state where all the fire alarms 10 are sounding an alarm sound (a state where a fire alarm is output). The interlocking stop state is a state in which only the fire source fire alarm 10 continues to output the fire alarm.

When there is no fire, the fire alarm system S is in standby mode. When the fire alarm 10 detects a fire, the operation state of the fire alarm system S changes from a standby state to a linked ringing state. Thereafter, when the fire alarm 10 receives an alarm stop input, the operation state of the fire alarm system S changes from the interlocking ringing state to the interlocking stop state.

The first control device 15M causes the first storage device 13M to store fire detection information indicating the fire detection status of each fire alarm 10. The first control device 15M updates the fire detection information every predetermined time. When all the fire alarms 10 no longer detect a fire, the operation state of the fire alarm system S becomes a standby state.

When the operation state of the fire alarm system S changes from the interlocking sounding state to the interlocking stop state, the first control device 15M starts to measure the alarm sound stop time (for example, 5 minutes). After the warning sound stop time has elapsed, the first control device 15M refers to the fire detection information stored in the first storage device 13.

If none of the fire alarms 10 senses a fire, the first control device 15M causes the first transmitter / receiver 14M to transmit a synchronization signal including a recovery notification message for ending communication by the TDMA method. When the second fire alarm device 10S receives the recovery notification message, the second fire alarm device 10S ends the communication by the TDMA method. Further, the second fire alarm 10S transmits a radio signal including a response message. When the first fire alarm device 10S receives response messages from all the second fire alarm devices 10S, the transmission of the synchronization signal is terminated. In this way, the operation state of the fire alarm system S is changed from the interlock stop state to the standby state.

If at least one fire alarm 10 senses a fire, the first controller 15M causes the first transmitter / receiver 14M to transmit a synchronization signal including a fire alarm message. As a result, the operation state of the fire alarm system S is changed from the interlock stop state to the interlock ringing state.

Even when the fire alarm 10 newly senses a fire when the fire alarm system S is in the interlock stop state, the first control device 15M transmits a synchronization signal including a fire alarm message. Therefore, the operation state of the fire alarm system S changes from the interlock stop state to the interlock ringing state.

Hereinafter, the operation of the fire alarm system S will be described with reference to FIGS. In the following, it is assumed that the fire alarm system S includes one first fire alarm device 10M and three second fire alarm devices 10S (10S1 to 10S3).

When the first fire alarm 10M detects a fire when the operation state of the fire alarm system S is in the standby state, the operation state of the fire alarm system S changes from the standby state to the interlocking sounding state. In this case, when the second fire alarm 10S3 accepts an alarm stop input, the second fire alarm 10S3 transmits a radio signal including an alarm stop message M2.

When the first fire alarm device 10M receives the wireless signal from the second fire alarm device 10S3, the first fire alarm device 10M transmits a synchronization signal including an alarm stop message. At the same time, the first fire alarm device 10M starts measuring the alarm sound stop time.

If the fire is not extinguished at this time, the first fire alarm 10M continues to output the fire alarm. If the fire is not extinguished even after the alarm sound stop time has elapsed, the first fire alarm 10M transmits a synchronization signal including the fire alarm message M1 again.

Therefore, the operation state of the fire alarm system S is changed from the interlock stop state to the interlock ringing state (see FIG. 5).

If the fire is stopped within the warning sound stop time, the first control device 15M transmits a synchronization signal including the recovery notification message M3 after the warning sound stop time has elapsed (see FIG. 6). When the second fire alarm 10S receives the synchronization signal including the recovery notification message M3, the second fire alarm 10S transmits a radio signal including the response message ACK. When the first fire alarm device 10M receives the response message ACK from all the second fire alarm devices 10S1 to 10S3, the transmission of the synchronization signal is terminated. As a result, the communication between the first fire alarm 10M and the second fire alarm 10S is changed from synchronous communication to asynchronous communication. In this way, the operation state of the fire alarm system S is changed from the interlock stop state to the standby state.

When the second fire alarm 10S3 senses a fire and the operation state of the fire alarm system S changes from a standby state to an interlocking ringing state, when the fire stops, the second fire alarm 10S3 to the first fire alarm A recovery notification message is sent to 10M (see FIG. 7). The first fire alarm 10M that has received the recovery notification message refers to the fire detection information stored in the first storage device 13M. If no fire alarm 10 senses a fire, the first fire alarm 10M transmits a synchronization signal including a recovery notification message M3. When receiving the response messages ACK from all the second fire alarm devices 10S1 to 10S3, the first fire alarm device 10M ends the transmission of the synchronization signal. Therefore, the operation state of the fire alarm system S changes from the interlock stop state to the standby state.

When the second fire alarm 10S3 senses a fire and the fire alarm system S changes from a standby state to an interlocking ringing state and the fire stops, the second fire alarm 10S3 to the first fire alarm A recovery notification message is sent to 10M.

Here, it is assumed that the second fire alarm 10S2 senses a new fire before the second fire alarm 10S3 sends the recovery notification message (see FIG. 8). In this case, the second fire alarm 10S2 transmits a fire alarm message. Upon receiving this fire alarm message, the first fire alarm 10M updates the fire detection information in the first storage device 13M.

Thereafter, when a recovery notification message is received from the second fire alarm device 10S3, the first fire alarm device 10M refers to the fire detection information in the first storage device 13M. Since the recovery notification message has not been received from the second fire alarm device 10S2, the first fire alarm device 10M determines that the second fire alarm device 10S2 senses a fire. Therefore, the first fire alarm 10M transmits a synchronization signal including the fire alarm message M1 instead of transmitting a synchronization signal including the recovery notification message M3. Therefore, the operation state of the fire alarm system S remains in the interlocking ringing state.

Hereinafter, the operation of the first fire alarm 10M (first control device 15M) will be described with reference to the flowchart of FIG.

If the fire alarm message is received from the second fire alarm device 10S when the operation state of the fire alarm system S is the standby state (Yes in S11), the first control device 15M updates the fire detection information (S12). For example, the fire detection information about the second fire alarm 10S that is the transmission source of the fire alarm message is changed from non-fire detection to fire detection.

When the recovery notification message is received from the second fire alarm 10S that has transmitted the fire alarm message (Yes in S13), the first control device 15M updates the fire detection information (S14). For example, the fire detection information about the second fire alarm 10S that has transmitted the recovery notification message is changed from fire detection to fire non-detection.

When the alarm state message is received from the second fire alarm device 10S when the operation state of the fire alarm system S is the fire interlocking state (Yes in S15), the first control device 15M1 terminates the output of the fire alarm and stops the alarm. A synchronization signal including a message is transmitted to the first transceiver 14M (S16).

In addition, the first fire alarm 10M periodically sends a synchronization signal including an alarm stop message until the alarm sound stop time elapses after the operation state of the fire alarm system S changes from the interlock sounding state to the interlock stop state. (S16, S17, S18).

After the lapse of the alarm sound stop time (Yes in S18), the first control device 15M refers to the fire detection information in the first storage device 13M to determine whether there is a fire alarm 10 that is detecting a fire (S19). ).

If there is a fire alarm device 10 during fire detection (Yes in S19), the first control device 15M causes the first transmitter / receiver 14 to transmit a synchronization signal including a fire alarm message (S20).

If there is no fire alarm 10 under fire detection, that is, if the fire detection information of all the fire alarms 10 is non-detection of fire (No in S19), the first control device 15M sends a synchronization signal including a recovery notification message. The first transmitter / receiver 14 is caused to transmit (S21).

When the first fire alarm device 10S receives response messages ACK from all the second fire alarm devices 10S within a predetermined period after the transmission of the synchronization signal including the recovery notification message, the first fire alarm device 10S ends the transmission of the synchronization signal. Here, if the response message ACK cannot be received from at least one second fire alarm 10S, the first fire alarm 10S notifies the second fire alarm 10S that has not yet received the response message ACK. A synchronization signal (recovery notification signal) including a message is sent. If the response message cannot be obtained from all the second fire alarm devices 10S even when the number of times of transmission of the recovery notification signal reaches the specified number, the first fire alarm device 10S ends the transmission of the synchronization signal.

Note that the second control device 15S stops the operation of the second transmitter / receiver 14S if the synchronization signal cannot be received within a predetermined period (for example, a time that is several times the transmission period of the synchronization signal). In this way, the power of the second fire alarm device 10S is wasted when the first fire alarm device 10M breaks down and cannot transmit the synchronization signal (the battery of the power supply device 18 is wasted). Can be prevented.

Note that the first control device 15M may have a registration function for assigning device numbers so as not to overlap each second fire alarm 10S.

The device number is represented by a bit string shorter than the identification code (child unit ID). For example, a slot number indicating the order of time slots can be used as the device number. When the slot numbers of the second fire alarm devices 10S1 to 10S4 are “1” to “4”, the device numbers “1” to “4” are assigned to the second fire alarm devices 10S1 to 10S4, respectively. Further, a device number “0” is assigned to the first fire alarm 10M.

The device number can be used as identification information instead of an identification code. Therefore, if the device number of each fire alarm device 10 is registered in advance using the registration function, the device number can be used instead of the child device ID. For example, in the frame of the synchronization signal, the device number of the first fire alarm 10M can be used instead of the parent device ID of the header HD. In addition, the device number can be used in place of the identification code of each fire alarm 10 for the transmission source address SA and the transmission destination address DA of the header HD. Since the device number is a bit string shorter than the identification code, the bit length of the header HD can be shortened by using the device number. Therefore, the time for transmitting and receiving the radio signal can be shortened, and as a result, the power required for transmitting and receiving the radio signal can be reduced. Therefore, battery consumption of the power supply device 18 can be suppressed.

Also, the standby time may be set according to the device number.

The control device 15 periodically executes a test operation based on the time of the clock device 192. In the test operation, the control device 15 operates the test device 16.

When the abnormality of the fire detector 11 or the fire occurrence alarm 121 is found by the test operation, the control device 15 performs an abnormality notification operation and an internal alarm operation.

In the abnormality notification operation, the control device 15 causes the transmitter / receiver 14 to transmit a signal (failure alarm request signal) including the unique code stored in the storage device 13 and the abnormality alarm message. The content of the abnormality alarm message is determined according to the abnormality discovered by the test operation. Therefore, the type of failure is specified by the failure alarm request signal.

In the internal alarm operation, the control device 15 causes the alarm device 12 to output an abnormality alarm corresponding to the type of abnormality (failure alarm corresponding to the type of failure). If there is an abnormality in the fire detector 11, the control device 15 causes the fire occurrence alarm device 121 to output a voice message such as “An abnormality has occurred in the fire detector of this fire alarm. Further, the control device 15 causes the abnormality occurrence alarm 122 to blink. When the speaker 1211 of the fire occurrence alarm 121 is disconnected, the control device 15 causes the abnormality occurrence alarm 122 to blink.

If there is an abnormality in the fire detector 11 of another fire alarm 10, the control device 15 fires a voice message such as "An abnormality has occurred in the fire detector of another fire alarm. Please check." The generation alarm 121 is output. Further, the control device 15 causes the abnormality occurrence alarm 122 to blink. When the speaker 1211 of the fire alarm 121 of another fire alarm 10 is disconnected, the control device 15 sends a voice message such as “Speakers of other fire alarms are disconnected. The fire alarm 121 is output. Further, the control device 15 causes the abnormality occurrence alarm 122 to blink.

In the abnormality alarm operation, the control device 15 outputs an abnormality alarm that reports that there is an abnormality in the other fire occurrence alarm device 10 to the fire occurrence alarm device 121 by voice and causes the abnormality occurrence alarm device 122 to blink.

If the signal received by the first transmitter / receiver 14M includes the unique code and the abnormality alarm message stored in the first storage device 13M, the first controller 15M performs the first abnormality alarm operation in addition to the first abnormality alarm operation. 1 Anomaly notification operation is executed.

The control device 15 performs an abnormality alarm operation when the human sensor 191 detects a person after the transmitter / receiver 14 receives a signal including the unique code and the abnormality alarm message stored in the storage device 13.

That is, even if the fire alarm 10 finds an abnormality in the test operation, the fire alarm 10 does not immediately output the abnormality alarm but prepares to output the abnormality alarm. The fire alarm 10 outputs an abnormality alarm when the human sensor 191 detects a human body. Moreover, the fire alarm device 10 prepares for output of an abnormality alarm even when a failure alarm command signal is received. The fire alarm 10 outputs an abnormality alarm when the human sensor 191 detects a human body.

The control device 15 performs an abnormality alarm operation when the clock device 192 indicates a predetermined time after the transmitter / receiver 14 receives a signal including the unique code and the abnormality alarm message stored in the storage device 13. It may be. The predetermined time is preferably a time included in the resident's life time zone.

In this way, an abnormality alarm is output from the fire alarm 10 during the resident's life time, so that the resident can be surely noticed that the fire alarm 10 has failed.

As described above, if there is an abnormality such as contamination of the fire detector 11 or disconnection of the speaker 1211, the fire alarm 10 outputs an abnormality alarm corresponding to the abnormality that occurred.

For example, when the second fire alarm 10S1 detects an abnormality (failure), the second fire alarm 10S1 outputs an abnormality alarm corresponding to the type of abnormality from the second alarm device 12S. The second fire alarm 10S1 transmits a failure alarm request signal. When the first fire alarm 10M receives the failure alarm request signal, the first fire alarm 10M outputs an abnormality alarm corresponding to the abnormality identified by the failure alarm request signal from the first alarm device 12M. In addition, the first fire alarm 10M transmits a failure alarm request signal. When the second fire alarm device 10S2 or 10S3 receives the failure request signal from the first fire alarm device 10M or the second fire alarm device 10S1, the second alarm device outputs an abnormality alarm corresponding to the abnormality identified by the failure alarm request signal. Output from 12S.

For example, when the first fire alarm 10M detects an abnormality (failure), the first fire alarm 10M outputs an abnormality alarm corresponding to the type of abnormality from the first alarm device 12M. In addition, the first fire alarm 10M transmits a failure alarm request signal. When receiving the failure request signal from the first fire alarm device 10M, the second fire alarm devices 10S1 to 10S3 output an abnormality alarm corresponding to the abnormality identified by the failure alarm request signal from the second alarm device 12S.

When the first control device 15M receives the abnormal alarm stop signal from the first input device 16M, the first control device 15M performs a first abnormal alarm stop operation and a first abnormal alarm stop notification operation.

In the first abnormality alarm stop operation, the first control device 15M causes the first alarm device 12M to stop outputting the abnormality alarm. In the first abnormality alarm stop notification operation, the first controller 15M transmits a signal (alarm stop command signal) including the unique code and the abnormality alarm stop message stored in the first storage device 13M to the first transmitter / receiver 14M. Let

Furthermore, the first controller 15M performs the first abnormality alarm stop operation and the first abnormality if the signal received by the first transmitter / receiver 14M includes the unique code and the abnormality alarm stop message stored in the first storage device 13M. 1 The abnormal alarm stop notification operation is executed.

When the second control device 15S receives the abnormality alarm stop signal from the second input device 16S, the second control device 15S performs a second abnormality alarm stop notification operation.

In the second abnormality alarm stop notification operation, the second control device 15S transmits a signal (alarm stop request signal) including the unique code and the abnormality alarm stop message stored in the second storage device 13S to the second transceiver 14S. Let

If the signal received by the second transceiver 14S includes the unique code stored in the second storage device 13S and the abnormal alarm stop message, the second control device 15S executes the second abnormal alarm stop operation.

In the second abnormality alarm stop operation, the second control device 15S causes the second alarm device 12S to stop outputting the abnormality alarm.

In addition, when the transmitter / receiver 14 receives an alarm stop command signal while preparing for output of an abnormal alarm (standby), the control device 15 stops (releases) preparation of an abnormal alarm output. Further, when the control device 15 receives an abnormality alarm stop signal from the input device 16 during preparation for abnormality alarm output (standby), the controller 15 stops preparation for abnormality alarm output.

For example, when the second fire alarm 10S1 accepts an abnormal alarm stop input, the second fire alarm 10S1 ends the output of the abnormal alarm and transmits an alarm stop request signal. When the first fire alarm 10M receives the alarm stop request signal, the first fire alarm 10M ends the output of the abnormality alarm and transmits an alarm stop command signal. When the other second fire alarm devices 10S2 and 10S3 receive the alarm stop command signal from the first fire alarm device 10M or the second fire alarm device 10S1, the output of the abnormality alarm is terminated.

For example, when the first fire alarm 10M receives an abnormal alarm stop input, the first fire alarm 10M ends the output of the abnormal alarm and transmits an alarm stop command signal. When the second fire alarms 10S1 to 10S3 receive the alarm stop command signal from the first fire alarm 10M, the output of the abnormality alarm is terminated.

Next, with reference to FIG. 12, the operation when the disconnection of the speaker 1211 occurs in the second fire alarm 10S1 will be described.

As a result, the second fire alarm 10S1 causes the second abnormality alarm 122S, which is a display device, to blink (S103). Further, the second fire alarm 10S1 transmits a failure alarm request signal (S104). When receiving the failure alarm request signal from the second fire alarm device 10S1 (S201), the first fire alarm device 10M blinks the first abnormality alarm device 122M and outputs a failure alarm from the first fire alarm device 121M (S202). Further, the first fire alarm 10M transmits a failure alarm command signal (S203). When the second fire alarm device 10S2, 10S3 receives the failure alarm command signal from the first fire alarm device 10M (S301, S401), the second abnormality alarm device 122S blinks and the second fire alarm device 121S A failure alarm is output (S302, S402).

When the second fire alarm 10S2 accepts an abnormal alarm stop input (S303), an alarm stop request signal is transmitted (S304). When the first fire alarm 10M receives the alarm stop request signal (S204), the first abnormality alarm 122M stops blinking, and the abnormality alarm output from the first alarm alarm 121M ends (S205). ). Further, the first fire alarm 10M transmits an alarm stop command signal (S206). When the second fire alarm 10S1 receives an alarm stop command signal from the first fire alarm 10M (S105), the second abnormality alarm 122M ends blinking (S106). When the second fire alarm 10S2, 10S3 receives an alarm stop command signal from the first fire alarm 10M (S305, S403), the second abnormality alarm 122M stops blinking and the second fire alarm 121M The output of the abnormality alarm from is terminated (S306, S404).

As described above, in the fire alarm system S of the present embodiment, each fire alarm 10 has an abnormality alarm corresponding to an abnormality (such as contamination of the fire detector 11 or disconnection of the speaker 1211) that has occurred in another fire alarm 10. Is output by voice.
