  Next, the operation of the above embodiment will be described.

  In FIG. 1, for example, when a fire occurs in the top floor dwelling unit, the fire alarm 40 near the fire source determines that the control circuit 41 is a fire based on the signal output by the fire detection circuit 47. Then, the alarm sound control circuit 48 and the indicator light circuit 49 are controlled to perform a fire alarm by sound and indicator light, and the transmitter / receiver circuit 45 is controlled so that other fire alarm devices 40 and repeaters 50 in the same dwelling unit are connected. In response, an interlock control signal is transmitted.

  When the other fire alarm device 40 receives the interlock control signal by the transmission / reception circuit 45, the control circuit 41 determines that the fire is detected by the other fire alarm device 40. Then, the alarm sound control circuit 48 and the indicator lamp circuit 49 are controlled to give a linked alarm by voice and indicator lamp. As the interlocking alarm, the sounding of the alarm sound and the light emission of the indicator lamp are different from the fire alarm, but they may be the same. In addition, the control circuit 41 controls the transmission / reception circuit 45 to transmit an interlock control signal to the other fire alarm device 40 and the relay device 50. Thus, by relaying the interlock control signal, the installation distance from the fire alarm 40 near the fire source that detected the fire is long, and the interlock control signal from the fire alarm 40 near the fire source that detected the fire is Even if there is a fire alarm 40 that cannot be received, the interlock control signal can be reliably received.

That is, when the interlock control signal is received by the transmission / reception circuit 55, the repeater 50 determines that the fire has been detected by the fire alarm 40 by the control circuit 51. Then, the alarm sound control circuit 58 and the indicator lamp circuit 59 are controlled to issue a linked alarm by voice and indicator lamp. Further, the control circuit 51 controls the transmission / reception circuit 55 to transmit an interlock control signal to the other fire alarm devices 40.

  Furthermore, when the interlock control signal is received by the transmission / reception circuit 55, the repeater 50 outputs a transfer signal from the transfer output unit 57 via the transfer signal line L 4 by the control circuit 51.

  When the relocation input unit 27 of the house information board 20 inputs a relocation signal via the relocation signal line L4, the relocation signal is output to the control circuit 21. When the transfer signal is input, the control circuit 21 outputs the transfer signal from the transfer output unit 28 to the centralized display 30 via the emergency notification line L3.

  In addition, the control circuit 21 performs voice output control of the voice output circuit 26 to output a voice message such as “A transfer signal has been input” from the speaker SP2. As a result, the fire situation in the dwelling unit can be centrally managed by the house information board 20.

  At this time, the control circuit 21 also turns on the call switch SW1 to connect the call circuit 13 of the door phone 10 and the call circuit 25 of the house information board 20 to each other. A voice message such as “I input” is output. The control circuit 21 also turns on the indicator lamp 15 of the door phone 10 via the indicator lamp line L1. As a result, the fire situation inside the dwelling unit can be informed outside the dwelling unit. The control circuit 21 controls the call switch SW1 to return to the original state after outputting the voice message.

  The transfer input unit 32 of the centralized display 30 outputs a transfer signal to the control circuit 31 when a transfer signal is input via the emergency notification line L3. When the transfer signal is input, the control circuit 31 displays the transfer input state on the display unit 33. At this time, the transfer input state in each dwelling unit is distinguished and displayed in correspondence with the individual emergency call line L3. Thereby, the fire situation of each dwelling unit can be centrally managed with the existing centralized indicator.

  As described above, in the first embodiment, when the fire alarm system is installed by installing the fire alarm device 40 and the repeater 50 in the necessary dwelling unit, the house information in the intercom system 100 that has been conventionally provided A fire alarm system can be configured by simply connecting the repeater 50 to the transfer input unit 27 of the panel 20 by wire.
