  When the transmission / reception circuit 55 receives the interlock control signal, the transfer output unit 57 outputs the transfer signal from the transfer signal line L4 by the control of the control circuit 51.

  Next, the operation of the intercom system 100 in cooperation with the fire alarm device 10 will be described.

  In FIG. 1, for example, when a fire occurs in a dwelling unit on the 10th floor, 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.

  On the other hand, the repeater 50 performs the above-described operation in the same manner as the other fire alarm devices 40. 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, for example, the transfer input state in each dwelling unit is distinguished and displayed in correspondence with the individual emergency call line L3 for each floor. Thereby, the fire situation of each dwelling unit below a predetermined floor can be centrally managed by, for example, the existing centralized display 30.

  Here, for example, if a fire has occurred in a dwelling unit on the 11th floor due to the expansion of the fire, the fire receiver 400 receives a fire signal from the fire detector 200 on the 11th floor via the fire signal line L5. To do. And the fire receiver 400 outputs a report output signal based on the said fire signal from a report output part (not shown). As a result, in the centralized display 30, the control circuit 31 displays the message status on the display unit 33 based on the message output signal input to the message input unit 32 via the message output signal line L6. Let Here, the extent to which the management of the fire situation over a predetermined floor can be performed by the centralized display 30 depends on, for example, the fire signal processing capability of the fire receiver 400. For example, based on the fire signal from the fire detector 200, if it can be processed up to the transfer input state in each dwelling unit above the predetermined floor and can be included in the transfer output signal, management equivalent to the fire situation on the predetermined floor and below is possible. It can be carried out.

  As described above, in the first embodiment, when the fire alarm system 500 is configured with the fire detector 200, the speaker 300, and the fire receiver 400 provided above a predetermined floor, a fire is generated in a dwelling unit below the predetermined floor. An alarm device 40 and a relay device 50 are installed, and a fire alarm system is configured simply by connecting the relay device 50 to the transfer input unit 27 of the house information panel 20 in the intercom system 100 provided conventionally. Can do.

  In addition, a centralized indicator 30 is provided, and the fire situation of the dwelling unit in which the fire alarm 40 and the repeater 50 are installed can be centrally managed based on the transfer signal from the housing information panel 20 of the dwelling unit below the predetermined floor. it can. At this time, based on not only the transfer signal from the housing information board 20 in the dwelling unit below the predetermined floor, but also the transfer output signal from the fire receiver 400 that has received the fire signal from the fire detector 200 above the predetermined floor. Since the fire status is displayed, the centralized indicator 30 can perform the centralized management of the fire status of the entire apartment house including the existing system.

  Moreover, since the sound which concerns on the alarm is generated from the door phone 10, it can alert | report outside a dwelling unit.
