It has transfer circuits 142, 152, 162 for transferring information and commands between the building management panel 3 and the emergency broadcast facility operation panel 4.

Similarly, the fire detector 5 and the repeater 6 are respectively composed of the transmission circuits TRX4 and TRX5 and the address setting section A.
In addition to D4 and AD5, a detection unit 52 for detecting a fire and a terminal device that cannot be directly connected to the signal lines S + and S-, for example, a so-called general type, which is different from the fire detector 5 and does not have a transmission function. Fire detectors T1, T2, ...

In the fire receiver 1A thus constructed, when the detection section 52 of the fire detector 5 detects a fire that has occurred inside the building, the discrimination circuit 51 causes the address setting section AD to operate.
Fire signal with self address from 4 and transmission circuit TR
By transmitting to X4 and the signal line S + and S- to the transmission circuit 13, the transmission circuit 13 can recognize that this fire signal was emitted from the fire detector 5. Similarly, when the signal monitoring circuit 62 of the repeater 6 detects the presence of a fire signal from the fire detector, for example, T2, the determination circuit 61 transmits the fire signal together with its own address from the address setting unit AD5, so that the transmission circuit 13 receives the fire signal.

By transmitting to 4aA, the transfer unit 14aA can confirm that the received display signal is a signal to itself,
Therefore, this display signal is transferred to the CRT board 2 and displayed.

When the detection section 52 has a test circuit (not shown), the MPU 2 performs a test by operating a switch of the operation section 123 in the display / operation unit 12 to give a test input to the main unit 11A. When the signal is sent to the transmission circuit 13, the transmission circuit 13 attaches the address AD4 to the test signal and sends it to the detection unit 52 through the signal lines S + and S-, the transmission circuit TRX4 and the discrimination circuit 51 in the fire detector 5, This allows the fire detector 5 to undergo the necessary tests.

In the above embodiment, the signal line S of the transmission circuit 13 is used.

If the address is set individually, information and commands of each part can be transmitted and received by the only transmission circuit for the terminal. There may be any number of internal units, and if there are available addresses, it is possible to add more internal units at any time. When a plurality of terminal transmission circuits are provided (for fire monitoring, interlocking control, district sound control, etc.), the controlled unit may be provided in any transmission circuit.
