In figure (a), when the detection circuit TWH9250 detects the target signal, the output port 0 of it outputs the low level, the relay K is connected. When the transmitter circuit gets the operating power supply, the address code which is edited by the coding circuit YYH26 is amplified by the ampP27A, and it is output by the antenna. The detection circuit can be used to connect the operating power supply of the transmitter, the transmitter circuit outputs the address code to indicate the detection place. Figure (b) shows the multi-channel receiver alarm circuit.
