In figure (a), when the detecting circuit TWH9250 is detecting the object signal, the terminal O is outputting a low LEV, and the relay K is connected. After the emitting circuit is connected with the power supply, the address code programmed by YYH26 is amplified by S&P27A and then emitted into the sky through the aerial. The detecting circuit is used to link to the working power source of the emitter, the address code emitted by the circuit represents the position of the emitter. In figure (b) is the multi-channel reception alarm circuit.
