PCB Size: 28 * 49mmQ1 and Q2 composed of two audio amplifier circuit, the audio signal is accepted by the MK1 C1 is coupled to the base of Q1 pole, amplified and fed directly from the collector to the base of Q2 to a negative square wave at the collector of Q2, with to trigger the bistable circuit. R1, C1 circuit frequency response is limited to about 3kHz to high sensitivity range. The power is turned on, the state of the bistable circuit Q4 off, Q3 saturated, D3 doesnot shine. When MK1 received control signal, and a negative square wave output after two enlarged, negative spikes through D1 add to the base of Q3, the circuit rapidly flip, D3 is lit after differential processing. When MK1 again connected to the control signal, the circuit and flipped, D3 is off. Circuitboard reserved for the terminal J1 access outside the control equipment and other devices through the J1 connector relay voice. (Then relays required at both ends of the relay coil anti and a diode)
