Transmitter: the relay K and SCR VS are used to control the power of transmitter circuit. IC1 forms alarm sound signal circuit. The transistor V and its peripheral components form RF oscillator circuit to transmit the alarm signal. When the circuit is in the waiting state, the switch S1 is connected, and SB1 is disconnected(the front lock is locked), K is in the release state, the alarm transmitter does not work. When the front lock is opened (SB1 is connected), VS is triggered and turned on, K pulls in, the transmitter gets power. When SB1 is switched on, the normal open point of K-2 will be self-locking, at this time, the S1 being disconnected can stop the alarm.
