The probe of the circuit is a microwave sensing module RD9481, which is encoded by DTMF(dual-audio multi-frequency), the transmission of the alarm signal and address is done by the long wave transceiver unit T630／T631, the circuit can display the alarm spot, so it is suitable for multi-channel (16) integrated monitor alarm system. The circuit consists of the host and the extension, apart from the different address encode, all the extension circuits are the same.Alarm host circuit: Alarm extension circuit:
