(1) Door sensor-transmitter and (1) receiver-sounder

Model DA4DAC is the basic Model DA4D system (complete set motion sensor with remote sounder), for doors or entrys that are open or closed, with the added feature of being able to use power supply for the motion sensor /transmitter), for those locations with high traffic, to eliminate battery replacement.
