The DX-60 enhances security by supervising Microwave and PIR signals and electronically reporting either PIR masking or microwave failure. Microwave shaping forms an 85 pattern which 'fits' rooms more easily, makes installation easy, and cuts down on microwave spillage. "Quad Zone Logic" PIR technology offers 'Pet Immunity' while at the same time maintaining high catch. Simplified jumper control for Long or Short range detection and 3 bright LEDs make installation fast and easy.
