It uses Passive Dual Technology (PDT) — combining PIR sensing with microphonics — to register both body heat movement and subtle motions such as hand gestures, giving dependable coverage across a full cone beneath the ceiling. Designed for simple retrofit or new installs, the CMR PDT 9 works directly on line voltage, requires no external power pack, and offers adjustable time delays and push-button programming to match a variety of occupancy patterns.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the CMR PDT 9 detect people and small movements?\u003c\/h3\u003e\n\u003cp\u003eThe sensor pairs PIR sensing with microphonic inputs to create overlapping detection across the ceiling coverage area. PIR responds to thermal movement while microphonics pick up acoustic vibration from human activity, improving sensitivity to small gestures and slow motion that PIR alone might miss.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e360° conical coverage for complete room sensing.\u003c\/li\u003e\n  \u003cli\u003eOptimized for small motion within approximately a 12 ft radius.\u003c\/li\u003e\n  \u003cli\u003eMicrophonics filter reduces false triggers from non-occupant noises.\u003c\/li\u003e\n  \u003cli\u003eWorks at typical commercial ceiling heights of 8–15 ft.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat installation and compatibility options are available?\u003c\/h3\u003e\n\u003cp\u003eThe CMR is designed for straightforward ceiling mounting in common commercial junctions.
