Ceiling-mount occupancy sensor
The Acuity Sensor Switch CM PDT 9 detects occupancy using passive infrared and microphonic technology. It operates on 12 to 24V DC and covers up to 452 sq ft from a maximum mounting height of 15 ft. The unit supports 0-10V dimming for fluorescent, incandescent and LED lighting. A white finish and 4.5 in diameter suit standard ceiling installations.
Hard-wired setup with included screws
Installation is a hard-wired connection to a compatible control unit; load rating at 120V AC depends on that unit's rating. Two self-tapping screws are included for ceiling mounting. The sensor meets BAA, CA Title 24 and RoHS compliance. No wireless pairing or configuration is required, but the control unit must be correctly rated for the connected load.
Continuous coverage for occupied spaces
Under sustained occupancy the sensor maintains lighting control without time-out gaps, keeping 0-10V dimming signals stable for the connected load. The dual-technology detection reduces false triggers from air currents or minor vibrations. Performance scales with the control unit capacity, so the sensor does not limit the load beyond the unit's own rating.

Questions about this item
How can I confirm the sensor is detecting motion correctly after wiring it at 12 V DC?
The LED indicator on the CM PDT 9 flashes when occupancy is detected; walk through the 452 sq ft zone at 15 ft mounting height and verify the connected load responds.
What hardware is included and what must I supply for a hard-wired 0-10 V dimming installation?
The box contains the white ceiling-mount sensor and two self-tapping screws; you must provide the 12-24 V DC power source, 0-10 V control wiring, and a compatible control unit rated for the 120 V AC load.
Which coverage specification should I match to my room size when choosing this model?
Select the CM PDT 9 when the area is up to 452 sq ft and the ceiling height is 15 ft or less; its 4.5 in diameter fits standard ceiling openings.
