Ceiling occupancy sensor for commercial lighting
The Hubbell ATD1000CL is a ceiling-mounted occupancy sensor designed for indoor commercial spaces. It combines passive infrared and ultrasonic detection to register presence across open areas. The unit operates on 120 to 277V AC supplies and installs with a hard-wired connection. A built-in relay switches connected lighting loads directly.
1000 sq ft coverage at up to 12 ft mounting height
The sensor covers a maximum area of 1000 square feet when mounted at heights up to 12 feet. At 120V AC it handles incandescent loads up to 1800W. The adaptive time delay adjusts automatically and can be set to a maximum of 40 minutes. Spaces larger than the stated coverage or higher mounting positions will need additional units.
ASHRAE 90.1 and cULus listed with low-profile
The white housing measures 4.5 inches in overall diameter and meets ASHRAE 90.1 energy-code requirements. It carries cULus listing and complies with UL244A. The hard-wired design draws minimal standby power while the dual-technology sensing reduces false triggers that waste energy.

Questions about this item
Will the 120 to 277V AC operating voltage work with my existing 120V lighting circuit?
Yes, the sensor operates on 120 to 277V AC, so it is compatible with standard 120V circuits and supports loads up to 1,800W incandescent at that voltage.
How can I verify the PIR and ultrasonic detection is covering the full 1,000 sq ft area after installation?
Walk through the space at the 12 ft maximum mounting height; the adaptive time delay up to 40 minutes will keep lights on while motion is detected, confirming coverage.
Does the box include the relay and mounting hardware, or do I need to buy a separate junction box?
The sensor includes the relay and is designed for ceiling mounting with a 4.5 in diameter; a compatible junction box must be supplied separately.
