Ceiling mount occupancy sensor

The Hubbell ATD2000C is a hard-wired ceiling sensor that combines passive infrared and ultrasonic detection for commercial lighting control. It operates on a 24V DC supply and is designed for indoor installations up to 12 ft mounting height.

Check voltage and control unit rating

Verify that your lighting circuit provides a 24V DC source for the sensor. The load rating at 120V AC depends entirely on the connected control unit, so confirm that unit's specifications before wiring. Ensure the ceiling location allows the 4.5 in diameter housing.

Mounting hardware and adaptive delay included

The package supplies mounting hardware for direct ceiling installation. An adaptive time delay adjusts automatically to occupancy patterns, reducing manual setup. The white finish matches standard ceiling tiles and the unit carries cULus and UL244A listings for code compliance.

Questions about this item

What comes in the box with the ATD2000C and do I need a separate control unit?

The sensor includes mounting hardware; a separate control unit is required because the load rating at 120V AC depends on that unit's rating.

The specs list 24V DC and 120V AC — which voltage version should I choose?

The sensor itself operates on 24V DC and is designed to work with a control unit that handles the 120V AC load.

What does the 2,000 sq ft coverage mean once the sensor is mounted on a 12 ft ceiling?

At the maximum 12 ft mounting height the dual PIR and ultrasonic sensor can detect occupancy across up to 2,000 sq ft.
