To reduce the occurrence of false ON events, the sensor employs PIR or ultrasonic technology to detect major motion. Once lighting has been turned on, it employs highly sensitive PIR and/or ultrasonic technology to detect minor motion and keep lighting on while areas remain occupied. When the room or area is no longer occupied, the sensor turns off lighting after pre-set time delay.

The low profile sensor is ceiling mounted for the greatest sensitivity to motion in the large areas with obstructions. With a 360 degree field of view and up to 2000 square feet of coverage area, the Ceiling Mounted Occupancy Sensor is ideal for conference rooms, Classrooms, multi-stall bathrooms, and large office areas.

The ceiling mount sensor also incorporates an integral photo sensor to prevent lighting from switching ON when sufficient ambient light is present, such as is commonly found in windowed areas.

Installation and configuration is simple. The sensor readily mounts to drop ceilings and features front located adjustments for setting sensitivity and time delay. The sensor also features an auxiliary relay for use with building automation and HVAC systems.
