Product Data Sheet    


Adaptive Technology Ultrasonic Ceiling Sensor
Hubbell ATU series sensors detect occupancy based on an ultrasonic signal. Since these sensors do not require line of sight to detect occupancy, they work particularly well in areas with obstructions such as restrooms and storage rooms. Another common application is hallways. An isolated relay and photocell are included on models with “RP” suffix. A CU series control unit is required for use with ATU series sensors.
