The IOS-CMP-DT-U Dual Technology Line Voltage Occupancy Sensors control loads based on occupancy and ambient light levels. It combines passive infrared (PIR) and ultrasonic technologies to help avoid false triggering while increasing presence detection. Selectable modes allow the sensor to turn load ON and hold it ON as long as either or both technologies detect occupancy. If no movement is detected for a user-specified time of 5 seconds to 30 minutes, the load is turned OFF. The occupancy sensor provides a 360 coverage pattern, up to 1600 ft2 (150m2) for PIR and 1000 ft2 (93m2) for Ultrasonic sensor.
