Sensor occupancy relay 1600sqft 110.. wall white

Dual technology occupancy sensor with self-adaptive feature. Ultrasonic combined with passive infrared sensing provide high sensitivity, high noise immunity and excellent false tripping immunity. Suited for complex environments that are difficult to control with single-technology sensors. Use in rooms with pendant fixtures and storage areas. Flexible base mounting on wall or ceiling. Non-volatile memory, settings saved in protected memory are not lost during power outages. Red LED glows when infrared motion detected and green LED glows when ultrasonic motion detected.
