LUTRON LOS-CDT-500-WH LOS-CDT series Occupancy Sensor Dual Technology, Presence Detector 20 - 24 VDC, 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. Rugged, high-impact, injection-molded plastic. Suited for complex environments that are difficult to control with single-technology sensors. Snap-locks to ceiling-mounted cover plate. 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.
