WS-250 Passive infrared (PIR) Wall Switch Sensor

Passive Infrared (PIR) Wall Switch Sensor turns lighting on and off based onoccupancy and ambient light level. It replaces existing wall switches and fits behind a standard
decorator wall plate. It utilizes advanced PIR technology to detect occupancy. Detection occurs when the it senses the difference between infrared energy from a human body in motion and the background space. Lighting automatically turns on when occupancy is detected. After a user-specified length of time when no occupancy is detected, lighting automatically switches off. The sensor can also be used with line voltage switches for multilevel lighting.Compatible with all electronic ballasts. Available in white, light almond, ivory, gray and black. It comes with a 5 year warranty.
