Cooper Wiring Devices OS306U-V Motion-Activated Occupancy Sensor Wall Switches use advanced Passive Infrared (PIR) technology to sense the movement of heat-emitting bodies. Occupancy Sensors provide Auto-on/Auto-off or Manual-on/Auto-off operation while Vacancy Sensors provide Manual-on/Auto-off operation. The sensors automatically turn lights off after a space becomes vacant and a preset time delay elapses. Both versions provide single-pole (single-location) and 3-way (multi-location) wiring and work with all lighting load types (INC, MLV, ELV, FLR, CFL, LED). A selectable and dimmable LED nightlight is provided. All sensors are compatible with any decorator-style or decorator screwless wallplate.
