LEGRAND - WATTSTOPPER
The WS-250 Passive infrared (PIR) wall switch sensor turns lighting on and off based on occupancy and ambient light level. It replaces existing wall switches and fits behind a standard decorator wall plate. Light level sensor holds lights off when ambient lighting is above the preset level. Time delay adjusts from 30 seconds up to 30 minutes. Sensor can be used with line voltage switches for multilevel lighting.
