Description

The Watt Stopper WS-250-G 120/277 VAC Passive Infrared Wall Switch Sensor provides automatic on and automatic off functions for your lighting loads based upon occupancy and ambient lighting present within the room.  The Watt Stopper WS-250-G 120/277 VAC Passive Infrared Wall Switch Sensor is an energy efficient replacement for your standard wall switches and fits into standard decorator wall plates.  The Watt Stopper WS-250-G 120/277 VAC Passive Infrared Wall Switch Sensor is an upgraded version of the WS-200 that features a new control button, flying leads and a shallower housing.

The Watt Stopper WS-250-G 120/277 VAC Passive Infrared Wall Switch Sensor uses passive infrared (PIR) technology to sense movement within a room.  The Watt Stopper WS-250-G 120/277 VAC Passive Infrared Wall Switch Sensor uses PIR technology to distinguish between a body in motion and the background space.  The Watt Stopper WS-250-G 120/277 VAC Passive Infrared Wall Switch Sensor automatically turns your lights on once motion is detected and ample natural light is not available.  Once the Watt Stopper WS-250-G 120/277 VAC Passive Infrared Wall Switch Sensor no longer detects occupancy and the time delay has expired the lighting will automatically shut off.  The Watt Stopper WS-250-G 120/277 VAC Passive Infrared Wall Switch Sensor is capable of being coupled with line voltage switches for multi-level lighting.  The built-in light level sensor that is featured in the Watt Stopper WS-250-G 120/277 VAC Passive Infrared Wall Switch Sensor keeps your lights off as long as natural light is available.

The Watt Stopper WS-250-G 120/277 VAC Passive Infrared Wall Switch Sensor is great for break rooms, utility rooms, conference rooms and offices.  The Watt Stopper WS-250-G 120/277 VAC Passive Infrared Wall Switch Sensor aids in energy saving and can help you conserve up to 60%  on your energy usage within the room it is installed.  The Watt Stopper WS-250-G 120/277 VAC Passive Infrared Wall Switch Sensor is backed by a five year manufacturer warranty and is UL and cUL listed.
