Description

The Watt Stopper WS-250-B 120/277 VAC Passive Infrared Wall Switch Sensor offers automatic on and off functions of your lighting based upon movement in a room and the ambient lighting levels present.  The Watt Stopper WS-250-B 120/277 VAC Passive Infrared Wall Switch Sensor is an easy and energy efficient replacement for your standard wall switches and fits in standard decorator wall plates.  The Watt Stopper WS-250-B 120/277 VAC Passive Infrared Wall Switch Sensor is an improved version of the WS-200 and features flying leads, shallower housing and a new control button.

The Watt Stopper WS-250-B 120/277 VAC Passive Infrared Wall Switch Sensor utilizes passive infrared (PIR) technology to detect occupancy.  The Watt Stopper WS-250-B 120/277 VAC Passive Infrared Wall Switch Sensorutilizes the passive infrared technology to determine the difference between the infrared energy of a body in motion and the background space.  The Watt Stopper WS-250-B 120/277 VAC Passive Infrared Wall Switch Sensor will automatically turn your lights on once motion is detected.  Once the sensor no longer detects motion and the time delay has elapsed your lights will automatically shut off.  The Watt Stopper WS-250-B 120/277 VAC Passive Infrared Wall Switch Sensor is capable of being used with line voltage switch for multi-level lighting.  The built-in light level sensor detects natural light and keeps your lights off as long as natural light is available.
