The MPW-L is a wall mounted motion sensor that operates lights using passive infrared (PIR) technology. The motion sensor features a 150° field of view to provide up to 1000 sq.ft. of coverage area. The sensor operates lights based on the occupancy and ambient light levels detected in the area. The sensor turns lights ON automatically when motion is detected, and turn OFF after no motion has been detected for the pre-selected time delay. The motion sensor's time delay can easily be adjusted from 15 seconds to 30 minutes. This device also contains a light level sensor. If adequate daylight is present, the sensor holds the load OFF until light levels drop, even if the area is occupied. The light level and motion sensor sensitivity are also easily adjustable. The motion sensor includes a manual ON/OFF button. This switch is for single pole use only. The MPW-L operates on 24V supplied by MPP-24 power pack (sold separately).
