The ENERLITES MDL-V is a dual-technology wall mounted motion sensor that operates lights using a combination of passive infrared (PIR) and ultrasonic technologies. The motion sensor features a 150° field of view to provide up to 1000 sq.ft. of PIR coverage area and 800 sq.ft. of ultrasonic 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 sensors time delay can easily be adjusted from 15 seconds to 30 minutes. A "walk-through" mode can turn lights off after only 3 minutes, if no activity is detected after 30 seconds following an occupancy detection. This sensor 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 device includes a manual ON/OFF button. This switch is for single pole use only.
