The Litelume Bi-level PIR Motions Sensor 20 ( MS20 ) is a self-contained motion and daylight sensor with a line voltage relay design. Suitable for installation inside commercial lighting fixtures for indoor or outdoor use. The IP66 outdoor rated MS20 uses passive infrared (PIR) sensing technology to detect motion in its coverage area and automatically dims and/or turns off lights when no occupancy is detected. Intended for mounting heights ranging from 8’ to 40’, offering 2 lens coverage choices and operating 0-10v dimming and/or non-dimming drivers.
