LOS-502SEC-EMA-500 | 120/277V High bay Sensor with Arm

by IR-Tec

IR-Tec LOS-502SEC-EMA-500 is a line voltage switching high bay fixture PIR occupancy sensor with arm extender for 15-30' mounts. The IR-Tec high bay sensor with arm is a member of the TRANS family is a line voltage switching occupancy sensor designed for all-purpose energy efficient lighting control. occupancy sensor employs a cutting edge quad element pyroelectric (passive) infrared sensor to provide omni-directional sensing capability of occupant’s presence and movements. Rotary DIP switches make the sensor setting easier, faster and more accurate than the conventional analog potentiometer. The sensor is designed to operate in the coldest of environments, down to -40°F/°C. The LOS-500 series comes with optional ambient light sensor (ALS) to inhibit the lighting if ambient light levels are higher than required. The adapter arm assembly is designed to provide complete occupancy sensing for automatic lighting control, ease of use, and the simplest installation possible.
