IR-Tec LOS-502SEC is a line voltage switching high bay occupancy sensor for 15-30' mounts in 120-277 volt applications. The LOS-500 series is designed for all-purpose energy efficient lighting control. This high bay 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 IR-Tec high bay 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 LOS-500 is designed to provide complete occupancy sensing for automatic lighting control, ease of use, and the simplest installation possible.
