The nES 7 is a small passive infrared occupancy sensor designed to be easily embedded into luminaires. This sensor provides excellent line of sight 360 PIR detection of small motion and walking motion. The nES 7 is ideal for small rooms without obstructions or areas with primarily walking motion (e.g. corridors, library stacks). Additionally, anoptional integrated photocell enables daylight harvesting control as well. Typically one or more nES 7 sensors are paired with either a nEPP5 D linear relay pack(s) or nLight enabed relay pack(s) or panel.For rooms like classrooms and private offices or any space with obstructions, the nES PDT 7 dual technology sensor is recommend.
