Wattstopper Ci-355 Passive Infrared Line Voltage Ceiling Occupancy Sensor 360 Degree; White

WattStopper�s CI-355 passive infrared (PIR) occupancy sensor automatically turns lighting on and off based on occupancy. The sensor mounts on theceiling with a flat, low-profile appearance and provides 360 degrees of coverage. The CI-355 is line voltage and operates at 120, 230, 277 or 347 VAC. The sensor uses passive infrared technology (PIR) to sense occupancy and automatically turn lighting on. PIR works by sensing the difference between infrared energy from a human body in motion and the background space. When no occupancy is detected for the length of the time delay, lighting automatically turns off. The CI-355 works well in open office spaces, computer rooms, conference rooms, classrooms, and warehouses. It is a good choice for areas with high ceilings or with two-level lighting and can be mounted though tile ceiling or through Octagonal J-Box.. The convenient mounting system keeps installation costs down. It also eliminates the need for a power pack by using line voltage wiring.
