Product Details:

Watt Stopper Passive infrared wall switch occupancy sensor in white color is rated at 120/277 VAC, 50/60 Hz and is designed for loads like 1/6-hp, 0 - 1000/0 - 1200 Watts ballast, LED. It provides 180-degree coverage up to maximum of 900 ft for extraordinary performance. Sensor has a custom two-tier Fresnel lens for precise coverage and has a zero crossing circuitry for reducing stress on the relay and results in increased sensor life. It has neutral terminals that are exposed with the help of optional neutral connection with break off tab. It can be used with line voltage switches for multi-level lighting and has a time delay adjustable from 30 seconds - 30 minutes. It covers major motion up to 35 ft x 30 ft and minor motion up to 20 ft x 15 ft. It includes a button for positive tactile feedback.

Sensor turns lights OFF/ON based on occupancy and fits behind a standard decorator wall plate. It is factory set for 30-minute time delay, maximum light level and sensitivity. Time delay elapses and lights automatically turn OFF when a place is evacuated making it energy saving. Walk-through mode turns lights OFF, three minutes after the room is initially occupied if no motion is detected after the first 30 seconds. Sensor is suitable for retrofit projects and suits small/enclosed spaces and finds application in small offices/conference rooms and utility/break rooms. The sensor is enclosed in a durable shallow 1-Inch plastic housing and has flying leads for easy installation. Light level sensor holds lights off when ambient lighting is above the preset level. It offers patented voltage drop protection. Sensor has LED to indicate occupancy detection. It measures 2.680 Inch x 1.750 Inch x 1.040 Inch. Sensor is UL/cUL listed.
