From the manufacturer: DESCRIPTION: The Passive Infrared (PIR) Wall Switch Sensor turns lighting on and off based on occupancy and ambient light level. It replaces existing wall switches and fits behind a standard decorator wall plate. OPERATION: The Passive Infrared (PIR) Wall Switch Sensor utilizes advanced PIR technology to detect occupancy. Detection occurs when the Wall Switch Sensor senses the difference between infrared energy from a human body in motion and the background space. Lighting automatically turns on when occupancy is detected. After a user-specified length of time when no occupancy is detected, lighting automatically switches off. The sensor can also be used with line voltage switches for multilevel lighting. FEATURES:
Custom two-tier Fresnel lens enhances detection at the desktop level • Sensor coverage tested to NEMA Guide Publication WD 7-2000 • Patented voltage drop protection • For safety, there is no leakage to load in the off mode and sensor is safety grounded • LED indicates occupancy detection • Compatible with decorator wall plates • Qualifies for ARRA-funded public works projects• Pulse Count Processing eliminates false offs without reducing sensitivity • Detection Signature Processing eliminates false triggers; provides immunity to RFI and EMI • Zero crossing circuitry reduces stress on the relay and results in increased sensor life • Time delay adjustment from 30 seconds up to 30 minutes 
Adjustable unit sensitivity from 20% to 100% • Light level sensor holds lights off when ambient lighting is above the preset level Applications: The Wall Switch Sensor has the flexibility to work in a variety of applications including offices, conference rooms, break rooms and utility rooms. Energy savings for these areas can be as high as 60% since lighting will no longer remain on once the room is vacant. With a competitive price, low installation cost, and high energy savings, paybacks are usually well under two years. Light Level Sensor: The Wall Switch Sensor features a built-in light level sensor. This feature holds lighting systems off when natural light levels are above the preset level. Once lights are switched on, the sensor will not switch them off even if daylight levels increase. Using the light level feature is optional and the setting is adjustable by the user. SPECIFICATIONS:
120/277VAC, 60Hz, or 347VAC, 60Hz • Time delay adjustable from 30 seconds up to 30 minutes • Adjustable unit sensitivity from 20% to 100% • Adjustable light level setting of 2 to 200 footcandles (21.5 to 2,153 lux) • Compatible with all electronic ballasts and PL lamp ballasts • Coverage: Major motion 35’ x 30’ Minor motion 20’ x 15’ • Dimensions: 2.6” x 1.7” x 1.55” (66.0mm x 43.1mm x 39.4mm) L x W x D • UL and cUL listed
