If you need extended motion sensing range, a longer timed duration, higher power handling, or the highest possible quality and reliability in a motion sensing light switch, choose this Ivory Leviton Commerical Grade Wall Occupancy Sensor. This is a switch produced for the demanding requirements of offices and commercial buildings.
Push-button Manual Override Control
For manual control, the wall sensor features a convenient push-button switch. If the lights are OFF, pressing the button will turn lights ON and keep them ON for as long as the room is occupied. The lights will be turned OFF once the room is vacant, after the delayed-OFF time expires. If the lights are ON, pressing the button will turn lights OFF and keep them OFF even if the room is occupied.
Field of View
The wall sensor provides a 180 field of view with a maximum coverage area of approximately 2100 square feet. The maximum sensing distance in front of the sensor is 40 feet, and at each side is 30 feet. A "small-motion" zone detects relatively small body movements and allows the lights to stay ON even though a person may not be moving or walking around the room. The remainder of the field of view, the "large-motion" zone, exhibits a lesser degree of sensitivity and requires larger movements. Integral sliding blinders on each side of the lens may be used to restrict the 180 field of view down to 32. This will prevent unwanted detection in areas such as hallways. Reducing the coverage range allows the unit to ignore motion at the far end of its range and avoid unnecessarily switching lights ON. The range can be adjusted from 100% to 36% of the total coverage area.
A choice of four delayed-OFF time settings is available: 30-seconds (for walking test purposes only), 10 minutes, 20 minutes, and 30 minutes.
To maximize energy savings in some installations, the ambient light override feature will prevent the wall sensor from switching lights ON when there is ample natural sunlight, regardless of occupancy. This adjustment should be made when the ambient light is at the level where no artificial light is needed. Adjustable Ambient Light Override ranges from approximately 2 foot-candles (2 lux) to 500+ foot-candles (500+ lux.). Wall plate sold separately.
Also available in white.
