Manual-On Occupancy Sensor 1800W@120VAC INC, 1800VA@120 VAC FL, 1/2 HP, 60Hz, for single pole or 3-way applications when used with IPP0R or VZ0SR, , 180 Degree, 900 Sq. Ft. Coverage, Decora® Passive Infrared Wall Switch- Black, California Title 24 2005 Compliant Leviton offers many products that will help lower electrical costs and add convenience to everyday living. By simply replacing standard switches with occupancy sensors reduces energy consumption and extends bulb life. Leviton's Decora Manual-On Occupancy Sensor Switch complies with California Title 24 by requiring the user to manually turn the lights ON but will automatically turn the lights OFF when a space is unoccupied. It ensures that lights are not left ON unnecessarily for hours at a time. It uses "passive infrared technology" in order to detect human presence in a room, and respond to the infrared heat people naturally emit to monitor a specific area. When this "heat" is sensed, the lights will stay ON in the room, and then turn the lights OFF, when the space is vacated or are unoccupied. Compatible with Decora screwless snap-on wallplates (sold separately).
