The Lutron® Maestro® Occupancy sensing switch combines a Maestro® switch with a passive infrared occupancy or vacancy sensor. The sensor detects the heat from occupants moving within an area to determine whether the space is occupied. Based on the feedback from the sensor, the occupancy sensing switch will adjust the load accordingly.FEATURES:Passive infrared sensors with exclusive Lutrone XCTMTechnology for fine motion detection180° sensor field-of-viewUp to 30 ft x 30 ft (9 m x 9 m) [900 ft2 (81 m major motion coverage and 20 ft x 20 ft (6 mx 6 m) [400 ft (36 m)] minor motion coverage Occupancy version can be set to Auto-ON / Auto-OFF or Manual-ON / Auto-OFFVacancy version available to meet CA Title 24 requirements Adjustable timeout (1, 5, 15, or 30 minutes) and high/low sensitivity adjustment Occupancy sensing switch loads: incandescent, halogen, ELV, MLV, CFL, LED, magnetic fluorescent, electronic fluorescent, and fan.
