Battery-powered passive infrared (PIR) sensor that automatically controls lights via RF communication to compatible dimming and switching devices. This sensor detects the heat from people moving within an area to determine when the space is occupied. The sensor then wirelessly transmits the appropriate commands to the associated dimming and switching devices to turn the lights on or off automatically. Combines both convenience and exceptional energy savings potential along with ease of installation. Has 3 settings available: auto-on/auto-off, auto-on low-light/auto-off, and manual-on/auto-off. Auto-on low-light feature will turn lights on automatically only if there is less than approximately 10 Lux (1 fc) of ambient light. Uses Clear Connect technology. PIR motion detection with exclusive Lutron XCT Technology for fine motion detection. 360 degree coverage from 324'2 (30.2m2) to 676'2 (62.4m2), depending on mounting height. Simple and intuitive adjustments available for timeout, auto-on, and activity settings. Supports advanced occupancy features such as dependent occupancy groups and customizable occupied/unoccupied presets in some systems. Multiple sensors can be added for extended coverage. Lens illuminates during test mode to verify ideal locations. Multiple ceiling-mount methods available for different ceiling materials. Front accessible test buttons make programming easy. 10-year battery life design.
