Battery-powered, passive infrared (PIR) sensors that automatically control lights via RF communication to compatible dimming or switching devices. These sensors detect the heat from people moving within an area to determine when the space is occupied. The sensors then wirelessly transmit the appropriate commands to the associated dimming or switching devices to turn the lights on or off automatically. They combine both convenience and exceptional energy savings along with ease of installation. Has 2 settings available: auto-on/auto-off, and manual-on/auto-off. PIR motion detection with exclusive Lutron XCT Technology for fine motion detection. 180 degree field of view: 1500ft2 (139.4m2) minor motion, 3000'2 (278.7m2) major motion. Hallway model with long, narrow field of view: major motion coverage of up to 150' (45.7m). Simple and intuitive adjustments available for timeout, activity, and auto-on settings. Accessible test buttons make setup easy. Lens illuminates during test mode to verify ideal locations. Multiple sensors can be added for extended coverage. 10-year battery life design. For use with compatible Lutron RF devices only. Communicates to various wireless Lutron Clear Connect systems.
