CEFL PIR DSI
CEFL PIR DSI
Ceiling Flush Mounted
Ceiling flush-mounted PIR occupancy switches with closed loop control for DSI ballasts CEFL PIR DSI can be used to control up to 20 high frequency DSI dimmable ballasts. They incorporate a passive infra-red quad sensor to detect movement of a warm body within its detection zone and a photocell to monitor the ambient light level. The products can be flush mounted into suspended and plasterboard ceilings. CEFL PIR DSI operates by Presence Detection. The PIR switch will automatically switch the lights ON when a person enters the room. It will automatically switch the load OFF or to its reduced lux level (minimum) when no further movement is detected for its RUN-ON time.
