CEFL PIR DALI
CEFL PIR DALI
Ceiling flush mounted controls.
Ceiling flush-mounted PIR occupancy switches with closed loop control for DALI ballasts CEFL PIR DALI can be used to control up to 20 high frequency DALI dimmable ballasts (broadcast). 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 DALI 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.

Loading
Daylight linked dimming with occupancy switching. For controlling DALI dimmable ballasts (broadcast only). The external DALI power supply provided can control up to 40mA, eg. 20 ballasts at 2mA (varies according to make and model of ballasts). For greater numbers of ballasts (64 max.)additional external DALI Power supplies can be purchased (DANLERS order code: DBPSU). These controls can also switch up to 6 amps (1500W) of dimmable fluorescent lamps. 2 amps (500W) of CFL, LED Drivers and LED lamps and fittings.
