PIR OCCUPANCY SWITCHES WITH DIMMINGBrings lights on – only when area is occupied. Automatically dims lights accordingto ambient light level to maintain constant brightness of between 100 and 1000 lux(adjustable). Adjustable time lag before switching off. For suspended or plasterboardceilings. Complete with 2m cables for quick and easy installation.PIR occupancy switch with daylight linked dimmingCEFL PIRDD 10VDC is suitable for dimmable ballasts with 1-10VDC input.Order code:CEFL PIRDD 10VDCSpecificationDetection zone: 360°Time lag range: 10 seconds to 40 minutes in 9 stepsPhotocell range: 100 to 1000 lux, falling on the working planeLoading:Total load of ballast, lamps plus other load not more than 6 amps includingfluorescent.Can control up to 20mA, eg. 20 ballasts at 1mA.(Varies according to make and model of ballasts)Wiring diagram: See diagram 26 belowDimensions:72mm diameter x 68mmEnough daylight, Occupied– Lighting OFFReduced daylight, Occupied– Lighting DIMMEDNight, Occupied– Lighting ONEnough daylight, Unoccupied– Lighting OFFReduced daylight,Unoccupied – Lighting OFFNight, Unoccupied– Lighting OFFDetection diagramsPlan Plan view view of detection of detection zone zonePerspective view Perspective of detection viewzoneof detection zoneCovering large areasStrong detection zone i.e. personmoving armSecondary detection zone i.e. personwalking (less sensitive when walkingstraight towards PIR switch)For optimum coveragerecommended mountingheight between 2.4 and 5m.CEFL PIRDD 10VDCStrongdetectionzoneSecondarydetectionzoneTo cover large areas it is advisableto install one CEFL PHDD 10VDCto dim and a few CEFL PIR to switch.Up to 5mUp to 7mPIR Quad detectorgives 124 detectionareas within the zone.Up to 5mUp to 7mDimensions in mmWiring diagramsideplan26.
