PIR OCCUPANCY SWITCHESThese neat and unobtrusive models are ideal for flush mounting through suspended orplasterboard ceilings. They have a 2m cable, for quick and easy installation.Ceiling flush-mounted PIR occupancy switchOrder code:CEFL PIRSpecificationDetection zone: 360°Time lag range:Photocell range:Loading:Wiring diagram:Dimensions:10 seconds to 40 minutes in 9 steps100 to 1000 lux, and inactiveUp to 6 amps (1500W) of resistive, transformer orfluorescent lighting loads, 2 amps (500W) of lowenergy lighting loads (LED lamps and compactfluorescent) or up to 1 amp (250W) of fans or mostmetal halide lampsSee diagrams 12a and 12b below72mm diameter x 68mmIdeal for false orplasterboardceilingsOrder code:CEFLP PIRSpecial versionsPlug and socket version: CEFLP PIRModel CEFLP PIR is provided with a plug suitable for theCESO Ceiling socket shown on page 17.Loading:Up to 6 amps (1500W) of resistive, transformer orfluorescent lighting loads, 2 amps (500W) of lowenergy lighting loads (LED lamps and compactfluorescent) or up to 1 amp (250W) of fans or mostmetal halide lampsControl pluggedinto a CESO ona BESA boxPIR occupancy switch variantsVariants are available on request such as 24V or 12V (a.c. or d.c.), ideal for low voltagecontrol systems. To special order we can also supply volt free outputs for mains, 24V or12V supplies (including versions with gold contact relays).Detection diagramsPlan view of detection zoneFig. 201 Ceiling mounted PIR occupancy switchPerspective view of detection zoneSeveral PIR occupancy switchesUp to 5mUp to 7mStrong 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.PIR Quad detectorgives 124 detectionareas within the zone.CEFL PIRUp to 5mUp to 7mStrongdetectionzoneSecondarydetectionzoneIn open plan areasFor best coverage the CEFL PIR should be spaced every5m in either directionUp to 5mUp to5mDimensions in mmWiring diagrams66side2m cable6072553plan3872Requires 63 or 64mm (2.5")diameter hole in a falseor plasterboard ceiling12a.
