Please ensure that this device is disconnected from the supply if an insulation test is made. This product is covered by a warranty which extends to 5 years from the date of manufacture.Precautions and Warranty Ceiling Surface PIR absence switch CESFA PIRDANLERS ceiling surface passive infra-red absence switch (CESFA PIR) can be ceiling mounted on a square pattress box (DANLERS code: PABO). The CESFA PIR incorporates a passive infra-red quad sensor to detect movement of a warm body within its detection zone (diagram A) and a photocell to monitor the ambient light level.When entering the room, if the ambient light is dark enough, the lights can be activated by using a momentary light switch. The ambient threshold can be set by the user to between approximately 100 lux and infinite lux (photocell inactive) via the LUX adjuster (diagram B). If no more movement is detected within a pre-selected time, then the CESFA PIR will switch the load off. This time lag can be set via the TIME adjuster to 10 seconds, 20s, 40s, 1 minute 15 seconds, 2m 30s, 5m, 10m, 20m or 40 minutes (diagram B).Pressing the momentary switch again (while CESFA is in its ON state) will overide the control enabling the load to be switched OFF. This is useful when a darkened room is required or if the user does not wish the time lag period to elapse. Allow a minimum of 1 second to elapse between presses of the momentary switch. If pressed before the 1 second has elapsed the control will not switch the load.LoadingThe CESFA PIR can be connected to a 230V (+/-10%) 50Hz (+/-10%) a.c. supplyThey can switch up to 6 amps (1500W) of: • Fluorescent lamps, high frequency or switch start • Incandescent or mains halogen lamps (recommended with integral safety fuse) • Electronic or wire wound transformers.They can also switch up to:• 2 amps (500W) of low energy lamps: CFL, LED, 2D etc. • 1 amp (250W) of metal halide lamps or fans.They have a minimum switching capacity of 2W, suitable for most energy saving lamps, LEDs, contactors and emergency fittings.For larger loads, the CESFA PIR can be used to switch a contactor.16/07/13 INS954 CESFA PIRTroubleshooting The load will not switch on when the momentary switch is operated: • The LUX adjuster is set too low and is inhibiting the switch.The Absence detector switches off when the room is occupied: • The occupation is outside of the detection zone (see diagram A), movements are too small or too infrequent. Increase the TIME adjuster.Installation procedure1. Please read these notes carefully before commencing work. In case of doubt please consult a qualified electrician.2. POSITIONING: The CESFA PIR should be installed to achieve correct coverage of the area, see diagram A. If the photocell override facility is required, the switch must be located above an area where daylight can give greater illumination than the artificial light. Avoid locating this product where it is exposed to windy or drafty conditions (exposed lobbies, open ceiling voids or near ventilation fans) or near heat sources. To cover large areas CESFA PIRs should be spaced in a 5 metre grid formation.3. The greatest energy savings will be made if each CESFA PIR controls an independent set of lamps. They can be wired in parallel but this should ideally be limited to three, see diagram D.4. Make sure the power is isolated from the circuit. The CESFA PIR should be connected as shown in diagrams C & D: L - Live in. N - Neutral in. AB - Absence in. SL - Switched Line out. Start-up modeWhen the CESFA PIR is powered up, it will switch on the load for 1 minute, the load will then switch off and the CESFA PIR will enter its Operating Mode. Time and Lux set-upFor convenience, ensure that the TIME is set to the minimum when setting up the LUX level. Afterwards set the TIME to a value suitable for the application, making reference to diagram B.The LUX is best set up when the local ambient light is at approximately the minimum desired working light level. With the LUX set fully clockwise wait for the CESFA PIR to switch off. Step the LUX adjuster slowly anticlockwise (- to +), at each position operate the momentary wall switch and continuing until the lamps switch on.
