INSTRUCTION MANUALINSTRUCTION MANUALPIR Recessed White89431POSITIONING THE UNITWhen selecting the mounting position, please take the following points into account:1. The sensor is designed for optimum performance to be mounted in house ceiling (see Figure 2)2. Don’t pointing at or positioning close to heat sources such as heater or heat extraction units, which may causefalse triggering.3. If you set Lux control level to dark ( ), do not pointing sensor at bright light since unit will not act.4. Don’t mounting at strong electromagnetic disturbance environment where false triggering may be caused.FITTING THE UNITBefore any electrical work, ensure mains supply cables are isolated by switching off and removing the relevantfuse. (See Figure 1)1. Drill a circle hole of around 2.5-inch (63.5mm) diameter in the ceiling where your are to mount the sensor2. Remove the terminal cover ① and unscrew the wire holder ②(see Figure 1)3. Connect the main power wires and loading wires to the copper terminalsMax 4.5MFigure 1Black(Load)Blue(Load)Max 4.5MFigure 2Detection AreaRadiusHouse Ceiling360°12Blue (Mainpower Neutral)Brown (Mainpower Activel)L N Lout ininout LNL2.8 M4. Fix the wires by re-screwing the wire holder’s screw. Fix the terminal cover back5. Press the side springs up, hold them and mount the sensor into the ceiling hole (see Figure 3)After finishing the fitting operation, you can adjust the detection area and working state of PIR sensorOPERTATION MODE:WALK TESTING:When power is switched on to the 89431, the 89431 sensor will enter into a “WARN-UP” period for about 30seconds (within 1 minute) and then automatically change into “AUTO MODE”. While sensor is in the AUTOMODE, you can then carry out a Walk-Test by placing the LUX control to day position ( ) and the TIME control tominimum ( - ). Once the 89431 sensor receives a valid trigger signal (such as movement of a human body) withinits detection area, the lamp(s) (load) will be turned on for the pre-set period of time. You will be ableto determine the detection area by walking slowly.Please be noted that movement across the scan area is more effective than movement directlytoward or away from the sensor. (Refer Fig.4A). If movement is towards or away from the sensor,not across, the detection range will reduce. (Refer Fig. 4B)Ø 76 mmØ 61 mm75 mm220~240V50Hz
