MX 20 GJD103 Quad PIR Movement Detector -1- Package Contents • 1 x MX20 • 2 x Shutters • 3 x 27mm wall plugs • 3 x 27mm screws • 3 x Tamper Feet • 1 x Tamper Cup • 1 x Installation manual • 1 x Opening Tool • 1 x Lens Mask INTRODUCTION The MX20 is an attractively styled, 20 metre Passive Infrared (PIR) detector, with advanced features such as dual tamper switches for case and wall-mount tamper detection, sensor mounted white-light filter and zone blanking using vertical curtain shutters and horizontal masking for precise area coverage. QUICK INSTALLATION 1. Mount and connect the detector following the instructions given later in this manual. 2. Configure programming switches as required referring to instructions given later in this manual. 3. Apply supply voltage to the unit. The detection LED flashes once. 4. Wait approximately 2 to 3 minutes to allow the detector to settle NOTE: The front cover must be fitted when walk testing. The default settings are: • Range: 20 metres • Pulse Count: 1 (always set to 1 during walk rest) • Detection LED: On (recommend for set up process) MOUNTING THE UNIT During the installation, protect the electronics against water, as trapped moisture can affect or damage the unit. 1.Drill the wall to accept the two fixing screws, the cable entry and the tamper cup (if used) Note: We recommend using the tamper cup on uneven wall surfaces. 2. Remove the cover assembly by loosening the locking screw and using the opening tool provided. The cover hinges from the top and lifts out of the location slot. 3. Feed the cables into the cable entry and Screw the unit to the wall ensuring that the tamper pin is correctly located and that the tamper microswitch is closed. Three spare tamper feet of different lengths are provided to aid installation, The tamper foot is a push fit and can be removed by carefully pulling it from the pin. 4. Connect the cables to the screw-terminal block on the back of the detectors PCB ( see figure 1) 5. When the detector is aligned, connected and programmed to suit the installation, replace the front cover and lock in place. MULTI BEAM ALIGNMENT & MASKING The multifunction lens fitted to MX20 produces 5 long range beams and 5 medium to short range curtain PIR beams (see Figure 2). The PIR circuitry detects changes in heat and movement in the beam pattern; therefore items such as trees, shrubs, ponds, boiler flues and animals should be considered when positioning the detector. NOTE: The PIR sensor is more sensitive to movement across the beams and less sensitive to movement directly towards or away from the beams. The detector module is fitted with two sliding shutters to reduce the detection angle. When coverage exceeds the desired detection area, adjust the module as required and mask off any beams, either vertically or horizontally, to avoid unwanted detection Use portions of the self-adhesive silver mask applied to the rear, smooth side of the lens as shown in Figure 2. Always replace the lens the correct way up to ensure exact beam pattern coverage. When mounted at heights above 3 metres there could be a significant reduction in the range of detection and the target will have to move a greater distance within the field of view before an alarm is generated. Masking Configurations for Maximum Range (see figure 5) Black area should be masked for pet alley applications up to 20 metres Figure 6 shows the pattern for the maximum range in the optimum position (see Figure 4). Figures 7 and 8 illustrates alignment recommendations for when the detector is mounted close to a wall. The alignment shown in Figure 7 is not recommended. If the detector module is orientated at an angle of 90° to the perimeter, the mounting wall may cut off short and medium range beams. The long range beam will still detect an intruder, however the wall can cause false alarms when heated by sunlight. Figure 8 shows the recommend alignment. The detector module is orientated at a 55° angle to the perimeter, As a result, short and medium range beams are parallel to the perimeter, but the detection range along the perimeter is reduced.
