Detection Zone Pattern for PCB in position 5
When considering and deciding upon the mounting
position for the detector the following points should
be considered to ensure trouble free operation:
1. Do not position the detector facing a window or
where it is exposed to or facing direct sunlight.
PIR Movement Detectors are not suitable for use
in conservatories.
2. Do not position the detector where it is exposed
to draughts
3. Do not position the detector directly above a
heat source, (e.g. fire, radiator, boiler, etc).
4. Where possible, mount the detector in the
corner of the room so that the logical path of an
intruder would cut across the fan detection
pattern. PIR detectors respond more effectively
to movement across the device than to
movement directly towards it
5. Do not position the detector in a position where
it is subject to excessive vibration
Ensure that the position selected for the PIR
detector is within effective range of the Siren, (refer
to "Testing of Remote Control").
Note: When the system is Armed, household pets
should not be allowed into an area protected by a
PIR Detector as their movement could trigger the
PIR and initiate an alarm.
Note: DO NOT fix the detector to metalwork or
locate the unit within 1m of metalwork (i.e. radiators,
water pipes, etc) as this could affect the radio range
of the Keypad.
INSTALLING THE PIR MOVEMENT
DETECTORS
Ensure that the system is in service mode.
1. Undo and remove the fixing screw from the
bottom edge of the PIR. Carefully pull the
bottom edge of the detector away from the rear
cover and then slide down to release the top
clips.
2. Carefully drill out the required mounting holes in
the rear cover using 3mm drill according to
whether the unit is being mounted in a corner or
against a flat wall.
3. Hold the rear cover in position against the wall
and mark the positions of the fixing holes.
4. Fix the rear cover to the wall using the two
18mm No.4 screws and 25mm wall plugs, (a
5mm hole will be required for the wall plugs). Do
not over-tighten the fixing screws as this may
distort or damage the cover.
5. Configure the PIR detector as described below.
Remember that on initial installation the device
needs to be tested and should therefore be
configured in Walk Test Mode.
6. Check that the detector PCB is located and set
in the correct position to provide the required
detection range.
