INSTALLING THE PIR DETECTORS
(Ensure that the system is in Test 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 mountingholes in the rear cover
using 3mm drill according to whether the unit is being mounted
in a corner or against a flat wall.
Note:
Using 1st mounting hole to fulfill corner mounting installation,
while 2nd mounting hole for flat wall installation.
3. Using the rear cover as a template, mark the positions of the
fixing holes on the wall.
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 that the device needs to be tested and
should therefore be set in Walk Test Mode.
6. Check that the detector PCB is located and set in the correct
position to provide the required detection range. To adjust the
PCB position, simply slide it up or down ensuring that the
location legs are aligned with the required position number
marked on the board.
7. To refit the PIR detector to the rear cover and locate the clips in
the top edge into the rear cover. Push the lower edge of the
detector into place and refit the fixing screw in the bottom
edgeof the PIR to secure in position. Do not over-tighten the
fixing screws as this may damage the casing.
SETTING THE PIR DETECTORS
Located on the PCB of the PIR Detector is a two-position DIP switch (SW2). When conducting the Walk
Test, ensure that the DIP switch SW2 is set as follows:
1. DIP1 of SW2 is used to configure the PIR Detector for walk test mode, which allows the operation of
the detector to be checked during installation without triggering a Full Alarm.
ON
Walk Test mode
OFF
Normal mode
