Note:
On initial installation the PIR Detector should
be set into Walk Test mode ready for testing.
8.
The PIR Detector incorporates a sensitivity feature
designed to compensate for situations where the
Detector may be affected by environmental
changes, (e.g. insects, air temperature, etc). This
feature is called “Detection Sensitivity” and may be
set to Standard or High Sensitivity.
Note:
The higher the sensitivity the less movement
will be necessary before the PIR Detector will
trigger the alarm.
The recommended setting is Standard Sensitivity.
If set to High Sensitivity, in some cases, extreme
environmental problems could cause unattributed
false alarms. If this is experienced it may be
necessary to reset the PIR Detector to Standard
Sensitivity.
Set the required detection sensitivity using DIP 5 of
SW3 as follows:
9.
Connect the PP3 Alkaline battery to the battery clip.
Note: When the 9V Alkaline battery is connected
the LED behind the lens will rapidly flash for
approximately 2-3 minutes until the PIR Detector
has warmed up and stabilized. The LED will then
stop flashing and turn OFF.
10. Check that the PIR Detector PCB is located and set
in the correct position to give the detection zone
pattern required.
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.
11. Refit the PIR Detector to the rear cover by offering
the PIR Detector up to the rear cover and locate the
clips in the top edge into the rear cover. Push the
lower edge of the PIR Detector into place and refit
the fixing screw in the bottom edge of the PIR
Detector to secure in position. Do not over-tighten
the fixing screws as this may damage the casing.
Testing the PIR Detectors
Ensure that the system is in Test mode.
Ensure that the PIR Detector is set in Walk Test mode,
(i.e. DIP 4 of SW3 ON) and mounted in position on the
wall. Allow 2-3 minutes for the PIR Detector to stabilize
before commencing testing.
1.
Put the Control Panel into “Walk Test” mode by
pressing on the Control Panel.
The Panel will beep and the Zone 1 LED will
illuminate.
2.
Walk into and move slowly around the protected
area, each time the PIR Detector senses
movement the LED behind the lens will flash. In
addition, the Control Panel will beep twice to
indicate that the alarm signal has been received
and the appropriate zone LED which the Detector
is set for will illuminate.
Note: In normal operation, the LED will not flash
on movement detection. If necessary re-adjust
the detection pattern by changing the mounting
position of the PCB within the PIR Detector
housing.
3.
Reset the PIR Detector into Normal operation
mode by switching DIP 4 of SW3 to the OFF
position and refit in position.
4.
Press on the Control Panel to exit Walk Test
mode.
Note:
When the PIR Detector is fully installed
i.e. battery cover is refitted; the unit will not detect
movement for approximately 45 seconds after each
activation. (This feature is present to conserve
battery power and maximize the battery life).
