the Control Panel acknowledges the signal from
the
Remote Control each time the ‘DISARM’ button is
pressed.

PASSIVE INFRARED DETECTORS
PIR detectors are designed to detect movement in a
protected area by detecting changes in infra-red
radiation levels caused, for example, when a person
moves within or across the devices field of vision. If
movement is detected an alarm signal will be emitted,
(if the system and alarm zone is armed).
Note: PIR detectors will also detect animals, so ensure
that pets are not permitted access to areas fitted with
Passive Infra-Red Detectors when the system is
armed.
Any number of PIR Detectors can be used with your
system, providing they are all coded with the system
house code and are mounted within effective radio
range of the Control Panel.
The PIR Detector adopts a PP3 Alkaline battery which
under normal conditions will have typical life in excess
of 2 years. When the battery level drops, with the PIR
in normal mode and the battery cover fitted, the LED
behind the detection window will flash. When this
occurs the batteries should be replaced as soon as
possible.
CHOOSING A MOUNTING LOCATION
The recommended position for a PIR Detector is in the
corner of a room mounted at a height between 2 and
2.5m. At this height, the detector will have a
maximum range of up to 12m with a field of view of 110
°. The position of the PCB inside the PIR can be set to
5 different positions to adjust the range of the detector.
Setting the PCB in position 3 will reduce the range to
9m approximately, with position 1 providing a range of
6m approximately. The recommended position
setting for the PCB is in position 5.
PCB Position Range
1 6m
3 9m
5 12m
Note: The range as indicated above refers to the
linear distance in front of the PIR sensor.
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 locate the detector facing a window or
where it is exposed to or facing direct sunlight.
PIR Detectors are not suitable for use in
conservatories.
2. Do not locate the detector where it is exposed to
ventilators.
3. Do not locate 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.
Less Sensitive More Sensitive
5. Do not locate the detector in a position where it is
subject to excessive vibration.
6. Ensure that the position selected for the PIR
detector is within effective range of the Control
Panel, (refer to ‘Testing the Control Panel &
Remote Control’).
