The PIR Detector adopts a 1/2 AA size 3.6V Lithium
battery which under normal conditions will have typical
life in excess of 4 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
upon detecting movement. When this occurs the
batteries should be replaced as soon as possible.
CHOOSING A MOUNTING LOCATION
The PIR Detector is suitable for mounting in dry interior
locations only.
The recommended position for a PIR Detector is in the
corner of a room mounted at a height between 1.8 and
2m. At this height, the detector will have a maximum
range of up to 10m with a field of view of 110
̓
, subject
to the position for the PCB being set in 5. 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 7m
approximately, with position 1 providing a range of 5m
approximately. The recommended position setting for
the PCB is 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 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 Smart
Home Box.
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.
