WIREFREE PASSIVE INFRA
RED DETECTORS(PIR's)
Two Passive Infra Red Detectors are supplied in the
standard package. However, additional Passive Infra
Red Detectors can be purchased separately, if required.
Passive Infra Red Detectors are designed to detect
movement within a protected area. The Detector
element detects differences in Infra Red radiation when a
person moves within the protected area. If movement is
detected, a radio signal is transmitted to the Control Unit
to activate the alarm.
The recommended position for a Passive Infra Red
Detector is in the corner of a room mounted between 2
and 2.5 metres from the floor. At this height, the detector
will detect movement up to 6 metres at 110° and 12
metres at 60° depending on adjustment. Also, in this
position, the 110°/60° fan-shaped detection patterns can
normally offer greater protection than mounting on a flat
wall. Before selecting a position for a Passive Infra Red
detector the following points should be noted:
1. Do not position Detector facing a window or
direct sunlight. Passive Infra Red Detectors are not
suitable for use in conservatories or draughty areas.
2. Do not position Detector directly above any source
of heat, eg. fire, radiators, boiler etc.
3. Where possible, keep pets out of areas protected
by Passive Infra Red Detectors. If this is not
possible, alternative mounting arrangements or a
special Pet Lens may be required.
4. Where possible, mount the Detector so that the
logical path of an intruder would cut across the fan
patterns rather than directly towards the Detector.
Any number of Passive Infra Red Detectors can be
used with your system, providing they are all coded
with the system House Code and are within the radio
range of the Control Unit. To install and set the
Passive Infra Red Detectors, proceed as follows.
INSTALLING THE WIREFREE PASSIVE
INFRA RED DETECTORS (PIR’s)
1. Remove the battery cover by inserting a coin

2. Remove the screw (in the battery compartment)
holding the wall bracket to the Detector.
3. Slide the bracket up and remove the wall bracket
from the Detector as shown.
4. Hold the wall bracket in position and mark the two
