WIRELESS PASSIVE
INFRA RED DETECTOR(S)
One Passive Infra Red Detector is supplied in the
standard RE5000S 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
the 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
1.8m and 2m from the floor. At this height, the
detector will detect movement up to 5m at 180° and
14m at 110°. Also, in this position, the 180°/110° 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 a 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 a 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 may
be required.
4. Where possible, mount the Detector such that
the logical path of an intruder would cut across
the fan patterns rather than directly towards the
Detector to obtain best detector sensitivity.
SETTING THE WIRELESS PASSIVE
INFRA RED DETECTOR(S)
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 radio
range of the Control Unit. To set the Passive Infra
Red Detector, proceed as follows:
