SECTION 2 – PLANNING YOUR INSTALLATION
If you are replacing an old Wired Alarm System, it is possible to re-use the existing installed wiring
for the Detector to save installation time. However ensure the cores of these existing cables are at
least 26AWG. When re-using, ensure each pair of cores are correctly marked up when connecting a
detector to the Control Panel unit.
2.1 Location of components
Control Unit – Location
In choosing a suitable location you should bear in mind:
★ The user needs to reach the Control Unit easily within the allocated time, when entering and
leaving the premises.
★ The Control Unit should not be visible from the exterior of the protected premises.
★ All detectors and the external siren must be wired to the Control Unit.
★ The Control Unit needs to be connected to an AC main via a CE approved adapter.
Having chosen the location do not mount at this stage

Movement/Passive Infra Red Detector (PIR) – Location
★
The detector should not be mounted near to large metal objects or on metal surfaces. It needs
to be mounted on a wall or in a corner at a height of approximately 2 to 2.5meters for the best
general coverage in an average room. The detector has been designed to avoid false alarms,
nevertheless, it is best to avoid looking directly at sources of heat such as fires and boilers,
and always try to keep away from a window. A PIR can look at a radiator but should not be
sited above one.
★ Do not site a PIR where its field of view may be obstructed (e.g. by curtains). Also note that
PIRs work best when sensing movement across rather than along their detection beams. You
need to consider the need to wire these units back to the Control Unit.
