for the best general coverage in an average
room. The detector has been designed to
avoid false alarms, nevertheless, it is best to
avoid sitting the unit where it is looking
directly at sources of heat such as fires and
boilers and always try to avoid looking
directly at the window. A PIR can look at a
radiator but should not be sited above one.
z
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 a
movement across rather than along their
detection beams.
z
Do not locate a PIR in the Exit Zone i.e.
between the Control Unit and the final exit
door. In this situation, the PIR will activate
the alarm, once set, when you attempt to
leave the property. However, if this cannot
be avoided, an Engineer code can designate
“Walk Through” zones to cover the
eventuality.
In addition to the 16 radio zones, your system is
equipped with 4 wired zones and 4 two-wire
zones. These are included to give ultimate
protection by allowing a mixture of radio and
wired technologies to be used. The wired Zone 1
is an additional Entry/Exit Zone and we
recommend that you use this zone with a
two-wire PIR to protect the area in which your
Control Unit is located.
Having chosen the location, do not mount at this
stage.
2.2 Planning the location for the system
components
Example of a domestic layout
The layout is intended as a guide only but
demonstrates one example of how a house can be
protected with the system.
The PIR has been placed downstairs to protect
valuables in a chosen room – in this case to
protect the TV, video and hi-fi in the lounge. The
Door/Window Contact Detector has been
positioned to protect the front door.
The example follows the guidelines as stated for
each individual component, but there are
situations where additional accessories may be
required to meet your exact needs.
2.3 Allowing for pets
The PIR senses moving body heat. In some cases
the movement of pets may also be detected. To
overcome this it is recommended that the pets are
kept in one specific room out of sight of a PIR
when the system is armed. If required, additional
Door/Window Contact Detectors (available as
accessories) can then be used to protect the doors
and windows of the room (see section 8 –
Extending the System)
