Location planning
Operating range
All devices must be within 30 metres of the siren
unit and must not be mounted on or near large
metal objects. Avoid obvious sources of electrical
interference such as fridges and microwave ovens.
Tamper switches
When mounting devices ensure that any tamper
switches close fully. On uneven surfaces it may be
necessary to place packing behind the switch for
reliable operation.

Work out the best places to locate the devices for maximum protection. Having chosen the
locations do not mount at this stage.
Smoke detector
• Mount in the middle of the ceiling at the top of
a stairwell, or on the centre of hallway ceilings
where smoke would most likely be detected.
• Do not mount in corners or above cooking
appliances and heaters.
• Install additional detectors if there are closed
doors preventing smoke from reaching
detectors.
Help button accessory
The help button provides extra protection for you
and your family. When help is needed the button
can activate your alarm immediately - even when
the system is disarmed.
• Mount on bedroom wall or by the front door
• Not clearly visible to an intruder
• Easily accessible
• Out of reach of children
• Not outdoors
PIR movement detectors
• Mount in a position such that an intruder would normally
move across a PIRs field of view.
• Height should be between 1.7 and 2.3 metres above floor
level.
• Location in a corner will ensure wider room coverage.
• Do not mount a PIR where its field of view will be
obstructed e.g. by curtains, ornaments etc.
• Do not point directly at sources of heat e.g. fires or boilers,
and do not position directly above radiators.
• Avoid mounting a PIR directly facing a window.
• Do not point a PIR at a door protected by a door/window
contact.
