Chapter 2: Planning the Installation
Choosing the installation locations
When planning the installation, consider the following recommendations concerning the
locations of where to install the control unit and other devices.
Control unit
The control unit must be located:
Within the protected area (but not in an entry or exit zone).
Upright (battery at the bottom for all except i-on Compact) on a wall or other flat
surface to discourage tamper attempts from the rear.
Out of sight of potential intruders.
Ideally, more than 2 metres from the floor.
Where maximum cable distances will not be exceeded (see page 24).
Radio devices
Carry out a radio survey using the DET-RSURV01 Survey Tool to confirm that there will be
sufficient signal strength between the planned location of radio devices and the control unit
or radio expanders.
Do not locate any radio device, control unit (with built-in radio capability), or radio
expander:
Near to any source of electromagnetic or radio interference.
Within 1 metre of high-voltage cables, metal pipes, computers, photocopiers, or other
electrical or electronic equipment.
In a location where maximum radio range will be exceeded.
In a metal enclosure or close to large metal structures.
Keypads and proximity readers
Keypads and proximity readers should be located at a convenient height.
Keypads must be within the area protected by the intrusion system and ideally out of sight
of potential intruders.
Proximity readers or any keypad containing a proximity reader must not be located:
Within 1 metre of another proximity reader (including one located within another
keypad).
Behind a door, coat rack or other covering.
