Before You Begin; Preparation; Siting The Unit; Guided Tour - Cooper Security i-on 40 Installation Manual

2. Before You Begin

Preparation

Before installation you should carry out a
survey of the site. You need to know how
many and what kind of detectors will be
transmitting to the control unit. You also
need to assess where the control unit must
be placed in order to receive radio signals
from the detectors successfully.
To do this you should conduct signal
strength tests. Cooper Security produce the
Scantronic 790r hand held signal strength
meter for this purpose. Alternatively, you
can power the control unit from a battery
and use its built-in testing facility to
measure the signal strength from a
detector that you temporarily place at each
planned location.

Siting the Unit

Do site the unit:
Upright (battery at the bottom).
Within a protected zone.
As high as possible. However, do make
sure that the unit is on a similar level to
the other transmitters or receivers.
Do NOT site the unit:
In the entry or exit zones, or outside
the area covered by the alarm system.
Close to or on large metal structures.
Closer than one metre to mains wiring,
metal water or gas pipes, or other metal
surfaces.
Lower than two metres from the floor
(ideally).
Inside metal enclosures.
Next to electronic equipment,
particularly computers, photocopiers or
other radio equipment, CAT 5 data lines
or industrial mains equipment.
Note: Some window glasses, especially
those sold as "insulating" or "energy
conserving" may be coated with thin metal
or conducting films. These glasses are
particularly poor at transmitting radio
waves.
If fitting two or more keypads make sure
that you do not place the keypads within
one metre to each other. (The proximity
tag readers in each keypad will interfere
with each other.) Remember not to place
keypads on opposite sides of the same wall.

Opening the Control Unit Case

To gain access to the interior of the control
unit undo the two screws at the top of the
case. Pull the top of the lid down, and then
lift the lid out of the retaining lugs at the
bottom of the case.

WARNING: When connected to the mains
with power applied mains voltages are
present on the shrouded heads of the
terminal screws of the mains connector ("8"
