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 monitored by the control
unit. You also need to assess where any radio
expanders must be placed in order to receive
radio signals from their detectors successfully.
Radio Site Survey
If you intend to fit radio expanders, you should
conduct signal strength tests.
Eaton’s Security
Business produce the Scantronic 790r hand-held
signal-strength meter and 734r-01 test transmitter
for this purpose. Please read the 790r manual for
details.
Please be aware of the following:
The 790r signal-strength meter readings
should be used only as an guide when initially
checking the site.
A reading of four green LEDs or higher
indicates an acceptable signal strength.
Once you have installed the alarm system,
you should put the control unit in the Installer
test menu and test the received signal
strength from each radio transmitter.
A signal strength reading of two or more units
by the control unit from each transmitter
should provide reliable operation in the
installed system. (Note: if you take the signal
strength using
Eaton’s Security Business
Downloader or the web browser interface
while the panel is in user mode, the minimum
acceptable signal strength is four units.
Ensure that the control unit is in Installer
mode when reading signal strengths
remotely.)
When you record the signal-strength readings
for later inspection, you should record the
readings taken from the control unit of the
installed system while it is in the Installer
menu.
Please be aware that the signal strength received
from a transmitter can change after installation
because of local environmental changes. For
example, users switching on laptops nearby, or
moving metal cabinets from their original position
can all affect the signal from a transmitter. Please
read
Eaton’s Security Business publication
”Guidance Notes for Wireless Alarm System
Installations” obtainable from
www.coopersecurity.co.uk for more information
about the factors affecting radio signal strength.
Siting the Control Unit and Wired Zone
Expanders
WARNING Ensure that the fixings are strong
enough to support the weight of the control unit,
its lid and two 17Ah lead-acid batteries. The total
weight of the control unit plus batteries can be up
to 18kg.
Do site the unit:
Upright, batteries at the bottom. (This does
not apply to the wired zone expander.)
Within a protected area.
Do NOT site the unit:
In the entry or exit areas, or outside the area
covered by the alarm system.
Next to electronic equipment, particularly
computers, photocopiers or other radio
equipment, CAT 5 data lines or industrial
mains equipment.
Siting Keypads
Do site the keypad(s):
Within the area protected by the alarm
system.
At a convenient height and location for the
user.
Out of sight of potential intruders.
Do NOT site the keypad(s):
Next to electronic equipment, particularly
computers, photocopiers or other radio
equipment, CAT 5 data lines or industrial
mains equipment.
Where the length of cable run from the control
unit or an EXP-PSU will reduce the voltage at
the keypad below 10.5V (see Cable
Configuration and Length).
Note: Do not fit any keypad with a prox reader
closer than one meter to any other type of prox
reader. This includes other keypads with prox
readers, external prox readers such as the KEY-
EP, or prox readers used by other systems (for
example access control systems). If you mount
prox readers closer together than one meter
(including on the other side of walls) then the two
prox readers will interfere and may not work
correctly.
Siting Wireless Zone Expanders
Do site the unit:
Upright.
Within a protected area.
As high as possible. However, do make sure
that the unit is on a similar level to the
transmitters or receivers.
More than 10m from another radio expander.
