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 a 17Ah lead acid
battery. The total weight of the control unit
plus batteries can be up to 12kg.
Do site the unit:
Upright, battery at the bottom. (This
does not apply to the wired zone
expander.)
Within a protected zone.
Do NOT site the unit:
In the entry or exit zones, 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
If fitting two or more keypads with internal
proximity card readers make sure that you
place the keypads more than one metre
apart from each other. (At less than one
meter separation the proximity tag readers
in each keypad will interfere with each
other.) Remember not to place keypads on
opposite sides of the same wall.
Siting Wireless Zone Expanders
Do site the unit:
Upright.
Within a protected zone.
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.
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.
Guided Tour
CAUTION: All printed circuit boards for the
control unit, its expanders and keypads
have been tested for Electromagnetic
Compatibility (EMC). However, when
handling the PCBs you must take the
standard precautions for handling static
sensitive devices.
Opening the Control Unit Case
To gain access to the interior of the control
unit undo the screw at the bottom of the
lid. Slide the lid vertically up, then swing
the bottom of the lid out before moving the
lid down and away from the case.
Figure 1 Opening the Control Unit.
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.
