3. Installation
Note: The installation steps listed below assume
that you have already decided on the required
number and location for all keypads, expanders
and power supplies.
Caution: Static Electricity
Like many other electronic products, the control
unit, keypads and expanders contain components
that are sensitive to static electricity. Try not to
handle their PCBs directly. If you must handle a
PCB, take the standard precautions against
damage by static electricity.
Step 1. Fit the Control Unit
Case
Mark Fixing Points and Back Tamper
To prevent access to the inside of the control unit
through the holes in the rear of the case you must
mount the control unit on a wall or other flat
surface.
The case must be vertical, as shown in Figure 2.
Locate and mark the position of at least three
fixing holes. Figure 2 shows the fixing holes and
cable entries.
WARNING
Ensure that the wall is strong enough
to support the weight of the control unit, its lid and
17Ah lead acid battery. The total weight of the
control unit plus batteries can be up to 11kg.
Also, mark the position where the lid/back tamper
bracket touches the wall. There must be enough
space around this point to fit the supplied tamper
shroud (see Figure 21).
Fitting Plastic Feet and Tamper Sleeve
The control unit is supplied from the factory with
four plastic feet and one plastic tamper sleeve. Fit
these onto the outside of the case back, as shown
in Figure 20. Fit feet only to the fixing holes that
you intend to use.
Fitting tamper Shroud
The tamper shroud is intended to prevent an
intruder sliding a tool between case and wall to
interfere with the tamper bracket. When fitted the
shroud must surround the tamper sleeve and the
point where the tamper bracket touches the wall.
see Figure 21
Figure 20 Fitting Feet and Tamper Sleeve.
Figure 21 Fitting Tamper Shroud.
Fitting Case Back to Wall
Use No14/M6 screws at least 50mm long,
inserted into wall anchors appropriate for the type
of wall.
WARNING
Ensure that the fixings are strong
enough to support the weight of the control unit,
its lid and 17Ah lead acid battery. The total weight
of the control unit plus batteries can be up to
11kg.
Protect the unit from dust and drilling debris when
drilling the fixing holes.
Fitting the PCB
The control unit PCB is supplied in a separate
carton designed to store it safely if you wish to fit
the pcb sometime after you have fitted the case.
Clip the plastic PCB carrier into the holes
provided, see Figures 22 to 24.
