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
Fitting
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.
WARNING Ensure that the wall is strong enough
to support the weight of the control unit, its lid and
lead-acid batteries. The total weight of the control
unit plus batteries can be up to 18kg.
The case must be vertical, as shown in Figure 2.
Locate and mark the position of the case. 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 20).
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 19. Fit feet only to the fixing holes that
you intend to use.
Figure 19 Fitting Feet and Tamper Sleeve.
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 point where the tamper
bracket touches the wall. see Figure 20. Fit the
tamper shroud at the position where the lid/back
tamper touches the wall, see Figure 20.
Figure 20 Fitting Tamper Shroud.
Fitting Case Back to Wall
Mount the case vertically, as shown in Figure 20.
Use at least three fixing holes. Use No14/M6
screws at least 50mm long, inserted into wall
anchors appropriate for the type of wall. Figure 2
shows the fixing holes and cable entries.
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.
Protect the unit from dust and drilling debris when
drilling the fixing holes.
Installing the Lid/Back Tamper
Fit and connect the combined lid/back tamper
(provided). Ensure that the switch is oriented as
shown in Figure 21.
