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 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.

Mount the case vertically, as shown in

Figure 1. Use all three fixing holes. Use

No8/M4 dome or pan head screws at least

30mm long, inserted into wall anchors

appropriate for the type of wall. Figure 1

shows the fixing holes and cable entries.

Protect the unit from dust and drilling

debris when drilling the fixing holes.

Step 2. Run Bus Cable

Please read “Cabling Requirements on page

8.

Step 3. Fit and Connect

the Keypad(s)

Siting the Keypad(s)

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 cable run from the control

unit will be longer than 100m (see

Cable Configuration and Length).

Note: Do not site two or more keypads

closer than one metre together, otherwise

their prox readers will interfere and be

unable to read tags.

Fitting

Use No8/M4 25mm countersunk screws in

at least three fixing holes when mounting

the back of the keypad on the wall.

Figure 12 Screw Keypad Back Box to Wall

Connection

Figure 13 shows the wiring connections at

the keypad and control unit.

Figure 13 Connecting a Keypad to the Bus

Keypad Addressing

The control unit assigns addresses to all

devices connected to the bus cable. You

must start this process off once all bus

devices are connected, during the initial

power up. See page 20 for instructions.

Backlight Control

You can control the appearance of the

keypad backlights and set/unset LEDs by

fitting links over the appropriate jumpers

on the keypad pcb (see Figure 7 on page 6

for the position of the jumpers).
