Installation Guide
Introduction
The 9940 and 9941 keypads are designed to work with 9853, 9851, 9752, 9751
and 9651 alarm system control units. These keypads are a direct replacement for
the 9930, and offers the advantage of smaller size and improved appearance.
The 9940 keypad has a proximity tag reader coil fitted inside the case and can
work with the same proximity tags as the 934 proximity reader module. The 9941
has no detector coil fitted.

Operator Controls and Displays
The 9940 and 9941 keypads have a two line by 16 character LCD display that
shows “first to alarm” information, level status, and programming commands. In
addition there are three LEDs with the following functions:


Glows steadily when mains power is present. Flashes when the system is
working from battery backup.
Glows steadily when the system requires the user to acknowledge an
alert.

Glows steadily if:
a) A fault or tamper circuit is active while the system is unset.
b) The system needs an engineer or remote reset.
c) A telephone line fault is present.
The 9940 keypad provides the following keys:
9 - 0 Used to key in access codes or select programming commands.

Used to enter programming and setting/unsetting commands.

Used to set the system with individual zones (including 24 hour zones)
temporarily omitted.
ABCD Level or partition setting keys
In addition, some control units may support the Dual Key Alarm function to allow
users to start an alarm by pressing the following pairs of keys:
1 + 3 Panic alarm
4 + 6 Medical assistance
7 + 9 Fire alarm

Installation
Cabling Keypads
Cooper Security recommend that you use 8-core 7/0.2 or 16/0.2 alarm cable for
wiring keypads
You can connect the keypads in either a star or bus configuration. If you are
intending to use long cable runs then Cooper Security recommend that you use
star wiring with no more than 200m of cable per branch.
Siting Restrictions (9940 only)
The 9940 keypad contains a coil inside the case that acts as the sensor for
proximity tags used to set and unset alarm systems. The coil works at a low radio
frequency and has a spherical detection pattern of roughly 120mm radius. This
detection sphere can extend through wood, brick, plaster, glass and plastic walls.
Electromagnetic devices, including other 9940 or 9950 keypads, can interfere with
the operation of the coil.
When siting the keypad:
Avoid magnetic devices, for example: electric motors, door releases,
microwave detectors or ovens.
Avoid large metal structures. Remember that screwing a keypad to a metal
frame may significantly alter the detection range
Avoid fitting keypads anywhere near an entryphone, loudspeaker, PA
system, or other proximity reader or security tagging system
Do not put two keypads back to back even if there is a wall between them
If any of these conditions are present, you should test the operation of the keypad
with a prox tag at the proposed site before permanently installing the keypad.
In addition, remember to warn users that holding a mobile phone in the same
hand as a tag may seriously affect the reading performance.

Figure 3. Backplate of 9940/9941 Keypad
Cooper Security recommend that you mount the keypad using M4/M3.5 screws
as follows:
1. Select which cable entry you are going to use and break out the appropriate
plastic sections.
2. Hold the backplate in place against the wall and mark the position of one
fixing hole.
3. Drill and plug the hole, and screw the backplate to the wall. Do not tighten
the screw completely home.
4. Make sure the backplate is level and mark, drill and plug at least two other
fixing holes. Screw the backplate to the wall through the fixing holes.
6. Mount the front of the keypad (containing the keypad pcb) onto the backplate
and make sure that the tamper switch operates.

Keypad Addressing
If you have fitted several keypads to one control unit, then each keypad must be
given a separate “address”. Links LK2 to LK4 set the keypad address, as shown
in Figure 4.

Keypad Backlight
When supplied from the factory the keypad is configured with the backlight OFF.
To turn the keypad backlight ON fit the supplied jumper to both pins of the “ON
BACKLIGHT” link, shown in Figure 4.
Connecting Exit Terminate or Panic Buttons
To connect an exit terminate button use the “ET” connector terminals on the
keypad PCB.
Use the “ET” connector terminals to connect a Lock Switch. If using a lock switch
do not connect any other device to the “ET” terminals.
