The LCD5501Z32-900 package includes the following
parts:

• One LCD5501Z32-900 keypad

• Four mounting screws

• One keypad inner door label

• One set of Fire, Auxiliary and Panic key labels

You should mount the keypad where it is accessible
to designated points of entry and exit. Once you
have selected a dry and secure location, perform
the following steps to mount the keypad:

1. Remove the keypad backplate by loosening the

screw located at the base of the unit.

2. Secure the keypad backplate to the wall in the

desired location. Use the screws provided.

3. Before attaching the keypad to its backplate,

complete the keypad wiring as described in the
next section.

1. Before beginning to wire the unit, ensure that all

power (AC transfor mer and battery) is
disconnected from the control panel.

2. Connect the four Keybus wires from the control

panel (red, black, yellow and green) to the keypad
terminals (R B Y G). Consult the diagram below:

Installation

3. You can connect a device - such as a door contact

- to the “Z” terminal of the LCD5501Z32-900. This
eliminates the need to run wires back to the control
panel for the device. To connect the zone, run
one wire from the device to the Z terminal and the
other wire from the device to the B (black) terminal.
For powered devices, run the red wire to the R
(positive) terminal and the black wire to the B
(negative) terminal. When using end of line
supervision, connect the zone according to one
of the configurations outlined in your system’s
Installation Manual.

Once all wiring is complete, apply power to the
control panel:

1. Connect the battery leads to the battery.

2. Connect the AC transformer.

specifications, see the control panel 

Installation

Manual.

NOTE:  Do not connect the power until all wiring is
complete.

Once all wiring is complete, you will need to enter a
2-digit number that tells the system the partition
and slot assignment of the keypad.

If your system has partitions, you will need to also
assign the keypad to a partition (1st digit).

The slot assignment (2nd digit) tells the panel
which keypad slots are occupied. The panel can
then generate a fault when a keypad supervisory
signal is not present. There are eight available slots
for keypads. LCD5501Z32-900 keypads are always
assigned to slot 1 by default. You will need to
assign each keypad to its own slot (1 to 8).
