SYSTEM
KEYPAD FUNCTIONS
Many of the functions in the PC4020 have limited access
so that only certain users may have control of special
functions. The installer can program the 2nd Master
Code to enable it and have access to the entire panel's
operations the same as the Grand Master.
• System Master Code users can have access to all end-
user options.
• Supervisory Code users can have access to options
related to their partition.
• All other types of users have options available to them
for their partitions.
All of the above mentioned keypad functions are listed
in the following pages.
Introduction
The LCD4500 remote keypad provides complete
information and control of the PC4020 control panel.
• The panel can be fully programmed from any keypad.
• The LCD display provides alarm and status indication
for the alarm circuits as well as guiding the user in
operating the system.
• The built-in buzzer lets the user hear correct key entries
and other alert signals.
• The 12 digit keypad is used for code entry and other
programming functions. All keypad entries are made by
pressing one key at a time.
The keypad is normally in the arm-disarm mode. In this
condition, the LCD message indicates the status of the
system. The "Enter Code to Arm System" message
comes on when all zones are closed. The system can
be directed to perform other functions such as zone
bypassing, displaying trouble conditions, displaying
alarm memory and programming by entering one of the
various [✱] commands described below. Pressing the
[#] key or not making any key entry for 2 minutes always
returns the keypad to the arm-disarm mode.
Partitions
The PC4020 can have up to 128 zones. These zones
can be divided by the installer into 8 separate partitions,
that can be armed and disarmed separately. Zones can
be assigned to more than one partition. Keypads can be
individually assigned as a global keypad or to a specific
partition. More than one keypad can be global, or can
be assigned to each partition. User codes can be
enabled to work on one or multiple partitions in the
access code partition mask. System Master codes can
arm and disarm any partition from any keypad. The
default setting for the PC4020 has only partition 1
enabled with zones 1 to 16 assigned to it. To enable
more partitions, enter the Partition Area menu of the
Installer's Programming section, and select to add/edit
the partition to be enabled.
Access Codes
An access code is a 4 or 6 digit (optional) number which
will permit access to the system, i.e. Arm/Disarm
control, Installer's Programming etc. User access codes
are programmed in the User Programming section
[✱][5]. The default access code is '1234' for 4 digit option,
and '123456' for 6 digit option. See 'User Programming
Commands' for details on programming access codes.
Global Keypads
What is a Global Keypad?
A global keypad is a keypad which belongs to all partitions
and may be accessed by all users on the system with valid
access codes. The keypad will prompt the user to select
the partition to edit, the keypad is then "loaned" to the
partition selected by the user. The user can only access
partitions which his/her code is assigned to.
Why should a Global Keypad be used?
Global keypads allow the entire system to be controlled by
one keypad. This is beneficial if the keypad is to be located
in a central area, for example, the lobby of an office
building where the zones are common to all partitions and
each office contains individual zones.
How to create a Global Keypad?
The global keypad may be any keypad on the system. The
first keypad on the system is enrolled as a Partition 1
keypad. It may be made into a global keypad by selecting
the option, "KYPD #1 Global" found in the system toggle
options of Installers Mode. If multiple partitions are enabled
on the system this will assign the keypad to all active
partitions.
When the next keypad is enrolled onto the system the
keypad will prompt with the message "Select (01) <>",
options 01 - 08 are the usual partition assignments, the last
option (09) is "Global Keypad".
How to use a Global Keypad?
The default message displayed on the keypad is "Enter
Your Access Code", or the clock display if the option is
enabled. From this state any user entering a valid access
code may access the system.
The global keypad will display message
ENTER YOUR
ACCESS CODE
or will be the clock display if the option is enabled. From
this state any user with a valid access code may access the
system. The system can be directed to perform functions
such as arming/disarming and all [✱] mode functions. No
function can be performed without first entering a valid
access code.
• Single Partition
If a single partition access code is entered the user will
be prompted with the message
SELECT (0)
< >
ARM PARTITION
R
if the partition is already disarmed. The lower right hand
corner of the display will show the partition status using
the letter R for Ready, and N for Not ready.
To arm the partition press [✱] or [0] the message
EXIT DELAY
IN PROGRESS...
