Introduction
The LCD4500 keypad provides easy to understand English language
information about the status of your security system and makes daily
operation simple by prompting the user through each operation.
The keypad provides audible feedback each time a key is pressed and with
unique audible sequences it signals troubles and the correct or incorrect
entry of information.
About Your Security System
Your DSC security equipment has been designed to give you the greatest
possible flexibility and convenience. The LCD4500 keypad will guide you
through each operation with English language prompts. Read this manual
carefully and have your installer instruct you on system operation and on
which features have been implemented on your system. All users of this
system should be equally instructed in its use.
FIRE DETECTION
This equipment is capable of monitoring fire detection devices such as
smoke detectors and providing a warning alarm if a fire condition is
detected. Good fire detection depends on having adequate numbers of fire
detectors placed in appropriate locations. This equipment should be
installed in accordance with N.F.P.A. standard #74 (N.F.P.A. Batterymarch
Park, Quincey MA 02269). Carefully review the Family Escape Planning
guidelines in this manual.
Note: Your installer must enable the fire detection portion of this
equipment before it becomes functional.
✎ Important Note
A security system cannot prevent emergencies. It is only intended to alert you and, if
included,amonitoringstationofanemergencysituation.Securitysystemsare
generally very reliable but they may not work under all conditions and they are not a
substitute for prudent security practices or life and property insurance. Your security
systemshouldbeinstalledandservicedbyqualifiedsecurityprofessionalswho
should instruct you on the level of protection that has been provided and on system
operation.
MONITORING
This system is capable of transmitting alarms, troubles, and emergency
information over telephone lines to a monitoring station. If you inadvertently
initiate an alarm, immediately call the monitoring station to prevent an
unnecessary response.
Note: The monitoring function must be enabled by the installer before it
becomes functional.

GENERAL SYSTEM OPERATION
Your security system is made up of a PC4020 and one or more LCD4500
and various detectors and sensors. The DSC control panel will be mounted
out of the way in a utility room or basement. The metal cabinet contains the
system electronics, fuses and stand-by battery. There is normally no reason
for anyone but the installer or service person to have access to the control
panel. The LCD4500 keypads have an audible indicator, an alphanumeric
LCD, (Liquid Crystal Display), and command entry keys. The keypad is used
to send commands to the system and to display the current system status.
The keypad(s) will be mounted in convenient locations inside the protected
premises close to the exit-entry doors.
The security system has several zones or areas of protection and each of
these zones will have one or more detection sensors connected to it (motion
detectors, glassbreak detectors, door contacts or shock sensors).
Keypad LED Displays
READY LIGHT (LCD45X1 KEYPADS ONLY)
If the Ready light is ON, the partition is ready for arming.
If the Ready light is OFF, check to see that all doors and windows are
closed and that all movement is stopped in areas covered by motion
detectors. The partition cannot be armed unless the Ready light is ON
indicating that all zones are closed and the partition is in the Ready state.
ARMED LIGHT
If the Armed light is ON, the partition has been armed successfully.
TROUBLE LIGHT
If the Trouble light is ON, check to see what the trouble condition is and call
for service.
System Master Menu Functions
System Master Codes may perform any function for any partition on the
system except changing or deleting the System Grand Master Code.
The System Master Menu can be accessed by entering [System Master
Code] [9]. Use the [<] [>] keys to display the items of the System Master
Menu. Press [✱] to select an item:
[0]View Event Buffer [1]Set System Time [2]Set System Date
[3]Enable DLS Window [4]System Reset [5]Previous Menu
[0] View Event Buffer - This function allows any Master Code to review the
Event Buffer on the keypad display. The first line of the display will show
the event number and the partition on which the event occurred; the
second line of the display will show the date and time of the event. Press
the [✱] key to display a description of the event. Use the [<] [>] keys to
scroll through the list of events in the Event Buffer.
[1] Set System Time programs the system’s 24 hour clock. Enter 4 digits in
24 hour time to set the clock, the first 2 digits are the hour, the last 2
digits are the minutes. For example, to program 2:35 pm, type in 1435.

4
[2] Set System Date programs the system’s calendar. Enter 6 digits, the
first two digits are the month, the middle 2 digits are the day, and the last
two digits are the year. For example, to program February 14, 1992 type
021492.
[3] Enable DLS Window - The end user can enable ring detect for 60
minutes to allow a computer to call the panel. The installer can disable
this function in the DLS section of the installer’s programming.
[4] System Reset - A System Reset turns off the power to the COMBUS for 5
seconds and resets the main panel. No programming will be lost and the
time will not have to be reprogrammed. A system reset should be done if
there is a COMBUS Communications fault or an Internal fault.
[5] Previous Menu - If the user decides to do nothing, either select this
option, or press the [#] key to return to the arm/disarm state.
Partition Status Enunciator
If the partition status enunciator is enabled, the status of all active partitions
will be displayed on the keypad.

Global Keypads
WHAT IS A GLOBAL KEYPAD?
A global keypad is a keypad which belongs to all partitions. It can be
accessed by all system users who have a valid access code with the global
access attribute enabled. The keypad will prompt the user to arm or disarm
their partition(s). The global keypad can also be “loaned” to a partition by
selecting options from the global menu then selecting the desired partition.
The users can only access partitions which are assigned to their codes.
HOW TO USE A GLOBAL KEYPAD?
The Global Keypad will display the message

or the full system status will be displayed if the global system status option is
enabled, or the clock will be displayed if global clock display is enabled. From
this state any user entering a valid access code with the global access attribute
enabled on their 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.

Display of Alarms/Bypassed Zones
Your installer may enable bypassed zones or zones in alarm to be viewed
on armed partitions. If so, pressing the [<] [>] keys will display any zones on
the partition that have gone into alarm with the message “View Alarms”
followed by the zone label. Any zones on the partition which were manually
bypassed may also be viewed by pressing the [<] [>] keys.
Note that Home-Away zones which are normally bypassed upon arming the
system will not be displayed.
Auto-bypass/Home-Away Arming
If a correct access code is entered and you do not exit the premises
through a designated exit-entry door, the system will, at the end of the Exit
delay time, arm with interior zones automatically bypassed if those interior
zones have been programmed as “Home-Away” zones. These zones will
remain bypassed until a delay zone is tripped or [✱] [1] is entered to
reactivate bypassed home-away zones.
This is a convenience feature for someone who wishes to remain on the
premises with the system armed. That person does not have to manually
bypass the home-away zones.
If partitions are remotely armed using a global or multi partition access code
i.e. a code that can arm/disarm partitions 1, 2 and 3. The home-away zones
will be active on those partitions except the one being armed from if the user
does not exit through a delay zone.
To reactivate the Home-Away zones that have been automatically bypassed,
press [✱] [1]. This command is a quick method of fully arming the system in
residential applications.

Partition Keypads
KEYPAD ZONES
All Fire, Auxiliary and Panic keys are only functional if they have been
programmed by the installer. The installer should indicate which of these
keys are active by placing a coloured label next to the key.
• Fire - Holding [F] key
or both keys down for 2 seconds will sound a fire
alarm. The alarm will sound pulsing and a transmission will be sent to the
monitoring station. The keypad will sound three beeps once the panel has
accepted the alarm.
• Auxiliary - Holding [A] key
or both keys down for 2 seconds will send
a transmission to the monitoring station.
• Panic - Holding [P] key or both keys down for 2 seconds will send a
transmission to the monitoring station. The installer can program this key
to sound the alarm or to transmit the alarm silently.
The global keypad will always send (if programmed) the system area
account code. The Fire, Auxiliary and Panic keys will activate for all active
partitions. Any valid access code from any partition may silence the alarm.
ARMING
Close all protected doors and windows and stop movement in areas
covered by motion detectors.
The “Enter Code to Arm System” message should be on the LCD display.
The system cannot be armed unless the “Enter Code to Arm System” or
“Secure System or Enter Code...” message is displayed.
If Double EOL resistors are being used, 3 different messages can be displayed
when viewing open zones, Zone Open, Zone Tamper and Zone Fault. Zone Open
will be displayed if the zone is in the alarm state, Zone Fault will be displayed if
the zone is shorted, and Zone Tamper will be displayed if the zone is open.
Enter a 4 digit or 6 digit access code. As each digit is entered the keypad
will beep.
• If the access code was entered incorrectly, the keypad will beep steadily
for 2 seconds.
• If the code was entered correctly but the system was not secure due to an
open zone, the keypad will beep quickly followed by a steady tone.
• When the correct code is entered, the “Exit delay in Progress” message
will be displayed and the keypad will beep three times quickly. If a
System Master Code was entered, the system master menu will appear.
See “System Master Codes”.
A timer will appear in the right side of the display indicating the remaining
time in the exit delay. Exit the premises through the designated exit-entry
door. When the allowed exit time expired the message on the keypad will
change to “Enter Code to Disarm System”.

and enter the code again. The “Armed” light will go out and the keypad
buzzer will stop. The correct access code must be entered before the
allowed entry time expires. To change the entry time see “Installers
Programming Command”, [✱][8]. If an alarm occurred while the panel
was armed, the “View Memory” message will be on the display with the
zone label for the zone that caused the alarm. The display will keep
those messages on for two minutes or until the [#] key is pressed to
return the panel to the normal arm-disarm mode.

USER PROGRAMMING COMMANDS
[✱]+[5]+[ACCESS CODE]
The [✱][5][Access Code] command is used to program the Master Codes
and regular access codes.
The first access code is the System Grand Master Code. Normally, only the
installer can change the System Grand Master Code. The installer may also
program the system to allow the user to change the System Grand Master Code.
The System Grand Master Code has no limitations to its use. It may be used
to create or delete other System Master Codes or to perform any user
function on the system. Note that only to the first access code can be the
System Grand Master Code.
Note: When using a global keypad the System Master should assign
access codes to avoid duplication.
Each access code may be programmed as one or a combination of the
following options:
••
••
•System Master CodesSystem Master Codes
System Master CodesSystem Master Codes
System Master Codes may perform any function for any partition on the
system except change or delete the System Grand Master Code, or
change or delete other System Master Codes.
••
••
•Supervisory Codes allow the user to program and edit other access
codes, except System Master and Duress Codes, for any partitions which
the access codes belong to. Supervisory Codes are also used for arming,
disarming, bypassing and all other functions that a System Master Code is
capable of.
••
••
•Arm Only Code allows the user to arm only the partitions to which the
code is assigned.
••
••
•Disarm Only Code allows the user to disarm only the partitions to which
the code is assigned.
••
••
•Door Strike Code allows the user to operate door strikes only within the
partition to which the code is assigned. (The PC4020 has not been
investigated to the requirements of UL294.)
••
••
•Duress Codes are used to disarm partitions and send a duress code
transmission to the monitoring station. A user would enter a Duress Code to
indicate that they are being forced by an intruder to disarm the system.
When a Duress Code is entered, the partition or partitions to which it is
assigned will disarm normally, and a Duress Code transmission will be sent
to the monitoring station. Also, any outputs programmed as “Duress
Outputs” will be activated when the Duress Code is entered. A Duress Code
may be programmed for arming and disarming; note that the “Duress Code”
will be transmitted to the monitoring station for any event it performs.

14
• One-Time Use Codes are used to allow infrequent users of the system,
such as service personnel, to arm the system. When the system is armed
using a One-Time Use Code, the code will be erased once the Exit Delay
expires; after this time, the code may not be used again. If the One-Time
Use Code is entered before the Exit Delay expires, arming of the system
will be cancelled; the One-Time Use Code may then be entered again
later to arm the system.
• Log Only Codes are used strictly for logging to the event buffer. The
system master can log the time, date and location which they were at with
the Log Only codes. To enable this code type, enable just door strike or
disable all options.
Note: Do not program access codes such as 1111 or 1234 which can
be easily guessed and will compromise the security of your system.
• Escort 4580 Access allows the user to access the Escort 4580 (Voice
Prompting Module) via the in house telephone or remotely through a
telephone. The user will have the same abilities through the VPM-2 as they
would through a regular keypad.
Note: Do not program One-Time Use Codes without arming or disarming
enabled.
• Global Access allows the access code to be used on global keypads.
Disabling this toggle option for any access code will inhibit the code from
being used on any global keypad.
• Partition Selection Menu brings up the partition selection menu when a
multi-partition access code is entered on a partition keypad. When this
option is disabled, multi-partition access codes will function as a single
partition access code for the partitions the access code is enabled on.

15
PROGRAMMING ADDITIONAL ACCESS CODES USING A SYSTEM
MASTER CODE OR A SUPERVISORY CODE
1Press [✱] then [5] to enter the User Programming Commands; the
keypad will display the message “Enter Your Access Code”. Any System
Master Code or Program Code may be entered.
• If the Grand Master Code is entered, System Master Codes and
regular access codes for any partition will be able to be programmed.
• If a System Master Code is entered, regular access codes for any
partition will be able to be programmed. A System Master Code can
also create Supervisory and Duress Codes.
• If a Supervisory Code is entered, only access codes belonging to the
partition to which the Supervisory Code is assigned may be changed.
When a valid access code is entered, the keypad will display the number
of available access codes on the first line of the screen.
2The keypad will display the message “Sel Code (xxx) < >”. “(xxx)”
represents the number of the access code that has been selected for
programming and the access code name on the second line. Use the [<]
[>] keys to scroll through the list of access codes, or enter the code
number 001 to 128. When the desired access code number is displayed,
press the [✱] key to program the code.
3When an access code is selected for editing by pressing the [✱] key, a
menu for editing access codes will be displayed. Select one of the menu
items by entering a number on the keypad.
[0] Program Code - When [0] is pressed, the keypad will display the
message “Enter Digits” and the presently-programmed access code.
Enter the new 4 digit or 6 digit access code. Do not press [✱] or [#]
while entering the access code. If you do not wish to change the
code, press [#] key.
[1] Erase Code - If an access code is no longer needed, this selection
will erase the code, but not the user’s name.
[2] Edit Access Code Name - When a PC4400 RS232 module is enrolled
on the system, the name of the code which is used to arm and disarm
will be printed out. Also, the access code name helps keep track of the
code when programming codes. Move the cursor to left or right by
pressing the [<][>] keys. The letters of the alphabet have been divided
up among the 1 to 9 number keys on the keypad as below:
[1] = A, B, C, 1 [2] = D, E, F, 2 [3] = G, H, I, 3
[4] = J, K, L, 4 [5] = M, N, O, 5 [6] = P, Q, R, 6
[7] = S, T, U, 7 [8] = V, W, X, 8 [9] = Y, Z, 9, 0
[0] = Space

16
For example, if you press the [4] key once, the letter ‘J’ will appear
above the cursor on the display. Press the [4] key again, the next
letter ‘K’ will appear, and so on. If a different number key is pressed,
e.g. the [6] key, the cursor will automatically move to the right one
space, i.e. the letter ‘P’. To erase a character, use the [<] [>] keys to
move the cursor under the character, then press the [0] key.
While programming the access code label, press the [✱] key to call
up an options menu. To select an option, press the corresponding
number key or scroll through the options using the [<][>] keys, then
press the [✱] key to select.
[0] Clear Display will clear the entire code label.
[1] Clear to End will clear the display from the character where the
cursor was located to the end of the display.
[2] Change Case will toggle the letter entry between upper case letters
(ABC...) and lower case letters (abc...).
[3] ASCII Entry
(see Appendix A) is for entering uncommon characters.
There are 255 characters, but 000 to 031 are not used. Use the [<][>]
keys to toggle through the characters or enter a 3 digit number from 032
to 255. Press the [✱] key to enter the character into the code label.
[3] Edit Access Code Options - When [3] is pressed, the keypad will
display the message “Select toggle < >”. Use the [<] [>] keys to
scroll through the list of options:
• System Master? • Bypass? • 4580 Access?
• Program Codes? • Door Strike? • Global Access?
• Arm? • Duress Pulse? • Partition Selection
• Disarm? • One Time Use? Menu?
[4] Edit Partition Mask - The Partition Mask is used to assign the access
code to one or more partitions. In order for an access code to
function, the Partition Mask must be assigned to the access code;
if
no partition mask is assigned, the code will not operate on any
partition.
[5] To Exit the menu, press the [#] key.
4To exit the Access Code Programming Mode, press [#].

17
ZONE BYPASSING
[✱]+[1]
A bypassed zone will not cause an alarm. If a zone is bypassed the panel
may be armed even if the zone is open. Use zone bypassing when access
is needed to part of the protected area. Also, damaged wiring or contacts
on a zone may be temporarily bypassed until repairs can be made so that
the panel can be armed.
To bypass zones, enter [✱] [1]. An access code may be required if the
installer has enabled that option. A menu will appear.
[0] Bypass Zones - This selection takes you immediately to bypassing
zones. Use the [<] [>] to select the zones to be bypassed and press the [✱]
key to select the zone. A “✱” will appear beside the zone label to indicate
the zone will be bypassed when the partition is armed.
A zone search routine allows the user to find the desired zone to bypass by
entering in the first letter of the zone to search for, and pressing one of the
[<][>] keys. The [>] key will search for the first zone on the partition that
begins with the letter selected. Pressing the [>] key again will search for the
next zone on the partition that begins with the letter selected.
The letters of the alphabet have been divided up among the 1-9 number
keys on the keypad.

CLEAR
[1] Clear Bypasses will remove bypasses from all the zones in your partition
and then takes you to bypassing zones. None of the zones will have a “✱”
beside them.
[2] Recall Bypasses will bypass all the same zones selected for the last
time zone bypassing. This is for users who always bypass the same zones.
[3] Previous Menu takes the user back to the “Enter Code to Arm System”.
When the PC4020 is programmed, the ability to bypass certain zones may
have been eliminated by the installer. In this case, the “✱” message for
those zones will not come on in response to the bypass command. Zone
bypasses are automatically cancelled when the panel is disarmed.
Note: At no time can any armed zone be bypassed.

18
While the system is disarmed, bypassing can be used to temporarily silence
the door chime feature on a zone. Simply bypass the zone that the door
chime feature enabled. The keypad will no longer beep when the zone is
opened. Be sure to clear all bypasses before arming, to ensure no zones
are unintentionally bypassed.
TROUBLE DISPLAY
[✱]+[2]
The PC4020 continuously monitors a number of possible trouble conditions.
If one of these conditions occurs, the keypad “TROUBLE” indicator will light
and the audible indication will sound (two short beeps every 10 seconds).
When the [#] key is pressed the audible indication will stop on that partition,
but the trouble indicator light will remain ON until the trouble is cleared.
Trouble conditions can also be transmitted to the monitoring station. Press
the [✱] then [2] keys to display the trouble conditions.

Press [#] to return to “READY”.
Battery Trouble
- A battery trouble will be displayed and can be reported if
thebattery is 11.3 volts or less, disconnected or the battery fuse fails. Battery
voltage is checked once every 4 minutes, so the battery trouble may not
restore instantly when the battery is restored. Initiating a bell/comm test will
check the battery voltage. When DC Inhibit Arm is enabled the panel will
check the condition of the batteries on the system (main panel and PC4204)
when an access code is entered. If during this check the battery shows a
low voltage condition the arming will be inhibited. The LCD will display the
message "Fail To Arm... Battery Trouble" when this occurs.
The Control panel and each of the PC4204 modules may only have 3 battery
trouble alarms in a 24 hour period. After the third battery trouble for a given
module the trouble condition will "Shutdown" until midnight of that day. The
trouble will still be enunciated with the keypad Trouble LED but the event will
not be logged to the event buffer or be communicated.
AC Trouble
- There is no audible annunciation on AC power failure. The
system “Trouble” light will come ON but the audible indication will not sound
until there is a low battery condition. Transmission delay can be
programmed for 000 to 255 minutes.

19
Aux Supply Troub - An Aux trouble is generated if the aux fuse on the main
panel opens, or if the Aux or SW Aux terminals are overloaded.
TLM Trouble -
A telephone line trouble is generated when the line voltage
drops below 3 volts for more than 30 seconds. A keypad trouble is
generated when the system is disarmed and if selected, a local alarm
sounds when the panel is armed.
TLM TBL Line #1 - When using the PC4700 Fire Module a telephone line trouble
is generated when the line voltage drops below 3 volts for more than 30 seconds
on line one. A keypad trouble is generated when the system is disarmed and if
selected, a local alarm sounds when the panel is armed.
TLM TBL Line #2 - When using the PC4700 Fire Module a telephone line
trouble is generated when the line voltage drops below 3 volts for more than
30 seconds on line two. A keypad trouble is generated when the system is
disarmed and if selected, a local alarm sounds when the panel is armed.
FTC Trouble -
If the digital communicator is unsuccessful in communicating with
the monitoring station after 10 attempts, a Fail to Communicate trouble is
generated. If a later attempt to communicate is successful the trouble is cleared.
Bell CCT Trouble -
If the bell fuse opens or the bell circuit is open, a
keypad trouble and a Bell Circuit trouble transmission are generated.
Fire Trouble -
If a FIRE loop is open circuit, a keypad trouble and a Fire
Loop trouble transmission are generated. A trouble on the FIRE loop will
unconditionally initiate an audible and visual (trouble light) indication on the
keypad. This means that even if any other previous trouble has been
silenced, a FIRE loop trouble will restart the keypad buzzer.
Fire Trouble 2WS - If the fire zone on a PC4700 Fire Module is opened, a
visual keypad trouble (trouble LED will come on) with audible indication and
a fire zone trouble transmission is generated. The LCD will show the
message "FIRE TROUBLE!! 2 Wire Smoke", until the fire zone trouble is
restored. If there is more than one PC4700 trouble condition present these
trouble messages will scroll every 3 seconds to the next message.
Loss of Time -
When the PC4020 is powered up, the internal time of day
clock needs to be set to the correct time. This trouble is cleared when an
attempt is made to reset the internal time of day clock. See “System Master
Codes” for resetting the time of day clock.
Module Com Fault -
The panel has lost communications with a module and
cannot recover it. Check to see if the module is connected properly, then do
a system reset. See “Diagnostics” in the Programming Manual to determine
which module is not communicating.

20
COMBUS Low Pwr
- Modules are not getting enough voltage from the
COMBUS. Check for proper connection of COMBUS, or the COMBUS needs
to be repowered. See 4204 modules and the 4204 PGM COMBUS power
option for supplying voltage to the COMBUS. See “Diagnostics” in the
Programming Manual to determine which module has low voltage.
Internal Fault
- A problem has occurred with the COMBUS microprocessors. If
this trouble occurs, check connections to the COMBUS and do a system reset.
4204 Battery TBL
- If any PC4204 relay output module’s battery drops
below 11.3 volts, a battery trouble is generated.
To determine which of the PC4204’s has the low battery, check the reporting
code transmitted to the monitoring station or check the event buffer printout
if there is a printer attached, or through downloading. The battery voltage is
checked once every 4 minutes. So the battery trouble may not restore
instantly when the battery voltage is restored.
4204 AC Trouble
- If any PC4204 relay output module loses incoming AC power,
the keypad trouble light will indicate a 4204 AC trouble. But there will be no
audible annunciation until there is also a low battery condition.
The PC4204 AC troubles will be transmitted to the monitoring station immediately.
4204 AUX Trouble
- If the Aux fuse on any PC4204 relay module should
open or if the Aux supply is overloaded, a 4204 Aux trouble is generated.
Ground Fault - A Ground Fault trouble condition will occur if the Earth Ground
(EGND) connection is shorted to a positive voltage source or shorted to a
non-earth ground potential. This trouble will generate an audible and visual
trouble as well as a Ground Fault reporting code transmission.
Waterflow TBL - If the Waterflow zone on a PC4700 Fire Module is opened
(WFA or WFB), a visual keypad trouble (trouble LED will come on) with
audible indication and a Waterflow trouble transmission is generated. The
LCD will show the message "FIRE TROUBLE!! Waterflow TBL", until the
Waterflow zone trouble is restored. If there is more than one PC4700 trouble
condition present these trouble messages will scroll every 3 seconds to the
next message.
Cellular Trouble -
This indicates that the LINKS unit has one or more of the
following trouble conditions: AC, battery, loss of cellular or a tamper fault.
DLS Fault TBL - This trouble condition will generate an audible and visual
trouble when the control panel fails to complete communications with the
downloading computer.
Zn Sensor Fault - This trouble condition will occur when a wireless zone
fails to report a zone supervisory. To view which zone has the trouble press
the [✱] key while viewing the trouble condition. The zone(s) with the trouble
condition will be displayed in numerical order on the display. A keypad
trouble is generated when the system is disarmed and a visual "Zn Sensor
Fault" trouble and trouble reporting code will be transmitted.
