FEATURES
Keypad Programming
The PC2550 comes with a default program so it is operational
with a minimum of programming. It is completely
programmable from the keypad. The panel uses EEPROM
memory so that all information is retained even if the panel
loses both AC and battery power.
Multiple Level Static/Lightning
Protection
The PC2550 has been carefully designed and tested to
provide reliable service. It is built to take static and lightning
induced surges and keep on working. Multiple level surge
filters are on all zone inputs, the power supply, the keypad
connections, the bell output, the auxiliary power supply and
the telephone interface. A special “ZAP-TRAC” circuit
board configuration catches high voltage impulses right at
the wiring terminals. Protective ground planes surround
sensitive areas preventing the spread of damaging voltage
surges. Metal Oxide Varistors (MOV’s) are placed in all the
critical areas to further reduce impulses to safe levels.
“WATCHDOG MONITOR” Circuit
Even when all precautions are taken so that voltage surges
do not cause damage to the control panel, it is possible to
cause temporary disruption to the operation of the
microprocessor causing it to lose track of the program
sequence. The PC2550 is equipped with an external
“Watchdog Monitor” circuit which continually checks the
microprocessor program execution.
System Supervision Features
The PC2550 continuously monitors a number of possible
trouble conditions including:
• An active battery supervision circuit that periodically tests
the battery under load.
• A loss of the AC power supply.
• A supervised fire circuit trouble condition.
• A telephone line monitoring circuit.
• A bell circuit failure indicates open circuit or fuse failure.
• A test code feature which transmits a communicator test
code to the monitoring station at a selected time
everyday. The test code can be sent at intervals from 1 to
99 days.
• A bell/siren/communicator test feature which can be
activated from the keypad.
• TLM (Telephone Line Monitoring) restoral transmission.
Advanced Features
The PC2550 has many advanced features. Features which
provide the security system design flexibility and selling
advantage necessary to win those demanding jobs and
make them profitable.
Some of these features include
• EEPROM memory retains all data even on complete AC
and battery failure. Panel powers up in last armed or
disarmed state before power loss.
• All programmable zones may be selected as one of 10
different types including; delay, auxiliary delay, instant,
interior, interior with home-away, delay with home-away,
and 4 types of 24 hour emergency and supervisory
circuits.
• Keypad programming of up to sixteen security codes.
• Zone bypassing from the keypad.
• Individual zone and system function indicators on keypad.
• A keypad activated utility output function for operating
lights, door openers, cameras or other devices.
Although the PC2550 has many features, it is not difficult to
use. All keypad commands are similar and are assisted by
audible and visual cues.

INSTALLATION
Bench Testing
The PC2550 contains a factory default program. Any
additional programming required can be done through the
keypad. For many applications all that will be required is to
enter the telephone number and alarm codes with keypad
entries that are as straight forward as dialing a telephone
number. If you need help talk to your DSC equipment
distributor.
Connect 1K ohm 1/2 watt end of line resistors from each
zone (Z1 to Z8) input to the closest common “COM”
terminal. Connect an end of line resistor between the “Fire”
input terminal and the “COM” terminal between “Z1” and
“Z2”. Unless all zones are properly terminated with end of
line resistors the “Ready” light will not be on and the panel
will not arm unless the “Ready” light is on.
Connect the four keypad wires to the control panel as
shown in the connection drawing.
To completely test the PC2550 including the communicator
data, it is necessary to connect the panel to a digital
receiver through a telephone line connection or by
connecting the telephone terminals on the PC2550 to a
digital communicator test set such as the DSC DTS-1. The
DSC DTS-1 digital communicator test set is an inexpensive
unit which can simulate the telephone system dial tone and
the receiver hand shake and kiss-off tones as well as
display the data sent out by a digital communicator. Also,
the DTS-1 has a “listen-in” feature which makes it ideal for
monitoring the transmission between communicator and
receiver when the PC2550 is connected to the telephone
line.
If you are using a DTS-1, connect the green and red
telephone clips to the “TIP” and “RING” terminals and
connect the red and black power clips to the “AUX [+]” and
“AUX [-]” terminals on the PC2550. When power is applied
to the panel press the red local-line button on the DTS-1
and observe the display window area. The “local-line”
indicator should be in the local position.
For testing purposes, so that the sound level is not too loud,
connect a small buzzer to the “BELL [+]” and “BELL [-]”
terminals to indicate when the panel is in alarm.
Connect a 16.5 VAC, 40 VA transformer to the “AC”
terminals. Before plugging in the transformer be sure the
circuit board is not resting on anything metallic which may
cause a short.
Note: The PC2550 will not start up if “AC” is off and
the battery is low.
When the transformer is plugged in there should be lights
on the keypad and the buzzer connected to the bell
terminals may go on for a few seconds. The “Armed” light
may be on or off the first time the panel is powered. The
last armed/disarmed condition is stored in the EEPROM
memory so the panel will always power up in the last
armed/disarmed state. If the “Armed” light is on, enter the
default Master Code [1234] to disarm the panel. If the
keypad is not active, check for the presence of AC power
at the “AC” terminals, check the keypad connections and
check the panel fuses.
If all the zones are properly connected with end of line
resistors all of the zone lights will be off. Note that the panel
will arm only if all zones are properly connected with end of
line resistors (including FIRE circuit) so that the “Ready” light
is on. The keypad should beep several times to indicate
acceptance of the master code. Enter the Master Code to
arm or disarm the panel.
Read the “Keypad Commands” section of this manual or the
Instruction Manual and enter commands on the keypad to
become familiar with the different commands.
Turn to the “Programming Guide” in this manual and enter a
sample program into the panel through the keypad to
become familiar with the programming commands.
Mounting Panel
Select a dry location close to an unswitched AC source, a
ground connection and the telephone connection.
Remove printed circuit board, mounting hardware and
keypad from cardboard retainer inside panel. Before
attaching cabinet to wall, press the five white nylon printed
circuit board mounting studs and the ground connection
screw into cabinet from the back.
Pull all cables into cabinet and prepare them for connection
before mounting the circuit board to the back of the cabinet.
Press circuit board down onto mounting studs.
Hook-up Procedure
DO NOT connect transformer or battery until all other wiring
has been connected. See power-up procedure.
Connect a ground cable from the cabinet ground
connection by the shortest and most direct route to a
grounding rod.
Connect zone cables to zone inputs and put end of line
resistors on any unused zones. Connect wires supplying
power for motion detectors to auxiliary supply.
Install keypads and connect wires to keypad terminals on
panel. Connect RJ31-X cord to telephone terminals. Do not
insert plug into RJ31-X jack.
Warning: Do not use this equipment on a telephone
line equipped with “call holding” feature because the
tone generated may interfere with the communicator
operation.
Connect bell or siren to “BELL [+]” and “BELL [-]” terminals.
Observe correct polarity for sirens and polarized bells.
Connect 1K ohm 1/2 watt resistor across terminals to
eliminate trouble condition if bell circuit is not being used.

4
Terminal Connections
“AC” Power Terminals
Use a 16.5 VAC transformer with a minimum 40 VA rating to
supply AC power to the PC2550. The transformer should not
be connected to an outlet that is controlled by a switch. If
AC failure occurs it is displayed as a trouble on the keypad
(see “Keypad Functions [✱][2] Trouble Conditions”). It can
also be transmitted to the monitoring station as a trouble
condition (see “Programming Guide [✱][8]” sections [12]
and [13] for alarm and restore codes and section [20] for
AC transmission delay).
Auxiliary Power Terminals “AUX” and “GND”
The auxiliary power supply can be used to power motion
detectors and other devices requiring 12 VDC. 400 mA 12 VDC
is available from the “AUX” (positive) and “GND” (negative)
terminals when the PC2550 is used with one keypad. For
each additional keypad the auxiliary supply rating must be
reduced by 60 mA. The auxiliary supply is fused with the
keypad supply at 1 amp. Auxiliary fuse failure transmission
can be sent (see [✱][8] sections [12] and [13]).
Switched Auxiliary Power Terminals
“SW AUX” and “GND”
The switched auxiliary supply can be switched off
momentarily from the keypad (see “Keypad Commands
[✱][4]”). The “SW AUX” terminal is positive and the “GND”
terminal negative. The 400 mA auxiliary supply rating must
be reduced by any current taken from the switched auxiliary
supply. The switched supply shares the same fuse as the
auxiliary supply.
Bell/Siren Terminals “BELL [+]” and “BELL [-]”
These terminals are for powering bells or other devices
requiring a steady output voltage on alarm. The bell output
is fused for 5 amps. When connecting sirens (speakers with
siren driver already built-in), be sure to observe the correct
polarity. Connect the positive lead to the “BELL [+]” terminal
and the negative lead to the “BELL [-]” terminal.
If no siren or bell is used, connect a 1000 ohm resistor
between “BELL [+]” to “BELL [-]”. The bell/siren alarm
output is pulsed (1 second on 1 second off) when an alarm
is created by the [F] keypad zone, by the FIRE zone, or
when the Bell Pulse option is enabled in section [18] light 2.
Keypad Terminals “RED”, “BLK”, “YEL” and “GRN”
Connect the four coloured wires from the keypads to these
terminals. When connecting more than one keypad, connect
in parallel across the keypad terminals at the control panel
(i.e. all reds wires together, all blacks together, all yellows
together and all greens together). The keypad red and black
power supply terminals are fused through the auxiliary fuse.
Programmable Output Terminal “PGM OUT”
The operation of the Programmable Output depends upon
which option is selected in the programming table. See the
“Programming Guide” section [30] for a list of options for the
“PGM OUT” output. The “PGM OUT” is a 50 mA maximum
switch to ground. A 100 ohm current limiting resistor is
connected in series. A small relay, a buzzer or other DC
operated device may be connected between the 12 VDC
“AUX” (positive) terminal and the “PGM OUT” (switched
negative) terminal on the main board.
Auxiliary Input Terminal “AUX IN” (also KEY ARMING)
The “AUX IN” input terminal is a normally open 24 hour
zone. It can be programmed from the keypad to be silent or
audible. There is no display on the keypad for the “AUX IN”
input. An alarm on this input is created by applying a
positive voltage or by closing a contact between the “AUX
IN” terminal and the positive auxiliary supply. See
“Programming Guide [✱] [8]” section [11] for programming
the alarm and restoral codes.
The “AUX IN” terminal can also be used as a momentary
key arming/disarming input. See “Programming Guide”
section [30] for a list of options for the “AUX IN” terminal.
”FIRE” Zone Input
The “FIRE” zone is a supervised (normally open alarm
initiating contact) end-of-line resistor circuit designed to
accept “Latching” four-wire smoke detectors.
(See “Fire Circuit Installation Diagram”.)
On alarm, (fire zone shorted) the bell output will pulse the
signal to indicate that the fire zone has been activated.
Alarm memory and transmission by the digital
communicator is delayed 30 seconds. If the alarm is
acknowledged, by pressing the [#] key before the 30
second delay has expired the signals will silence and the
transmission will be aborted. If the alarm is not
acknowledged and the 30 second delay expires, the fire
memory latches and the transmission cannot be aborted.
If after signal silence, the smoke detector is not restored to
normal, the signals will resound after 90 seconds, and 30
seconds after that, the communicator will transmit. If the
signals resound, they may again be silenced, [#] key, and
the communicator will be aborted if silence occurs within the
30 second delay period.
To restore the smoke detector to normal, clear all products
of combustion from the detector and reset the detector by
pressing [✱] and then holding down [4] for 2 or 3 seconds.
This action will remove power from the smoke detector and
if it is clear of smoke, the detector will return to normal. If the
detector is still in alarm, the signals will sound immediately
and the above sequence will repeat.
For an open on the FIRE zone, the keypad sounder will beep
twice every 10 seconds and the “Trouble” light will show on
the keypad. The communicator will transmit the trouble
condition if programmed for trouble transmission. The
audible trouble signal may be silenced by pressing the [#]
key. To determine the nature of the trouble, press [✱][2]
(See the “Trouble Display” section).

5
Zone Input Terminals “Z1” to “Z8”
Zone inputs “Z1” to “Z8” are supervised end of line (E.O.L.)
resistor circuits. Each input must be terminated with a 1K
ohm E.O.L. resistor. An alarm condition will be created if a
normally open contact is used to short across the E.O.L.
resistor. An alarm is also created if normally closed
contacts, wired in series with the E.O.L. resistor, are
opened. See the wiring diagram for normally open and
normally closed contact connection. The type of circuit or
zone definition (delay, instant, 24 hour etc.) is programmed
from the keypad using the [✱][8] Installer’s Programming
commands ("Programming Guide" section [14]).
Telephone Terminals “TIP”, “RNG”, “T-1” and “R-1”
The wires from the RJ31-X telephone jack are connected to
these terminals in the following way.
TIP Green wire Incoming line from
RNG Red wire telephone company
T-1 Brown wire Outgoing line to
R-1 Grey wire house telephone(s)
Note: For proper operation there must be no other
telephone equipment connected between the control
panel and the telephone company's facilities.
Battery Connections
Do not connect the battery or the transformer until the wiring
is complete. Connect the red battery lead to the positive
battery terminal and the black lead to the negative battery
terminal. If the connection is made in the reverse the battery
fuse will fail.
Keypad Installation
Mount the keypads near the exit-entry doors. The
PC2550RK keypad has a red, a black, a green and a yellow
wire on the back. Connect these four wires to the four
keypad terminals on the control panel using four conductor
(quad) telephone wire. Up to three keypads may be
connected to one PC2550. Connect all green wires from the
keypads to the “GRN”terminal on the panel. Connect all
yellow wires from the keypads to the “YEL”terminal on the
panel. Connect all red wires from the keypads to the “RED”
terminal. Connect all black wires from the keypads to the
“BLK”terminal.
Power-up Procedure
If the keypads are located a distance from the panel, install
an extra keypad temporarily at the panel during power up
testing. An extra keypad with a short length of cable and
alligator clips attached is helpful for testing and
programming PC2550 systems.
Connect the transformer, wait approx. 5 seconds.
Enter a few keypad commands and open a zone to be sure
that the panel and keypad are responding to signals. If the
keypad does not respond and there are no indicators on,
check for AC voltage at the “AC”terminals. If there is 16
VAC present, check that the keypad wiring is correct and
check the keypad/auxiliary supply fuse. If the keypad/
auxiliary supply fuse is blown check for a short between the
keypad red and black wires before replacing the fuse.
If the keypad is responding normally, connect the battery.
The red battery lead attaches to the positive battery post
and the black battery lead attaches to the negative battery
post.
Note: The PC2550 will not start up if “AC” is off and
the battery is low.
Testing The System
See Installer’s test - [✱] [6] [Master Code] [0] (page 9), or
do the following. Contact the monitoring station to request a
transmission test. Plug the telephone cord into the RJ31-X
jack. If a DTS-1 is being used to monitor communicator
transmissions, connect as described in “Bench Testing”
section and place the DTS-1 in the line mode by pressing
the red “LINE/LOCAL”button. Arm the panel, wait for the
exit delay to expire and trip a detector on an instant circuit.

GUIDELINES FOR SMOKE
DETECTOR LOCATION
Experience has shown that all hostile fires in family living
units generate smoke to a greater or lesser extent.
Experiments using typical fires in family living units indicate
that detectable quantities of smoke precede detectable
levels of heat in most cases. For these reasons, smoke
detectors should be installed outside of each sleeping area
and on each additional story of the family unit.
The following information is for general guidance only and it
is recommended that the smoke detector manufacturer's
literature be used for detailed installation instructions.
It is recommended that additional smoke detectors beyond
those required be installed for increased protection. The
added areas include: basement, bedrooms, dining rooms,
furnace room, utility room and hallways not protected by the
required detectors.
FIG. 1: A smoke detector should be located between
the sleeping area and the rest of the family unit.
FIG. 2: In the family living units with more than one
sleeping area, a smoke detector should be located to
protect each sleeping area.
FIG. 3: A smoke detector should be located on each
story of the living unit.
FIG. 4: Smoke Detector mounting - “Dead” Air Space.
The smoke from a fire generally rises to the ceiling,
spreads out across the ceiling surface and begins to
bank down from the ceiling. The corner where the
ceiling and wall meet is an air space into which the
smoke may have difficulty penetrating. In most fires,
this “dead” air space measures about 4 in. (0.1m) along
the ceiling from the corner and about 4 in. (0.1m) down
the wall as shown in Figure 4. Detectors should not be
placed in the dead air space.

KEYPAD FUNCTIONS
Introduction
The PC2550RK remote keypad provides complete
information and control of the PC2550 control panel. The
panel can be fully programmed from the keypad. The 8
zone lights and the fire alarm light provide alarm and status
indication for the alarm circuits. The 6 function lights guide
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 resting in the arm-disarm mode. In
this condition the zone lights are indicating the opening and
closing of zones. The “Ready”light 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.
Master Code
A default Master Security Code “1234”is programmed into
the PC2550 at the factory. The Master Security Code is used
for arming and disarming the control panel, for
programming up to fifteen additional security codes using
the [✱][5] command and for entering other user functions
using the [✱][6] command. The Master Code can be
reprogrammed if the installer leaves section [16] light 2 off.
Because the PC2550 uses EEPROM memory the codes and
other data are retained even after complete AC and battery
failure.
2nd Master Code
A second master security code “xxxx”can be programmed
into the PC2550. This code can be changed by the installer
only, and is useful where there are multiple panels in a
complex. The 2nd Master Code can be used as a “Master
Key”. The default 2nd Master Code is blank.
Installer’s Programming Code
A default Installer’s Programming Code “2550”is
programmed into the PC2550. This code is used with the
[✱][8] command by the installer to gain access to the
system in order to enter panel or communicator program
information. The Installer’s Programming Code may be
changed by the installer.
Arming
Check to see if the “Trouble”or “Bypass”light is on before
arming the PC2550. Close all protected doors and windows
and stop movement in areas covered by motion detectors.
Check to see that the “Ready”light is on (all zones are
closed). The system cannot be armed unless the “Ready”
light is on. Enter a [4 Digit Security Code]. As each digit is
entered the keypad buzzer will beep. If the security code
was entered incorrectly, the sounder will beep steadily for 2
seconds. If the code was entered correctly but the “Ready”
light was not on, the keypad will beep quickly followed by a
steady tone. When the correct code is entered, the “Armed”
light will come on and the keypad buzzer will beep quickly.
Exit the premises through the designated exit-entry door. At
the end of the allowed exit time all lights on the keypad will
go out except the “Armed”light. See the “Installer’s
Programming [✱][8] Command”section for instructions on
how to change the exit time. Also see, “Quick Arm”and “At
Home Arming”.
Disarming
Enter the premises through the designated exit-entry door.
The keypad buzzer will be on. Go to the keypad and enter
the [4 digit security code]. If an error is made in entering the
code, press the [#] key and enter the code again. The
“Armed”light will go out and the keypad sounder will stop.
The correct security code must be entered before the
allowed entry time expires. To change the entry time see
“Installer’s Programming Command”, [✱][8]. If an alarm
occurred while the panel was armed, the “Memory”light and
the “Zone”light which caused the alarm will start to flash
and stay flashing for 2 minutes when the panel is disarmed.
Pressing the [#] key returns the panel to the normal arm-
disarm mode.
Auto-bypass/Home-Away Arming
If a correct security code is entered, and you do not exit the
premises, 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. The “Bypass”light will come on immediately following
the arming code being entered until a delay zone is tripped
or [✱] [1] is entered to reactivate bypassed home-away
zones. (See programming section [14], zone definitions for
programming zones as “Home-Away”.)
This is a convenience feature for the user who wishes to
remain at home with the system armed. The user does not
have to manually bypass the home-away zones.
To reactivate the home-away zones that have been
automatically bypassed, press [✱] [1]. The “Bypass”light
will go out. This command is a quick method of fully arming
the system before going to bed.
Zone Bypassing
[✱]+[1] or [✱]+[1]+[Access Code]
A bypassed zone will not cause an alarm. If a zone is
bypassed the panel may be armed (“Ready”light will be on)
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.
If section [18] light 3 is on, all bypassed zones will be shown
when armed. Home-Away zones that are automatically
bypassed will show as well. This feature cannot be used with
a split armed system. If section [17] light 8 is on then the
bypass status will always be shown.
To bypass zones, enter [✱] [1] and the zone number(s) to
be bypassed. Press [#] to return to “Ready”(arm-disarm
mode). To remove all bypasses, enter [✱] [1] [0] [#]. The
“Zone”lights which are on, while the “Bypass”light is
flashing, indicate the bypassed zones. Remember that if no
keypad entry is made for more than 2 minutes the keypad
will return to the arm-disarm mode. Then, in order to bypass
a zone the complete command must be re-entered. Once

3 Day Zone Trouble...
This trouble applies only to zones
which have been programmed as day zones.
(“Programming Guide” section [14]). A day zone creates a
trouble signal when the panel is disarmed and an alarm
signal when the panel is armed.
4 Telephone Line Trouble... A telephone line trouble is
generated when the line voltage drops below 3 volts for
more than 30 seconds. It generates a keypad trouble when
the system is disarmed and rings a local alarm when the
panel is armed. See section [16] for options.
5 Fail to Communicate... If the digital communicator is
unsuccessful communicating with the monitoring station
after eight attempts to each phone number that is to be
tried, a trouble is generated. If a later attempt to
communicate is successful the trouble is cleared. Also the
trouble will be cleared when the trouble display is viewed
and exited.
6 Bell Circuit Failure... If the bell fuse fails or the bell circuit
is open, a keypad trouble and a trouble transmission are
generated.
7 Fire Alarm Circuit Trouble... If a FIRE zone is open
circuit, a keypad trouble and a trouble transmission are
generated. A trouble on the FIRE zone will unconditionally
initiate an audible indication on the keypad. This means that
even if any other previous trouble has been silenced, a FIRE
zone trouble will restart the keypad buzzer.
8 Loss of Internal Time... When the PC2550 is powered up
or reset, the internal time of day clock needs to be set to the
correct time. This trouble is cleared when the trouble display
is viewed and exited or when an attempt is made to reset
the internal time of day clock. See “[✱][6] User’s Function
Command” for resetting time of day clock.
If the [9] is pressed while in the trouble display mode the
most recent trouble will be displayed on the zone LEDs. This
trouble memory feature is useful as a diagnostic aid when
installing and servicing the PC2550.
Alarm Memory Display
[✱]+[3]
Press [✱] then [3] to enter the alarm memory mode. The
“Memory” light will flash and any alarm caused during the
last armed period will be displayed on the zone lights. In
addition to the last alarm memory there are 2 history levels.
After entering the memory mode (pressing [✱] then [3]),
pressing [9] will cause the keypad to display the two other
levels of alarm history. Each time [9] is pressed the keypad
will beep 1, 2 or 3 times to indicate which level of history is
being viewed. When the panel is armed, the last alarm
memory is cleared and the contents moves to the 1st history
level. The “Memory” light will only be on when there was an
alarm during the last armed period.
Press [#] to return to “Ready”.
the bypass command is entered, pressing [9] recalls the
last zone or group of zones which was bypassed. If the
same group of zones is bypassed each time, this bypass
recall feature can be used instead of having to bypass
zones individually.
When the PC2550 is programmed, the ability to bypass
certain zones may be eliminated. In this case, the “Zone”
lights for those zones will not come on in response to the
bypass command. See the “Zone Bypass Mask” instruction
in the [✱][8] Installer’s programming section. If the “Bypass”
light is on when arming the panel, the [✱][1] command
should be used to see which zones are bypassed so that
zones are not unintentionally bypassed. Zone bypasses are
automatically cancelled when the panel is disarmed.
If light 8 in section [16] is on then a code must be entered
with [✱]+[1] to bypass zones. Only the zones assigned to
the same side of the system as the user code can be
bypassed. The ability to bypass using certain access codes
can be eliminated. See the “Access Bypass Mask”
instruction in the [✱] [8] Installer’s Programming section.
Note: At no time can any armed zone be bypassed.
Trouble Display
[✱]+[2]
The PC2550 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
but the “Trouble” indicator light will remain on until the
trouble is cleared. Trouble conditions can also be
transmitted to the monitoring station (see “Programming
Guide” sections [12] and [13] for alarm and restoral trouble
codes). Press the [✱] then [2] keys to display the type of
trouble. The “Zone” lights indicate the type of trouble
condition.
1 Low stand-by battery
2 AC power failure
3 Day zone trouble
4 Telephone line trouble
5 Fail to communicate
6 Bell circuit failure
7 Fire alarm circuit trouble
8 Loss of time on internal clock
Press [#] to return to “Ready”.
1 Low Battery... A battery trouble will be displayed and can
be reported if the battery is weak, disconnected or the
battery fuse is blown. Only one low battery alarm or restoral
transmission takes place per arming period. Low battery
trouble display is latching and can only be cleared by
battery restoration, and arming and disarming the panel.
2 AC Power Failure... 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 1 to 99 minutes. See “Programming Guide” section [20].

Switched Auxiliary Supply Control
[✱]+[Hold Down 4]
To interrupt the switched auxiliary power supply press [✱]
then hold down [4] for the desired interrupt time. When the
[4] is released the system returns to the ready mode and
the switched auxiliary supply is restored.
User’s Programming Commands
[✱]+[5]+[MASTER CODE]
The [✱][5] user’s programming commands are used to
program additional access codes. Up to 16 user arm-disarm
codes may be programmed. The 1st code is the Master
Code (factory default [1234]). The 16th code is optionally a
“One Time Use”or maid code. The 16th code may be
changed from a “One Time Use”code to a regular code
using an installer’s programming command (section
[15]...light 8). Remember if no keypad entry is made for
more than 2 minutes the keypad will return to the normal
arm-disarm display and the complete command will have to
be re-entered to program a new access code.
Programming Additional Access Codes
11
11
1 Press the [✱] and [5] keys then enter the Master Security
Code (default [1234]) to enter the additional code
programming mode. The “Program”light and “Zone 1”light
will be on to show that the first code (the Master Code) is
already programmed with the factory default code [1234].
The Master Code may be changed but do not try to erase
the Master Code. The installer can disable user changing of
the Master Code by turning on light 2 in section [16].
22

Master Code may be changed but it must not be removed.
When changing the Master Code be sure to enter a valid 4
digit number (use only number keys 0 to 9). Do not enter [#]
or [✱] as one of the digits. If the Master Code is forgotten
and the panel is left disarmed, program a new Master Code
using the [✱][8][Installer’s Code][25] command. If the
Master Code is forgotten and the panel is left armed, use
the 2nd Master Code to disarm the system. If the 2nd
Master Code is not programmed then the entire
programming can be reset to factory default by using the
“Hardware Reset”method described on page 24.

Installer’s Test
[✱✱
✱✱
✱]+[6]+[MASTER CODE]+[0]
This feature is designed to assist the installer in testing the
system. In this mode, the bell or siren will operate for 2
seconds each time a device is tripped and the first level of
memory will be affected. The feature is automatically
disabled when the panel is armed and disarmed. Each time
a zone is tripped or restored in this mode, a signal, if
programmed, will be transmitted to the monitoring station. If
this is not desired, it is possible to disable the communicator
during the test (see section [15] “1st System Option Code”).
Notes: Do not use the PC16OUT module during the
installer’s test.
Do not use the installer’s test when the panel is
partially armed.
Setting the Clock
[✱]+[6]+[MASTER CODE]+[1]
Setting the “System 24 Hour Clock”(item [1]) tells the
system the correct time of day. If the system is without
battery and AC power it cannot continue to keep time.
Therefore when the panel is first powered up or when it has
been without AC power long enough to completely
discharge the stand-by battery, the “System 24 Hour Clock”
must be reset. If the time needs to be reset a “Trouble #8”
will be indicated on the keypad (see [✱][2] “System Trouble
Command”).
Auto-arm Time of Day
[✱]+[6]+[MASTER CODE]+[2]
The PC2550 can be programmed to arm at the same time
each day. Programming item [2] sets this time and the
feature must be enabled as shown in item [5] (see “Auto-
arm Enable”on this page).
At the selected auto-arm time the keypad beeper begins to
sound and the Bell/Siren will pulse once every 10 seconds to
alert anyone on the premises that the system is about to
arm. The Bell/Siren pulse can be silenced in section [17] by
turning light 1 on.
The keypad beeper will sound for one minute before auto-
arming unless one of the following two methods is used to
abort the auto-arm.
•Auto-arm cancel: Any key can be pressed to cancel the
auto-arm sequence and silence the keypad during the
one minute pre-alert (this is the default condition).
•Auto-arm cancel with code: If section [17] light 4 is on,
then a valid 4 digit access code is required to cancel the
auto-arm sequence.
The auto-arm will be attempted at the same time the
following day. Any time an auto-arm is cancelled using one
of the above methods, the reporting code programmed in
section [08] will be transmitted to the central station.
When the panel does arm by auto-arming, any open zones
will be “Force-armed”. If light 5 in section [18] is on, the
panel will send a partial closing code to let the central
station know zones were bypassed. If section [16] light 1 is
on, the zones that were force-armed will be identified by
transmitting their alarm code along with the partial closing
code.
Quick Arm
[✱]+[6]+[MASTER CODE]+[4]
The “Quick Arm”feature is enabled by pressing the [4] key
while in the “User Functions Command”section. When
enabled (enabled 3 beeps....disabled one long beep) the
panel can be armed by entering [✱][0]. The closing code
transmitted for “Quick Arm”is the same as the code which
is programmed for the Master Code.
Auto-arm Enable
[✱]+[6]+[MASTER CODE]+[5]
Entering [✱] [6] [Master Code] [5] will enable/disable the
Auto-arming feature. When the feature is being Enabled, the
keypad buzzer will sound 3 beeps and when being Disabled
the buzzer will sound one long beep.
Door Chime
[✱]+[6]+[MASTER CODE]+[6]
The “Door Chime”feature is enabled by pressing the [6] key
while in the “User’s Functions Command”section. When
enabled the keypad buzzer will beep quickly 5 times each
time any zone defined as a delay or instant circuit opens or
closes. The “Door Chime”feature does not operate on other
zone definitions. Zone bypass may be used to eliminate
“beeping”on doors where it is not wanted. This feature
operates only while the panel is disarmed.
System Test
[✱]+[6]+[MASTER CODE]+[8]
The system test feature sounds the bell or siren, lights the
keypad indicators and beeps the keypad buzzer for 2
seconds. If a code is programmed in section [50] it will be
transmitted at the same time.
User Callup
[✱]+[6]+[MASTER CODE]+[9]
This function is enabled in section [47]. When activated,
the panel will call the downloading computer. The
downloading computer must be waiting for the panel to
call before downloading can be performed.

11
Utility Output Command
[✱]+[7] OR [✱]+[7]+[ACCESS CODE]
The programmable output (PGM terminal) on the PC2550
can be made to activate by a command from the keypad.
This output can be used for operating other devices such as
garage door opener, special lighting or door strikes.
The programmable output must be selected for keypad
utility using the [✱][8][Installer’s Code][30] command and
programming a [2], [3], [4] or [5].
Depending on the option chosen in the programming
section, the programmable output is activated by pressing
the [✱] then [7] keys followed by a Group A access code,
Group B access code, any access code, or no code at all.
When the proper keys are pressed the keypad sounder and
the programmable output are activated for 5 seconds.
Installer’s Programming Commands
[✱]+[8]+[INSTALLER’S CODE]
The PC2550 is completely programmed from the keypad by
using commands in the [✱] [8] section. The commands are
described in detail in the programming section of this
manual.
“At Home” Arming
[✱]+[9]+[ACCESS CODE]
Entering [✱], [9] before the arming code, arms the panel
without any entry delay on the delay zones and bypasses
zones that are defined as “Home-Away”. This command is
used for arming the system while at home. When the panel
is armed using [✱], [9], the “Armed”light will be on flashing
and the bypass light will be on to indicate that the “Home-
Away”zones are bypassed. Once the panel is Armed in this
mode, using [✱], [1] will remove the bypass from those
zones defined as “Home-Away”if they have
NOT been
manually bypassed. The [✱], [1] command used here, only
removes the bypass from zones that have been
Automatically bypassed with the [✱], [9] command.”
“Quick Arm” Command
[✱]+[0]
Entering [✱][0] is accepted as a valid arming code when the
“Quick Arm”feature is activated. Quick Arm may be used
as a convenience for regular users or when the system is to
be armed by individuals who are not authorized to disarm
the system. See instructions in the “[✱][6] User’s Functions
Command”section for activating the “Quick Arm”feature.
This feature should not be enabled if the One Time Use
Code is enabled. The One Time Use Code must be used for
arming before it is erased.
Quick Exit
[✱]+[0] When Armed
Entering [✱] [0] when the system is fully armed will allow the
user 2 minutes to exit the premises through any delay zone
without altering the status of the system if the Quick Exit
feature is enabled. The Quick Exit feature can be enabled
by turning on light 1 in section [18]. After [✱] [0] is entered
into an armed system, one and only one delay zone may be
tripped. Any additional activity on any other active zone will
cause that zone to begin its alarm sequence.
[✱] [0] for Quick Exit on a partially armed system is not
supported.
Quick Exit is not designed to extend the standard Exit Delay.
It must not be used when auxiliary delay zones are force
armed. Turn light 6 in section [17] off to ensure proper
operation.
Keypad Zones
There are three zones which can be activated from the
keypad. The alarm and restoral codes for keypad zones are
programmed using the [✱][8] command.
Pressing the [F] key or the [1] and [3] keys for 2 seconds
activates a Fire alarm. The fire alarm sounds the siren/bell in
a pulsed mode and is annunciated as a memory condition.
The Fire key can be turned off in section [18].
Pressing the [A] key or the [4] and [6] keys for 2 seconds
activates an Auxiliary keypad zone. If a reporting attempt is
made to an alarm receiver and it is successful the PC2550
will acknowledge the transmission with a short series of
beeps from the keypad.
Pressing the [P] key or the [✱] and [#] keys for 2 seconds
activates the Police (or Panic) alarm. The panic alarm can
be programmed for audible or silent operation (see sections
[15] and [18] in “Programming Guide”).
There is no light annunciation from the keypad for the last
two keypad zones, however, the keypad buzzer beeps 3
times to confirm activation on any of the keypad zones.
See section [11] for alarm and restoral codes for all three
keypad zones.

Section [47] - Modem Configuration
Zone lights [1] to [4] are programmed to set the number of
rings the panel will look for before it answers a call from the
downloading computer.
Zone light [5] is programmed to enable or disable the
control panel for downloading. If downloading is disabled, all
other programming sections relating to downloading need
not be programmed.
Zone light [6] enables or disables user initiated callup to the
downloading computer.
Zone light [7] enables or disables the answering machine
defeat option (Answering Machine Over-ride).
Downloading and Answering Machine
The PC2550 software provides a means to handle
downloading when an answering machine is also connected
to the telephone line. In section [47], if zone light 7 is off, it is
assumed that there is no answering machine connected to
the telephone line and the panel will capture the line after
the set number of rings.
If zone light 7 is off and an answering machine is connected
and it is set to answer before the panel, the panel will be
unable to receive a call from a downloading computer. If the
panel is set to answer before the answering machine, the
answering machine will be unable to receive incoming
messages.
If zone light 7 is on and the panel is called for 1 or 2 rings
only and then called again within a set time of 1 to 249
seconds (set in section [49]), the panel will then answer the
second call on the first ring (Answering Machine Over-ride
Timer).
Once the panel is connected to a downloading computer,
no [✱] functions can be performed. If the [✱] key is pressed
while the panel is connected to a downloading computer,
the keypad buzzer will sound one long tone to indicate an
error.

Zone light [8] is programmed to enable or disable
callback. If callback is disabled, the downloading
computer will have immediate access to the control panel.
The disabled mode is useful if there are multiple
downloading computers (at different telephone numbers).
If callback is enabled the downloading computer will call,
request access then hang up and wait for the control
panel to call. After the control panel has called back and
the downloading computer and the control panel accept
each other as valid, downloading operations are enabled.

PROGRAMMING GUIDE
13
Introduction
The PC2550 is programmed by entering instructions from
the panel keypad. The PC2550 memory is EEPROM and
can be reprogrammed thousands of times. The EEPROM
will not lose memory even on total AC and battery failure. All
essential program information required to define the
operation of the control panel and the communicator is
stored in a section of the EEPROM which can only be
accessed using the Installer’s Programming Code. If the
code is forgotten, the default program code can be re-
inserted by using the “Hardware Reset”described on page
23, unless Installer’s Lockout is enabled. See sections [90]
and [91].
To begin programming the PC2550, enter [✱] [8] [2550]
while the panel is disarmed. Installer’s Programming can only
be done while the panel is disarmed and not in alarm. The
factory default Installer’s Programming Code is [2550]. This
default code can be changed using the Section [24] command
listed below (new Installer’s Code). Once the basic Installer’s
command is entered ([✱] [8] [2550]) the “Program”light will
start to flash. The “Program”light will continue to flash while
programming. Note that while programming, if no key entry is
made for more than 2 minutes, the keypad will return to the
arm-disarm mode and the complete installer’s command ([✱]
[8] [2550]) must be entered before programming can resume.
The next step is to enter a 2 digit section entry for any of the
commands described in the following pages. Note that while
the keypad is waiting for the section entry the “Armed”light is
on steady. As soon as the 2 digits are entered for the section
the keypad will beep 3 times, the “Armed”light will go out and
the “Ready”light will go on. The keypad is then ready to accept
data entry for the selected section.
A complete description of each programming section will be
given in the remaining pages of this section. A programming
work sheet summarizing all programming commands is
provided in the next section of the manual. Fill out the work
sheet and use it as a guide when programming.
As the required data for a programming section is entered, the
hexadecimal value of the information in that location is displayed
on zone lights 1-4. Most sections contain several groups of two
digit entries. The keypad beeps twice and the “Armed”light
flashes after each group of two digits is entered. When the
required data is completely entered for the section being
programmed, the keypad will beep 5 times and the “Armed”
light will come back on to indicate that the expected data has
been entered and another section can be selected for
programming. After completing one section, it is not necessary
to re-enter the [✱] [8] [Installers’code] portion of the command.
Just enter the number of another programming section. When
programming a section, it is possible to exit by pressing [#].
Only the data entered before pressing [#] will be changed in the
EEPROM. Practice entering data in several sections until you
become familiar with the programming commands.
Certain programming entries may require “HEX”data. That is
the numbers 0 through 9 and the letters A through F (in “HEX”
numbering the letters A...F represent the numbers 10...15).
Where commands require “HEX”data A-F, first press [✱]. The
keys 1-6 now assume the hex values A-F and the “Ready”light
begins to flash. Key 1=A, Key 2=B, Key 3=C, Key 4=D, Key
5=E and Key 6=F. Pressing the [✱] again stops the “Ready”
light from flashing and the keys assume the normal values
for the numbers from 1 to 9. The most common mistake in
entering “HEX”data is forgetting to press [✱] again after
entering the “HEX”digit to return to normal number entry.
The data for sections 15, 16, 17, 18, 19, 31, 32, 33, 34, 47,
48, 52 and 53 is entered using the keypad zone lights to
indicate which functions are active and the number keys to
turn functions on and off. When the section number is
entered, the zone lights 1...8 will display which functions are
currently on. Pressing the number key corresponding to the
zone light alternately turns the function on and off. All
functions can be turned off by entering [0]. When the
correct selections have been made press [#] to record them
in memory and to go on to program the next section.
Binary Data Display
Zone lights 1 through 4 are used to display the binary
value of the data as shown in the table below.
Reviewing Programmed Data
Enter the section you wish to review by entering the 2 digit
section number. The zone LEDs will represent the value
(hexadecimal format) of the first digit in that section. Each
press of the ‘F’key will advance the display to the next digit.
At the end of the section, the keypad buzzer will beep
several times and return you to the program mode where
another section can be selected for review or programming.
Note: Only sections [01] through [14], [20] through
[30], [35], [46], [49], [50], [54] and [55] can be reviewed
using the above method.
[00] Binary Programming
This section is normally used upon instruction from factory
technical personnel for specialized programming not
covered by the standard programming instructions.
[01] 1st Phone Number
This is the 1st telephone to which the communicator will dial.
See section [35] “Transmission to 1st or 2nd Telephone
Number Options”. After entering the section number [01],
enter the communicator telephone number the way you
would dial it on a telephone. Press [#] after the last digit to
complete the telephone number programming.
Enter [ ✱2 ✱] to dial a ‘✱’(Hex B)
Enter [ ✱3 ✱] for a 4 second pause (Hex C)
Enter [ ✱4 ✱] for additional dial tone search (Hex D)
Enter [ ✱5 ✱] to dial a ‘#’(Hex E)
The total number of digits including dial tone searches and
pauses must not exceed 17. Remember to press [#] after
entering the last digit of the phone number. Press [02] to
program the next section, enter another section number or
press [#] a second time to return to the arm/disarm mode.

[02] 1st Account Code
The 1st account code is always transmitted to the 1st phone
number to identify the alarm customer. After entering the
Section number [02], enter a 4 digit number. If “HEX”digits
A to F are required; enter [✱], [1]...[6] and [✱] again to
return keys to normal decimal entry. Where a zero digit in
the account code is required use “HEX A”([✱][1][✱] to
transmit 10 pulses. The receiver at the monitoring station
interprets 10 pulses for a digit as a zero. If a three digit code
is required as in 3/1 formats, enter [0] as the last digit. [0]
represents a null digit....no pulses transmitted.
[03] 2nd Phone Number
This is the second telephone number to which the
communicator will dial. See section [01] “1st Phone
Number”for programming instructions.
[04] 2nd Account Code
The 2nd account code is always transmitted to the 2nd
phone number. See section [02] “1st Account code”for
programming instructions.
Reporting Codes Explanation
Sections [05] to [13] are used to program the communicator
reporting codes. A reporting code is transmitted along with
the account code with each transmission. If the reporting
codes are not programmed in these sections no
transmission will be sent when an event (i.e. alarm, restoral,
opening/closing, trouble etc.) takes place. To prevent a
transmission from being sent for any event in the following
sections leave it unprogrammed or enter [00] as the
reporting code.
Between 6 to 10 reporting codes are programmed in each
section. Once the section number is entered, the keypad
expects 6 to 10 two digit numbers to be entered for the
number of reporting codes in that section. The keypad
beeps twice and the “Armed”light flashes after each 2 digit
number is entered. After the last code is entered,
programming of the current section is complete. The
keypad will beep 5 times, the “Ready”light will go off and
the “Armed”light will go on. The keypad is then ready to
accept the next section number for programming.
When changing the reporting codes in a section, only code
entries up to the one which is being changed need to be
entered. Press [#] to exit from the programming sequence.
Only codes up to the last one entered will be changed.
[05] Alarm Reporting Codes Zones 1 to
8
Once the Section code [05] is entered, the keypad expects
8 two digit numbers to be entered as the reporting codes for
zones 1 to 8 alarms (restorals in section [06]). These codes
are used by the communicator when there has been an
alarm on zones 1 to 8. Listed below are several
programming examples and the resulting transmission using
different formats for the reporting codes. Obtaining different
formats requires entering data correctly in the account code
section ([02] or [04]) reporting codes sections ([05] to [13],
[50], [54] and [55]) and communication format options,
section ([29]).
3/1 Format....Single Line or Non-extended Reporting
Required:
•3 digit account code in sections [02] or [04]
i.e. enter [1230] for account code 123
•Format code [0], [1], [2], [3], [4] depending on receiver
type selected in section [29]
•Single digit alarm reporting code in section [05]
i.e. enter [30] for single digit code 3 (0 is null digit i.e. no
pulses transmitted)
Transmission sent:
•123 3
4/2 Format....Single Line Reporting
Required:
•4 digit account code in Sections [02] or [04]
i.e. enter [1234] for account code 1234
•Format code [0], [1], [2], [3], [4] depending on receiver
type selected in section [29]
•Two digit alarm reporting code in section [05]
i.e. enter [31] for two digit code 31
Transmission sent:
•1234 31
3/1 Format....Extended Reporting
Required:
•3 digit account code in Sections [02] or [04]
i.e. enter [1230] for account code 123
•Format code [8], [9], [A], [B], [C] depending on receiver
type selected in section [29]
•Two digit alarm reporting code in section [05]
i.e. enter [31]
Transmission sent:
•1st round 123 3
•2nd round 333 1
If a transmission is not wanted for a particular reporting
code, then enter 00 to disable that reporting code.
[06] Restoral Reporting Codes
Zones 1 to 8
These reporting codes are used by the communicator to
transmit a zone alarm for zones 1 to 8. Use instructions in
section [05] as a guide for programming.

15
[07] Reporting Codes for Closing
(Arming) with Access Codes 1 to 8
The reporting codes in sections [07] to [10] are used to
identify “Openings and Closings”(disarming and arming of
the system) by user access code.
After entering the section code [07], enter 9 two digit
reporting codes. The 9 reporting codes correspond to the
first 8 access codes which are programmed using the [✱][5]
command and then the partial closing code in last. When
the system is armed using one of the access codes, the
corresponding reporting code is transmitted.
When transmitting in any of the extended formats, (see
examples in section [05]), closing codes would be
programmed as follows. [C1], [C2], [C3], [C4], [C5], [C6],
[C7], [C8]........Where the first digit “HEX C”is one which is
used to represent a closing signal (this could be another
number depending on what is used at the monitoring
station) the 2nd digit represents the access code which was
used to arm the system.
The closing code transmission takes place after the exit
delay time. Therefore if the system is armed and
disarmed before the expiry of the exit time, no
transmission will take place.
Remember that the 1st access code is the Master Code and
that the 16th code may be the temporary or maid’s code.
The 16th access code can be converted to a normal code
by turning light 8 off in section [15].
When the system has been armed using “Quick Arm”[✱][0]
or “Auto-arm”(see [✱][6] “Keypad Commands”), the 1st
reporting code (reporting code for Master Code) will be
transmitted. The Master Code is required to enable or
disable these functions.
When the system is armed with one or more zones
bypassed (see [✱][1] command for zone bypassing), the
monitoring station can be notified by programming the
Partial Arm reporting in section [16]. Note that the partial
closing code is sent in tandem with the regular closing code
to identify it as a partial closing condition. If section [16] light
1 is on then the bypassed zones will be identified between
the partial closing and the closing code by sending their
alarm code transmissions.
[08] Reporting Codes for Closing
(Arming) with Access Codes 9 to 16
The Auto-arm Cancel code is described on page 10 under Auto-
arm Time of Day. See section [07] for programming information.
[09] Reporting Codes for Opening
(Disarming) with Access Codes 1 to 8
The 8 reporting codes correspond to the first 8 access
codes which are programmed using the [✱][5] command.
When the system is disarmed using one of the access
codes, the corresponding reporting code in this section is
transmitted.
See section [07] for an example of “Opening and Closing”
reporting code programming.
[10] Reporting Codes for Opening
(Disarming) with Access Codes 9 to 16
See section [09] for further information.
If the opening after alarm code is programmed, that code
will be transmitted to the monitoring station on opening if an
alarm occurred during the previous armed period. This
feature is useful for installations where openings and
closings are not reported normally but it is desired to have a
report to the monitoring station on opening if an alarm did
occur during the previous armed period. This feature allows
the monitoring station to know when the user is on the
premises and available to receive a report about alarms that
occurred while the system was closed.
[11] Reporting Codes for Priority
Alarms and Restorals
These reporting codes are used by the communicator to
transmit the following list of alarm and restoral conditions.
Use instructions in section [05] as a guide for programming.
See “Terminal Connections”section of manual for a
description of the operation of the Fire Zone and the
Auxiliary Input Zone. Section [30] contains options for
Auxiliary Input Zone.
•Fire Zone
•Auxiliary Input Zone
•Keypad Panic Alarm [P]
•Keypad Fire Alarm [F]
•Keypad Auxiliary Alarm [A]
•Fire Zone Restoral
•Auxiliary Input Zone Restoral

•Keypad Fire Restoral [F]
•Keypad Auxiliary Restoral [A]
12] Reporting Codes for Maintenance
Alarms
The reporting codes programmed in this section include the
periodic test reporting code (every 1 to 99 days) and trouble
conditions. The battery trouble reporting code will be sent
when the battery voltage drops below 11.3 volts. This
reporting code will also be sent because of a battery fuse
failure. The battery is tested under load every 4 minutes. The
AC failure trouble reporting code will be sent after the delay
time programmed in section [20]. This prevents
transmissions during temporary power failures. Auxiliary
power supply trouble reporting code is sent when the
auxiliary power supply fuse is blown. The bell circuit trouble
reporting code is sent when the bell circuit is open or the
fuse is blown. The fire zone trouble code is sent when the
fire zone becomes open circuit (E.O.L. resistor is
disconnected). The day zone trouble code is sent when any
zone defined as a day zone (see section [14]) goes open
when the system is disarmed. See [✱][2] Trouble Command
for additional description of trouble codes and
transmissions. The periodic test cycle time is set in section
[20] and reporting time of day is set in section [23].

[14] Zone Definitions for Zones 1 to 8
As in section [5], once this section number is entered, 8 two
digit numbers are required. Each 2 digit number entered
describes how a zone will operate. The 8 two digit numbers
entered correspond to zone definitions for zones 1 to 8.
1st Digit 2nd Digit
0 = Slow, audible 0 =Standard delay
1 = Slow, silent 1 =Instant
2 = Fast, audible 2 =Interior
3 = Fast, silent 3 =Home-Away
4 =24 Hour..bell
5 =24 Hour..bell/buzzer
6 =24 Hour buzzer
7 =Auxiliary delay
8 =Day
The 1st Digit determines whether the zone will cause a
silent alarm or an audible alarm and whether the zone
response will be fast or slow. Slow zone response time can
be programmed in section [20] and can be set from 10 to
990 ms. The factory default zone response time is 500 ms. If
set at fast, the zone response time is 20 ms and, if set at
slow, the zone response time is 500 ms or whatever time is
set in section [20].
The 2nd Digit determines the zone type, [0] through [8] as
described below.
[0] = Standard Delay Zone has an entry and exit delay and
is normally used for entry/exit doors. The exit delay starts as
soon as the panel is armed. The zone may be opened and
closed during the delay time without causing an alarm. After
the exit delay time has expired, opening the zone will start
the entry delay timer. During the entry delay time, the
keypad buzzer will sound steadily to advise the user that the
system should be disarmed. If the panel is disarmed before
the entry time expires, no alarm will be generated.
The default times for this type of zone are a 30 second entry
delay and a 120 second exit delay. The entry and exit
delays may be independently programmed in section [20]
for periods from 1 to 255 seconds. All zones programmed
as type [0] will have the entry and exit delays as
programmed in section [20] or the default times if section
[20] is not programmed.
[1] = Instant Zone is normally used for door and window
contacts and has the standard exit delay but is instant when
opened after the exit delay expires. The exit delay will be the
default time of 120 seconds or the time as established in
programming section [20].
[2] = Interior Zone is normally used with interior motion
detectors and has the standard exit delay time. The zone
also has the standard entry delay time provided that a delay
zone has been tripped first. If the premises are entered
without coming through a “delay”entrance, and a type [2]
zone is tripped, an immediate alarm will be generated.
[3] = Home-Away Zone operates the same as the type [2]
zone with the following exception. If the system is armed
and the delay zone is NOT tripped during the exit delay
time, the type [3] zone will be bypassed. Instead of the
interior portion of an interior Home-Away zone, a Home-
Away zone can have a delay equal to the standard entry
delay when section [17], light 5 is on. This will affect all
Home-Away zones when they are not bypassed by [✱][1],
[✱][9] arming, or by arming and not leaving the premises.If
Home-Away zones are automatically bypassed or [✱][9]
arming bypassed and the user then goes [✱][1], the Home-
Aways will then have a delay if the feature is enabled and
will be a type [2] zone if not.
[4] = 24 Hour Bell Zone is active at all times and will create
an alarm if the panel is armed or disarmed. This zone will
always activate the bell/siren output.
[5] = 24 Hour Bell/Buzzer operates as the type [4] except
the bell/siren output is activated only when the panel is
armed and only the keypad buzzer is activated while the
panel is disarmed.
[6] = 24 Hour Buzzer operates as the type [4] except only
the buzzer will be activated in the armed or disarmed mode.
[7] = Auxiliary Delay Zone operates the same as the type
[0] zone except the entry/exit times can be independently
set in section [21]. This zone type is useful when a zone with
an entry and/or exit time is required that is different from the
standard times as established for type [0] zones in section
[20]. If section [17], light 6 is on it will enable the system to
be armed even if the aux delay zone is open (“Ready”light
ON). Also, the system can be armed with the aux delay zone
closed and then it can be opened before the aux exit delay
has expired. In both cases the aux delay zone will not
become active until both the aux exit delay has expired and
the zone is closed. If force arming of type [7] zones is used,
quick exit must not be used.
