Features
Keypad Programmable
The PC1550 is complete with a default program so that it is operational
with a minimum of programming. The control panel is completely
programmable from the keypad.
EEPROM Memory
The panel uses EEPROM memory which will retain all program
information even if AC and battery power are removed from the panel.
The EEPROM memory can be reprogrammed thousands of times.
Static/Lightning Protection
The PC1550 has been carefully designed and tested to provide reliable
protection against static and lightning induced transients. Our special
“Zap-Trac” circuit board design catches high voltage transients right
at the wiring terminals, and transient protection devices are placed in
all critical areas to further reduce damaging voltages.

Installation
Mounting the Panel
Select a dry location close to an unswitched AC source and close to the
telephone line connection. Remove the printed circuit board, the
mounting hardware and the keypad from the cardboard retainer inside
the cabinet. Before attaching the cabinet to the wall, press the four
white nylon printed circuit board mounting studs into the cabinet from
the back. Once the cabinet is mounted to the wall, pull all the cables into
the cabinet and prepare them for connection. Use a meter to test the
wiring for opens, shorts and grounds. Press the circuit board onto the
white nylon mounting studs. Complete all wiring to the control panel
before applying AC power or connecting the battery.
NOTE: SeetheControl PanelWiringDiagramontheinsideback cover
for more information.
Mounting the Keypad
Keypads should be located close to the designated “Entry-Exit” door(s)
and mounted at a height convenient for all users.
NOTE: Complete all wiring to the control panel before applying AC
power or connecting the battery.
Auxiliary Power Connection
The auxiliary power supply can be used to power keypads, motion
detectors and other devices that require 11 VDC. See the Fire Zone Wiring
section for the connection of 4-wire smoke detectors. The total load for
the auxiliary power output must be calculated for all devices connected
across the AUX +/- terminals and for devices connected between the
AUX + and PGM terminals. The output current cannot exceed 475 mA.
Allow 35 mA for each PC1500RK keypad connected to the panel.
PGM Terminal Connections
The PGM terminal is a switched negative output which can be
controlled by various programming options (See Programming
Guide section [24]). Devices controlled by the PGM output must be
connected between the PGM terminal, which is (-) and the Aux. (+)
terminal.
Bell/Siren Connection
Observe polarity when connecting siren drivers, sirens and polarized bells.
For UL installations, when a bell or siren is used for fire signaling with
a pulsed cadence, it must be connected between the AUX+ and BELL-
terminals. To maintain bell circuit supervision, do not connect more
than one device to the BELL- terminal. A fire bell or siren used for this
application must be UL Listed and have a current consumption of
400mA or less (e.g. Wheelock MT-12/24-R).
For UL installations you must use a BSM-100 (Bell Supervision Module)
to supervise the Bell circuit.
The following connections of this module refer to BSM-100 Installation
Instructions P/N# 29003252.
Input Voltage:
13.85VDC
Current Standy:
20mA with Buzzer
Active: 70mA

Wire Routing for Power and Non-Power Limited
All wiring entry points are designated by the arrows. All circuits are
classified UL installation power limited except for the battery leads
which are not power limited.
A minimum ¼” (7mm) separation must be maintained at all points
between power limited and non-power limited wiring and connections.
NOTE:Wire entry for power limited wiring must be separated by a
different entry access from non-power limited wiring
.
Keypad Functions
Introduction
The PC1500RK remote keypad provides complete information and
control of the PC1550 control panel. The panel can be fully programmed
from the keypad. The 6 zone lights provide alarm and status indication
for the alarm circuits. Each zone can be programmed to be a burglary
zone or a fire zone.
Master Code
This code is used to arm and disarm the panel, to reset the bells after
an alarm, program up to 5 additional codes using [✱✱
✱✱
✱][5], and to enter
other user functions using [✱✱
✱✱
✱][6]. The panel default program allows the
user to change the Master Code. The panel can be programmed, by the
installer, so the user cannot change the Master Code. The default
Master Code is “1234”. See [13] 2nd System Option Code.
2nd Master Code
A second Master Code can be programmed. This code can be
changed by the installer only, and is useful where there are multiple
panels in a complex. The 2nd Master Code may be used as a “Master
Key”. The default 2nd Master Code is blank.
Installer’s Programming Code
The default Installer’s Programming Code is “1500”. Using this code
and [✱✱
✱✱
✱][8], the installer can gain access to the system to enter panel
program information. This code can be changed by the installer.
Arming
Before arming the panel, close all protected doors and windows and stop
movement in areas covered by motion detectors. If the “Trouble” light is
on, check for the type of trouble ([✱✱
✱✱
✱][2]) and correct the fault condition.
If the “Bypass” light is on, insure that the zones bypassed are bypassed
intentionally, ([✱✱
✱✱
✱][1]). If the “Ready” light is not on, one or more zones are
open. The system can only be armed when the “Ready” light is ON. To
arm, enter a 4 digit access code. As each digit is entered, the keypad
sounder will beep. When the correct access code has been entered the
“Armed” light will come ON and the keypad will beep 6 times. If the
access code has been entered incorrectly, the keypad will sound one
long tone. Press the [#] key and enter the access code again.
Once the panel has been armed, exit through the designated entry/exit
door before the exit delay time expires. At the end of the allowed exit
time, all lights on the keypad will go out except the “Armed” light. The
Keypad Wiring
Up to three keypads may be connected in parallel. Do not connect
multiple keypads on the same keypad wire run. For Standby Loading
purposes, use a current draw of 35 mA per keypad. This represents the
panel in the disarmed state with two zones open.
Fire Zone Wiring
Any one of the 6 zones may be programmed as a Fire Loop. See
Programming Guide section [11].

Smoke detectors should be the latching type and
have N.O. alarm initiating contacts. Power wiring
from the AUX + / PGM terminals should be
supervised using an RM-1 relay after the last
smoke detector. The RM-1 N.O. contacts (closed
with power applied) should be wired in series with
the alarm initiating end-of-line resistor so that
should power to the detector(s) fail, a fire loop
trouble will be initiated.
Burglary Zone Wiring
Burglary zone definition, (eg. Delay, Instant, 24 Hr. etc.) is programmed
via the keypad. See the Programming Guide, section [11].
AC Power Wiring
Complete all wiring to the control panel before connecting AC power or
the battery. Do not plug the transformer into an outlet that is controlled
by a switch.
Battery Connection
If the battery is reverse connected, the 3 A PTC will open. The battery
charging voltage is factory set and normally needs no adjustment. If the
battery charging voltage is out of adjustment, contact your service
representative.
NOTE: The battery charging voltage must not be adjusted on UL-listed
systems.
If AC power is OFF and the battery voltage is approximately 9.5 V or
lower, the battery will be disconnected and the panel will power down.
To power up again, the AC will have to be re-established.
Telephone Line Wiring
NOTE: Ensurethatplugsandjacksmeet thedimension,toleranceand
metallic plating requirements of 47 C.F.R. Part 68, Subpart F.
WARNING
FCC restricts using this equipment on certain types of telephone lines.
Read FCC Compliance Statement at the end of this manual. Also, do not
use this equipment on a telephone line equipped with a “call holding”
feature, as the tone generated may interfere with the communicator
operations.
NOTE:Do notconnectthealarmpanelcommunicatortotelephonelines

“Bypass”light will be ON if a zone is bypassed and if Show Bypassed
Status While Armed is programmed in section [31], zone light 4 ON.
See [17] System Times for instructions on changing the Exit Delay time.
Auto-Bypass/Home-Away Arming
Interior zones can be programmed as Home-Away zones (section
[11]). This means that when a correct access code is entered, and you
donot
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. This is a convenience feature for the user who wishes to
remain at home with the system armed.
To reactivate the interior zones that have been automatically bypassed,
press [✱✱
✱✱
✱][1]. The “Bypass”light will go out. If the bypassed zones were
programmed as Home-Away with delay, the “Bypass”light will go out after
the delay. This command is a quick method of fully arming the system
before going to bed and is useful for the user who has a keypad outside
areas protected by interior zones.
Arming Without Entry Delay
To eliminate the Entry Delay, arm the system using [✱✱
✱✱
✱][9] [ access
code]. An exit may be made as in normal arming. The system will arm
as described above in Auto-Bypass / Home-Away arming whether an
exit is made or not. The “Armed”light will flash to indicate that the
system is armed without the entry delay.
Disarming
Enter the premises through the designated entry-exit door. The keypad
sounder will be on as a reminder to disarm the system. Go to the keypad
and enter a valid access code. If an error is made entering the code,
press [#] and enter the correct code. The “Armed”light will go out and
the sounder will stop. The correct access code must be entered before
the entry time expires or the panel will go into alarm. To change the
entry time see section [17] System Times.
If an alarm occurred while the panel was armed, upon disarming the
“Memory”light and the zone light(s) of the zone(s) that caused the
alarm will flash for two minutes. Pressing [#] will stop the flashing,
extinguish the zone light(s) and return the panel to the ready mode. The
“Memory”light will stay on steady to indicate that an alarm did occur
during the last armed period. To view the zone(s) that caused the
alarm, see Alarm Memory Display [✱✱
✱✱
✱][3].
Zone Bypassing
[✱]+[1]
A bypassed zone will not be armed and will not sound an alarm. Use
zone bypassing when access is needed to part of a protected area or
if damage to contacts or wiring cannot be repaired immediately. The
panel can be armed with one or more zones bypassed even if the
zone(s) are open. The “Ready”light will be ON and the “Bypass”light
will be ON if a zone is bypassed. A fire zone cannot
be bypassed.
Zone bypasses are automatically cancelled when the panel is disarmed.
NOTE: Any zone defined as 24 Hour Bell, 24 Hour Bell/Buzzer, or 24
Hour Buzzer can not be bypassed while that zone is violated. To
bypass a 24 Hour zone, the zone must be physically restored.
To Bypass Zones:
Enter [✱✱
✱✱
✱][1] - the “Bypass”light will start flashing.
Enter [zone number to be bypassed]; the zone light will come ON to
indicate that the zone is bypassed. To remove a bypass, enter the zone
number and the zone light will go OFF. Continue entering the zone
numbers for the zones you want bypassed. Press [#] to return to Ready.
To Recall Bypassed Zones:
Enter [✱✱
✱✱
✱][1][9]
This command will recall the last zone or group of zones that were bypassed.
This feature is useful if the same group of zones is bypassed regularly.
Bypass Disable:
The installer can program the panel to prevent the user from being able to
bypass certain zones. Lights for these zones will not come ON in response
to the bypass command. See Zone Bypass Mask (section [16]).
Trouble Conditions
[✱]+[2]
The PC1550 continuously monitors a number of trouble conditions. If
one of these conditions occurs, the keypad “Trouble”light will come ON
and the buzzer will sound two short beeps every 10 seconds. To silence
the buzzer, press [#]. The buzzer will stop but the “Trouble”light will
remain ON until the trouble condition is cleared. See section [10]
Maintenance Alarms and Restorals for a list of codes that can be
transmitted to the monitoring station.
To view the trouble condition, press [✱✱
✱✱
✱][2].
1.LowBattery.If the battery voltage is low, the battery is disconnected
or the battery PTC is open, a trouble will be displayed and can be
reported.
2. AC Failure. On loss of AC power, the “Trouble”light will come ON
immediately, but the keypad buzzer will not sound. The keypad
buzzer will sound if AC power remains off and the battery reaches
a low voltage. The delay before transmitting AC Fail can be
programmed from 1 to 255 minutes. See Programming Section [17].
3. PTC Failure - Bell / Siren or AUX Output. A trouble is displayed if
the Bell / Siren PTC is open. If the AUX output PTC fails, it will not be
displayed but will be transmitted if programmed to do so.
4.UnsuccessfulCommunicationAttemptIf the digital communicator
is unsuccessful at communicating with the monitoring station after
8 attempts at each phone number that is tried, a trouble is generated.
See section [15], Communication Variables. If a later attempt at
communication is successful, the trouble is cleared. The trouble can
also be cleared by pressing [#] to exit from the trouble view mode.
5.FireAlarmCircuitTroubleAn open circuit on the zone programmed
as a fire loop will initiate a trouble. See Zone Definitions section [11].
6.Loss of TimeonSystem Clock When the PC1550 is powered up or
reset, the internal time of day clock needs to be reset to the correct
time. The trouble will be cleared after entering the trouble view mode
and pressing [#] to exit. The trouble will also be cleared on any
attempt to set the time of day. See [✱✱
✱✱
✱][6] User Function Command
for setting the clock. Press [#] to return to Ready. NOTE: A trouble
will not be generated if both the test transmission and Auto-Arm
times are not programmed with valid times.
NOTE:
If [9] is pressed while in the trouble display mode, the most
recent trouble will be displayed on the zone lights. This trouble memory
is most useful as a diagnostic tool when installing and servicing the
PC1550. Press [#] to return to “Ready”.
Alarm Memory
[✱✱
✱✱
✱]+[3]
Alarms caused during the previous armed period are stored in memory.
To view these alarms, press [✱] [3]. The “Memory”light will flash and
the alarm(s) will be displayed on the flashing zone lights.
In addition to the last alarm memory, there are two history levels. After
entering the memory mode, pressing any key [0] to [9] will display the
two other levels of alarm history. Each time a key 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, and if there is an alarm in the 1st level, the
1st level is cleared and the contents moved to the 2nd level. The 2nd
level contents are moved to the 3rd level and the 3rd level contents are
discarded. The “Memory”light will be ON only if there was an alarm
during the previous armed period. Press [#] to return to Ready.
Downloading Call-Up Command
[✱✱
✱✱
✱]+[4]
This command is used to initiate a call to the downloading computer so
that the panel can be accessed by the computer. This command must
be enabled in section [14], option [ 2]. Sections [26], [27] and [28] must

[1] Setting the Clock
The System Clock is a 24 Hr. clock and times must be entered as 2-digit
numbers.
e.g. HH - 01, 02, .... 10, 11, .... 23, 24
MM - 01, 02, .... 35, 36, .... 58, 59
8:05 AM would be entered as 0805
1:30 PM would be entered as 1330
Setting the system 24 Hr. clock tells the system the time of day. If the
system is without power, (AC and battery), it cannot continue to keep
time. When the panel is powered up, the system clock must be reset.
If the time needs to be reset, then a trouble #6 will be indicated on the
keypad. (See [✱][2] System Trouble Display). Trouble #6 will not be
generated if the Test Transmission and Auto-Arm times are not
programmed with valid times. (9999 in these positions disables these
features - see Section [19]).
[2] Set Auto-Arm Time
The PC1550 can be programmed to arm at the same time each day. At
the selected Auto-Arm time, the bell will sound one short burst every 10
seconds for a one minute period if section [32] option [2] is off. The
keypad will also sound for one minute. If any key is pressed during the
1 minute warning period, Auto-Arming will be aborted. Auto-Arming will
be attempted at the same time the next day. To set the Auto-Arm time,
enter [✱✱
✱✱
✱][6][Master Code][2] then enter the hours and minutes as
described at the beginning of this section. This feature must also be
enabled (see item [5] below).
[3] For Future Use
[4] Quick-Arm
Pressing [4] while in the User Function Command mode will Enable (3
beeps) or Disable (one long beep) the Quick-Arm feature. With this feature
enabled, the panel can be armed by simply entering [✱][0].
[5] Auto-Arm
With this feature enabled, the panel will automatically arm at the same
time each day. The time is set in section [19] or [✱][6][Master Code][2].
[6] Door Chime
With this feature enabled, the keypad will beep 5 times when any zone
defined as delay, instant or auxiliary delay opens or closes. The Door
Chime feature does not operate on other zone definitions. Zone Bypass
may be used to eliminate beeping on zones where it is not wanted. The
Door Chime feature functions only while the panel is in the Disarmed
mode.
[8] Bell Test
Pressing [8] while in the User Function Command mode will sound the
bell/siren, the keypad sounder and turn on all the keypad lights for 2
seconds.
[9] For Future Use
[0] Installer’s Test
This feature facilitates final testing of the system and when enabled, the
bell/siren will operate for 2 seconds each time a zone is put into alarm.
Each zone should be tripped individually to avoid confusion about
which zone originates the alarm. To exit the Installer’s Test mode, arm
then disarm the panel.
NOTE:
The communicator will transmit all alarms and restorals. Disable
the communicator if this is not desired (section [12], option [1]).
Utility Output Command
[✱]+[7] or [✱]+[7]+[Access Code]
The Programmable Output (PGM terminal) can be programmed for
activation by a keypad command. This output can be used to operate
other devices such as door openers, special lighting, door strikes or to
reset smoke detectors. (Section [24], item 2, 3 or 4.) Depending on the
option chosen, the [✱][7] command may or may not require a subsequent
access code.
When the correct command is entered, the keypad sounder and the
PGM output will operate for 5 seconds.

Installer’s Programming Command
[✱]+[8]+[Installer’s Code]
The PC1550 is completely programmed from the keypad by using
commands in the [✱][8] section. See the Programming Section of this
manual. The default Installer’s Code is [1500].
Arming without Entry Delay
[✱]+[9]+[Access Code]
Entering [✱][9] before the arming code will arm the panel without the
entry delay on delay zones. Also “Home-Away”zones are automatically
bypassed. When armed using the [✱][9] command, the “Armed”light
will flash to remind the user that the system is armed without entry
delay. This command allows the user to remain at home and have an
instant alarm on the entry doors.
Arming For The Night
[✱]+[1]
To reactivate “Home-Away”zones that have been bypassed by arming
with the [✱][9] command, enter [✱][1]. When this command is entered,
the “Armed”light will continue to flash to remind the user that the Entry
Delay is not applied to the Delay Zones. Also, the “Bypass”light will be
shut OFF to indicate that the Home-Away zones are no longer bypassed.
Note that the [✱][1] command will not remove bypasses from zones
that have been manually bypassed.
Quick-Exit Command
[✱]+[0] when Armed
Entering [✱][0] when the system is armed will allow the user to exit the
premises through any delay zone without altering the status of the
system if the Quick-Exit feature is enabled (section [32], option [4]). For
2 minutes after [✱][0] is entered into an armed system, one and only
one delay loop may be tripped. Any additional activity on any other
active loop will cause that loop to begin its alarm sequence.
Quick-Arm Command
[✱]+[0]
Entering [✱][0] is accepted as a valid arming code if the Quick-Arm
feature is enabled. This command is often used when individuals are
required to arm the system but not disarm the system. This could be
used with home visitors in the case of a residential alarm system or for
junior employees and maintenance staff in the case of commercial
systems. See [✱][6] User Functions Command section, for enabling
and disabling the Quick-Arm feature.
Keypad Zones
[F] - [A] - [P]
There are three zones which can be activated with single key entries on
the keypad. For the [F], [A] and [P] keys to be functional for transmission,
they must be enabled by the installer in Alarm and Restoral Codes,
section [09].
[F]ire Key Pressing the [F] key and holding it for 1 second will initiate
a local alarm which will sound using the Temporal Fire Pattern or will
pulse the bell. Also if programmed, it will transmit the alarm to the
monitoring station. The keypad will sound a series of short beeps once
the panel has accepted the alarm.
[A]uxiliary Key Pressing the [A] key and holding it for 1 second will, if
programmed, transmit an Auxiliary alarm to the monitoring station.
There is no local alarm and no keypad lights will come ON when this key
function is activated. The keypad will sound a series of short beeps
upon successful completion of the transmission to the monitoring
station.
[P]anic Key Pressing the [P] key and holding it for 1 second will, if
programmed, send a transmission to the monitoring station. The alarm
signal can be programmed to be
audible
or
silent.
See Programming
Section [12], option [6]. If programmed as
audible,
the local bell / siren
will sound steadily.
Keypad audible annunciation for the [P] key is programmable, Section
[14], option[5], for feedback (3 beeps) or silent (no buzzer feedback).
If programmed for
audible,
the buzzer will sound once the key input
is accepted.
Programming Guide
Introduction
The essential information which defines the operation of the control
panel is stored in a section of the EEPROM memory which is
accessible using the Installer’s Programming code or via downloading.
If the Installer’s code is forgotten, the EEPROM may be reset to the
factory default code. See Section [30], Reset to Factory Default.
Programming
With the panel in the disarmed mode, enter [✱][8][1500]. The panel can
only be programmed while it is in disarmed mode. The default installer’s
code is 1500; it can be changed in section [20], New Installer’s Code.
Once the installer’s command is entered, the “Armed”light will come ON
steadily and the “Memory“, “Bypass”and “Trouble”lights will flash. This
indicates that the panel is ready for programming.
NOTE: If no key entry is made for 2 minutes, the panel will return to the
Ready mode and installers programming will have to be re-entered.
With the “Armed”light ON steadily, enter 2 digits for the section you wish
to program. Section numbers range from [01] to [36], and each section
can be programmed independently. Section [00] is reserved for binary
programming which is normally done on instruction from factory technical
personnel.
Once the 2 digits for the section you wish to program are entered, the
“Armed”light will go OFF, the “Ready”light will go ON steadily, and the
keypad sounder will beep 3 times. The keypad is now ready to accept
data for the selected section.
Most sections contain groups of 2-digit entries and the keypad buzzer
will beep twice after each 2-digit group is entered. When the section is
first entered, the first 4 zone lights will indicate, in a binary format, the
value of the first digit in that section (see binary display section on this
page). If you wish to change that digit, simply enter the new digit from the
keypad. If you wish to keep that digit unchanged, you can enter the same
number or skip the digit by pressing the [F] key. Once the first digit has
been entered or skipped, the 4 zone lights will display the value of the
second digit. After each digit is entered or skipped, the zone lights show
the value of the next digit in the binary format.
When the required data for the section being programmed is completely
entered, the keypad sounder will beep several times and the “Armed”light
will come ON to indicate that the expected data has been entered. At this
point, you will still be in the program mode and need only enter the section
number for the next section you wish to program.
It is not necessary to program all 2-digit pairs in any given section. A
section can be entered and selectively programmed by going only to the
digit(s) you wish to change and then pressing [#] to return to the
programming mode. For 2-digit pairs, both digits must be programmed
before pressing [#]. Only the data entered before pressing [#] will be
changed in the EEPROM.
Program Data Review
•Enter the section you wish to program by entering the 2-digit
section number.
•The first 4 zone LEDs will represent the value, in binary 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 will beep several times and
then return to the program mode so that another section can be
selected for review or programming.
NOTE: Only sections [01] through [24] and [26] through [28] can be
reviewed using the method described above. Section [25] cannot be
reviewed.
Sections [12], [13], [14], [16], [31], [32], [34]
These sections use the zone lights to indicate which functions are
active and which number key to press to turn them ON and OFF. When
one of these sections is entered, zone lights 1 to 6 will display which
functions are currently ON. Pressing the key number corresponding to
the zone light number will toggle the function ON and OFF; the zone
light will turn ON or OFF to indicate the state of the function. All functions

7
can be turned OFF at once by pressing [0]. When the correct selections
have been made, press [#] to save the selections in memory and return
to the program mode.
Binary Data Display
Zone lights 1 through 4 are used to display the value, in binary format,
of the data as shown in the table below.
HEX Data Programming
Certain programming entries may require the entry of data in HEX
(hexadecimal, or base 16) format. HEX numbering uses the digits 0
through 9 and the letters A through F.
The letters A through F are represented by the number keys 1 through
6. To enter data in HEX format, first press [✱]. The “Ready”light will
flash. Enter the HEX value, then press [✱] again to return to the normal
entry mode. The “Ready”light will stop flashing.
To enter HEX numbers:
A➤Enter [✱][1][✱]D➤Enter [✱][4][✱]
B➤Enter [✱][2][✱]E➤Enter [✱][5][✱]
C➤Enter [✱][3][✱]F➤Enter [✱][6][✱]
Enter [✱] beforeand aftereach digit. The last digit in each section does
not require the final asterisk ([✱]) to be entered.
Programming Sections
[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 first telephone number the Communicator will dial. See
Section [25], Communicator Call Direction.
After entering section [01] for programming, enter the telephone
number the same way you would dial it on a touch-tone phone. Press
[#] after the last digit to complete the telephone number programming.
A second dial tone search, as required in a PBX system, can be added
by programming a HEX ‘D’between the digits in the phone number
where it is required. To enter a HEX ‘D’, press [✱] [4] [✱].
Instead of a dial tone search, a pause of 4 seconds can be inserted
between digits in a telephone number.
Enter [✱, 2, ✱] to dial a ‘✱’(HEX ‘B’)
Enter [✱, 3, ✱] for a 4-second pause (HEX ‘C’)
The total number of digits, including dial tone searches and pauses,
must not exceed 16. Remember, press [#] to complete entry of the
telephone number. When complete, enter two digits to program another
section.
[02] 1st Account Code
The 1st Account Code is always transmitted to the 1st telephone number
to identify the customer. Enter a 4-digit number. If the HEX digits ‘A’to ‘F’
are required, remember to enter [✱] before and after the digit entry.
Where a zero is required in the account code, enter HEX ‘A’(✱, 1, ✱)
to transmit 10 pulses which will be interpreted as a zero by the
monitoring station receiver.
If a 3-digit code is required, as in 3/1 formats, enter [0] as the LAST
digit. The [0] represents a null digit where no pulses are transmitted.
[03] 2nd Phone Number
This is the second telephone number to which the communicator will
dial. See [01] for programming instructions.
[04] 2nd Account Code
The second account code is always transmitted to the 2nd telephone
number. See [02] for programming instructions.
[05] to [10] Reporting Codes
These sections 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, no
transmission will be sent when an event takes place (i.e. alarm, restoral,
opening / closing, trouble, etc.). To prevent a transmission from being
sent for any event in the following sections, leave it unprogrammed or
enter [00] as the reporting code.
Section [05] and [06] each have 6 reporting codes. Sections [07], [08]
and [10] each have 7 reporting codes, while section [09] has 8
reporting codes. Once a section is entered, the system expects a
series of 2-digit numbers to be entered. The keypad beeps twice and
the “Armed”light flashes after each 2-digit entry. After the last 2-digit
number is entered, programming of the current section is complete.
The keypad gives a series of beeps, the “Ready”light goes OFF and
the “Armed”light comes ON. The keypad is then ready to accept the
next 2-digit section number for programming.
When changing reporting codes in a section, you can scroll to the code
you wish to change by pressing the [F] key. Only codes actually
changed will be altered in the EEPROM. Press [#] to exit from the
programming sequence.
[05] Zone Alarm Reporting Codes
Once Section [05] is entered, the panel expects 6 2-digit numbers for
the Alarm Reporting Codes for zones 1 to 6. These codes are used by
the communicator when there has been an alarm on zones 1 to 6.
Listed below are several programming examples and the resulting
transmission using different formats for the reporting codes. Obtaining
different formats requires entering data in the Account Code Section
[02] or [04], the Reporting Code Sections [05] to [10], and the
Communicator Format Section [23].
3/1 FORMAT - Non-extended reporting requires:
•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 in section [23].
•Single line digit Alarm Reporting Code Section [05]
i.e. Enter [30] for single digit code 3 (0 = no pulses)
TRANSMISSION SENT: 123 3
4/2 FORMAT - Non-extended reporting requires:
•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 in section [23].
•2-digit Alarm Reporting Code in section [05]
i.e. Enter [31] for 2-digit code 31
TRANSMISSION SENT: 1234 31
3/1 FORMAT - Extended reporting requires:
•3-digit Account Code in section [02] or [04]
i.e. Enter 1230 for code 123
•Format Code [8], [9], [A], [B], [C] depending on
receiver type in section [23]
•2-digit Alarm Reporting Code in section [05]
i.e. Enter [31] for 2-digit code 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’or ‘FF’to disable that reporting code.
[06] Zone Restoral Reporting Codes
These reporting codes are used by the communicator to transmit zone
restorals for zones 1 through 6. Use instructions in section [05] above
as a guide for programming.
[07] Closing (Arming) Reporting Codes Partial
Closing Reporting Code
Reporting codes 1 to 6 are used to identify closings for access codes
1 to 6. If partial closing is identified in section [14], then alarm codes
for manually bypassed zones will be transmitted when the system is
closed with one or more zones bypassed.
When transmitting in 4/2, 3/1 or any other of the extended formats, see
section [05] above. The 6 closing codes are programmed as follows:
[C1], [C2], [C3], [C4], [C5], [C6]
Where the first digit HEX ‘C’represents a closing signal and the second
digit represents the user access code which was used to arm the
system (HEX ’C’could be any other number depending on what is used
at the monitoring station).
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 closing transmission will take place.
The partial closing code, if used, is transmitted in tandem with the
regular closing code to identify the closing as a partial closing.
When the system has been armed using the Quick-Arm command
[✱][0] or using the Auto-Arm feature, access code #1 will be transmitted.
[08] Opening (Disarming) Reporting Codes After
Alarm Reporting Code
The first 6 reporting codes correspond to the 6 user access codes.
When the system is disarmed using one of the access codes, the
corresponding reporting code in this section is transmitted. See
section [07] above for examples of reporting code programming.
If the After Alarm Code is programmed, that code will be transmitted to
the monitoring station on opening if an alarm occurred during 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 while the system was closed.
[09] Priority Alarms and Restorals
These reporting codes are used by the communicator to transmit the
following list of troubles, alarms and restorals. See section [05] as a
guide for programming.
•Fire loop trouble. •Fire loop trouble restore.
•Keypad [P]anic alarm. •Keypad [P]anic restore.
•Keypad [F]ire alarm. •Keypad [F]ire restore.
•Keypad [A]uxiliary alarm. •Keypad [A]uxiliary restore.
Transmission for operation of the [F], [A] and [P] keys will only take
place if the appropriate sections in [09] are programmed with a
reporting code.
[10] Maintenance Alarms and Restorals
These reporting codes are used by the communicator to transmit the
following list of alarms and restorals. See section [05] as a guide to
programming.
•Low battery alarm. •Low battery restore.
•AC failure alarm. •AC failure restore.
•PTC failure alarm. •PTC failure restore.
•Automatic Test Code
Test code is not transmitted if periodic downloading is selected,
section [14], light 3. For Automatic Test Code Reporting, the time
between reports (in days) must be entered in section [17] and the time
of day for the report must be entered in section [19].
NOTE: ForULinstallations,eitherACfailureorbatterytroublereporting
must be enabled.
[11] Zone Definitions
As in the reporting codes sections, once this section is entered, 6 2-
digit numbers are required. Each 2-digit number entered defines how
a zone will operate.
Zone Definitions Digit #1
The first digit determines whether the zone will cause a silent alarm or
an audible alarm and whether the zone response will be fast or slow.
Loop response time can be programmed in section [17] and can be set
from 10ms to 2550ms The factory default loop response time is 500 ms.
If set at fast, the loop response time is 10 ms, and if set at slow, the loop
response time is 500 ms or whatever time is set in section [17].
Digit # 1 Summary
[0] = slow & audible
[1] = slow & silent
[2] = fast & audible
[3] = fast & silent
Zone Definitions Digit #2
Digit #2 determines the zone type, [0] through [8], as described below.
[0] Standard Delay Loop 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 loop may be opened and closed during the delay time
without causing an alarm. After the exit delay time has expired,
opening the loop 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 loop are a 30 second entry delay
and a 120 second exit delay. The entry and exit delays may be
independently programmed in section [17] for periods from 001
second to 255 seconds. All loops programmed as type [0] will have
the entry and exit delays as programmed in section [17] or the
default times if section [17] is not programmed.
[1] Instant Loop 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 [17].
[2] InteriorLoopis normally used with interior motion detectors and has
the standard exit delay time. The loop also has the standard entry
delay time provided that a delay loop has been tripped first. If the
premises are entered without coming through a “delay”entrance,
and a type [2] loop is tripped, an immediate alarm will be generated.
[3] Interior Home-Away Loop operates the same as the type [2] loop
with the following exception. If the system is armed and the delay
loop is NOT tripped during the exit delay time, the type [3] loop will
be bypassed. Instead of the interior portion of an interior Home-
Away loop, a Home-Away loop can have a delay equal to the
standard entry and exit delay when section [32], light 3 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 enters [✱][1], the Home-Aways will
then have a delay.
[4] 24 Hour Bell Loop is active at all times and will create an alarm if
the panel is armed or disarmed. This loop will always activate the
bell/siren output, unless programmed as silent in digit #1 of the
zone definition.
[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] 24HourBuzzeroperates as the type [4] except only the buzzer will
be activated in the armed or disarmed mode.

[7] Auxiliary Delay Loop operates the same as the type [0] loop
except the entry/exit times can be independently set in section [18].
This loop type is useful when a loop with an entry and/or exit time
is required that is different from the standard times as established
for type [0] zones in section [17]. If section [32], light 5 is ON it will
enable the system to be armed even if the auxiliary delay loop is
open (“Ready”light ON). Also, the system can be armed with the
auxiliary delay loop closed and then it can be opened before the
auxiliary exit delay has expired. In both cases the auxiliary delay
loop will not become active until both the auxiliary exit delay has
expired and the loop is closed.
[8] FireLoopAlthough a common fire signal is reported, any one of the
6 zones may be programmed as a fire loop. A fire loop is a
supervised (N.O. alarm initiating contacts), end-of-line resistor
circuit designed to accept latching 4-wire smoke detectors. See
the Control Panel Wiring Diagram.
On alarm, fire loop shorted, the bell / siren will sound using the
Temporal Fire pattern or will pulse to indicate that a fire loop has
been activated. Transmission by the digital communicator is delayed
30 seconds. If the alarm is acknowledged before the 30 second
delay has expired, pressing [#] will silence the alarm and abort the
transmission. If the alarm is NOT acknowledged within the 30
second period, transmission will proceed and cannot be aborted.
If the alarm has been silenced and all smoke detectors are not
restored to normal, the alarm will re-sound after 90 seconds; 30
seconds after that, the communicator will transmit. If the alarm re-
sounds, it may again be silenced by pressing [#] and the
communicator transmission will be aborted if the alarm is silenced
within the 30 second transmission delay period. Temporal Fire
pattern is 0.5 sec ON, 0.5 sec OFF, 0.5 sec ON, 0.5 sec OFF, 0.5
sec ON, 1.5 sec OFF.
To restore smoke detectors to normal, clear all smoke from the
detectors and perform a reset by pressing [✱] [7]. See section [24]
for programming the PGM terminal for smoke detector reset.
Pressing [✱][7] will remove power from the smoke detectors for 5
seconds; if the detectors are clear of smoke, they will return to
normal. If the detectors still have smoke in them, the alarm will re-
sound and the sequence described above will repeat.
For an open on any loop programmed for fire, the “Trouble”light will
come ON and the keypad sounder will beep every 10 seconds. The
keypad trouble buzzer will sound and the “Trouble”light will come
ON regardless of whether the panel is armed or disarmed. The
communicator will transmit the trouble condition if programmed in
section [09]. The audible trouble indication may be silenced by
pressing [#]. The “Trouble”light will only go OFF when all the fire
loop troubles are cleared. To determine the type of trouble, press
[✱][2].

computer. The cycle time (in days) for the call is set in section [17].
The automatic call to the downloading computer can be used to
update the panel program and / or to upload status information from
the panel.
3If partial closings are enabled as identified, then alarm codes for the
bypassed zones will be transmitted.
[15] Communication Variables
Once this section is entered, two 2-digit numbers are expected. Do not
press [#] while entering data. The first 2-digit number defines the
number of attempts (alarm and restoral pairs) per zone that the
communicator will make before it shuts down for that zone (swinger
shutdown). The number of attempts is for the period as defined in the
1st System Option Code Section, zone light 2. The number of attempts
may be programmed from ‘00’to ‘99’, where ‘00’means the
communicator will never shut down. The fire zone cannot be shut down
- it always transmits.
The second 2-digit number defines the delay before transmission, for
zones defined as burglary zones only. 24 hour loops or the fire loop will
not be delayed. The time may be programmed from ‘00’to ‘99’seconds,
where ‘00’means no delay. NOTE:NOTE:
NOTE:NOTE:
NOTE: For UL installations, the Maximum
Transmissions section cannot be enabled. Also, the Delay Before
Transmission must not exceed 15 seconds.
[16] Zone Bypass Mask
Use the same method of programming as used in section [12]. If the
zone light is ON, the zone can be bypassed; if OFF, the zone cannot be
bypassed using [Q][1]. The fire zone cannot be bypassed.
[17] System Times
There are 6 system times which can be programmed in this section, and
each entry requires a 3-digit number. Do not press [#] during data entry.
[1] Entry delay time (001 to 255 seconds) This value determines the
standard Entry Delay time. The factory default entry time is 30
seconds. See Section [11] for zone definitions.
[2] Exit delay time (001 to 255 seconds) This value determines the
standard Exit Delay time. The factory default exit time is 120
seconds. For zone definitions, see Section [11].
[3] Bell cut-off time (001 to 255 minutes) This value determines the
time the bell / siren will sound before automatically turning off. The
factory default bell cut-off time is 4 minutes.
[4] AC fail transmission delay (001 to 255 minutes) This value
determines the length of time before the communicator will transmit
an AC failure report. The factory default time is 30 minutes.
[5] “Slow” zone response time (001 to 255 ×10 ms) This value
determines the “slow”zone response time and provides times from
10 ms to 2550 ms. The factory default “slow”zone response time
is 500 ms.
NOTE: The “fast”zone response time is fixed at 10 ms.
See Section [11] Zone Definitions.
[6] Test transmission cycle time (001 to 255 days) This value
determines the frequency, in days, of the test transmission either
via the communicator or by calling the downloading computer. The
factory default setting is 30 days. See Section [14] 3rd System
Option Code, light 3.
[18] Auxiliary Delay Loop Entry/Exit Times
This section requires two 3-digit entries to establish the Auxiliary Entry
and Exit Delay times. Do not press [#] during data entry. The default
Entry Delay is 45 seconds and may be changed to any time from 001
seconds to 255 seconds. The default Exit Delay is 120 seconds and
may be changed to any time between 001 to 255 seconds.
For auxiliary delay zone times to be effective, the zone must be
programmed as a type [7] in the Zone Definition Section [11].
[19] System Clock Times
This section requires two 4-digit entries to set the Automatic Arming
Time of Day and the Test Transmission Time of Day. Do not press [#]
during data entry. Factory default for both these times is ‘9999’; that is,

* See section [13] for Radionics handshake option.
Communications Compatibility
All these communication formats are compatible with the Silent Knight
model SK9000 and Ademco model 685 receivers. For UL installations,
ensure that the control unit is reporting to one of these receivers.
10 BPS and 20 BPS Formats
10 BPS is the standard slow format used on Silent Knight / Ademco
receivers. DATA = 1900 Hz; KISSOFF = 1400 Hz; SPEED = 10 baud
20 BPS is the standard fast format used on the DCI / Franklin / Sescoa and
Vertex receivers. DATA = 1800 Hz; KISSOFF = 2300 Hz; SPEED = 20 baud
Radionics Format
For conventional Radionics 3/1 format, the communications mode
should be set on either Radionics rounds [B] or Radionics parity [C].
The extended version of the Radionics format is normally used. The
following guidelines are provided to help in configuring the PC1550 for
Radionics format.
1. The customer account code must be only 3 digits with a zero
making up the 4th digit (i.e. Enter 1230 to program an account code
of 123).
2. The zone alarm reporting codes must all be single digit numerical
codes with no extended 2nd round being sent (i.e. Zone 1 = 10,
Zone 2 = 20... Zone 6 = 60). The zero in the 2nd digit position tells
the PC1550 not to send an extended round.
3. All other non-alarm reporting codes must be set up to send an
extended 2nd round. The 1st digit of the reporting code is used to
identify the event while the 2nd or extended digit is used to
associate the event with a particular item (i.e. A reporting code of
E3 means restore zone 3. E = restore, 3 = zone 3).
4. The following is a list of 1st digit identifiers that should be used with
the Radionics format.
Restorals “E”i.e. E3 = restore zone 3
Openings “B”i.e. B2 = opening by user 2
Closings “C”i.e. C4 = closing by user 4
Troubles “F”i.e. F5 = trouble from source 5
Miscellaneous “D”i.e. D1 = partial closing
[24] Programmable Output Options
PGM Terminal
The PGM output can be programmed in this section to operate in
response to various panel operations. The output pulse connects the
PGM terminal to the negative power rail.
[01] Ground Start Pulse
This option provides a 2-second output pulse before dialling
begins to obtain the dial tone on Ground Start telephone
equipment.
[02] Utility Output, no Access Code
When activated by entering [✱][7], the PGM output will go low for
5 seconds and the keypad buzzer will sound.
[03] Utility Output, any Access Code
The same as [02], except the command is [✱][7] [any valid
access code].
[04] 5-Second Reset Pulse
When this option is selected, the PGM output is normally low. That
is, it is just the reverse of all other options which are normally high
and go low when activated. This option is normally used as the
negative return for power to 4-wire smoke detectors (positive
comes from the AUX + terminal). To activate this output (to reset
smoke detectors), enter the [✱][7] command. The PGM terminal
will go high (open circuit), and thus remove power from the
devices connected. The keypad buzzer will sound for the 5-
second period.
[05] Courtesy Pulse
This option provides an output which follows the entry and exit
times. It can be used to turn on a courtesy light near the exit door
for the duration of the entry / exit times.
[06] Keypad Buzzer Follow Mode
The PGM output will go low as long as the keypad buzzer is ON
for “24 Hour Buzzer Zone”, “Door Chime”, “Entry Delay”and
“Auto-Arm Alert”.
[07] System Status (Armed / Disarmed)
The PGM output switches to and remains at ground as long as the
panel is armed. The output goes high (open) while the panel is
disarmed.
[08] Strobe Output (Latched Alarm Output)
The PGM switches to ground on an alarm and remains low until
the panel is disarmed. It can be used to indicate that an alarm has
occurred before entering the premises.
[09] Failure to Communicate
The PGM output switches to ground if the systems fails to
communicate after 8 attempts to each phone number that will be
tried according to the communicator call direction options. The
output remains low until a successful communication takes place
or until trouble #4 is cleared from the keypad. This option can be
used to tie two systems together so that if one fails to communicate,
the other system will report the failure.
[0A] PGM ON during Entry Delay
The PGM output will be switched on for the duration of the Entry
Delay. This option may be used to provide lighting in the entrance
area, or to activate a device when the Entry Delay begins.
[0B] PGM ON during Exit Delay
The PGM output will be switched on for the duration of the Exit
Delay. This option may be used to provide lighting in the exit area,
or to activate a device when the Exit Delay begins.
[0C] LINKS1000 Interface
This option configures the system for use with the LINKS1000
Cellular Alarm Communicator. Refer to the LINKS Installation
Manual for further programming instructions.
[25] Communicator Call Directions
This section requires four single digit entries using digits 0 to 3 only.
This section defines how the communicator will call the telephone
numbers programmed in sections [01] and [03] to report the following
events:
Zone Alarms and Restorals
Access Codes Openings and Closings
Priority Alarms and Restorals
Maintenance Alarms and Restorals
Enter ONE digit from the list below for each of the above categories.
Factory default = 1 for all 4 code groups.
[0] Disables the function (no transmission for the group)
[1] Call 1st phone number and back-up to the 2nd phone number
when section [13] light 1 is set to OFF and the panel has made
8 unsuccessful tries on the 1st phone number.
[2] Call the 2nd phone number only
[3] Always call both phone numbers
If [#] is pressed during data entry, you will be returned to the installer’s
programming mode and data for this section will NOT be saved.
[26] Downloading Telephone Number
This telephone number is used by the panel to call the downloading
computer when a request to call is make by entering [✱][4] or for an
auto-download. See section [14] 3rd System Option Code, lights 2 and
3. See section [01] 1st Phone Number for instructions on programming
the downloading telephone number.
[27] Downloading Access Code

12
This 4-digit code allows the panel to confirm that it is communicating
with a valid downloading computer. Enter 4 digits using the numbers
0 through 9 only. The factory default code is [1515].
[28] Panel Identification Code
This 4-digit code allows the downloading computer to confirm the
identity of the control panel. Enter 4 digits using the number keys 0
through 9 only. The factory default code is [1501].
[29] Number of Rings Before Answering
Section [29] is used to set the number of rings before the panel will pickup
and answer the call. See section [31] for information on using the panel
with an answering machine connected to the same phone line.
[30] Reset to Factory Default
Software
Entering [30] will perform a software reset to the factory default values.
Once this command is entered, the keypad buzzer will beep several
times. The “Trouble”LED will be ON during the reset sequence.
Hardware
If the installer’s code is forgotten and a software reset cannot be
performed, the panel can be reset to the factory default values with the
following method.
1. Remove all power, AC and battery, from the panel.
2. Short the pads on the panel labelled EEPROM RESET.
3. While maintaining the short, power-up the panel and wait for at
least 10 seconds before removing the short.
4. Upon removal of the short, the keypad buzzer will beep and the
panel will be reset to the factory default values.

This feature is enabled by entering [90] while in the installer’s programming
mode. A factory default (hardware or software) will not reset the installer’s
code or the download access code once this feature is enabled. A panel
that has this feature enabled will give a distinct audible indication upon
power-up. This indication is the phone line relay clicking 10 times. Make
sure that your new installer’s code has been entered correctly before
enablingthis featurebecause thereis noway ofre-entering theprogramming
mode without the new installer’s code. Remember that even a reset to the
factory default will not change the installer’s code back to the default.
NOTE:
Panels returned to DSC with the installer’s lockout feature
enabled and no other apparent problems will be subject to an additional
service charge.
[91] Installer’s Lockout Disable
Entering [91] when in the installer’s programming mode will disable the
installer’s lockout feature.
Guidelines for Locating
Smoke Detectors
Experience has shown that all hostile fires in residential units generate
smoke to a greater or lesser extent. Experiments using typical fires in
residential 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 dwelling.
The following information is for general guidance only. The smoke
detector manufacturer’s literature should be consulted for detailed
installation instructions.
On smooth ceilings, detectors may be spaced 9.1m (30 feet) apart as
a guide. Other spacing may be required depending on ceiling height,
air movement, the presence of joists, uninsulated ceilings, etc. Consult
National Fire Alarm Code NFPA 72, CAN/ULS-S553-M86 or other
appropriate national standards for installation recommendations.
•Do not locate smoke detectors at the top of peaked or gabled
ceilings; the dead air space in these locations may prevent the unit
from detecting smoke.
•Avoid areas with turbulent air flow, such as near doors, fans or
windows. Rapid air movement around the detector may prevent
smoke from entering the unit.
•Do not locate detectors in areas of high humidity.
•Do not locate detectors in areas where the temperature rises above
38oC (100oF) or falls below 5oC (41oF).
Smoke detectors should always be installed in accordance with NFPA
72, the National Fire Alarm Code. Smoke detectors should always be
located in accordance with:
•Paragraph 2-2.1.1.1 of NFPA 72: “Smoke detectors shall be installed
outside of each separate sleeping area in the immediate vicinity of the
bedrooms and on each additional story of the family living unit,
including basements and excluding crawl spaces and unfinished
attics. In new construction, a smoke detector also shall be installed in
each sleeping room.”
•Paragraph 2-2.1.1.2 of NFPA 72: “Split level arrangement. Smoke
detectors are required where shown. Smoke detectors are optional
where a door is not provided between living room and recreation room.”
