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.

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 Normally
Open(N.O.)alarm initiatingcontacts.Power wiring fromtheAUX +
/PGMterminalsshouldbesupervisedusinganRM-1relayafterthe
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
programmedviathe keypad. SeetheProgrammingGuide, section
[11].
Battery Connection
If the battery is reverse connected, the 5 A fuse will blow. 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.
IfACpowerisOFFandthebatteryvoltageisapproximately9.5Vor
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: Ensurethatplugsandjacksmeetthedimension,tolerance
and metallic plating requirements of 47 C.F.R. Part 68,
Subpart F.
WARNING
FCC restricts using this equipment on certain types of telephone
lines.Also,donotusethisequipmentonatelephonelineequipped
with a “call holding” feature, as the tone generated may interfere
with the communicator operations.
Do not connect the alarm panel communicator to telephone
lines intended for use with facsimile (FAX) machines. These
lines may incorporate a voice filter which disconnects the line
if other than FAX signals are detected, resulting in incomplete
transmissions.
Installation
Mounting the Panel

Auxiliary Power
Connection
The auxiliary power supply can be used
to power keypads, motion detectors and
otherdevicesthatrequire11VDC.Seethe
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
Guidesection[24]).DevicescontrolledbythePGMoutputmustbe

Guidelines for Locating Smoke Detectors
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
ofsmokeprecededetectablelevelsofheatinmostcases.Forthese
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
recommendedthatthesmokedetectormanufacturer'sliteraturebe
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.

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 the Alarm
and Restoral Codes section [09].
[F]ire Key Pressing the [F] key and holding it for 1 second will
initiate a local pulsing alarm and, if programmed, 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.

[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
usedby thecommunicatorwhentherehasbeenanalarmonzones
1 to 6.
Listed below are several programming examples and the resulting
transmissionusingdifferentformatsforthereportingcodes.Obtaining
differentformatsrequiresenteringdataintheAccountCodeSection
[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

[06] Zone Restoral Reporting Codes
These reporting codes are used by the communicator to transmit
zonerestoralsforzones1through6.Useinstructionsinsection[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
codes1to6.Ifpartialclosingisidentifiedinsection[14],thenalarm
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,ifthesystemisarmedanddisarmedbeforetheexpiryofthe
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]orusingtheAuto-Armfeature,accesscode#1willbetransmitted.
[08] Opening (Disarming) Reporting Codes
After Alarm Reporting Code
Thefirst 6 reportingcodes correspondtothe 6useraccess 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.
IftheAfterAlarmCodeisprogrammed,thatcodewillbetransmitted
to the monitoring station on opening if an alarm occurred during
previousarmedperiod. This featureisusefulforinstallationswhere
openings and closings are not reported normally, but it is desired
tohave a reporttothe monitoringstationon opening ifanalarm 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.
• Keypad [P]anic alarm.
• Keypad [F]ire alarm.
• Keypad [A]uxiliary alarm.
• Fire loop trouble restore.
• Keypad [P]anic restore.
• Keypad [F]ire restore.

[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],
option 5 is ON it will enable the system to be armed even if the
auxiliarydelayloopisopen(“Ready”lightON).Also,thesystem
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.

[11] Zone Definitions
As in the reporting codes sections, once this section is entered, 6
2-digitnumbers arerequired. Each2-digit numberentered 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
canbe set from10 msto990 ms.Thefactory defaultloopresponse
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
delaytimehasexpired,openingtheloopwillstarttheentrydelay
timer.Duringthe entrydelaytime, the keypadbuzzerwill 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.

Communications Compatibility
All these communication formats are compatible with the Silent
Knight model SK9000 and Ademco model 685 receivers.
10 BPS and 20 BPS Formats
10BPS is thestandardslow formatusedon Silent Knight/Ademco
receivers.DATA=1900Hz;KISSOFF=1400Hz;SPEED=10baud
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].TheextendedversionoftheRadionicsformatisnormallyused.
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. Thezonealarmreportingcodesmustallbesingledigitnumerical
codeswithnoextended2ndroundbeingsent (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
extended2nd round. The1st digitofthe reportingcodeis 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

13
•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 the [*][7] command, 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
smokedetectors(positivecomesfromtheAUX+terminal).To
activate this output (to reset smoke detectors), enter [*][7].
ThePGMterminalwillgohigh(opencircuit),andthusremove
power from the devices connected. The keypad buzzer will
sound for the 5-second period.
