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 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 zone loops 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 loop 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.

Notice: Ensure that plugs and jacks meet the

dimension, 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. Read FCC Compliance

Statement at the end of this manual. Also, 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.

Terminal Connections

“AC” Power Terminals

Use a 16.5 VAC transformer with a minimum 40 VA rating

WWW.DIYALARMFORUM.COM

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 11 VDC. 400 mA 11

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 colored 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 11 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.

The keyswitch arming feature must be implemented using

a UL listed device.

”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 the smoke detector is not restored to normal after

signal has silenced, 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

WWW.DIYALARMFORUM.COM

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. Wait for the communication to

complete. Disarm panel and check with the monitoring

station to confirm the transmission. Perform additional

transmissions required by the monitoring station.

Check the “Trouble” light on the keypad. If it is on, press

[✱] then [2] to determine if there is a system trouble. The

“Trouble Display” section in “Keypad Commands” gives a

description of the different trouble conditions.

Instructing End-User

Fill out the system reference guide in the PC2550

Instruction Manual. Check off sections in the manual

which apply to the user’s system and make additional

notes if necessary.

Describe the system to an authorized user. Describe

arming and disarming procedures. Describe the basic

keypad functions. Assist the user in working through

examples of each type of command.

Provide user(s) with the Instruction Manual and instruct

them to read the manual to become familiar with the

system operation.

Instruct the user to test the system on a regular basis as

described in the Instruction Manual. The Master Code

should be changed from the default setting and recorded

in the Instruction Manual.

the [#] key. To determine the nature of the trouble, press

[✱][2]. (See the “Trouble Display” section.)

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]).

Note: For UL installation, zone inputs must be

terminated with normally closed initiating devices or

end of line resistors.

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: Ensure that plugs and jacks meet the dimension,

tolerance and metallic plating requirements of 47

C.F.R. Part 68, Subpart F.

For proper operation there must be no other telephone

equipment connected between the control panel and

the telephone company's facilities.

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.

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. The battery charging

voltage is factory adjusted for 13.8 volts 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.

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

WWW.DIYALARMFORUM.COM

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, NFPA standard 74 requires smoke detectors to

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 NFPA standard 74 be

consulted and 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]

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-

WWW.DIYALARMFORUM.COM

entered. Once 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.

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.

station

6 Bell circuit failure

7 Smoke detector zone 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.

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].

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.

4Telephone Line Trouble...Telephone Line Trouble...

Telephone Line Trouble...Telephone Line Trouble...

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.

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

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].

15 additional codes may be programmed. The zone

lights are used to indicate which of these codes are

already programmed (zone light on steady) and the one

which is currently being programmed (zone light is

flashing).

To program the second code, press [2] and zone 2

light will flash. Then enter a 4 digit code and the buzzer

will beep three times and zone light 2 will come on steady

indicating a programmed code.

To remove the second code, press [2] - the buzzer will

beep three times and zone light 2 will flash. Enter [✱✱✱

✱], the buzzer will beep three times and zone 2 light will

go out to show that the code has been removed.

Follow the instructions in

for programming or

removing any of the other additional codes.

To program access codes 9 to 16, press 9 to toggle

into the upper code region. Zone lights 1 to 8 now

represent access codes 9 to 16 (light 1 is code 9.... light

8 is code 16). The “Ready” and “Armed” LEDs will flash to

indicate that the user is in the upper programming region.

Program or remove access codes 9 to 16 as stated in 3

and 4 above. Press 9 again to toggle back down to the

lower region (access codes 1 to 8).

Do not try to remove the Master Code (1st code). The

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 23.

To successfully program or remove additional codes,

the panel must be put into the code program mode by

following step 1 followed by steps 3 or 4. Note that if no

key entry is made for 2 minutes the panel will go back to

the normal arm/disarm mode, after which step 1 must be

repeated to get back into the code program mode.

automatically extended to include the day (two digits

01.....31), the month (two digits 01.....12) and the year

(two digits...e.g. 91, 92, 93....etc.).

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

two 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”). A printer, if attached,

will not function if the communicator is disabled.

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”). If a printer is attached to

the panel, setting the clock must include the day, month

and year. e.g. HH: MM: DAY: MONTH: YEAR.

Auto-arm Time of Day

[✱]+[6]+[MASTER CODE]+[2]

Note: Auto-arm cannot be used for UL installations.

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 abort: Any key can be pressed to abort the

auto-arm sequence and silence the keypad during the

one minute pre-alert (this is the default condition).

•Auto-arm abort with code: If section [17] light 4 is on,

then a valid 4 digit access code is required to abort the

auto-arm sequence.

The auto-arm will be attempted at the same time the

following day. Any time an auto-arm is aborted 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.

Note: Auto Arm must be disabled on UL Listed

systems.

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.

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.

WWW.DIYALARMFORUM.COM

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. This command is

often used when individuals are required to arm the

system. These individuals will not be able to disarm the

system. This could be used with home visitors in the case

of a residential alarm or junior employees and

maintenance staff in the case of a commercial alarm.

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 must not be used when auxiliary delay zones

are force armed. Turn light 6 in section [17] off to ensure

proper operation.

Note: Quick exit shall not be enabled on UL listed

systems.

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.

DOWNLOADING

The PC2550 supports the DSC “downloading” package.

See the downloading manual for details on specific

capabilities.

There are several sections pertaining to the downloading

feature which must be programmed.

Section [27] - Downloading Access Code

A four digit code must be programmed into this section to

allow access to the control panel by the downloading

computer.

Section [28] - Panel Identification CodeSection [28] - Panel Identification Code

Section [28] - Panel Identification Code

A four digit code must be programmed into this section to

allow the downloading computer to identify the panel it is

communicating with.

Section [46] - Downloading Computer Telephone

Number

If Callback is enabled, section [47] zone light [8], then

this section must be programmed with the telephone

number of the downloading computer.

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

PROGRAMMING

GUIDE

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 LED’s 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] and [50] 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 [ ✱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] and [50])

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.

WWW.DIYALARMFORUM.COM

[07] Reporting Codes for Closing

(Arming) via 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) via Access Codes 9 to 16

The Auto-arm Abort Code is described on page 10 under

Auto-arm Time of Day. See section [07] for programming

information.

[09] Reporting Codes for Opening

(Disarming) via 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) via 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 Panic Restoral [P]

• 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].

The reporting codes are programmed in the following

order.

• Battery Trouble

• AC Trouble

• Day Zone(s) Trouble

• Bell Circuit Trouble

• Fire Zone Trouble

WWW.DIYALARMFORUM.COM

• Auxiliary Power Supply Trouble

• Periodic Test Transmission

Note: For UL residential installations, either AC failure

or battery trouble reporting must be enabled.

For UL commercial installations, both AC failure and

battery trouble reporting must be enabled.

[14] Zone Definition 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

# Not allowed for UL 7 = Auxiliary delay

local installations. 8 = Day

Notes: The maximum delays allowed for UL

residential installations are: Entry delay = 45 seconds;

Exit delay = 60 seconds.

The maximum delays allowed for UL commercial

installations are: Entry delay = 60 seconds; Exit delay

= 60 seconds.

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 ms 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

the time 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 45 second exit delay. The entry and

exit delays may be independently programmed in section

[20] for periods from 1 second to 99 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 45 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] = Aux. 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.

[8] = Day Zone

is a variation of a 24 hour circuit. It

operates as a type [5] zone by ringing the bell or siren at

night and the keypad buzzer during the day (2 beeps

every 10 seconds; pressing any key silences keypad

buzzer). However, a trouble transmission (programmed in

section [12]) is sent when the system is disarmed rather

than an alarm transmission (programmed in section [05]).

[15] 1st System Option Code

The 1st system option code is set using the zone lights to

indicate which options in the following list are active.

Once section [15] is entered the 8 zone lights will indicate

which options are active. Press the corresponding

number key to turn an option on or off. Press [0] to turn

all options off.
