1. Introduction
The ENIGMA XM88422 is a multi-line, multi-format
digital receiver for commercial fire and burglary
monitoring. The standard unit consists of a CPM
Central Processing Module, a DLCM Dual Line Card
Module and a PWR Power Module. With additional
Dual Line Card Modules, the receiver can be enabled
to monitor up to 30 telephone lines. The ENIGMA
XM88422 can receive and decode most of the
popular and commonly used communication formats.
See Appendix B. for details
The ENIGMA XM88422 stores all events with time
and date stamped. All information is displayed on the
large LCD screen, and the events may be printed
and/or forwarded to a computer. To ensure security,
all programming functions, including the adjustment
of the real time clock and date is password protected.
CPM Unit
The Central Processing Unit controls the operation of
the receiver. Along with its large graphical LCD
screen, the CPM Unit incorporates two serial and one
parallel interface for computer and printer interface.
The CPM Unit has two external inputs, one for
external acknowledge, and one for tamper
recognition. The CPM Unit also incorporates two
programmable outputs, which can be programmed to
follow different receiver status.
The CPM Unit features a 4096-event non-volatile
memory buffer. The contents of the buffer may be
browsed on the LCD screen. If the printer or
computer is off-line, the CPM Unit will retain the
incoming events in its buffer, and will automatically
forward them, when the connection restores.
The CPM Unit has a large graphical LCD display
which enables the CPM to implement unique, user
friendly features like changeable display font sizes,
and pull-down menus and dialog boxes for
programming.
Line Cards
Each Dual Line Card Module contains two
independent Line Cards and each Line Card can
monitor a telephone line. The Line Cards contain a
1600-event event memory to record events and caller
information. Caller Identification capability is built-in
and the telephone number of the calling party can be
displayed, printed, stored in memory and forwarded
to the automation computer. The Line Cards also
support the 2-way audio listen-in.
The Line Cards are continuously supervised by the
CPM Unit to ensure uninterrupted communication.
Any trouble conditions are immediately reported on
the LCD screens and printer and/or forwarded to the
computer. The Line Card Module also verifies the
communication with the CPM Unit. In case of CPM
malfunction the operator will be advised with an
audible indication and the Line Cards will continue to
function in stand-alone mode, with their individual
LCD displays and controls. Each Line Card will
continue receiving events and store them in its buffer.
The events will be forwarded to the CPM Unit after
the connection restores.
Power Module
The Power Module supplies the power for the other
modules in the receiver. It requires 16.5 VAC from a
115 or 230 VAC, 50/60 Hz, transformer. The Power
Module is equipped with automatic battery charger
and backup battery connections. In case of AC failure
the Power Module automatically switches to backup
battery power. The backup battery capacity can be
between 7 and 15 Ah. The Power Module supervises
the presence of the battery and the battery capacity
and the current status is reported to the CPM Unit.
Compatibility
The ENIGMA XM88422 Digital Receiver is
compatible with the most commonly used automation
software packages. The receiver has been tested
with the following software:
Alarm SyS
SIMS II
Microkey SIS
For other automation software, generally, it can be
used with selecting the Surgard interface.

Instruction Manual
Introduction to Operation
Please, refer to the following chapters of this manual
to help you through the installation and operation of
the ENIGMA XM88422 digital receiver.
Chapter 3. Installation
Chapter 4. CPM Module
Chapter 5. Line Card Module
Chapter 6. Power Module
Bench Testing
It is highly recommended the receiver be tested
before commencing the actual installation, becoming
familiar with the connection and setup of the device,
and the receiver programming to make the final
installation more straightforward.
The following items are required for testing:
16.5V AC transformer
12V 6Ah battery with cables
2 telephone lines
a digital communicator, dialer or a control panel
capable for communication
Connect the transformer to the AC input terminal on
the backplane of the Power module. Connect the
battery cables to the BAT terminals with correct
polarity, but do not connect the battery to the cables
yet. (Note, that for connecting the transformer and
battery, you may have to disconnect the intercom
cable temporarily, and plug it back again after the AC
and battery connections have been made.)
Power Up
Powering up the unit starts with applying AC power to
the unit. After that, connect the battery to the battery
cables. The CPM unit carries out a comprehensive
memory test on power-up, which can take some time.
A counter in the upper-left corner of the CPM display
will count down during the memory test. If the CPM
finds any unreliable memory during the memory test,
it will stop, and display the faulty memory address on
the screen.
After the memory test had been finished, the CPM
resets the line cards. (The line cards may also reset
on power-up, and during the memory test they
display CPM error –it is normal, wait until the CPM
resets the line cards after memory test). The line
cards will beep, and their LCD display will show line
trouble condition, if no phone lines are connected to
the appropriate line inputs on the line card backplane.
The CPM unit displays the list of trouble and restores
condition occurred since powering up the receiver. If
no computer with proper automation software is
connected the COM1 port of the receiver, the CPM
will beep after encountering the COM1 error condition
waiting for manual acknowledge. Pushing the OK
button on the CPM unit can silence the buzzer.
Operation with the default programming
Without any changes to the factory default
programming, the receiver operates normally with the
following specifications:
Default Program Access Password is 1234 (right-
left-down-up)
Line cards answer to incoming calls on the first
ring
Caller identification is disabled
The handshake sequence is 2300,1400,dual tone
and FSK answer tone
Handles all formats except for 3/2, 3/1+Chk and
Surgard DTMF 4/3+Chk. These formats can be
enabled with programming.
Reception of Extended formats is disabled
Two Way Audio (listen in) is disabled
The printer operates in backup mode –prints
only events cannot be reported on COM1
If no computer connected, the events can be
acknowledged, and the buzzer silenced by
pressing the OK button on the CPM. The manual
acknowledgement will be registered with time
and date

Tamper recognition is disabled
The signals will be displayed on the LCD of the Line
Cards as they are received. After the Line Card
acknowledged the event to the control panel, the
event will be displayed on the LCD screen of the
CPM Unit with time and date. Events coming in
Contact ID and SIA format are automatically decoded
from the predefined event libraries. For other formats,
only the incoming code will be displayed. The events
will be reported to the computer via the serial port
COM1 and printed, if the computer is absent.
If the computer is not connected, pushing the
ENTER/ACK button will silence the buzzer. The
manual acknowledgement is recorded with time and
date.
Return to the default programming
You can return to default programming at any time by
entering the menu and selecting the ‘Factory
Defaults’ menu point from the ‘Utils’ menu.
If by any means you forget the password, then it is
not possible to enter the menu any more. In this
case, the following procedure can be done to restore
default settings:
1. Turn off the receiver
2. Dismount the CPM module. (see ‘Removing
and Installing Modules, p. 11)
3. Open the bottom cover of the module
4. Take out the data EPROM from the memory
card. Do not mount the cover back this time.
5. Remount the CPM module
6. Turn the receiver on and wait a few seconds.
7. Turn it back off again
8. Dismount the CPM module
9. Replace the data EPROM and close cover.

3. Installation
Mounting the Receiver
The ENIGMA XM88422 receiver is shipped by default
with a standard 3HE 19” desktop housing. The
housing can be extended using rack extender
brackets to 6 HE or more enabling the receiver to
build in additional Line Cards. Optional 19” rack
mounting brackets can be used to install the receiver
in standard 19” rack housings.
The LCD screens on the receiver are designed to be
viewed below eye level. If the receiver has to be
mounted above eye level, it is suggested to angle the
unit downward to improve visibility.
The following items can be supplied for installation:
19” rack extension kit for extra modules with
interconnect cables and 2 blank cover plates.
Extra Line Card Modules (shipped with
backplanes and mounting material)
19” rack mounts for mounting in cabinets
16.5V AC transformer (230V 50Hz version only)
Printer Connections
Any Printers equipped with a parallel Centronics
interface can be connected to the ENIGMA XM88422
receiver. To connect the printer to the receivers
parallel printer output use a parallel printer cable.
IMPORTANT: Using parallel printer cable with only
one common ground wire is not recommended.
Computer Connections
Connect the automation computer to the ENIGMA
XM88422 serial COM1 port using the supplied serial
cable. If the supplied cable is not long enough, a
standard serial AT Modem cable can be used up to
15 meters in length.
IMPORTANT: Do not use a null modem cable. Null
modem cables can only be used to connect other
receivers to the COM2 port of the ENIGMA.

Telephone Line Connections
Connect the telephone lines to the Line Cards LINE
modular jack with RJ11 4/6 pin modular cables. For
ISDN connection, use the 2 analog outputs of the
ISDN NT box.
The handsets for 2-way audio listen-in can be
connected to the modular jacks labeled HANDSET.
Ensure, that the handsets connected are off-hook,
because leaving the handsets on-hook will terminate
2-way Audio Mode. Measure the impedance of the
handsets to check, if the line will be terminated with
the proper impedance when switching to the handset.
On normal telephone lines, it should be around 600
ohms. When used in PBX system 2-way audio
communication needs bridging resistors with the
same value as measured on the handset. Using
improper termination the line will be dropped when
switched to 2-way Audio Mode
Grounding
To achieve the best resistance against static and
electric noise and electromagnetic interference (EMI)
connect the metal casing of the receiver to a
grounding point. Note that the grounding of the frame
has to be separate to the grounding of the Line Card
interfaces.
Proper grounding is essential also for the reliable
electric shock and lightning protection of the
telephone line interface of the Line Cards. Connect
the protective ground terminal of the Line Card
Module to a proper grounding point.
IMPORTANT: Do not connect the protective ground
terminals directly to each other, or to the metal frame.
Connect the terminals to the grounding pole
individually with separate wires. NEVER connect the
protective ground to the power/signal ground of the
receiver!!!

subrack housing.
Installation is the reversal of removal.
Install Additional Line Card Modules
To install new Line Card Modules to the system an
extension subrack with Line Card Module backplane
is required. The backplane is shipped with power and
communications bus extension cables.
To install the extension subrack with the LCM
backplane do the following:
Install the LCM backplane to the extension
subrack
Remove the top cover of the desktop housing
Mount the base subrack and the extension
subrack together with subrack extender brackets
Mount the top cover onto the top of the
assembly.
Connect the power cable to the receivers power
bus, but do not connect the communications bus
cable yet.
Push the new LCM module into its place, the
module will power-up.
Assign Line Card Numbers to the two line cards
in the module as described in chapter 5. Be
careful not to assign the same Line Card Number
for two line cards because that can cause system
malfunction.
Now connect the communications bus to the new
Line Card Module on the backplane with the
supplied cable.
The CPM will identify the new Line Cards,
receive and display their events.
Note, that when installing new modules, always assign Line
Card numbers to the Line Cards before connecting the new
module to the communications bus, otherwise the CPM
might fail to recognize the new Line Cards.

represent the individual events; the current event is
highlighted in the list of events with inverse display.
The display is as follows:
1234 Panic 01 02 06/20 15:40:02
In the first column, the account number is displayed,
in this case 1234. Account number 0000 represents
the service and trouble events of the receiver. The
special account number ??? signifies the fault data
events reported by the Line Cards in debug mode.
The account number can be up to 6 digits.
The second row shows the event information. The
event information can be different depending on the
incoming format, the preset and user defined
libraries. Examples for event information:
21
Normal event, code 21
Panic 01
SIA Event code NPA01
Burglary 01 005
Contact ID code E13001005
Custom Event 01
User defined event in the user
library as “Custom Event 01”
The event information contains all data related to the
event such as group/partition and zone/user
numbers. More about preset and user define libraries
in the Libraries section.
The third column displays the number of the Line
Card, from which the event was received. The Line
Card numbers can be between 01 and 1E. Number
00 represents CPM service events and events
coming from the COM2 RS232 serial port.
The fourth column contains the time and date of the
event. Every event, including the service and trouble
events of the receiver and the manual acknowledge,
are stored in the memory buffer with time and date
stamped. That allows the receiver to forward the
events to the computer (with Clock Signal Protocol)
and printer with the real time and date of the event,
even if the message is forwarded later.
Review the List of Events
The list of events can be reviewed with the use of the
directional buttons. Pressing Up and Down will move
the highlighted cursor backwards and forwards in the
list, allowing to view the contents of the memory
buffer.

Note, that incoming events have priority over
browsing, so that an event reception will
automatically interrupt review mode, and return to the
bottom of the list, with the newly received event
highlighted in the last line.
Change List Font Size
Pressing the Shift button will change between normal
and extended display font sizes. The change is
instant; the list of events and the status row will be
displayed in the selected font size.
Note, that after changing font size the list of events
will only display the last event received. Reviewing
previous events is possible through browsing the list
of events with the Up and Down buttons.
Receiver Status Information
The receiver status can be displayed by pressing the
Info button. A dialog box will appear with essential
information:
1234567890ABCDEF0
Line Cards: ooooooooooooooooo
oooooooooooooooo
Receiver: NORMAL OPERATION
Power Status: POWER OK
COM1 Status: ABSENT
Printer: ONLINE (BACKUP)
Memory Info: 0014/0014/0000
The upper part of the dialog box shows the Line Card
registration and status. The small boxes correspond
the Line Cards in the system by the Line Card
numbers. An empty box means, that no Line Card
detected at the given Line Card number. A filled box
means that the Line Card is detected, and the
connection via the internal communications bus is in
order. A crossed box means, that the Line Card was
detected, but the connection is broken –the Line
Card is broke down, or the Line Card Module was
pulled out.
Below that, the operating mode of the CPM Unit is
displayed. It should display “Normal Operation”. Next,
the status of the power supply, the status of the
RS232 serial port COM1 is displayed, and the status
and operating mode of the printer.
In the bottom line of the dialog box, the status of the
memory buffer is displayed. The numbers displayed
represent the event, the reporting and the printing
pointers of the memory.
Pressing the Enter or Clr buttons will return to the list
of events. If no key is pressed for one minute, the
dialog box will disappear automatically.
Protected Mode Operation
In protected mode, the receiver is operating the same
way as in normal mode, except that the menu and
local programming functions are accessible. A small
key displayed in the status row indicates protected
mode operation.
Note that not all the CPM parameters can be
programmed locally. Some of the parameters can
only be programmed by the user with the ENIGMA
Programmer Software via the serial ports, and some
of the parameters can only be changed by the
recommendation of an ENIGMA.
IMPORTANT: The menu and the local programming
functions have priority over the incoming events to
ensure problem free local programming of the
receiver. This also means, that the received events
will not be displayed and so the operator will not be
notified if the menu or dialog boxes are active. To
avoid unnecessary delay in processing received
events enter this mode only if necessary, and leave
the menu immediately after programming. For this
reason remote programming of the receiver is
suggested instead of local programming.
NOTE: If entered in protected mode and the menu
and local programming is not started in 30 seconds,
the receiver will automatically return to normal
operation
Entering Protected Mode
Entering protected mode is possible by pressing the
Func button and entering the proper password. Since
no numeric keypad is provided on the CPM Unit, to
enter the password, the buttons on the front panel of
the CPM Module can be used. The keys correspond
to the following values:

The Menu
By pressing the Menu button the menu is started.
Through the menu, the utility and local programming
functions can be accessed. The menu starts at the
main menu bar in the top of the screen.
Navigation in Menu
To navigate through the menu options the directional
buttons can be used. To enter a submenu or select a
menu item, press the Enter/Ack key. To step back
press Clr. Pressing Clr at the main menu bar will exit
the menu mode. The menu structure can be found in
the Appendix A.
WARNING: When the menu is active it has priority
over the incoming event messages. Exit the menu
immediately after the necessary changes have been
made to the receiver program to avoid unwanted
delay in message display.
Utilities and Local Programming
Through the menu, it is possible to access receiver
utility and local programming options. The available
commands are shown in the menu structure
Resend Events
The receiver stores the last 4096 events in the
memory even after it had reported to the computer or
printed. The Resend Events command will force the
receiver to send the contents of the memory buffer to
the central station computer regardless that the
events were reported before or not. (Memory flush)
Reprint Events
This command works the same way as the Resend
Events command, except that it sends the contents of
the memory buffer to the printer.
Receiver Status
This command will display receiver status in a dialog
box. The receiver status display can also be
accessed by pressing the Info button in normal
operating mode. The contents of the dialog box are
detailed in the System Status Information section
before.
Reset Receiver
This utility command allows the central station
operator to make a full receiver reset. This can be
useful if receiver malfunctions encountered. The
Reset Receiver command will make a warm-reset of
the receiver and will not change or destroy the
contents of the memory buffer and the user defined
libraries.
Erase Memory
This command is also can be used to reset the
receiver, but this command makes cold-boot, which
means, that the full power-on self-check sequence
will be executed and the contents of the memory will
be cleared. The user defined libraries will also be
destroyed, and have to be downloaded again.
Factory Default
This command makes a cold-boot with the factory
default parameters restored in the configuration
EEPROM. Use this command to reset the receiver to
the factory default state.
WARNING: Use the Erase Memory and Factory
Default commands with extreme caution because
these commands will erase the contents of the
memory buffer that may result data loss.
Date & Time
The real time clock of the CPM Unit can be set at this
option. A dialog box appears when selecting the
menu item:
Date: 98/06/20

Receiver Number
The receiver number identifies the receiver for the
computer. This is important when multiple receivers
are connected to a computer. The value can be set
between 0 and 256. The default value is 01.
Heartbeat
Defines the interval of the heart-beat signals sent by
the receiver to the computer to verify the serial
connection. The interval can be set between 01 and
256 seconds. Programming 0 will disable the heart-
beat signals if the automation software is not
compatible with heart-beat protocol. The default
value is 30 seconds.
Clock Signal
The insertion of the Clock Signal Protocol can be
turned on and off here. The Clock Signal Protocol is
used to transmit time and date information together
with the event to the computer. The default setting is
off. The Clock Signal Protocol can also be
programmed to transmit the year or the second of the
event (S or Y). The default is to transmit the second
of the event.
Printer Mode
The operating mode of the printer can be selected.
The three options are:
NORMAL
All the events will be printed,
regardless of the status of COM1
BACKUP
only the events failed to report on
COM1 will be printed.
OFF
nothing will be printed.
The default setting is OFF.
External ACK
The operation of the external Acknowledge input of
the receiver can be enabled and disabled here. When
enabled, the events can be manually acknowledged
by a normally open pushbutton connected to the
external Acknowledge input of the receiver. The
default value is disabled.
Tamper Check
When enabled, a short between the receivers tamper
inputs will generate a “Receiver Tamper” status
event. This can be used to record receiver tampering,
when the receiver is installed in a closed cabinet with
access doors. The default setting is disabled.
Buzzer Mute
This option can silence the buzzer for debugging or
servicing purposes. Enabling this option is not
recommended for central monitoring stations,
because the receiver will not beep when an event
comes in and the serial connection is broken. The
default setting is disabled.
HotSwap Mode
This option is active when the receiver is used as a
hot backup for another ENIGMA. The default setting
is disabled.
LCD Contrast
The contrast of the LCD display can be set here. It
can be set from 0 to 15 (0Fh). The lower values
mean lighter display, larger values mean darker
display. The default setting is 8.
Line Card Setup
When Line Card setup is selected, a small dialog box
will appear where the number of the Line Card to be
programmed can be entered. Line Card numbers
between 01 and 31 can be entered, but the Line Card
number is valid only if the given Line Card is present
in the system.
If a valid Line Card number is entered, a dialog box
will appear with the parameters of the given Line

96
9600 baud
14
14400 baud
19
19200 baud
28
28800 baud
Databits and Parity
The ENIGMA receiver uses RS232 asynchronous
serial communication with the computer. The data
byte protocol for the asynchronous communication
can be set with these parameters.
One data byte transmitted is composed of the
following:
1 startbit
7 or 8 databits
even, odd or no parity
1 stopbit
From the above parameters, only the number of
databits and the parity can be set. The number of
start and stop bits is fixed at 1.
Programmable Outputs
The CPM has two programmable outputs. The
outputs can be programmed to follow different CPM
status. When selected, a similar dialog box appears,
where the PGM activation events can be set:
PGMx on COM1 fault: OFF
on Trouble : OFF
on AC fault : OFF
on Event : OFF
The currently selected field is flashing. Skip between
fields with the Left and Right buttons. Pressing the
Up button or the Down button changes the field
contents. After the fields are set correctly, press the
Enter/Ack key to save the set values. A “Program
Change” event will be recorded and the serial ports
will be initialized. Pressing the Clr button will exit the
dialog box without making any changes.
Activation on COM1 fault
The PGM will activate when the connection with the
computer through Serial Port 1 is broken. When the
communication is restored, the PGM will deactivate.
Activation on Trouble
The PGM will activate when receiver trouble occurs.
When the trouble condition is restored, the PGM will
deactivate.
Activation on AC fault
The PGM will activate when the AC power supply of
the receiver is disconnected or fails. When the AC
power is restored, the PGM will deactivate.
Activation on Event
The PGM1 will activate if there are reportable events
in the memory buffer. The PGM1 will deactivate as
the event has been reported to the computer through
COM1.
In case of PGM2, the last option is reserved for the
HotSwap Poll Signalling. Do not use this option
unless the receiver is used as a backup of another
ENIGMA.
The activation events are related each other with OR
function. That means, that if any of the programmed
status occurs, the PGM will activate.
Info
Short information on the receiver can be viewed at
this menu item. The receiver version number and the
contact information is displayed.

CPM Ports
The ENIGMA digital receiver is equipped with two
RS232 serial and one Centronics parallel port. The
two serial ports have some very important differences
in function. The port functions and operation will be
detailed in this section.
Serial Port 1 (COM1)
The Serial Port 1, or as referred shortly COM1, is the
main communication port of the CPM Unit. Its main
task is to establish communication and report events
to the automation software on the central station
computer as described in the Serial Communication
section.
The secondary task of this port is the serial
programming of the receiver (See The CPM Module,
Serial Programming). When programming the
receiver from the serial ports, the CPM Unit can be
operated normally and does not have to be switched
to protected mode. Therefore, serial programming of
the receiver is recommended if possible.
The speed and data byte protocol of the COM1 port
can be set at the Setup, Serial Setup, COM1 Setup
section of the menu, as described before in section
Serial Setup. The default setting is 9600 bps, 8
databits, no parity, 1 stopbit.
Serial Port 2 (COM2)
The Serial Port 2, or as referred, COM2 is the
secondary serial port of the receiver. In normal
operation, it can be used to receive serial protocols
from other receivers (E.g. SurGard or another
ENIGMA). All the events received on COM2 are
stored in the CPM as they would received on the
virtual Line Card 00, and will be listed together with
the events received on the physical Line Cards of the
receiver.
With this ability, the receiver can be used to upgrade
older systems, or to link multiple receivers through
the serial ports and act as one, big receiver from the
view of the central station computer. This option
could be useful, when the central station computer
has only limited number of serial ports, and more
receivers has to be used in the system.
The speed and data byte protocol of COM2 can be
set similarly as the COM1’s. The default setting is
9600 bps, 8 databits, no parity, 1 stopbit.
Serial Communication
When the CPM receives a message from a Line
Card, from COM2 or there is a CPM status event, it
records the event in the memory buffer then forwards
the event to COM1 and awaits acknowledge signal
from the computer. Normally a positive acknowledge
is received, and the receiver steps to the next
reportable event.
If no acknowledge or negative acknowledge signal is
received, the CPM will try to resend the event 3 more
times. If all attempts fail, the receiver generates a
“COM1 Error” event, and will keep it in the memory
buffer and repeatedly try to send the event until it
succeeds. The CPM Unit can store up to 4096 events
in its memory buffer if the connection to the central
station computer is broken.
If the receiver succeeds to send the event after a
communication failure, a “COM1 Restored” event will
be recorded. After the communication channel is
restored, the CPM will send all pending reportable
events from its memory buffer to the computer. This
method provides reliable and supervised
communication between the CPM and the central
station computer.
The COM1 port is also supervised with heart-beat
signals. The heart-beat signals are used to test the
communication channels between the receiver and
the central station computer when there is no
reportable event in the memory buffer. It works that
way, that the receiver sends so called heart-beat
signals to the computer in a programmed time and
requires acknowledge for that. If the acknowledge is
missing or negative, it assumes that the computer is
failed, and gives “COM1 Error” message.
If the automation software is not compatible with
heart-beat supervision, the heart-beat signals can
also be turned off (See CPM Options).
Serial Protocols
The receiver uses different serial communication
protocols for the connection to the automation
software on the central station computer. Which
protocol is used depends on which format has the
event that has to be forwarded to the computer. The
serial protocols used by the ENIGMA receiver are the
following

Basic Signal Protocol
The Basic Signal Protocol is the mostly used protocol
by the receiver. Receiver status events and most of
the events received by the Line Cards are forwarded
to the CPM using this protocol. The protocol format
