Section 1 - Introduction
The MLR2E is a multi-line, multi-format digital receiver for
commercial fire and burglary. The basic unit consists of up
to 15 individual line card modules (DRL2E) and 30 telco
lines connected to a CPM2. The MLR2E can decode a vari-
ety of popular and widely used communication formats.
Refer to Appendix A, DRL2E Communication Formats for a
list of the available communication protocols.
The MLR2E’s real-time clock and calendar stamps all infor-
mation received with the time and date, and all information
can be printed and/or forwarded to a computer. To ensure
security, adjustment of the clock, calendar and other pro-
gramming is password-protected.
1.1 CPM2
The CPM2 Central Processing Module oversees oper-
ation of the line cards. Along with its built-in keypad
and LCD message screen, the CPM2 features one par-
allel printer port, and two COM Ports.
1.2 DRL2E
Each DRL2E module can monitor two telephone lines.
The line card module is equipped with a 256-event
non-volatile memory buffer to record events and cor-
responding telephone numbers. Caller Source capabil-
ity is built-in and telephone numbers can be printed
out, sent to automation and stored in memory. Events
and information stored in memory can be printed at
any time. Each line card also features flash EPROM
uploads through the Debug port for software
upgrades or options programming.
1.3 Supervision
The standby battery voltage and connections are
supervised. The line cards are also continuously
supervised to ensure uninterrupted communication
with the CPM2. Any trouble conditions are reported
on the LCD screens and sent to the printer and the
computer.
The DRL2E line card module also verifies communica-
tions with the CPM2. In the event of a malfunction,
the operator will be advised with a visual indication
and the line cards will continue to function. Each line
card will continue to receive information.
The printer is supervised for loss of power, off-line,
paper out and other trouble conditions. The commu-
nication link to the computer through the RS-232 port
is monitored by the supervisory “heartbeat” test
transmissions.
1.3.1 Compatibility
Central station automation software packages such as
M.A.S., DICE, SIMSII, S.I.S., GENESIS and MICROKEY
support the MLR2E Sur-Gard interface. Compatibility
with the automation software in a system used at a
central station is intended to be handled under a sep-
arate UL 1981 software package and/or site certifica-
tion evaluation.
1.4 CPM2 Outputs/Inputs
The CPM2 features three switched-negative outputs.
One output labeled “OPTION” has a corresponding
LED on the CPM2 front panel; the factory default pro-
gramming slowly flashes the OPTION LED when the
“OPTION” output is activated. Switched negative out-
puts are also provided for the Acknowledge and Trou-
ble LEDs.

1.6 Virtual Receiver Architecture
The most novel feature of the DRL2E is its ability to
use the telephone company information delivered as
DNIS (Dialed Number Information Service) or Caller
ID. This allows the Sur-Gard Format Expert System to
handle on the fly each received call. With this feature,
dedicated line pool hardware is eliminated. Instead,
the DNIS or Caller ID information allows dynamic
options that set up virtual line pools to identify secu-
rity formats and extend account numbers.
Standard DNIS is supported up to 10 digits. Each
dialed number should be assigned to a virtual receiver.
Multiple Caller ID numbers can be assigned to a single
virtual receiver. Each dialed number would formerly
have been a line pool on conventional line cards.
1.7 Number of Line Cards Supported
The system will support a maximum of 15 line card
modules concurrently connected.
1.8 Approvals

Section 4 - DRL2E Digital Receiver Line Card
The DRL2E acts as an interface between the digital alarm
transmitter and the CPM2. Different communication for-
mats can be used to transmit the information.
The main functions of the line cards are to continuously
monitor the telephone line, receive calls from digital dialers
or control panels, and to report alarms to the CPM2. In
addition, each line is capable of functioning independently
when communication is lost between the line card and the
CPM2. Each line card can record 256 different alarm mes-
sages and 255 Caller-ID telephone numbers.
4.1 General information
The receiver is capable of processing signals from dig-
ital communicators in a variety of formats. The type of
signal (alarm, trouble, restore, cancel and so on) can
be printed.
4.2 DRL2E Features
• Operator selection of communication formats and
handshake priority
• 64 profiles per line, up to 30 lines.
• Flash Download for software upgrades.
• Records up to 256 messages.
• Records up to 256 Caller ID phone numbers. This
feature helps to locate and identify the source of
the device in communication and assists in trouble-
shooting.
• Multiple alarms are forwarded to the computer and
printer through the CPM2 with minimum delay
• The DRL2E monitors the telephone line connec-
tion, and line faults will result in reports to the
computer and the printer
• DRL2E automatically goes into standalone mode in
case of CPM2 failure
• “Watchdog” timer continually monitors receiver
operation
• “Cold boot” option allows receiver’s configuration
to be reset to factory default programming

5.3 Communications in Progress
5.3.1 Data Reception
During data reception, a message similar to this will
be displayed:
In Communication
1234 56
If valid Caller Identification information is received, a
message similar to this will be displayed:
TEL:[phone]
1234 56
The DRL2E decodes all information received and
stores the information in its event buffer. When a valid
signal is received, the DRL2E sends a kissoff signal
and transmits the decoded alarm signal to the com-
puter and then to the printer through the CPM2.
Options [1D] and [1E] can be adjusted to allow the
DRL2E to compensate for weak signals or noisy tele-
phone lines; refer to “DRL2E Programmable Features”
for information on programming these options.
The DRL2E will send each message it receives to the
printer for review by the system operator. Two mes-
sages may be sent to the printer to indicate reception
problems: “Invalid Report” and “Communication Fail”.
5.3.2 Invalid Report Message
When this problem is encountered, the following
information is transmitted to the printer and the com-
puter:
Printer: L01- 0000-INVALID REPORT TIME:DATE
Computer: 0RRL[#0000 | NYNRRL]
NOTE: The first RRL is subject to the line card
length option.The second RRL is the receiver and
line card number, both in HEX.
This output for account code “0000” indicates that
data has been received, but is not valid (for example,
there are unmatched rounds or the wrong parity). The
following is an example of faulty data received by the
DRL2E, and the printer output generated:
NOTE: There is only 1 invalid report at the end of a
call.
5.3.3 Communication Fail
When this problem is encountered, the following
information is transmitted to the printer and the com-
puter:
Printer: L01-0000-COMMUNICATION FAIL TIME:
DATE
Computer: 0RRL[#0000 | NYCRRL]
NOTE: The first RRL is subject to the line card
length option. The second RRLL is the receiver and
line card number, both in HEX.
This output indicates that a call was received, but no
data was detected. The call may have been a wrong
number, or the calling control panel was unable to
connect with the receiver’s handshake.
5.3.4 Caller ID
If an Invalid Report or Communication Fail occurs,
and Caller ID is enabled, the printer messages will be
similar to the following:
Fault Data: “??????10 5551212”
Fault Call: “??????40 5551212”
Note that “?” represents the missing data; “5551212”
represents the originating telephone number.
5.3.5 Stopping Data Reception Manually
To cancel communications between the DRL2E line
card and the calling control panel, press the [CANCEL]
button. Pressing the [CANCEL] button will hang up the
line. This feature can be used to hang up on a control
panel that is repeatedly sending alarms.

Section 6 - Profiles
6.1 Introduction
The DRL2E 'virtual receiver' will load unique 'profiles' in
order to effectively communicate with control panels.
A profile is a set of pre-programmed line card options
unique for a particular DNIS number. The 'DNIS' will
point to a particular profile, which will then be loaded
into the line card before the first handshake is sent. It
is essential that the correct option be programmed for
a profile in order to correctly communicate with the
control panel. Each 'virtual receiver' can have a maxi-
mum of 64 profiles. To change the options for a par-
ticular profile, the MLR2E Console software is
provided. This software will allow the user/operator to
edit the profiles.
NOTE: DNIS (Dialled Number Identification Ser-
vice). This number represents the dialled number,
or the number being called. Caller ID: This number
identifies the source of a call. Contact your pro-
vider to determine which service is available.
DNIS or Caller ID can be used for profile selection.
Line Cards Identification Number Handling:
Figure 8, Call Processing Flowchart
Each profile is made up of Static Options and Dynamic
Options. The static options are the same for all pro-
files, but the dynamic options can be programmed
specifically per hunt groups, panel type, etc.
By receiving the DNIS or Caller ID, the appropriate
profile can be selected through a look-up table
"stored" on the line card.
Profile 0 is the default. When no Caller ID or DNIS is
received, or when the received number does not point
to a profile, the default will be used.
Profiles are used to reduce on-line time, and for spe-
cific customers or panel/format types, one can have a
profile with certain handshakes sent first. Also, some
formats require certain options, and this can be pre-
defined as well.
Profiles allow for a more customized system. Rather
than having a line card (or a receiver itself) devoted to
certain customers, the MLR2E can "handle" any format
at any time through the use of profiles. Each line card
holds its own look-up table that can be shared
through line pools, or shared within the entire receiver.
Two types of tables are available, but only one type can
be chosen. The first type, which consists of 10 000
entries, is used strictly with DNIS of up to 5-digits.
Table type 1:
DNIS receivedProfile # to be used
The second type is used if Caller ID is received, and
can consist of up to 10,000 entries, with up to 10 dig-
its.

Table type 2:
The receiver will check through the Caller ID section if a
Caller ID number is received. If the Caller ID is received but
the Caller ID was not found, it will check in the virtual
receiver number and line number located in the dynamic
options or profiles, and use profile 0.
On a standard receiver, the Automation output would look
similar to the following:
The duplication of accounts is not possible, as long as they
are dialling different numbers.
The output will become:
Where RR is the value programmed in Option 75 and L is
the value programmed in Option 74.
6.2 DRL2E Programming Commands
There are 5 main programming commands available
on the DRL2E line card module:
• F7 Options Programming
•FA BufferOutput
• FE Line Card Buffer Maintenance
Some programming commands feature options that
provide a variety of different functions; each com-
mand is fully explained in the following sections of this
manual.

6.2.1 F7 Line Card options Programming
Line Card-F7-Option-Code
The F7 Options Programming command is used to
change various operating parameters for the line card:
reporting codes, the line card number, buzzer opera-
tion and other features. Functions can also be changed
using the F7 command.
Refer to the example illustrated in 'Entering Com-
mands' in the 'DRL2E Programming Commands' sec-
tion of this manual.
Refer to the DRL2E Reference Sheets in the back of
this manual; be sure to record any programming
changes on these sheets.
NOTE: Options are programmed with 2 hexadecimal.
6.3 Static Options: [00] - [2F]
Option [00]: Reserved
Option [01]: Line Card Number - Default [00]
The line card Number provides a virtual identification
code for each DRL2E module. Hexadecimal numbers
'01' to 'FE' can be programmed in Option [01] to iden-
tify line cards.
Option [02]: Line Card Number Length - Default [0E]
This option is used to determine how many digits from
the line card number will be sent to the output. You
also have the option of displaying the number in hex or
decimal. Program Option 02 with one of the following:
01 Send only one Hex digit to the printer or computer
output (if you have a 2-digit line card number only
the last digit will be sent to the output)
02 Send 2 Hex digit line card number to the output
03 Send 3 Hex digit line card number to the output
(leading Zeros will be inserted prior to the line card
number)
0A Send 3-digit line card number as entered (no con-
version).
0D Send 3-digit line card number in decimal (conver-
sion from decimal to hex decimal
0E Send a 1-character line number 1-9, A-Z
Option [03]: Internal messages RS-232 - Default [01]
When this option is programmed as ‘00’, the DRL2E will
output its internal messages in the following format:
SRRL[#AAAA|Nxxyy]
If it is programmed as ’01’ internal messages will be
output as
0RRL[#AAAA|Nxxyy]
Where S, 0 (zero) = Protocol number
RR = Receiver number
L = Line number
AAAA = Account code, always 0000
Nxxyy = SIA event
Option [04]: 2-Way Audio Activation Time - Default
[00]*
Option [04] determines how long, in 10-second incre-
ments, the 2-way audio function will be active once it
is initiated. At the end of this time, the line card will
hang up the line. Program a value from "01" to "FF" for
10 seconds to 2550 seconds. Three (3) minutes is the
recommended length of time for the 2-way audio acti-
vation time. To disable the 2-way audio feature, pro-
gram Option [04] as "00".
NOTES: Enabling 2-way audio will affect NFPA 72
system loading requirements. Refer to Par. 4-5.3.2.2.2
of NFPA 72 for details.
If the alarm panel sends a listen-in code activation
request and audio is enabled for this format (Option
[7F]), the receiver will remain in two-way voice for a
period of 60 seconds even if the activation time is
not programmed.
* Use only with Model SG-MLR2E CE (not UL
listed).
Option [05]: Pre-H.S. Duration - Default [0A]
When the line card seizes the line, it will wait the time
programmed at Option [05]; then send the first hand-
shake. The value programmed (hex) at this location will
be multiplied by 100 ms. [e.g., 100 ms., 200 ms.] The
default is 0A, for 1000ms (100ms x default value).
The minimum time is 1 second. If the option is pro-
grammed with any value lower than 0A, the line card
will use a 1 second delay.
Options [06] to [0C]: Reserved
Option [0D]: Ring Select - Default [00]
Enables or disables the double ring detection. If pro-
grammed as 00, the line card will detect single ring. If
programmed as 01, the line card will detect the double
ring.
Option [0E-10]: Reserved
Option [11]: Hook-flash Enable/Disable - Default
[00]
Enables or disables ability to hookflash the phone line
and determines its duration in increments of 10 ms.
If programmed as 00, the option is disabled. If set to
anything else, you multiply the decimal equivalent of
the hex value by 10 ms and that is the duration. For
example, if hookflash time of 500 ms is wanted, pro-
gram Option 2A to 32 Hex.
Option [12]: Caller Source ID Option - Default [00]
Option [12] allows the line card to receive Caller Identi-
fication data or DNIS that is transmitted after the first
ring on the telephone line. The appropriate service must
be available and requested from the Telephone Com-
pany for this feature to be operational.

To use Option [14], Option [12] must be programmed
as "01" for Caller ID.
Options [15] - [16]: Reserved
Option [17]: DMP User Length - Default [00]
Option 17 is for the variable length zone and user
numbers. The first digit in the option represents the
user number and the second digit represents the zone
number. For example, if Option 17 is set for 24 than
the receiver will output a 2-digit user number and a 4-
digit zone number. The default value is 00 for 2-digit
zone and 2-digit user number.
Option [18]: Sur-Gard DTMF 4/3 Format Output -
Default [00]
Each nibbles of this option controls how the 4/3 format
computer output string is formatted. The first nibble
allows for the user and group codes for openings and
closings to be combined. When programmed as “1x”,
group arming/disarming signals will be combined with
the user code into one signal which will be sent to the
computer.

If a user code is not received after the group opening/
closing, the message “1234 C1 FF” will be sent; “FF”
indicates that a user code was not received.
The second nibble of this option controls the user/zone
number conversion. The Sur-Gard 4/3 DTMF format is
made up of a 4-digit account code, a 1-digit event
code, and a 2-digit hexadecimal zone code or user
number. However, some central station software pack-
ages use a common event code and require decimal
user codes. This option allows the user codes to be
converted from hexadecimal to decimal to meet the
needs of the central station software. Program with
one of the following:
x0
x1
Send the last two digits as user codes without
conversion
Convert the last 2-digit user codes to decimal
as shown here:
User Code receive
00 to 99
B0 to B9
C0 to C9
D0 to D9
E0 to E9
F0 to F9
User Code after
conversion
00 to 99
100 to 109
110 to 119
120 to 129
130 to 139
140 to 149
x2
x3
Example, if 1234 4B1 is received, 1234 C 101
will be sent to the computer.
Send the last 3 digits as the zone codes with
the 5th digit still used as the event code
Example, if 1234 161 is received, 1234 A 161
will be sent to the computer.
When individual event codes are used, if 1234
401 is received, 1234 C 01 will be transmitted
to the computer. When common event codes
are used, if 1234 401 is received, 1234 Z 401
will be transmitted to the computer, where Z is
the common event code.
Send the last 3 digits as the zone codes and
convert the user codes only to decimal
NOTE: When the first nibble of the option is set to 1
the 3-digit user codes will be combined with the
group number as follows:
Code received
1234B01
12344B1
Code sent to computer
No transmission
1234 C1 101
Option [19]: Fault Call Counter - Default [00]
Option 19 is used for limiting the number of Fault Call
messages that are sent to the printer and computer.
The default setting will send a Fault Call alarm for every
10 Fault Calls. To have every Fault Call sent to the com-
puter and printer set Option 19 to 01.
Option [1A]: DNIS Input Sensitivity - Default [00]
NOTE: Do not change this option unless instructed
to do so by DSC Technical Support.
Option [1B]: Reserved

6.4 Dynamic Options: [30] - [FF]
Option [1C]: Busy Out - Default [00]
This option allows the line card to seize the phone line
in case of checksum error after download or when its
internal buffer is full after loss of communication with
the CPM. Program Option [1C] with one of the follow-
ing:
00
01
04
The line is seized if any of the conditions men-
tioned above occurs.
The line is NOT seized if any of the conditions
mentioned above occurs.
The line will be seized immediately
if the automation computer is absent.
NOTE: If the option is programmed to 01, the line
card will NOT buffer any new alarms once the inter-
nal buffer is full. Setting Option [1C] to 01 is NOT
RECOMMENDED.
Option [1D]: Input Sensitivity - Default [3F]
Option [1E]: Output Levels - Default [60]
Option [1F]: Debug Output - Default [00]
Set to 01 to enable. The debug mode should only be
used when required and disabled after use.
Option [20]: Reserved
Options [21] - [26]: Internal Use Only
Option [27]: Caller Source Process - Default [05]
This option determines how many digits of Caller ID or
DNIS the receiver will process.
0x - x is number of digits of DNIS or Caller ID to be
processed (range from 1 to A hex for Caller ID; range
from 1 to 05 for DNIS)
Options [28] - [29]: Reserved
Option [2A]: Hook-flash Delay - Default [00]
Time delay before hang-up option. Option value x
100ms to a maximum of 9.5 seconds.
Options [2B] - [2F]: Reserved
Options [30] - [3F]: 3/1 - 4/1 Digit 0-F
The DRL2E uses a unique Sur-Gard communication
format to transmit data through the CPM2 to the cen-
tral station computer. Event codes corresponding to
alarm codes in 10 to 40 Baud formats and DTMF 4/1
to 4/3 formats are used in this unique format to
enable the computer software to determine alarm
types.
The DRL2E will use the last digit of data received in
3/1 and 4/1 formats to determine the computer
event code. The event code will then be transmitted
to the central station computer. Refer to the DRL2E
Decoding Library for the complete set of event codes
used by the DRL2E. In Sections [30] through [3F],
program ASCII codes according to the Decoding
Library.
Do NOT use values other than 20-7F (ASCII).

Options [40] - [4F]: 3/2 - 4/2 Digit 0-F
The DRL2E will use the first digit following the
account code in 4/2, 3/1 extended or 3/2 formats to
determine the computer event code. The event code
will then be transmitted to the central station com-
puter. Refer to the DRL2E Decoding Library for the
complete set of event codes used by the DRL2E.
In Sections [40] through [4F], program ASCII codes
according to the Decoding Library. Do NOT use val-
ues other than 20-7F (ASCII).
