Canadian maintenance facility designated by the supplier. Any

repairs or alterations made by the user to this equipment, or

equipment malfunctions, may give the telecommunications company

cause to request the user to disconnect the equipment.

User should ensure for their own protection that the electrical ground

connections of the power utility, telephone lines and internal metallic

water pipe system, if present, are connected together. This precaution

may be particularly important in rural areas.

Caution: Users should not attempt to make such connections

themselves, but should contact the appropriate electric inspection

authority, or electrician, as appropriate.

NOTICE: The Load Number assigned to each terminal device denotes

the percentage of the total load to be connected to a telephone

loop which is used by teh device, to prevent overloading. The

termination on an interface may consist of any combination of

devices subject only to the requirement that the total of the Load

Numbers of all the devices does not exceed 100.

fonctionnement.

Pour sa propre protection, l’utilisateur doit s’assurer que tous les

fils de mise à la terre de la source d’énergie électrique, les lignes

téléphoniques et les canalisations d’eau métalliques, s’il y en a,

sont raccordés ensemble. Cette précaution est particulièrement

importante dans les régions rurales.

AVERTISSEMENT: L’utilisateur ne doit pas tenter de faire ces

raccordements lui-même; il doit avoir recours à un service d’inspection

des installations électriques, ou à un électricien, selon le cas.

L’indice de charge (IC) assigné à chaque dispositif terminal indique,

pour éviter toute surcharge, le pourcentage de la charge totale qui

peut être reccordée à un circuit té;éphonique bouclé utilisé par ce

dispositif. La terminaison deu circuit bouclé peut être constituée de

n’importe quelle combinaison de dispositifs, pourvu que la somme des

indices de charge de l’ensemble des dispositifs ne dépasse pas 100.

L’indice de charge de ce produit est 40.

Incidence of Harm

Should terminal equipment or protective circuitry cause harm to the telephone

network, the telephone company shall, where practicable, notify the customer

that temporary disconnection of service may be required; however, where

prior notice is not practicable, the telephone company may temporarily

discontinue service if such action is deemed reasonable in the circumstances.

In the case of such temporary discontinuance, the telephone company

shall promptly notify the customer and will be given the opportunity to

correct the situation.

Changes in Telephone Company Equipment or Facilities

The telephone company may make changes in its communications facilities,

equipment, operations or procedures, where such actions are reasonably

required and proper in its business. Should any such changes render the

customer’s terminal equipment incompatible with the telephone company

facilities, the customer shall be given adequate notice to effect the

modifications to maintain uninterrupted service.

General

This equipment should not be used on coin telephone lines. Connection

to party line service is subject to state tariffs.

Ringer Equivalence Number (REN)

The REN is useful to determine the quantity of devices that you may

connect to your telephone line and still have all of those devices ring

when your telephone number is called. In most, but not all areas, the sum

of the REN’s of all devices connected to one line should not exceed five

(5). To be certain of the number of devices that you may connect to your

line, you may want to contact your local telephone company.

Equipment Maintenance Facility

If you experience trouble with this telephone equipment, please contact

the facility indicated below for information on obtaining service or repairs.

The telephone company may ask you disconnect this equipment from the

network until the problem has been corrected or until you are sure that

the equipment is not malfunctioning.

INTRODUCTION

rechargeable stand-by battery connections and an automatic

battery charger.

The stand-by 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 may be

sent to the printer and the computer.

The DRL2A Line Card Module also verifies communications

with the CPM2. In the event of a malfunction, the operator

will be advised with an audible indication and the Line

Cards will continue to function with their individual LCD

displays and controls. Each line card will continue to receive

information, and the operator may review the event buffer

on each line card.

The printer is supervised for loss of power, off-line, paper

out and other trouble conditions. The communication link to

the computer through the RS232 port can be monitored by

the supervisory “heartbeat” test transmissions.

Compatibility

The DRL2A has one programmable output which in factory

default is used to indicate that faulty data has been received.

It can also be used for the video, audio and other applications.

Central station automation software packages such as:

• ABM • DICE • MICRO KEY • SIMS

• ALARMSOFT • GENESIS • SAMM • SIS

• APROPOS • MAS • SMS • SIMS CSM

and support the Sur-Gard interface. The receiver also provides

a basic communication protocol similar to the RADIONICS

6500 interface for other software packages that have yet to

be updated to include the Sur-Gard interface.

CPM2 Outputs

The CPM2 features three switched-negative outputs. One

output labelled “OPTION” has a corresponding LED on the

CPM2 front panel; the factory default programming slowly

flashes the OPTION LED when the “OPTION” output is

activated. Switched negative outputs are also provided for

the Acknowledge and Trouble LEDs.

The MLR2-DG is a Multi-Line, Multi-Format Digital Receiver,

(U.L. and U.L.C. listed) for commercial fire and burglary.

The basic unit consists of a CPM2 Central Processor Module

and a DRL2A Digital Receiver Line Card Module. Additional

DRL2A Line Cards may be added to enable the CPM2 to

monitor up to 14 telephone lines. The MLR2-DG includes

many features, all designed to make the receiver more

powerful and easier to use. The MLR2-DG can decode a

variety of popular and widely used communication formats.

Refer to Appendix D, DRL2A Communication Formats for a

list of the available communication protocol.

The MLR2-DG’s real-time clock and calendar “stamps” all

information received with the time and date, and all information

is displayed on the receiver’s LCD screens and may be

printed or forwarded to a computer. To ensure security,

adjustment of the clock, calendar and other programming

is protected by password codes.

CPM2

The CPM2 Central Processing Module oversees operation

of the receiver. Along with its built-in keypad and LCD

message screen, the CPM2 features both a printer and

computer interface.

The CPM2 features a 128-event nonvolatile memory buffer.

The buffer may be examined on the LCD screen or printed.

If the printer or computer is off-line, the CPM2 will retain

events in the buffer and will automatically send the events

to the computer or printer when communications are restored.

DRL2A

Each DRL2A Line Card Module can monitor two telephone

lines. The Line Card module is equipped with a 256-event

nonvolatile memory to record events and corresponding

telephone numbers. Caller Identification (Call Display)

capability is built-in and telephone numbers can be displayed,

printed out, and stored in memory. Events and information

stored in memory may be printed at any time.

Power and Supervision

Bench Testing

Becoming familiar with the connections and setup of the

unit on the work bench will make final installation more

straightforward.

The following items are required:

• 16VAC transformer

• 2 telephone lines

• One or more dialers or digital dialer control panels

Direct connection testing without the use of telephone lines

is possible by using the ring simulator switch input

connections on the back of the receiver

Dialers and control panels using an optocoupler phone line

interface will require a connection method providing a DC

current for direct connection testing.

application the CPM2 must be version 2.10 or greater.

Telephone Line Connections

• With 6-pin modular cables, connect each line module

output to its corresponding telephone line.

Grounding

• For maximum resistant to static and electrical noise, the

19" rack frame should be connected to earth ground through

the AC utility box.

Power Supply

• Ensure that all electrical connections are made correctly.

After verifying all connections, connect the RED and BLACK

leads to a 12VDC sealed rechargeable battery. Be sure

to observe polarity when connecting the battery. When

the battery is connected, test the system under battery

power only.

• If a separate DC input is used to power the LCD

backlighting during AC power failures, connect it to the

BLGT terminal. It must be a listed Fire-Protective Signalling

System power supply rated 12VDC. Connect the positive

lead from the DC supply to the BLGT terminal; connect

the negative lead from the DC supply to the GND terminal.

CAUTION: Connecting a positive (+) terminal to a

negative (-) terminal may cause a fire and possibly

serious personal harm.

Removing and Installing System

Components

Note that the receiver does not have to be powered down

when components are removed or installed.

To Remove the CPM2 Module

The CPM2 charges the battery and provides low battery

voltage disconnect; removing the CPM2 module will

disconnect the battery and shut down the entire system if

AC power is not available. If the CPM2 must be removed

during an AC power failure, first connect a temporary battery

(protected with a 5A fuse and reasonably charged) to the

+BATT and GND terminals of the DML2A before removing

the CPM2.

Remove the 4 retaining screws on the front panel of the

module. Slowly pull the module out of the metal cabinet.

After the CPM2 is replaced, remove the temporary battery

so that the CPM2 can properly maintain the main battery.

To Remove a Line Card Module

Remove the 4 retaining screws from the front panel of the

module. Slowly pull the module out of the metal cabinet.

To Install a Line Card Module

Adding a Line Card Module to the MLR2-DG requires the

addition of an MLRX Expansion Card Cage. Each MLRX

can hold two DRL2A modules. The MLRX is shipped with

power and communications bus cables.

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.

Caller ID

If a Fault Data or Fault call 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.

4.2 Stopping Data Reception Manually

To cancel communications between the DRL2A Line Card

and the calling control panel, press the [CANCEL] button.

Pressing the [CANCEL] button will hang up the line. This

feature may be used to hang up on a control panel that is

repeatedly sending alarms.

4.3 2-Way Audio Mode SG-MLR2-DG Receiver

Connections

The DRL2A features two telephone line outputs. The

connections are labelled HNDSET1 for the Left Line Card,

HNDSET2 for the Right Line Card. These terminals allow a

touch-tone telephone to be connected to the DRL2A for

voice communication over the same telephone line after

digital data has been received. This feature is especially

useful for medical signalling installations and vocal alarm

verifications.

IMPORTANT NOTE: If a regular touch-tone telephone is

used for 2-Way audio communication, the phone must be

left in the

off-hook

position. If the phone is not kept in the

off-hook position, the DRL2A will switch to an open line,

causing the line to be dropped (hang up).

If used with a PBX system, 2-Way audio communication

needs bridging resistors. Measure the handset phone

impedance and use a resistor of the same value. A typical

value is 220Ω/1 Watt.

If the impedance is incorrect, the handset terminal switchover

will behave as if switching to an on-hook phone, and the

line will be dropped.

Audio Communication Methods

Two methods are available for using the 2-Way Audio Mode:

Alarm type code Method

After the digital alarm data has been received and the

receiver has transmitted the last kissoff, the control panel

will transmit a constant tone of the data transmission

frequency for 500 ms. This signal will activate the 2-Way

Audio Mode.

The receiver compares the alarm type codes in 3/1, 4/1, 4/

2, 4/3, 10-40 BD or DTMF touch-tone formats to the value

programmed in Option [4C]. This is done to determine if

the 2-Way Audio Mode should be activated. This feature is

designed for use with medical signalling systems in areas

where privacy regulations apply.

This method of activation is recommended as it can

distinguish between different types of alarms from the same

panel, and activate the 2-Way Audio Mode only when

needed. Note that Options [49] and [4C] must be

programmed to use this method.

Reserved Account Code Range Method

The first digit of the Account Code is used to activate 2-

Way Audio Mode.

This method is used by some alarm panels and medical

signalling systems. The central station manager can group

these panels into a range of account codes in order to

switch on the 2-Way Audio Mode. The transmission of an

Account Code from any of these panels will trigger the

DRL2A’s 2-Way Audio Mode. Note that Options [49], [4A]

or [4B] must be programmed to use this method.

A combination of the two methods may also be used,

please refer to p.25.

Example:

Reserve a block of account codes, such as

800-9FF (for 3-digit formats) or 7000 - 8FFF ( for 4-digit

formats) for panels which can communicate in 2-Way Audio.

Audio Mode Operation

When in Audio Mode, the “Audio” light will be ON and this

message will be displayed:

-L01 Digital Rec-L01 Digital Rec

-L01 Digital Rec

TWO WAY AUDIO ONTWO WAY AUDIO ON

TWO WAY AUDIO ON

The DRL2A buzzer can be used to indicate Audio Mode

operation by programming Option [3E] MUTE BUZZER as

“02”. To silence the buzzer, press the [ACK] button.

Select Option [4D] to have a message indicating Audio

Mode operation sent to the printer and the computer.

For example, use the character “P” (for “phone”) to represent

Audio Mode operation. Program Option [4D] as “50” (the

ASCII code for “P” is 50). When Audio Mode operation has

begun, the following messages will be sent to the printer

and computer:

Printer: “L01-0000-P01 AudioLine1”

Computer: “0000 P 01”

• “L01” indicates Line Card 01

• “0000” used as the account code for internal signals

• “P” is the character programmed in Option [4D]; “01”

again is the Line Card number

2-Way Audio Mode operation may be manually cancelled

by pressing the [CANCEL] button. If not manually cancelled,

Audio Mode operation will automatically be cancelled when

the time programmed in Option [49] expires.

The Audio Mode may also be cancelled remotely through

the Ring Simulation input on the back of the receiver. Future

central station audio management equipment will be able

to use this input to hang up the line and put the receiver

in Stand-By Mode when the operator’s telephone is hung

up.

To disable the 2-Way Audio Mode feature, program Option

[49] as “00”.

An output is also available on the SG-DML2A module (TXPG1

and TXPG2) which may be used to indicate activation of

Audio Mode operation or to indicate which telephone line

should be picked up for audio operation.

For more details, please refer to the programmable options

section.

DRL2A SOFTWARE UPGRADE

PROCEDURE

To upgrade the DRL2A, you need to remove and replace

the old EPROM Chip located inside the DRL2A. The new

EPROM Chip contains the new program version for the line

card. All these instructions can be done with the receiver

powered up since all the modules are hot swappable.

Note: It is very important to print out the existing line card

configuration before doing the version update. To access

this command you have to press the “C” key on the keypad

of the receiver, then enter the password; default is “CAFE.”

The ## is the line card number. For multiple line cards wait

until one is done before giving the command to start another

print out.

Lcard:## Comd:FA

OP:04 Cd:04 Sc:

Follow the procedure describe below to perform the Version

Upgrade.

1Remove the DRL2A from the card

cage.

With a small screwdriver unscrew the four slot screws in

the front faceplate of the DRL2A. These screws do not

come all the way off. Therefore when they are about ¼

inch, 1cm, out from the faceplate they should not be holding

anymore. Gently removed the DRL2A from the card cage

by pulling on the handle located at the bottom of the line

card. If it does not easily remove make sure all the screws

are loose. (shown in fig.1)

2Remove the top plate of the

DRL2A to get access to the

inside of the line.

There are two screws at the front of the unit they are to

hold the LCD screen. It is important not to remove these

screws. You have to remove the four screws on top of the

plate. Some line cards models have two plastic screws at

the back of the plate

that need to be

removed. There is

also a ground wire

attached to the back

of the plate. Loosen

the screw that holds

the ground wire ¼

turn just to remove

the wire from the

plate(Screws

indicated with arrows

in Fig.2).

Remove the plate from the line card. The plate is still attached

to the line card through a flat ribbon wire and power wires.

Do not removed them, they hold the LCD screen data bus

and the power for the LCD screen.

3Changing the Software

Inside the line card there are 2 EPROM chips, one on the

left side for the top line card, and one on the right side for

the bottom line card.

Note: It is very important that before removing the old chip

to take note of the position the notch of the old chip. Then

put the new chip’s notch facing the same direction as the

old one, as instructed on the label inside the DRL2A. Some

sockets are bigger then the chip. If this is the case, leave

the extra pins at the notch end as shown in the fig 3.

After finding the EPROM chips on both sides of the line

card and taking note of their orientation, very carefully proceed

to remove the chips from their sockets (do that with a small

flat screwdriver or chip puller, for example). Put the new

EPROM chips the same way the old ones were, and make

sure they are inside the socket all the way.

4Reassemble

Put the top plate back on top of the DRL2A and secure it

with all the screws that you previously removed. If you did

remove the ground wire from the plate before, remember to

re-secure it before you close the top plate of the DRL2A.

5Cold Boot Activation

Turn the Program Enable (Prog. En.) Switch ON. Use a

small screwdriver to turn the switch ON position by turning

it clockwise a quarter turn. The Program Enable switch is

located on the left side of the DRL2A for the top line card

and resembles a recessed screw. (Shown in fig.4). The

Program Enable switch for the bottom line card is located

on the right side of the DRL2A. Both sides can be done at

the same time.

After the line card number has been entered, press and

hold the [Ack] and [Cancel/Select] button at the same time,

until this message is displayed:

TURN OFF SWITCHTURN OFF SWITCH

TURN OFF SWITCH

7 Turn Off Switch

The DRL2A will remain inoperative until the “Program

Enable” switch is turned OFF. To turn the switch OFF,

pull the DRL2A out of the card cage. Use again the

small screwdriver to turn the “Program Enable” switch

OFF by turning it counter-clockwise as shown on fig.4.

8 Re Install

Reinstall the DRL2A in the card cage by pushing it in all

the way in. If the message COLD BOOT re-appears on

the screen just slide the unit out again and make sure

the “Program Enable” switch is all the way to the off

position. Now you can secure the faceplate screws of

the DRL2A.

9 Ready

The DRL2A is now ready for operation under the factory

default configuration. You should now compare the default

settings and your back up setting to see if any location(s)

need to be programmed. The easiest way is to print the

default configuration on one of these DRL2A and compare

them. All the instructions on how to program the line

card can be found in the manual. However, if you have

any questions or difficulties please feel free to contact

the Sur-Gard Technical Support Department.
