INTRODUCTION

The MLR2-E is a Multi-Line, Multi-Format Digital Receiver for

commercial fire and burglary. The basic unit consists of up

to 30 individual line cards (DRL2E) connected to a CPM2.

The MLR2-E can decode a variety of popular and widely

used communication formats. Refer to Appendix A, DRL2E

Communication Formats for a list of the available communication

protocols.

The MLR2-E’s real-time clock and calendar stamps all

information received with the time and date, and all information

may be printed and/or forwarded to a computer. To ensure

security, adjustment of the clock, calendar and other

programming is password-protected.

CPM2

The CPM2 Central Processing Module oversees operation

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

message screen, the CPM2 features one parallel printer,

and two COM Ports.

DRL2E

Each DRL2E Module can monitor two telephone lines. The

Line Card module is equipped with a 256-event nonvolatile

memory buffer to record events and corresponding telephone

numbers. Caller Source capability 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.

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 communications 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 communication link to the

computer through the RS-232 port is monitored by the

supervisory “heartbeat” test transmissions.

COMPATIBILITY

Central station automation software packages such as:

• M.A.S. • DICE • SIMSII • S.I.S. • GENESIS • MICROKEY

support the MLR2-E Sur-Gard interface. Compatibility with the

automation software in a system used at a central station is

intended to be handled under a separate UL 1981 software

and/or site certification evaluation.

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 programming slowly flashes

the OPTION LED when the “OPTION” output is activated.

Switched negative outputs are also provided for the

Acknowledge and Trouble LEDs.

VIRTUAL RECEIVER ARCHITECTURE

The most novel feature of the DRL2E is the 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 security

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.

NUMBER OF LINE CARDS SUPPORTED

The system will support a maximum of 15 line cards concurrently

connected.
