INTRODUCTION
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 a 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,
ALARMSOFT, APROPOS, BOLD, CSM SIMS, DICE, GENESIS,
MAS, MENTOR, MICRO KEY, MONITOR, SMS, SIMS and SIS
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.
SG-DRL2A
NEW SOFTWARE RELEASE VERSION 2.1i
NEW FEATURES
Modem Detection
Upon power up, each line card will detect whether the modem installed is Bell 103 or CCITT v.21, and then print the
result.
Delay Time Before Hang-up
The time between the last kiss-off and when the receiver hangs up, now follows the time programmed in the interval delay
between handshakes (option [48]).
Delay Time Between Pickup and First Handshake
The delay between the time that the receiver picks up the line and when the first handshake is sent out, can now be varied
from 0.2 - 2 seconds (EPROM programmable).
Scantronics 283 digits account code implementation
The MLR2-DG is a Multi-Line, Multi-Format Digital Receiver,
Listed U.L. and U.L.C. for commercial fire and burglary.
The basic unit consists of a CPM2 Central Processor Module
and a two 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 protocols.
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
The MLR2-DG requires 16VAC, 40VA from a 115V or 230
VAC 50/60 Hz transformer. When more than 6 lines (3 DRL2A)
are installed, a 16VAC, 75VA transformer is required. The
receiver is equipped with 12V rechargeable stand-by battery
connections and automatic battery charger.
