EN GMA DR-81000 Digital Receiver Version 2.00
1. Introduction
The ENIGMA II DR-81000 is a multi-line, multi-format
P / PSTN / Radio digital receiver for commercial fire
and burglary monitoring. The base unit contains a
CPM Central Processing Card with IP support, and
a PWR Power Card. With additional LC2 Line
Cards, the receiver can be enabled to monitor up to
8 telephone lines. Adding an optional RC2 Radio
Card to the system enables radio receiver
functionality. The EN GMA DR-81000 can receive
and decode most of the popular and commonly used
communication formats, for both P and PSTN
reception. See Appendix B. for details
The EN GMA DR-81000 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.
CPM2 Card
The Central Processing Unit (CPM2) controls the
operation of the receiver. The CPM Unit incorporates
two serial ports, a high-speed USB port, a 10-BaseT
Ethernet interface for P reception and one parallel
printer port. 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 2000-event non-volatile
memory buffer. The contents of the buffer may be
browsed on the LCD screen. f the printer or
computer is off-line, the CPM2 Card will store the
incoming events in its buffer, and will automatically
forward them, when the connection restores.
The CPM2 controls the large graphical LCD display
of the receiver, which enables it to implement unique,
user friendly features like changeable display font
sizes, full line card control, and easy-to-use manual
programming.
LC2 Line Cards
Each Line Card (LC2) can monitor a telephone line.
The Line Cards contain a 500-event event memory to
record events and caller information. Caller
dentification 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 screen and printer and/or forwarded to the
computer. The Line Card also verifies the
communication with the CPM Unit. n 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 - it will continue
receiving events and store them in its buffer. The
events will be forwarded to the CPM Unit after the
connection restores.
RC2 Radio Receiver Card
The Radio Receiver Card (RC2) acts as a special line
card in the system – it receives encoded messages
from radio transceivers (UHF, 440..450MHz). The
RC2 Card can handle up to 2 radio receivers, which
enables it to monitor 2 radio channels
simultaneously. The reception, decoding, storing and
forwarding of the messages work similar to the LC2
Line Cards. The Radio Card is also capable of stand-
alone operation in case the connection with the
CPM2 fails – it can store up to 500 messages in its
non-volatile buffer.
PWR2 Power Card
The Power Card supplies the power for the other
Cards in the receiver. t requires 16.5 VAC from a
115 or 230 VAC, 50/60 Hz, transformer. The Power
Card is equipped with automatic battery charger and
backup battery connections. n case of AC failure the
Power Card automatically switches to backup battery
power. The backup battery capacity can be between
7 and 15 Ah. The Power Card supervises the
presence of the battery and the battery capacity and
the current status is reported to the CPM Unit.
Compatibility
The EN GMA DR-81000 Digital Receiver is
compatible with the most commonly used automation
software packages. The receiver has been tested to
work with the following software:
−Alarm SyS
−S MS
−Microkey S S
−Cortex WinSC Security Commander
For other automation software, if not supported
directly, generally, selecting the Enigma XM88422 or
the Surgard MLR2 driver will provide compatible
support for the receiver.
