1. Introduction
The ENIGMA II DR-81000 is a multi-line, multi-format
digital receiver for commercial fire and burglary
monitoring. The standard unit consists of a CPM
Central Processing Card, two LC Line Cards and a
PWR Power Card. With additional Line Cards, the
receiver can be enabled to monitor up to 8 telephone
lines. The ENIGMA II DR-81000 can receive and
decode most of the popular and commonly used
communication formats. See Appendix B. for details
The ENIGMA II 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, and an
Ethernet interface for computer connection 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. If 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
Identification 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. In 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 (option)
The Radio Receiver Card (RC2) acts as a special line
card in the system – it receives encoded messages
from an UHF radio (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. It 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. In 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 ENIGMA II 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
−SIMS II
−Microkey SIS
For other automation software, generally, it can be
used with selecting the Enigma XM88422 or the
Surgard MLR2 interface.
