1. Introduction
The ENIGMA XM88422 is a multi-line, multi-format
digital receiver for commercial fire and burglary
monitoring. The standard unit consists of a CPM
Central Processing Module, a DLCM Dual Line Card
Module and a PWR Power Module. With additional
Dual Line Card Modules, the receiver can be enabled
to monitor up to 30 telephone lines. The ENIGMA
XM88422 can receive and decode most of the
popular and commonly used communication formats.
See Appendix B. for details
The ENIGMA XM88422 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.
CPM Unit
The Central Processing Unit controls the operation of
the receiver. Along with its large graphical LCD
screen, the CPM Unit incorporates two serial and one
parallel interface for computer and printer interface.
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 4096-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 CPM Unit will retain the
incoming events in its buffer, and will automatically
forward them, when the connection restores.
The CPM Unit has a large graphical LCD display
which enables the CPM to implement unique, user
friendly features like changeable display font sizes,
and pull-down menus and dialog boxes for
programming.
Line Cards
Each Dual Line Card Module contains two
independent Line Cards and each Line Card can
monitor a telephone line. The Line Cards contain a
1600-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 screens and printer and/or forwarded to the
computer. The Line Card Module 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, with their individual
LCD displays and controls. Each Line Card will
continue receiving events and store them in its buffer.
The events will be forwarded to the CPM Unit after
the connection restores.
Power Module
The Power Module supplies the power for the other
modules in the receiver. It requires 16.5 VAC from a
115 or 230 VAC, 50/60 Hz, transformer. The Power
Module is equipped with automatic battery charger
and backup battery connections. In case of AC failure
the Power Module automatically switches to backup
battery power. The backup battery capacity can be
between 7 and 15 Ah. The Power Module supervises
the presence of the battery and the battery capacity
and the current status is reported to the CPM Unit.
