1 GENERAL INFORMATION
1.1 SYSTEM DESCRIPTION
The overall system is known as the SYSTEM 3505 PRISM LX Multiplex Alarm
Monitoring System. For proper operation of the DGM units you need to have a
SYSTEM 3505 PRISM LX with multiplex option. You also need to have sufficient
memory in your SYSTEM 3505 PRISM LX to provide at least one text screen per
zone. The zone priority level is entered via the user text message section. This
system can support up to 128-line drivers. Each line driver can be a style 3, 6 or 7.
Styles 3 & 6 can support up to 99 Data Gathering Modules
(DGM’s), based on total
distance, per loop. Style 7 can support any number of DGM panels since each DGM
panel repeats the signal. DGM panels can monitor a maximum of 64 EOL (End Of
Line) monitoring points and can activate up to 64 relay output points, by the use of a
“piggy-back” relay board or additional relay enclosure. The maximum number of
DGM’s supported by one SYSTEM 3505 PRISM LX is 500, and the maximum
number of zones for one system is 16,000.
The overall system is designed as a proprietary alarm monitoring system and is
suitable for monitoring fire and security alarms per NFPA 72. The system can also
be used for energy management and process controls.
1.2 DGM DESCRIPTION
DIGITIZE models DGM-32, DGM-32-RLY, DGM-32-RF and DGM-32-M32-RLY are
multiplex data gathering modules capable of monitoring 32 supervised input points.
(See Figures 1.1, 1.2, and 1.3.) Also supervised are “AC POWER”, “TAMPER”,
“GROUND” and “BATTERY” fault conditions. Each standard model is housed in a
painted steel enclosure with a hinged door, and is supplied with a step-down AC
transformer, tamper switch, cam lock, 32 character LCD display and keypad,
rechargeable battery pack rated for 60 hours of standby power and an integral
battery charger. The DGM -32-RLY and DGM-32-M-RLY provide additional
mounting space for relay modules, as well as power to energize the relays. The
DGM-32-M-RLY-RF and DGM32-RF are data gathering modules that communicates
via two-way radio.
The DGM can be ordered in eight-zone increments, initially, and then upgraded to
the full 32 zones. It is also possible to upgrade to a DGM-64 in the field, by adding
an additional 32 zone EOL card.
