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.
The following assemblies make up a DGM-32/64:
LCD display and keyboard assembly Part # 400373-0003
Microcontroller board Part # 400464-0002
* 32 zone input board Part # 400601-#

DGM INSTALLATION AND MAINTENANCE MANUAL
2 700135-0000 Rev. O
Transformer assembly Part # 900546-0000
12 Volt 12 AH battery Part # 900414-0006
* Two 32 zone input boards are required for DGM-64.
One Multiplex Communication Card must be selected from the following (only one
may be used per DGM):
RS-422/485 Dual Line Interface card Part # 400405-0003
RS-232 Card Part # 400407-0003
Audio Modem Card Part # 400475-0002
Fiber Optic Card Part # 400506-0002
RF Radio Frequency Interface Assembly:
Radio Telemetry Module Part # 900708-#
RF Driver Board Part # 400605-0001
* RS-422/485 is considered the standard driver card for DGM-32-M-RLY units.
The Microcontroller board is a micro-processor-based controller board. All functions
of the DGM-32-M-RLY are controlled by a program that resides in an EPROM
program chip. This flexibility in the product allows the user to select such things as
output format, set DGM number, etc. The transmitter assembly provides all power
output regulation. The transformer assembly is used to step down the 120 VAC input
voltage to 16 VAC required for proper operation of the DGM-32-M-RLY. The sealed
lead acid battery supplied provides the required 12.6 VDC for battery backup. The
battery is a 12 Amp Hour battery and will operate the DGM-32-M-RLY for a
minimum of 60 hours during an AC failure. The LCD display and keyboard allows
the operator to view ALARM & TROUBLE information on a 32 character display as
local annunciation. The keypad provides access to field programmable functions for
the DGM-32-MRLY. NOTE: Battery backup time is shorter with radio (RF) option.
1.3 OPTIONS
1.3.1 32 ZONE EOL
The 32 ZONE EOL (P/N. 400601-#) is the 32-zone end-of-line (EOL) resistor
supervised expansion board for the DGM-32. The 32 ZONE EOL provides lightning
protection for each zone. This board is used to expand a DGM-32 to 64 zones.
1.3.2 RLY-8
The RLY-8, (P/N. 400375-0000), provides eight non-supervised Form C outputs. Up
to eight RLY-8 boards may be added to DGM-32-RLY and DGM-32-M-RLY panels.
1.3.3 COMMUNICATIONS STYLES
The DGM panels can communicate with the SYSTEM 3505 PRISM LX in several
different styles. The standard format is by wire using RS-422/485. When ordering a
DGM-32-M-RLY you will get the “Style 3/6” RS-422/485 communications interface.

2.3.3 MOUNTING INSTRUCTIONS
The cabinet supplied with the standard model DGM is designed for surface
mounting. The mounting area must be a smooth, clean surface on a permanent
partition. The cabinet must be securely fastened to the mounting surface using the
four mounting holes. For this, #10 or 1/4" screws are suggested. The mounting
location should be planned to allow full access to the top, bottom and sides for ease
of conduit entry. When mounted, panel indicators and labels should be plainly
visible, and the cabinet door must be able to swing to the full open position.
Following these guidelines will facilitate ease in installation, operation and
maintenance.
Clean out any dirt produced during installation and reverse the procedure for
disassembly to reinstall electronics back into the enclosure.
2.4 WIRING
2.4.1 CONDUIT CONNECTIONS
Connect all wiring conduit to the cabinet in accordance with applicable National
Electric Code, State and Local building code requirements. The cabinet is supplied
with pre-stressed 1/2" knock-outs. Please note that the lower shelf of the cabinet is
used primarily for standby battery placement. If the bottom shelf must be used for
conduit entry, make sure the wiring does not interfere with battery installation.
2.4.2 FIELD WIRING
Pull all power feeds and field wiring through the conduit and into the cabinet. Never
place power feeds and field wiring in the same conduit. All field wiring must be
tested for grounds, induced voltages, open and shorted circuits. All field wiring must
be free of these conditions prior to connecting them to peripheral devices or to the
DGM. Do not connect field wiring until the DGM has been fully tested. Tag all wiring
for later connection to the unit. Please refer to Section 3, SYSTEM INITIALIZATION.
Failure to comply with these guidelines may cause damage to the unit.
The zone inputs are designed to be connected to field wiring with a maximum
resistance of 750 Ohms. When a zone input is connected to field wiring longer than
20 feet, lightning protection must be provided. The 32 zone EOL interface provides
such protection. The panel must be properly grounded. Proper grounding is required
both for safety and proper operation of the lightning protection and ground fault
circuits.
2.5 MAIN BOARD
2.5.1 GENERAL
This is the main microcontroller board for the panel. It contains the firmware that
operates the panel.
