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.
