SECTION 1
GENERAL IN ORMATION
1.1 SYSTEM DESCRIPTION
The overall system is known as the SYSTEM 3000 ISOdressa le  Multiplex Alarm
Monitoring System. For proper operation of the DGM ISO-8L units you need to have a
SYSTEM 3000 with multiplex option. You also need to have sufficient memory in your
SYSTEM 3000 to provide at least one text screen per zone. The zone priority level is
entered via the user text message section. This system is capa le of supporting up to
eight loop drivers. Each loop driver can e a style 3 or 6. Styles 3 & 6 can support up to
99 ISO-6Z’s, ased on total distance, per loop. Each ISO-6Z can monitor up to six zones,
plus Tamper. The maximum num er of DGM ISO-8L’s supported y one SYSTEM
3000 is 500.
The overall system is designed as a propriety alarm monitoring system and is suita le for
monitoring fire and security alarms per NFPA 72. The system can also e used for
energy management and process controls.
1.2 DGM ISO-8L DESCRIPTION
The DIGITIZE model DGM ISO-8L, (Figure 1.1), is an ISOdressa le  multiplex data
gathering module, capa le of monitoring up to eight loops. Also supervised are “AC
POWER”, “TAMPER”, “LOOP GROUNDS” 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, rechargea le attery pack rated for 24 hours of stand y power and an
integral attery charger. The DGM ISO-8L-RF is a data-gathering module that
communicates via two-way radio.
The DGM ISO-8L can e ordered with one loop driver card, initially, and then upgraded
to the full eight loops. Each loop driver card is supplied with a separate lightning
protection oard. Both the loop driver card and lightning protection oard are plugged
into the ISOdressa le Connector Board. Each loop driver card can monitor up to 99 ISO-
6Z units (Figure 1.2). The ISO-6Z unit can monitor up to six zones.

The following assem lies are standard on every DGM ISO-8L:
LCD display and key oard assem ly Part # 400373-0000
Microcontroller oard Part # 400488-0000
ISO-Controller oard Part # 400489-0000
Transformer assem ly Part # 450440-0001
12 Volt 12 AH attery Part # 900414-0006
Power Supply/Charger Part # 400467-0001
At least one ISO Loop Driver Board must e selected from the following (a total of eight
oards may e used in any com ination):
Style 3 Loop Driver Part # 400490-0001
Style 6 Loop Driver Part # 400490-0002
One Lightning Protection Board is supplied with each ISO Loop Driver Board.
Lightning Protection Board Part # 400507-0001
One Multiplex Communication Card must e selected from the following (only one may
e used per DGM ISO-8L):
RS-422/485 Dual Line Interface card Part # 400383-0001 *
RS-232 card Part # 400383-0005
Fi er Optic card Part # 400506-0002
RF Radio Frequency Interface assem ly:
Radio Telemetry Module Part # 900708-0001
RF Driver Board part # 400455-0001
*RS-422/485 is considered the standard driver card for ISO-8L units.
The Microcontroller oard is a microprocessor ased controller oard. All functions of
the DGM ISO-8L are controlled y a program that resides in an EPROM program chip.
This flexi ility in the product allows the user to select such things as output format, set
ISO-unit num er, etc. The transmitter assem ly provides all power output regulation.
The transformer assem ly is used to step down the 120 VAC input voltage to 16 VAC
required for proper operation of the DGM ISO-8L. The sealed lead acid attery supplied
provides the required 12.6 VDC for attery ackup. The attery is a 12 Amp Hour
attery and will operate the DGM ISO-8L for a minimum of 24 hours during an AC
failure. The LCD display and key oard allows the operator to view ALARM &
TROUBLE information on a 32-character display as local annunciation. The keypad
provides access to field programma le functions for the DGM ISO-8L.

1.3 OPTIONS
1.3.1 COMMUNICATIONS STYLES
The DGM ISO-8L panels can communicate with the SYSTEM 3000 in several
different styles. The standard format is y wiring using RS-422/485. When
ordering a DGM ISO-8L you will get the “Style 3” RS-422/485 communications
interface. By adding the following suffixes to the ase num er, your DGM ISO-
8L will e shipped with the desired interface.
- RS232 indicates communications protocol is RS-232.
- R indicates communications is to e via two-way polling radio.
- iber indicates communications will e via fi er optic ca le.
Regardless of what style is selected, the SYSTEM 3000 must e equipped with
the proper interface to handle the selected communications protocol. A
DIGITIZE Multiplex system can mix and match any communications protocol
availa le.
1.3.2 COLOR
Each DGM ISO-8L is availa le in a choice of two colors:
Red is ordered as DGM ISO-8L-R
Brown is ordered as DGM ISO-8L-B

INSTALLATION
2.1 HANDLING
2.1.1 PRECAUTIONS
2.1.2 UNPACKING AND INSPECTION
Before opening, inspect the shipping container for unusual damage. Then,
carefully unpack the unit and inspect it for scratches, dents, and loose internal
components. If your inspection reveals any physical damage, retain the packing
material and contact the shipping carrier immediately. Each unit has een
thoroughly prior to shipment. When returning a damaged panel, retain the tie
wraps for the inner door hinge and latch. Failure to tie wrap the inner door during
shipping may result in additional damage. Note: Keep unit in shipping container
until ready to mount
2.2 CABINET MOUNTING
2.2.1 SITE PREPARATION
The installation area should e: well lit, clean, easily accessi le and free from
extremes of temperature and humidity. Please refer to Section 1.4.7,
TEMPATURE AND HUMIDITY for the maximum operating conditions.
2.2.2 DISASSEMBLY PROCEDURE
STEP 1: Retrieve the unit from its shipping container and place the ack of the
unit down on a flat surface.
STEP 2: Using a CAT-1 key, (two are supplied in an envelope marked “KEYS”)
open the hinge door.
STEP 3: Open the inner door and unplug any connectors and wire harnesses that
connect the equipment on the door to the equipment inside the ca inet. Wires and
ri on ca les should e connected on the ca inet side. When the inner door is in
the open position, lift it to remove it. Place equipment that has een removed in a
safe location.
CAUTION!
Do not touch circuitry during installation. Static discharge may
damage components.

Step 4: Remove the four mounting nuts that secure the ack plate to the
enclosure. Remove the ack plate from the enclosure.
2.2.3 MOUNTING INSTRUCTIONS
The ca inet supplied with the standard model DGM ISO-8L is designed for
surface mounting. The mounting area must e a smooth, clean surface on a
permanent partition. The ca inet must e securely fastened to the mounting
surface using the four mounting holes. For this, # 10 or ¼” screws are suggested.
The mounting location should e planned to allow full access to the top, ottom
and sides for ease of conduit entry. When mounted, panel indicators and la els
should e plainly visi le, and the ca inet door must e a le to swing to the full
open position. Follow these guidelines will facilitate ease in installation,
operation and maintenance.
Clean out any dirt produced during installation and reverse the procedure for
disassem ly to reinstall electronics ack into the enclosure.
2.3 WIRING
2.3.1 CONDUIT CONNECTIONS
Connect all wiring conduit to the ca inet in accordance with applica le National
Electric code, State and Local uilding code requirements. The ca inet is
supplied with pre-stressed ½” knockouts. Please note that the lower shelf of the
ca inet is used primarily for stand y attery placement. If the ottom shelf must
e used for conduit entry, make sure the wiring does not interfere with attery
installation.
2.3.2 ILED WIRING
Pull all power feeds and field wiring through the conduit and into the ca inet.
Never place power feeds and field wiring in the same conduit. All field wiring
must e tested for grounds, induced voltages, open and shorted circuits. All field
wiring must e free of these conditions prior to connecting them to peripheral
devices or to the DGM ISO-8L. Do not connect field wiring until the DGM ISO-
8L has een fully tested. Tag all wiring for later connection to the unit. Please
refer to Section 3, SYSTEM INITIALIZATION and to the inter-equipment wiring
diagrams, (Appendix A). Failure to comply with these guidelines may cause
damage to the unit.
