Confidentiality Notice
This manual is provided solely as an operation, installation, and maintenance guide and contains sensitive
business and technical information that is confidential and proprietary to GAI-Tronics. GAI-Tronics retains
all intellectual property and other rights in or to the information contained herein, and such information may

General Information
The Model 703-004 Indoor Emergency Party Line Amplifier Enclosure is designed to be a component in a
GAI-Tronics SmartSeries system. It is a multi-party, 115 V amplifier enclosure that mates with a Model
701-80x or 701-90x Series Handset/Speaker Amplifier to form a SmartSeries station.
When connected to a SmartSeries system, the station is equipped to report the following information when
the handset is taken off-hook:
• Zone number
• Station address
• Party line (1 or 2)
All station reports are received by the Master Control Unit and annunciated on an access panel located in
the SmartSeries® control cabinet.
NOTES:
1. The Model 703-004 Enclosure can also mate with a standard 701 or 751 Series Amplifier; however,
the reporting feature is not operable with this combination.
2. EPL functionality is only possible if your system’s software is properly configured. Your system must
also have the address of the station intended to mate with the enclosure enabled. Should you have
questions regarding your system, please contact your nearest GAI-Tronics Service Center.

Installation
CAUTION
Do not install this equipment in hazardous areas or areas other than those
indicated on the approval listing in the Specification section of this manual. Such installation may
cause a safety hazard and consequent injury or property damage.
When installing an add-on station, consult the system layout diagrams at the end of this manual. These
figures, when used in conjunction with the station installation information and cable layout guide, should
provide all the information necessary to install additional Page/Party< stations.
Enclosure Placement
All GAI-Tronics Page/Party® units are wired in parallel. Good system layout design minimizes the cable
required for each installation. GAI-Tronics multi-conductor cable, designed especially for this application,
is recommended. The number, size, and color-coding of conductors are listed in the accompanying system
connection diagrams.
System layout and power cable length are very important when installing Page/Party< equipment.
Although it varies for different systems, the general guideline is that the total power cable length should not
exceed 1 mile (5280 feet) for 115 V ac systems. The total cable length is the most important consideration
while cable length between the stations is generally not a factor.

Mounting
The Model 703-104 Indoor EPL Amplifier Enclosure is not supplied with openings for conduit or cable
because the placement will vary according to the application. Drill or punch these openings using the
template supplied before mounting the enclosure. We highly recommend using only the bottom entry to
prevent moisture from dripping onto the terminals or PCBAs. The best location for conduit holes is along
the bottom of the enclosure near the rear surface. If the top opening is to be used, carefully seal around the
fitting to prevent moisture from entering.
For specific details including mounting hole dimensions, refer to Figure 1. There are four 5/16-inch
diameter mounting holes in the corners of the amplifier enclosure. The suggested mounting height for all
station enclosures is 54 inches (137 cm) to the centerline of the enclosure.
NOTE: Labels denoting which party line(s) is configured as the emergency party line are included in an
envelope inside the enclosure. The labels are for Party Line 1, Party Line 2, and Party Lines 1 and 2
configurations. Apply the appropriate label inside your enclosure.

Wiring
Attach the conduit to the enclosure. Feed the wiring through the conduit and bring it into the enclosure.
See Figure 2. Follow the wire colors carefully because the colors noted in the figure correspond to GAITronics 60029 Series multi-party cable. The wires must be spade-lugged and connected securely to the
terminal block. An improper termination can result in diminished station performance.
Local Muting
Figure 2 illustrates local speaker muting when stations are completely assembled and paging operation
occurs. Normally, when the station button is pressed, the paging speaker connected to that station is
silenced (muted) to prevent acoustic feedback to the handset microphone. However, while the handset is in
use for party line conversations, the paging speaker is “live” to enable paging calls from other stations.
To disable the mute feature, follow these instructions:
1. Locate the lugged violet wire attached to terminal point 7 (mute) on the terminal block within the
enclosure.
2. Transfer the lugged violet wire to terminal point 8 (Page L1).
After any muting changes are made, unpack the station amplifier and install.
Mutual Muting
In the event that feedback occurs within an area and repositioning of the system speakers does not help,
mutual muting may be used to correct this problem.
The following steps will mutually mute the adjacent amplifiers/handsets within a zone.
1. Ensure that the purple lugged wire is connected to terminal 7 of TB1.
2. Connect terminal TB1-7 of the handset station to TB1-7 of the station within the zone that is causing
feedback. This is done by using the spare system wire (orange conductor) from within the system
cable that runs between the stations.

Maintenance
Regular inspection and a good preventive maintenance program will increase the reliability of your
GAI-Tronics station. The GAI-Tronics Field Service Department can formulate a service contract suited
to your facility’s specific need for preventive maintenance. In addition, the following procedure can be
used to keep Page/Party® systems operating effectively.
WARNING
Before performing any of the following preventive maintenance steps, remove
all power from the station.
1. Remove the amplifier from the enclosure.
2. Visually check the interior of the enclosure for signs of contamination such as dust, condensation or
process liquid.
3. Using the No. 10440-002 Maintenance Cable, plug the amplifier into the connector in the enclosure.
Check, and if necessary, adjust the amplifier to maximize performance.
4. Reinstall the amplifier in the enclosure. Ensure that all gaskets and hardware are in place. Failure to
install the gaskets, which also act as spacers, can result in damage to the connectors on the amplifiers
and inside the enclosures and can cause system faults.
It may become necessary to re-terminate some or all of the enclosures in a system. If so, strip the wires
back to clean copper and connect only one wire to each connector to allow for easier future
troubleshooting.
If the equipment requires service, contact your Regional Service Center for a return authorization number
(RA#). Equipment should be shipped prepaid to GAI-Tronics with the return authorization number and a
purchase order number. If the equipment is under warranty, repairs will be made without charge. Please
include a written explanation of all defects to assist our technicians in their troubleshooting efforts. Call
800-492-1212 for help in identifying the Regional Service Center closest to you.
Troubleshooting
The following table lists some hints to aid technicians in troubleshooting.
Problem
Solution
Feedback
occurs only
during page.
1. If a speaker is close to the station, try using the muting feature in the amplifier
enclosure at the terminal blocks. Connect the violet wire at TB1-8 to TB1-7. Refer
to the wiring diagram.
2. Ensure that speakers attached to other stations located nearby are not pointed in your
direction. If changing the orientation of the other speakers has no effect, mutual
muting may be required. Mutual muting silences all the speakers within proximity to
the affected stations during a page from any one of the mutually muted stations.
Connect the orange wire (spare) to the TB1-7 of all the stations to be mutually
muted. Note: If too many stations are selected, paging coverage can be adversely
affected.
3. Check line terminations at the line balance assembly. Line balance assembly
connections are critical.
Crosstalk
occurs.
One or more system cable pairs may be improperly terminated. Visually inspect the
system cable connections for accidental crossing of the cable pairs or grounds.
