WARNING Do not mount the enclosure with hinges on the top or bottom side.
Securely fasten the enclosure to the mounting location, using 1/2-inch diameter steel mounting bolts and
washers, or washer head bolts.
WARNING Do not disconnect equipment while energized.
Insure proper grounding to protective earthing.
Inspect and clean the machined flange flame joint surfaces of both the cover and box. Surfaces must be
smooth, free of nicks, scratches, dirt or any foreign particle build-up that would prevent a proper seal.
Surfaces must seat fully against each other to provide a proper explosion-proof joint. Clean surfaces by
wiping with a clean lint-free cloth.
Apply a light coat of Killark “LUBG” lubricant to flange surfaces and close the cover. Install and tighten
all cover bolts to 30 ft-lbs. Make certain no cover bolts are omitted. Use only those bolts supplied with the
enclosure.
When installing an add-on station, consult the appropriate system layout diagrams. 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. For the number, size, and color-coding of conductors refer to the appropriate 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 one mile (5280 feet) for 120 V ac systems. The total cable length is the most important
consideration while cable length between the stations is generally not a factor.

Internal
The speaker amplifier enclosure contains two terminal blocks, an interior mounting plate, an amplifier
bridging plate, and a connector for the mating Model 709-901 Amplifier. The amplifier bridging plate is
hinged on one side and attached on the opposite side with two #10-32 screws. For system cable
installation, the screws to this plate must be removed and the bridging plate swung open 90º. Upon
installation of the wiring cable, the amplifier bridging plate can be rotated closed and reattached with the
two #10-32 screws. This plate will then serve as a protection for the amplifier and the switches from the
system cable when the unit is completely closed. Refer to Figure 3.

Wiring
Attach the conduit or cable glands to the enclosure. Feed the wiring through these and bring it into the
enclosure. Attach the wires to the terminal blocks located behind the amplifier bridging plate. Follow the
wire colors carefully because the colors correspond to GAI-Tronics cable. The wires must be spade-lugged
and connected carefully and completely to the terminal block. An improper termination may result in
diminished station performance. See Figure 6.
CAUTION
For safe operation, connect terminal 3 of TB1 to system ground.
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.
Use the following steps to mutually mute 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.
CAUTION
To reduce the risk of ignition of hazardous atmospheres, disconnect the equipment from the supply
circuit before making any adjustments to the amplifier's handset level.
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.
Inspect and clean the machined flange flame joint surfaces of both the cover and box. Surfaces must be
smooth, free of nicks, scratches, dirt or any foreign particle build-up that would prevent a proper seal.
Surfaces must seat fully against each other to provide a proper explosion-proof joint. Clean surfaces by
wiping with a clean lint-free cloth.
Apply a light coat of Killark “LUBG” lubricant to flange surfaces and close the cover. Install and tighten
all cover bolts to 30 ft-lbs. Make certain no cover bolts are omitted. Use only those bolts supplied with the
enclosure.
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.
NOTE:Refer to the Killark Installation, Operation, and Maintenance Data Sheet enclosed with the unit for
additional information.

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.
