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 single party enclosures contain 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 7.

CAUTION

For safe operation, connect terminal 3 of TB1 to system ground.

Local Muting

Figure 7 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 mutually mutes 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.

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.
