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 only be used in connection with the operation of your GAI-Tronics product or system. This manual may not be disclosed in any form, in whole or in part, directly or indirectly, to any third party.

General Information

The Model 7325-104 Outdoor Metallic 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, this 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.

N OTES :

1. The Model 7325-104 Enclosure can also mate with a standard 701 or 751 Series Amplifier; however the reporting feature is not operable with this combination.

2. Emergency party line 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 as to the capabilities of your system, please contact your nearest GAI-Tronics Service

Center.

Installation

Page: 2 of 8

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 one 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 7325-104 Weatherproof Metallic Enclosure is supplied with pre-drilled cable openings and conduit hubs with top and bottom cap plugs in place to prevent contamination. Whenever possible, do not enter an enclosure from the top. 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 7/16-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.

N OTE : 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

Remove plastic plugs and install conduit to the enclosure. 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 correspond to GAI-Tronics 60029 Series multi-party cable. The wires must be spadelugged 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.
