General Information  
The Model 758-001 Weatherproof Speaker Amplifier Enclosure is an important component of the 700  
Series Page/Partyd system. It is constructed of cast aluminum alloy, which is extremely weatherproof  
and corrosion-resistant, and can be used in either indoor or outdoor applications.  
This enclosure is designed for 115 V ac input systems, and is equipped with terminal strips for connecting  
inter-station system cable. The GAI-Tronics Model 751-001 Speaker Amplifier mates directly into this  
enclosure.  
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/Partyd stations.

Wiring  
Attach 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 or 60038  
Series cable. The wires must be spade-lugged and connected carefully and completely to the terminal  
block. An improper termination may diminish station performance.  
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 on the Model 758-001 Enclosure is connected to terminal 7 of  
TB1.  
2. Connect terminal TB1-7 of the handset station to TB1-7 of the Model 758-002 Enclosure 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.  
Troubleshooting  
The following table lists some hints to aid technicians in troubleshooting.  
Problem  
Solution  
Feedback occurs 1. If a speaker is close to the station, try using the muting feature in the amplifier  
only during  
page.  
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.
