General Information
This manual applies to the GAI-Tronics 703A Multi-Party Indoor 120 V AC Amplifier Enclosure, which
is an important component of the 700 series Page/Party
 system. This enclosure is configured for multi-
party systems and can accommodate conversations on up to five party lines simultaneously.
The 703A Enclosure is constructed of fabricated steel, and is equipped with terminal strips for connecting
system cable. The 701 and 751 series amplifiers mate directly with this enclosure.
Installation
CAUTION
Do not install this equipment in hazardous areas other than those indicated
on the approval listing in the “Specifications” 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 diagram at the end of this manual. This
figure, 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 diagram.
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 120 V ac systems. The total cable length is the most important
consideration while cable length between the stations is generally not a factor.
