General Information
The Model 758-002 Weatherproof Speaker Amplifier Enclosure is an important component of the 700
Series Page/Party
 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 24 V dc input systems, and is equipped with terminal strips for connecting
inter-station system cable. The GAI-Tronics Model 751-002 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 “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 24 V dc 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.
In 24-volt systems, plan on several branch lines from the dc source with no more than six stations per
branch. One branch could span up to 4,000 feet for a single station. The Maximum Cable Distance
Table lists the limits. Where two or more stations are listed, the assumption is that they are evenly
spaced along the cable.
Each amplifier contains two fuses on the PCBA in the 24 V dc input to protect and isolate the handset
and speaker amplifier circuitry in the event of a failure. Power line wiring to each amplifier or group of
amplifiers should have a fuse or circuit-breaker to protect against wiring failures.
