General Information
The following GAI-Tronics amplifier enclosures are covered in this manual:
Model
Description
703-002
Indoor Amplifier Enclosure, 24 V dc input
7335-002
Weatherproof Non-metallic Amplifier Enclosure; 24 V dc input
The amplifier enclosure is an important component of the 700 Series Page/Party
®
System. These
enclosures are configured for multi-party systems and can accommodate conversations on up to five party
lines simultaneously. The Model 703-002 Indoor Amplifier Enclosure is made of fabricated steel. The
Model 7335-002 Outdoor Enclosure is made of weatherproof and corrosion-resistant glass-reinforced
polyester. Both types of enclosures are equipped with terminal strips for connecting inter-station cable.
The Model 701 Series Amplifiers mate directly with these enclosures.
Installation
The GAI-Tronics 24 V dc series of Page/Party
®
system equipment is designed to operate from a 24 volt dc
rechargeable battery. A battery charger may be connected to the battery to maintain the charge.
CAUTION
Under NO condition should this equipment be operated from a battery charger without the batteries
connected.
Most chargers have an unloaded output of 35 to 45 volts which can quickly damage the equipment designed
for nominal 24 volts. To maintain a proper state of battery charge, the voltage across the batteries will be
somewhat greater than 24 volts, but should never exceed 28.8 V dc.
Grounding the negative side of the battery system at only one point is recommended and will ensure hum-
and noise-free operation.
