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.
