General Information This manual applies to the following GAI-Tronics amplifier enclosures: Model Description 703-002 7325-102 7335-002 Indoor Amplifier Enclosure; multi-party, 24 V dc input Weatherproof Aluminum Enclosure; multi-party, 24 V dc input Weatherproof Non-metallic Amplifier Enclosure; multi-party, 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. [. . . ] Under no circumstances should cable entries be made in the side of the enclosure as this may interfere with the installation of the plug-in amplifier. For specific details including mounting hole dimensions, refer to Figure 1 for the Model 703-002 Indoor Enclosure, Figure 2 for Model 7335-002 Weatherproof Non-metallic Enclosure, and Figure 3 for the Model 7325-102 Weatherproof Metallic Enclosure. When mounting the enclosure, use caution to avoid damaging the terminal blocks inside. The suggested mounting height for all station enclosures is 54 inches (137 cm) up to the centerline of the enclosure. Figure 1.

Feed the wiring through the conduit, and bring it into the enclosure. Follow the wire colors carefully, because the colors correspond to GAI-Tronics 60029 Series multi-party cable. The wires must be spade-lugged and connected carefully and completely to the terminal block. An improper termination may diminish station performance. Local Muting Figure 4 illustrates local speaker muting when stations are completely assembled and paging operation occurs. Normally, when the station button is pressed, the paging speaker connected to that station is silenced (muted) to prevent acoustic feedback to the handset microphone. However, while the handset is in use for party line conversations, the paging speaker is "live" to enable paging calls from other stations. To disable the mute feature, follow these instructions: 1. Locate the lugged violet wire attached to terminal point 7 (Mute) on the terminal block within the enclosure. Transfer the lugged violet wire to terminal point 8 (Page L1). After any muting changes are made, unpack the station amplifier and install. 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 mute adjacent amplifiers/handsets within a zone.
