COM FOR PRODUCT LITERATURE AND MANUALS Model 703-002, 7325-102, and 7335-002 Multi-Party 24 V DC Amplifier Enclosures Pub. 42004-141F Page: 2 of 12 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. [. . . ] 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.

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. Locate the lugged violet wire attached to terminal point 7 (Mute) on the terminal block within the enclosure. 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. Connect terminal TB1-7 of the handset station to TB1-7 of the station within the zone that is causing feedback. This is done by using the spare system wire (orange conductor) from within the system cable that runs between the stations. f:\standard ioms - current release\42004 instr. manuals\42004-141f. doc 11/10 Model 703-002, 7325-102, and 7335-002 Multi-Party 24 V DC Amplifier Enclosures Pub. manuals\42004-141f. doc 11/10 Model 703-002, 7325-102, and 7335-002 Multi-Party 24 V DC Amplifier Enclosures Pub.
