[. . . ] When installing an add-on station, consult the appropriate system layout diagrams. 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. Enclosure Placement All GAI-Tronics Page/Party® units are wired in parallel. Good system layout design minimizes the cable required for each installation. GAI-Tronics multi-conductor cable, designed especially for this application, is recommended. [. . . ] 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. Perform the following steps to mutually mute adjacent amplifiers/handsets within a zone. Ensure that the purple lugged wire is connected to terminal 7 of TB1. 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\42004-370c. doc 11/10 Model 7325-106 Multi-Party Amplifier Enclosure Pub.

The GAI-Tronics Field Service Department can formulate a service contract suited to your facility's specific need for preventive maintenance. In addition, the following procedure can be used to keep Page/Party® systems operating effectively. WARNING Before performing any of the following preventive maintenance steps, remove all power from the station. Remove the amplifier from the enclosure. Visually check the interior of the enclosure for signs of contamination such as dust, condensation or process liquid. 10440-002 Maintenance Cable, plug the amplifier into the connector in the enclosure. Check, and if necessary, adjust the amplifier to maximize performance. Reinstall the amplifier in the enclosure. Ensure that all gaskets and hardware are in place. Failure to install the gaskets, which also act as spacers, can result in damage to the connectors on the amplifiers and inside the enclosures and can cause system faults. It may become necessary to re-terminate some or all of the enclosures in a system. If so, strip the wires back to clean copper and connect only one wire to each connector to allow for easier future troubleshooting. Troubleshooting The following table lists some hints to aid technicians in troubleshooting. Problem Solution Feedback occurs only during page. 1. If a speaker is close to the station, try using the muting feature in the amplifier enclosure at the terminal blocks. [. . . ] manuals\42004-370c. doc 11/10 Warranty Equipment.
