General Information The Model 7245-003 Indoor Remote Subset Amplifier Enclosure is an important component of the 700 Series Page/Party® System. It is constructed of fabricated steel, and is equipped with terminal strips for connecting inter-station cable and a 24-pin connector to accommodate one of three types of GAI-Tronics subsets. [. . . ] Drill or punch these openings using the supplied template before mounting the enclosure. The best location for the conduit holes is along the top or bottom of the enclosure and near the rear surface. Avoid the top center as it may interfere with the plug-in amplifier receptacle. In extreme environments, extra precautions should be taken to improve system reliability. Whenever possible, do not install conduit from the top. Side or bottom entry helps to prevent moisture from dripping onto the terminals or printed circuit boards. There are four 0. 312-inch diameter mounting holes in the corners of the amplifier enclosure. When mounting the enclosure, use caution to avoid damaging the terminal blocks inside. Install the connector guard over the remote cable plug using the screws provided as shown in Figure 3 to comply with NRTL requirements. f:\standard ioms - current release\42004 instr. manuals\42004-261e. doc 11/10 Model 7245-003 24 V DC Remote Subset Amplifier Enclosure Pub.

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 or 60038 Series multi-party cable. The wires must be spade-lugged and connected carefully and completely to the terminal block. An improper termination may result in diminished station performance. Set the speaker muting control to the desired location. Refer to the Local Muting and Mutual Muting sections for details. Plug the subset connector into the receptacle located at the bottom of the enclosure. Secure the connector with the connector guard and screws provided. Insert the plug-in amplifier into the enclosure and secure the amplifier with four screws. Local Muting Figure 4 illustrates local speaker muting when stations are completely assembled and paging operation occurs.
