GAITronics retains all intellectual property and other rights in or to the information contained herein, and such information may only be used in connection with the operation of your GAI-Tronics product or system. This manual may not be disclosed in any form, in whole or in part, directly or indirectly, to any third party. General Information The Model 7325-107 RTU (Remote Terminal Unit) Outdoor Metallic Enclosure is designed to be a component in GAI-Tronics SmartSeries system. It mates with a SmartSeries handset or speaker amplifier to form a SmartSeries station. [. . . ] The number, size, and color-coding of conductors are listed in the system connection diagram. System layout and power cable length are very important when installing Page/Party equipment. Although it varies for different systems, the general guideline is that the total power cable length should not exceed one mile (5280 feet) for 120 V ac systems. The total cable length is the most important consideration while cable length between the stations is generally not a factor. Mounting The Model 7325-107 Outdoor Metallic RTU Enclosure is supplied with top and bottom openings for conduit. We highly recommend using only the bottom opening. This helps to prevent water from leaking in through the opening or trapped moisture from entering through the conduit. If the top opening must be used, carefully seal around the fitting to prevent moisture from entering. For specific mounting details, refer to Figure 6. There are four 0. 438-inch diameter mounting holes in the corners of the amplifier enclosure. The suggested mounting height for all station enclosures is 54 inches (137 cm) up to the centerline of the enclosure. If supplied with plain entry holes for gland entry: · · The gland or stopping plug is secured internally by a locknut, such that the gland or stopping plug will not be dislodged by a 7 N-m impact. The enclosure will be maintained at IP 66 by a suitable sealing washer under the shoulder of the cable gland. For continued IP 66 protection, torque setting for securing the amplifier to the enclosure should be 10 to 12 in-lbs. or 1. 13 to 1. 36 N-m. f:\standard ioms - current release\42004 instr. manuals\42004-689l2b. doc 11/10 Model 7325-107 SmartSeries Outdoor Metallic RTU Enclosure Pub.

Follow the wire colors carefully because the colors noted in the figure correspond to GAI-Tronics multi-party cable. The wires must be spade-lugged and connected securely to the terminal block. An improper termination may result in diminished station performance. CAUTION For safe operation, connect terminal 3 of TB1 to system ground. See Figure 1. Local Muting Figure 1 illustrates local speaker muting when stations are completely assembled and paging operation occurs.
