General Information and Available Options
This guide covers the installation of the 7245-004 Indoor Remote Subset Amplifier Enclosure, which is intended for use in GAI-
Tronics Page/Party ® and SmartSeries systems. This enclosure enables the amplifier, speaker, and field cabling of subset stations to be
remotely mounted. It is constructed of fabricated steel and is equipped with a 24-position remote subset connector.
Refer to Pub. 42004-644L2 at the “Manuals & Specs” link at
www.gai-tronics.com for a list of subsets, system planning guidelines,
detailed explanations and warranty.
Mounting and Connection
WARNING Do not install this equipment in hazardous areas. Such installations may cause a safety hazard and consequent injury or
property damage.
N OTE : The GAI-Tronics subsets designed for use with this enclosure contain 8-foot (244 cm) connectorized cables. This enclosure
must be mounted within reach of these cables.
Mounting - The 7245-004 Indoor Enclosure is not supplied with openings for conduit or cable. 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.
There are four 0.312-inch diameter mounting holes in the corners of the amplifier enclosure. See Figure 1 for hole pattern dimensions.
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 1 to comply with NRTL requirements.
Wiring - Feed the system wiring into the enclosure. Strip the insulation on each conductor of the system cable. Install a ring lug on
the ground conductor (GRN/YW wire). The wires must be spade-lugged and connected carefully and completely to the terminal
blocks in accordance with the colors indicated in Figure 2. An improper termination may result in diminished station performance.
Feed the speaker wiring into the enclosure. Strip the insulation on each conductor of the speaker cable. Install spade lugs on each
conductor. Connect the speaker wires of an 8-ohm speaker between the TB1-4 (speaker common) and TB1-5 (8-ohm) or connect the
speaker wires of a 16-ohm speaker between the TB1-4 (speaker common) and TB1-6 (16-ohm).
1. Set the speaker muting control to the desired location. Refer to the Local Muting and Mutual Muting sections for details.
2. Plug the subset connector into the J2 receptacle located at the bottom of the enclosure. Secure the connector with the connector
guard and screws provided. See Figure 1.
3. Insert the plug-in amplifier into the J1 receptacle of the enclosure and secure the amplifier with four screws.
The following table lists some hints to aid technicians in troubleshooting:
Problem Solution
Feedback occurs
only during page. Use the muting feature in the amplifier enclosure at the terminal blocks. Connect the violet wire at terminal 8 to
terminal 7, or reposition the speaker. In some cases, the speaker of a nearby station may have to be repositioned.
Crosstalk occurs. One or more system cable pairs may be improperly terminated or a fault exists somewhere else in the system.
Visually inspect the system cable connections for accidental crossing of the cable pairs or grounds.
