Mounting and Connection

WARNING

property damage.

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 d etails.

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.

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.

Problem Solution

Remote subset is
inoperable.

 Verify that the connector of the remote subset is securely connected to the subset receptacle of the enclosure.
 Remove the amplifier from the enclosure. Re-install the amplifier ensuring the enclosure connector and the

amplifier connector are aligned properly.

Auxiliary inputs do
not operate.

 Remove the amplifier and verify the lugged auxiliary input wires are properly terminated on terminal points

TB1-10 and TB1-11 respectively.

 Verify the auxiliary inputs have been enabled in the system software.
