When using the GAI-Tronics Model 13351 Integral Speaker, connect the incoming conductors to the
labeled terminal block inside the unit according to the desired wattage tap.
Speaker Muting
The Model 10461-002 Card Rack and Model 69037-101 Line Cards are factory-set so that all associated
speakers broadcast pages made on the system. However, if a speaker is located too close to a handset,
acoustic coupling may occur during a page from that handset and cause feedback over the entire system.
To eliminate this problem, the speaker can be muted by cutting the blue wire that loops from pin 2 to pin
10 on the connector that the station card plugs into. These blue jumpers are found on each connector in
the rack.
N OTE : This muting procedure affects handset pages only, and does not affect alarm signals.
This procedure is permanent once completed. If temporary muting is required, contact your GAI-Tronics
Service Center for additional information.
Operation
The card rack itself has no user operation functions. Refer to the individual component manuals for
specific operational instructions.
