Valcom V2924A User Manual

TALKBACK INTERCOM SYSTEM
The basic V-2924A Talkback Intercom System provides 24 stations with one-way, two-way, group call and all call
pages. The V-2925A Expansion Unit is an add on unit for the V-2924A. Each V-2925A Expansion Unit will
expand the V-2924A by twenty-four (24) additional stations. Up to three (3) Expansion Units can be added to a
system for a total of 48, 72, or 96 zones of paging.
The V-2925A can ONLY be used with the V-2924A. If you have the V-2924 model, please contact Technical
Support for assistance.
WARNING: Disconnect main power before servicing.
Mounting
Plug the Expansion Unit into the Control Unit. For the first Expansion Unit, insert the P1 connector from the
Expansion Unit into the P8 connector on the Control Unit (Refer to Figure 1 for location of connectors). (For
each additional Expansion Unit, insert P2 into P1 – Refer to Figure 1 of the Control Unit document).
Close latches attached to the top and bottom of the Expansion Unit over the keepers on the top and bottom of
the Control Unit.
Drill holes into backboard through mounting flanges on the Expansion Unit.
Insert screws into holes and tighten screws firmly.
Connections
Each Expansion Unit requires (2) 66B type punchdown blocks. Mount these on the backboard near the associated
Expansion Unit. Make connections to the punchdown blocks as specified in Figure 2 – Punchdown Block
Connections.
Setting Option Switches
All options programmed for the Control Unit are available on the additional stations provided by the Expansion
Units. The only switches on the Expansion Unit requiring attention are those for Background Music. Refer to
