the nature of talkback paging with station level
access from various C.O. lines or PABX/PBX
stations, it is advisable to contact Technical Support
prior to configuring your system.
Mixing Talkback and One-Way Paging
When using a Talkback Control Unit, one-way and
talkback zones may be mixed on the same control
unit. The outgoing page on a talkback zone may also
be expanded by adding one-way speakers.
To make a zone one-way, simply add a V-1092
volume control and Valcom one-way amplified
speakers to that zone (maximum 40 per zone).
To expand the outgoing page on a talkback zone,
wire one-way amplified speakers in parallel with the
talkback speakers on that zone (maximum 40 per
zone). Of course, when you do this you still will
only be receiving talkback from the 45 ohm talkback
speakers on the zone.
NOTE: When using one-way amplified
speaker assemblies on a talkback control
unit, a V-1092 Volume Control or a V-1094A
Page Port Preamp may be used to attenuate
the high level talkback audio level prior its
appearance at the audio input of the one-way
speakers (talkback audio is substantially
higher in level in comparison to one-way
audio).
