V-9922A Talkback Speaker Selection
Units
Valcom recommends that the total number of speakers
per talkback zone be limited to two talkback and forty
one-way self-amplified speakers. The reasoning
behind this recommendation is simple. Whenever a
page is made into a talkback zone, the paging party
will hear audio from all of the talkback speakers in that
zone. If a zone contains more than two talkback
speakers, the talkback audio from the "extra" speakers
will impede the quality of the talkback audio from the
desired speaker. Additionally, there are limits to the
number of talkback speakers that a page control will
actually drive.
Ideally, if a page were made into a talkback zone, all of
the speakers would simply act like "one-way"
speakers except for the one that is closest to the
paged person. Talkback capability can be provided
by utilizing a V-9922A, Talkback Speaker Selection
Unit, for each talkback speaker. A V-9928, Wall
Mount 5 Watt Amplifier, is also required for every six
(6) talkback speakers.
When a page is made, all speakers provide one-way
announcement. In order to respond, the paged party
activates the closest speaker with a press of the
push-button of that speakers associated talkback
speaker selection unit. This activates the chosen
speaker as a talkback speaker and resets any
previously selected speaker. Contact Valcom

information.
INSTALLATION
Connections
Two conductor twisted wire is required for the 45
Ohm talkback speakers. Standard 22 or 24 gauge
station wire is acceptable. Shielded wire is not
required or recommended. Connections are as
follows:
•
Speaker out from page control to speaker tip
•
Speaker common to speaker ring
Mounting
V-1060A: Cut an 8.5" diameter hole in ceiling tile.
After connections have been made to the speaker,
attach speaker to ceiling tile using the mounting
hardware provided. NOTE: Where extra speaker
support is needed, a V-9916 or V-9916M Valcom
Bridge and Backbox should be used.
V-1061-BK, V-1061-W, V-1062A, V-1063A: After
making the required connections, fasten a suitable
mounting screw (#10 sheet metal screw or similar) to
the wall at the desired location for mounting of the
speaker. Hang the speaker on the screw using the
keyhole on the speaker bracket.
V-1064A, V-1065A: After making the required
connections to the speaker, use appropriate hardware
such as an 8d finishing nail and hang the speaker in
the corner. Typical mounting height would be 8 feet.
V-1066A, V-1067A: Unscrew mounting bracket and
baffle from speaker assembly. Using appropriate
hardware, mount the bracket to the wall. After making
the required connections, reattach the baffle to the
speaker and the speaker to the mounting bracket.
