SYSTEM DESIGN
General
The 45 ohm Talkback Speakers are designed to be
used with the Valcom "handsfree" talkback control
units. In combination with these units, they will
provide both loudspeaker and talkback functions.
A standard Valcom talkback paging system is made
up of three basic components:
1. A talkback page control unit.
2. Speakers (45 ohm)
3. A power supply.
Consult Valcom's VSP - Handsfree Talkback Paging
(P/N 947099) for detailed information on selecting
the control unit and power supply.
Coverage
The distance you can be away from a speaker and still
have good talkback depends on the type of speaker
and the ambient noise level. In a typical office
environment, a wall speaker (V-1061-W,
V-1061-BK, V-1062A, V-1063A, V-1064A,
V-1065A, V-1066A, V-1067A) will cover
approximately 600 square feet when mounted 8' from
the floor. Ceiling speaker coverage is dependent on
ceiling height; the greater the ceiling height, the
larger the area covered.

IMPORTANT
The speaker is no better than your ears. If you
cannot carry on a conversation at normal voice
levels over the required talkback distance, then
the talkback page equipment will not function
satisfactorily.
Use common sense when mounting a talkback
speaker. The speaker should be as close as
possible to the area where talkback is desired.
It should not be mounted close to, or pointed at,
noise producing equipment such as fans, air
conditioners, machinery, or compressors.

Limitations
• Two talkback speakers maximum per zone unless
V-9922A talkback speaker selection units are
used. Refer to the next section for details.
• Two talkback plus 40 one-way amplified
speakers maximum per zone when mixing
talkback and one-way paging.
• 800 feet maximum cable length to speaker from
page control.
NOTE: Do not split pairs to speakers.
• Do not use talkback in noisy areas (80db or
greater).
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
Technical Support at (540) 427-3900 for additional
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" dia. 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.
