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.

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
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 eight feet from the floor.
Ceiling speaker (V-1060A, V-1060B) coverage is
dependent on ceiling height; the greater the ceiling
height, the larger the area covered.

Limitations
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).
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.
TROUBLESHOOTING CHART

ACTIONS
No sound in page mode
Check tip and ring for audio at speaker.
Check tip and ring for audio at control unit.
Low sound in page mode
Check volume controls at page control.
Poor listening in talkback mode
No LED indication (on V-1060B)

INSTALLATION
Connections
Two conductor (four conductor for V-1060B
only) 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
For 1060B only:
Switched -24VDC to -24VDC (LED)
Power Supply ground to GND (LED)
Mounting
CEILING SPEAKERS: 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.
WALL SPEAKERS: 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.
CORNER SPEAKERS: 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.
CORRIDOR SPEAKERS: 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.
