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.
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.
