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 with
LED indication.

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.

Although the "B" series 45 Ohm Talkback Interior
Speakers with LED can be used with all Valcom
Talkback Control Units, consult Valcom's VSP
Handsfree Talkback Paging (947100) for detailed
information on selecting the control unit and power
supply.

NOTE: Only the Valcom V-1109RTHF and V­9921HF provide provisions for activating the LED.

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-1062B, V­1064B, V-1066B) will cover approximately 600
square feet (talkback from 25') and a ceiling speaker
(V-1060B) will cover approximately 250 square feet
when mounted 8' from the floor (talkback from 10').
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
