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 V-
9921HF 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, V-
1064B, 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
