Reply Distance
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 will
cover 600 square feet (Talkback from 25') and a
ceiling speaker will cover 250 square feet
(Talkback from 10').
REMEMBER: 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 talkback page equipment will not
function in a satisfactory manner.
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 production
equipment such as fans, air conditioners,
machinery, or compressors.

Speaker Power Requirements
Valcom Talkback Speakers do not require
power.
Valcom Power Units
Each page control/interface, one-way speaker
and peripheral device has been assigned a
Valcom power unit (VPU) value. Each product
either provides a power output (+) or consumes
power (-). Products that neither require, nor
provide, power are indicated by a VPU of zero
(0). After you have chosen the page control
interface, speakers and accessories for your
application, simply add up all of the Valcom
Power Units. If you come out even or have
power left over, your paging system is complete.
However, if you come out with more VPUs
required than provided, you will need additional
power.
The additional power required will be provided by
adding one or more Valcom power supplies as
listed in table 2.
