VALCOM TALKBACK PENDANT SPEAKERS
Valcom Talkback Pendant Speaker, V-1019B, is a 45-ohm talkback speaker designed
to be used with Valcom "handsfree" talkback control units. The distance you can
be away from the speaker and still have good talkback depends on the ambient
noise level. The speaker is weather-resistant and is available in white, black and
gray.

INSTALLATION
The V-1019B Talkback Pendant Speaker is
designed to be suspended from a ceiling using
the enclosed chain. The chain is not attached
to the ring at the top of the speaker to prevent
damage to the speaker's finish during shipping.
To install the chain, open the link on the end of
the chain and loop the link through the ring
located on the top of the speaker and close the
link. Make sure the chain is securely fastened
to the ceiling.
NOTE: An additional 6 feet length of chain is
available. Order Part Number V-1093-BK.
COVERAGE
The distance you can be away from a speaker
and still have good talkback depends on the
ambient noise level. The pendant speaker will
cover approximately 250 square feet when
mounted 8' from the floor (talkback from 10'). Speaker coverage is dependent on
mounting height; the greater the mounting height, the larger the area covered.
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 satisfactorily.
CONNECTIONS
Note:
The cable is for electrical connections only. Under no circumstances
should the speaker be suspended from this cable.
Two conductor 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.
LIMITATIONS
•
Two talkback speakers maximum per zone. When mixing talkback and one-way
paging, use a maximum of two talkback and forty one-way speakers per zone.
•
800 feet maximum cable length to speaker from page control. Do not split pairs
to speakers.
•
Do not use talkback in noisy areas (80dB or greater).
•
Do not mount close to, or point at, noise production equipment such as fans,
air conditioners, machinery or compressors.
