INTRODUCTION
The interior corner speaker, the V-1055 is a 8”
interior talkback speaker for use with Valcom
“Handsfree” talkback page control units. The
enclosure is made of steel with a durable powder
coated finish. The color of the enclosure can
easily be changed to match any decor. A cloth
covered detachable grille is included.
Mounting
Remove cloth covered grille from baffle. Place
speaker in the desired mounting location. Mark

making the required connections, secure baffle to
wall with a suitable mounting screw (#10 sheet
metal screw or similar). Attach cloth covered
grille to baffle.
Connections
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

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
Consult Valcom's VSP - Handsfree Talkback
Paging (Part # 947099) for detailed information on
selecting the control unit and power supply.
