V-1055 
45 OHM TALKBACK CORNER SPEAKER 
 
 
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 
“keyhole” slot for mounting (see figure 1).  After 
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 
as follows: 
•  Speaker out from page control to speaker tip 
•  Speaker common to speaker ring 
 
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.
