INTRODUCTION  
The V-1070 is a surface mounted speaker that  
is used with Valcom “Handsfree” Talkback Page  
Control units. The speaker is designed for  
interior use only. The baffle is designed for  
mounting on acoustic tile, such as those  
normally found in suspended-ceilings and can  
be mounted without cutting large holes in the  
tile. The mounting pins can be removed for  
mounting in a hard ceiling. The speaker  
housing has screw holes for securing speaker  
without mounting pins. Although the

through hole to connect to speaker.  
3. Make connections to speaker.  
4. Install the speaker by inserting the mounting

speaker in place.  
P-TEC speakers are designed specifically for  
standard suspended ceilings, they can be used  
on many types of ceiling materials.  
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.  
5. Place the speaker mounting clips over  
mounting pins (so pins slide through clips).  
A standard Valcom talkback paging system is  
made up of three basic components:  
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:  
1. A talkback page control unit  
2. Speakers (45 Ohm)  
3. A power supply  
Speaker out from page control to speaker tip  
Speaker common to speaker ring  
Consult Valcom's VSP - Handsfree Talkback  
Paging (Part # 947099) for detailed information  
on selecting the control unit and power supply.  
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.
