P-TEC SURFACE MOUNT

 

TALKBACK CEILING SPEAKER 

 

 

 

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 
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. 
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. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 

 
 
 
 
 
 

Dimensions/Weight    

  8.00” Dia x 2.50” H (20.32cm x 6.35cm)  

  0.75 lbs.  0(.34 kg) 

 

INSTALLATION 

(

see Figure 1

)

 

 

1.  Lift the adjacent ceiling tile and slide it out of 

the way.  

2. 

Pierce hole in tile where speaker is to be 
mounted with a screwdriver.  Feed wire 
through hole to connect to speaker.

 

3. 

Make connections to speaker.

 

4. 

Install the speaker by inserting the mounting 
pins through the ceiling tile and hold the 
speaker in place.

 

5. 

Place the speaker mounting clips over 
mounting pins (so pins slide through clips).

 

 

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 

 

 

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. 
 
Use common sense 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 
producing equipment such as fans, air conditioners, 
machinery or compressors.
