V-1070
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.

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.
