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.

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.
