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.

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

Coverage

The distance you can be away from a speaker and still have good talkback depends on the type of speaker and the ambient noise level. In a typical office environment, a wall speaker (V-1061-W, V-1061-BK, V-1062A, V-1063A, V-1064A, V-1065A, V-1066A, V-1067A) will cover approximately 600 square feet when mounted eight feet from the floor. Ceiling speaker (V-1060A, V-1060B) coverage is dependent on ceiling height; the greater the ceiling height, the larger the area covered.

Limitations

Two talkback plus 40 one-way amplified speakers

maximum per zone when mixing talkback and one-way paging.

800 feet maximum cable length to speaker from

page control.

NOTE: Do not split pairs to speakers.

Do not use talkback in noisy areas (80dB or

greater).

Valcom recommends that the total number of speakers per talkback zone be limited to two talkback and forty one-way self-amplified speakers. The reasoning behind this recommendation is simple. Whenever a page is made into a talkback zone, the paging party will hear audio from all of the talkback speakers in that zone. If a zone contains more than two talkback speakers, the talkback audio from the "extra" speakers will impede the quality of the talkback audio from the desired speaker. Additionally, there are limits to the number of talkback speakers that a page control will actually drive. Ideally, if a page were made into a talkback zone, all of the speakers would simply act like "one-way" speakers except for the one that is closest to the paged person.
