Common Areas

Common areas are those areas that are comprised of multiple one-way speakers

(typically no talkback capability). Examples of such areas include hallways,

cafeterias, gymnasiums and outside areas. Self-amplified speakers should be

used for your common areas with all

Valcom MultiPath intercom systems.

One-way self-amplified speakers may be connected to either V-TCM or XP-

TCM12 Talkback Intercom Expansion Cards (by adding an appropriate interface

device per zone) or V-STX 24 Point One Way Paging Expansion Cards. V-STX

cards, although better suited for one-way zones, are not necessarily required. If

your application includes 10 or more one-way zones, then the addition of one or

more V-STX cards should be considered.

Ceiling speakers in common areas should be spaced at twice the ceiling height.

Wall speakers should be spaced 20 feet apart and cover approximately 600

square feet each.
