ADVANTAGES OF DISTRIBUTED AMPLIFIED SYSTEMS

 Low voltage, therefore existing telephone cable (Class 2 wiring) can be used to eliminate costly

outside plant or indoor conduit.

 Low voltage operation means much less power dissipation (heat), therefore the longevity of the

paging equipment is increased dramatically.

 Multizone capability of 96 zones from a single trunk port. (Up to 576 Zones with All Call with multiple

systems connected for Global All Call – Call Valcom Technical Support for assistance)

 Talkback, one-way or combination systems are easy to configure.

 Individual volume controls built-in to each one-way speaker for volume adjustment after system is

installed.

 It is cost-effective to install one telephone cable versus installing both telephone cable and 70 volt

shielded paging cable.

 Unlimited one-way speaker expansion since each speaker is self-amplified.

 Jobs requiring explosion-proof systems are easily accommodated.

 Amplified one-way speakers can interface 70 volt systems without changing or adding central

amplifier.

 Many localities require conduit for "high voltage" (Class 1) conductors, this is rarely a necessity with a

distributed amplified system.

 The rated output of a distributed amplified paging speaker or horn is always available due to the fact

that the actual audio signal amplification is accomplished on an individual basis. In a 70 volt system,

the rated output is only available if the central amplifier is actually providing a full 70 volts to the

speaker or horn and the audio signal line losses are negligible.

 Background music is unaffected in zones that are not currently being paged.
