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.
