The speakers may be any Valcom amplified
speaker or horn. The quantity of speakers
required depends on several factures including
the type of speaker and the environment it will be
used in. Please refer to the Installation section of
this document for details.
Power unit requirements for all Valcom speakers
are listed with each speaker model on the Valcom
website. Please refer to www.valcom.com for
specific power requirements for each style of
speaker.
Valcom Power Units
Each page control/interface, speaker and
peripheral device has been assigned a Valcom
power unit (VPU) value. Products that provide
power, such as the 2000 Series page
control/interfaces or power supplies, have power
unit values indicated with a plus (+) sign.
Products that consume power have power unit
values indicated with a minus (-) sign. Products
that neither require nor provide power are
indicated by a VPU of zero (0).
After you have chosen the page control interface,
speakers and accessories for your application,
simply add up all of the Valcom power units
[indicated by a minus (-)] for each item that
requires power. This total tells you how much
power you need. If you have chosen a 2000
Series control/interface, subtract the total power
units provided by this controller from your
previous total. If you come out even, or you have
power left over, you paging system is complete.
However, if you come out with more VPUs
required than provided, you will need additional
power. The additional power required will be
provided by adding one or more VALCOM power
supplies as listed in Table 2.
