DESIGN
General
The Valcom V-1101A One-Zone One-way Page
Adapter is designed to provide access to paging from
a standard PABX loop trunk port, an electronic key
system or 1A2 key system C. O. line button, or a 1A2
key system intercom number. In some cases, access
is also possible from a PABX or electronic key
system page port.
REMEMBER: All Valcom paging systems are made
up of three basic components: a page control unit,
speakers, and a power supply.
When one-way amplified speaker assemblies are
specified in this manual, consult your Valcom catalog
for the styles available. Once the style and quantity
of speakers is determined, select the appropriate
power supply after referring to the Valcom One-way
Paging manual or the Valcom catalog.
In addition to the parts listed in each of the following
sections, you will need a 66B type punch down block
and a 25-pair cable with a female amphenol
connector. These may be purchased from Valcom as a
unit with the cable and block already connected and
installed on a mounting frame (part # VM-101).
