Table 2 - Valcom Power Supplies

There are several cases when more than one
power supply will be required:
1. When the power required exceed the

maximum output of the power supplies
available: Add additional supplies as
required.

2. In large systems or systems with many horn

speakers: Locate separate power supplies
near groups of speakers. (Refer to Table 6
for guidelines concerning maximum allowable
distances for power runs.)

3. When the paging system is in several

buildings or on several floors of a single
building, locate power supply in each building
or on each floor being paged.

Block Diagram of Multiple Zones of One-Way Paging
From Multiple Telephone System Page Ports

Valcom V-1094A, V-2000A or V-2001A control
units may be used for page port access to Valcom
paging. Each of these units provide one zone of
one-way paging. If more than one page port is
available a V-1094A, V-2000A or V-2001A may be
used on each port for multizone paging. For help
in speaker and power supply selection refer to
Tables 2 and 3, and to the section titled "1A2,
Dedicated Single Line Set, E-Key, or PABX
Paging".

NOTE: Generally, Valcom dial select
multizone page units may not be used on page
port output. (The V-2003A and V-2006A may be
used on certain page ports that have an
associated page port contact closure and
support DTMF signaling).

Station level Paging

The Valcom V-9940 and V-9970 Station level
Page Adapters may be utilized to provide access
to a single or multiple zone paging system via an
incoming central office line, Centrex//Essex line or
PABX station.

This device:
1)   Accepts a ringing phone line or station port.
2)   Answers that line.
3)   Provides line level audio to the paging

system.

For a single zone of paging, Valcom One-way
Amplified Speakers may be directly connected to
the audio output of the station level page adapter.

Electrically, station level page adapters act
like a "self-answering" telephone.

The V-9940 and V-9970 are FCC registered for
direct connection to the public telephone network,
and also carry U.L. 1459 approval. It will ring trip
from 70 to 105 VRMS (20 to 30 hertz) ringing
voltage.

With a single line telephone, the called party
provides disconnect at the end of the
conversation by going "on hook". A station level
page adapter, on the other hand, has no way of
"knowing" when the calling party has finished
speaking. This unit has to sense line conditions in
order to determine when it is time to disconnect.
