Page Override
A page override feature is available on the V-2001. It
requires the use of a vacant C. O. line position or
vacant loop start trunk port in addition to the page
port, vacant C. O. Line position or vacant loop start
trunk port used for primary access of the V -2001.

V-2001 RJ11 jack labeled "Tip and Ring OVR" and the
other end to the vacant C. O. line position or vacant
loop start trunk port on the customer premise
equipment to be used for page override.
OPERATION
General
When the V-2001 is connected to a C. O. line position
or a loop start trunk port, Tip and Ring battery feed is
provided with the BF switch in the "ON" position.
The voice switching circuit is turned on when the
person making the page begins to speak. Background
music, if connected, will be turned off on the two
outputs marked "page + music" and the persons
voice will be present on all three paging outputs. The
voice switching circuit remains on as long as the
person is speaking. When the page is completed or
the person stops speaking for more than 3 seconds,
the paging circuit is turned off and background music
is restored to the two "page + music" outputs.
The page override feature requires the use of a vacant
C. O. line position or vacant loop start trunk port in
addition to the page port, vacant C. O. line position or
vacant loop start trunk port used for primary access
of the V-2001.
The page override feature is accessed by pressing the
appropriate line key (electronic key system) or by
dialing the appropriate trunk access code (PABX).
Connection to the paging speakers will be immediate
(overriding any page in progress). The V -2001 will
automatically disconnect when the phone is hung up,
re-establishing any overridden page announcement.
A warble tone or a single tone over page can be
provided by the V-2001. A contact closure or 90VAC
ring signal is used to activate the warble tone. The
single tone is activated by a contact closure and
follows the contact operation.
Battery backup for the V-2001 is available through use
of a standard 3-prong polarized MOLEX connector.
The V-2001 is equipped with this connector to allow
the main unit and a limited number of speakers to
work with a fused output (3 amp) battery backup
supply (Valcom VPB-260 or equivalent) in case of AC
power failure.
