Plug the V-2901 AC Line Cord into
appropriate 115VAC receptacle.
Battery Back-Up
A Valcom VPB-260 Battery Back-up may be added
to the system to provide power in case of power
failure. Figure 6 shows the appropriate connections.
The VPB-260 should be allowed to charge for
approximately 9 hours before operating the V-2901.
Adjust volume (See "Volume
Adjustments").

Telephone
OPERATION
General
__1.
Refer to Table 1 for dip switch settings to
program single digit door unlock code.
When the door plate button is pressed, interrupted
ring voltage from the V-2901 is applied to a C.O. line
position of the telephone system and a ringback tone
is sent to the door plate speaker for the duration that
the call button is pressed. When the line is answered
the ringing is removed and the handsfree amplifier is
connected.
__2.
Figure 3 shows the V-2901 contact
arrangement available for electric strike
plate operation.
Before connecting an electric lock to the V-2901,
consult the manufacturers instructions for the proper
connecting arrangement.
If the door is equipped with an electric strike plate, a
preset number can be dialed from the tone dial
telephone, operating a relay for 2.2 seconds. The
relay provides make/break contacts that may be used
to operate the strike plate. A single pole push-button
switch connected to the V-2901 can also be used to
manually operate the door unlock relay.
Remote Door Unlock with
Push-button
__1.
Connect single pole push-button to V-2901
screw terminals marked Remote Control
Unlock.
The V-2901 provides make/break contacts that follow
the ringing cycle. These contacts can be used to
operate external signaling devices.
Remote Signaling
__1.
The V-2901 contains an auxiliary set of
make/break contacts. These contacts follow
the ringing cycle after the door plate
push-button has been pressed. They can be
used to operate a remote signaling device;
i.e., bell, buzzer, or light. Figure 4 shows a
typical connection using these contacts.
NOTE: Operation is the same when used with all
telephone systems.
TECHNICAL ASSISTANCE
Table 2 identifies symptoms of some possible
problems with solutions.
Volume Adjustments
There are three volume controls on the V-2901. Two
are used to adjust the page level to the door and the
handsfree reply. The third control adjusts the
ringback tone to the door plate speaker. See Figure 5
for location.
Assistance in troubleshooting is available from the
factory. When calling, you should have a VOM and a
test set available and be calling from the job site.
Call (540) 427-3900 and ask for Technical Support,
or call (540) 427-6000 Valcom 24-hour Automated
Support or visit our website at

number, contact person, and the nature of the
problem. Send the unit to:
IMPORTANT: This is the most critical
adjustment. Set the volume at the lowest
practical level. Setting this control too high
will increase background noise without
giving greater talkback volume.
