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").

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

Valcom equipment is not field repairable. Valcom,  
Inc. maintains service facilities in Roanoke, VA.  
Should repairs be necessary, attach a tag to the unit  
clearly stating your company name, address, phone  
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.

Ringback Tone: Adjust this control to  
produce the desired level of ringback tone at  
the door plate speaker when the door plate  
push-button is pressed.
