NOTE: The intercom used MUST supply a holding  
ground or page control lead to properly operate the  
V-1101A. A page control lead is a lead that supplies  
Ground whenever the intercom is in use, and which is  
Open when the intercom is idle. Contact the  
manufacturer of your intercom if you have questions  
about this lead.  
INSTALLATION  
General  
These instructions cover the installation procedures  
for the Valcom V-1101A and any associated  
equipment. Please consult practices for other  
manufacturer's equipment if any other equipment is  
being used. Refer to Figure 2 for connection block  
pinouts.  
Operation: Press the intercom button and dial the  
number assigned to the V-1101A. You will then be  
connected to the paging speakers. Make  
announcement. The V-1101A will automatically  
disconnect when you hang up.  
The following sections contain step-by-step  
instructions for wiring the Valcom V-1101A one zone  
one-way page adapter. Each instruction is preceded  
by a line. Place a check on the appropriate line as the  
instruction is completed. The instructions also  
include tests along the way to verify connections have  
been made correctly. If these steps are followed  
exactly, installation of your Valcom system will go  
smoothly and quickly. If the results of a test do not  
correspond with what is shown, DO NOT PROCEED  
UNTIL THE PROBLEM HAS BEEN

OPERATION  
General  
The V-1101A contains the required circuitry to allow  
paging access from most types of telephone systems.  
To operate correctly, the V-1101A must receive two  
signals: a ground on the Holding Ground input and  
either a momentary AC signal on the Signal Input  
lead or a momentary or continuous ground on the  
Ground Start lead.  
Once the V-1101A has been activated it will remove  
the background music (if connected) from the  
speakers and allow you to page. The unit will stay  
active until you hang up, at which time the holding  
ground will be removed and the unit will be allowed  
to release.  
The unit may be wired for loop start operation for use  
on PABX's or electronic key systems (Figure 3). In  
this application the unit will supply the –24 Vdc talk  
battery required by the telephone system trunk card.  
The holding ground and start leads required by the  
page unit will be supplied internally in this case.  
TECHNICAL ASSISTANCE  
When trouble is reported, verify the unit is properly  
connected and there are no broken connections  
leading to this unit.  
Connections for access by a 1A2 line button are  
similar to those above, except that the unit is  
cross-connected directly to the button of the  
telephone instead of to a trunk card (Figure 4). A  
spare set of relay contacts is used to switch lamp  
voltage to the phones.  
Assistance in troubleshooting is available from the  
factory. When calling, you should have a VOM and a  
test set and be calling from the job site. Call (540)  
563-2000 and ask for Technical Support, or call  
(540) 767-1555 for Valcom 24-hour Automated  
Support or visit our website at  
When connecting the V-1101A to an intercom  
number (Figure 5) four leads are required from the  
intercom: Tip and Ring to supply audio, a Page  
Control Lead, and a Signal Lead. The Page Control  
Lead must supply a Ground whenever the intercom is  
in use, and must be open when the intercom is idle.  
This lead is used to release the V-1101A at the end of  
a page. The intercom may be wired to use 10 Vac, 18  
Vac, or 105 Vac for signaling. The intercom signal  
must be momentary, i.e., the signal must be present  
for approximately 1 second and then drop off. A  
continuous signal will prevent the V-1101A from  
operating.  
Valcom equipment is not field repairable. Valcom,  
Inc. maintains service facilities in Roanoke, VA.

number, contact person, and the nature of the  
problem.

TROUBLESHOOTING CHART  
Symptom  
Solution  
1. No output at speakers. 1. Check for audio on the Red/Brown pair of the V-1101A while paging.  
(a) If audio is present: Verify proper audio and power wiring to speakers. Try  
connecting a speaker in the equipment room: Connect the Tip and Ring leads  
directly to the Red/Brown pair of the V-1101A and connect the –24 Vdc and  
ground leads to the power supply. Test again.  
(b) If no audio: Refer to Wiring Instructions and complete the power test (step  
7). Correct any problems and test again. If there is still no audio, then return  
to the installation Figure used and verify ALL connections. Use a meter to  
verify the connections from the punchdown block to the amphenol. If there is  
still no audio and you used Figure 5 Intercom Access, connect a bell or  
buzzer to the V-1101A H and SIG leads. Dial the page access number. If the  
bell or buzzer does not ring, then you are either not getting a page control  
from the intercom, or you have connected the wrong half of the signal pair to  
the V-1101A SIG lead.  
2. Music will not cut off  
during a page.  
2. Complete all steps above for “no output at speakers”.
