“WARNING: To reduce the risk of fire or
electric shock, do not expose this equipment
to rain or moisture.”
“WARNING: Shock Hazard - Do Not Open.”
“AVIS: Risque de Choc Electrique ne pas
Ouvrir.”
“PELIGRO: Corriente Electrica - No Abra.”
“CAUTION: To reduce the risk of fire replace
only with same type 1A, 125V fuse. 1A, 125V
may be replaced by a 0.5A, 250V provided
voltage selector is set for 230V.”
“DANGER: Afin de réduire le risque de feu,
remplacez le fusible par le même type de
fusible à 1A, 125V. On peut utiliser un
fusible à 0.5A, 250V pourvu que le sélecteur
ďalimentation soit fixé sur 230V. Ne pas
ouvrir.”
“VORSICHT: Zur verringerung von
feuergefahr die sicherung nur mit derselben
type 1A, 125V ersetzen. Statt 1A, 125V Kann
0.5A, 250V Benutzt werden, vorausgesetzt,
die spannung ist auf 230V eingestellt. Nicht

•Use a cord set consisting of a minimum 18
AWG cord and grounding type attachment
plug rated a minimum of 15A, 250V. The
cord set should have the appropriate safety
approvals for the country in which the
equipment will be installed and should be
marked HAR.
•The socket outlet shall be installed near the
equipment and shall be easily accessible.
NOTE: The AC line cord of the VPB-260 and
the AC line cord of the V-2001A should be
plugged into the same AC circuit.
Environment
Temperature: 0 to +40° C
Humidity: 0 to 85% non-precipitating
INSTALLATION
NOTE: The telephone system referred to in
this manual is the customer premise
equipment such as an electronic key system,
a PABX or a dedicated single line
telephone(s). The V-2001A is not intended
for direct or indirect connection to the public
telephone network or to PABX analog station
ports. When used with a customer premise
telephone system such as a key system
or PABX system, these units are interfaced
to the system via a fully protected page port
or system central office port, which is a fully
protected interface device. Also, the host
system must be configured to disallow
central office trunk conferencing in order to
prevent indirect connection to the public
network.

Mounting
The V-2001A was designed for wall or table
mounting. Secure unit to wall studs or a suitable
brace away from heat sources or strong
magnetic fields (Motors, fans, power supplies,
etc.) with the control and terminal strip
accessible. Four wood screws are included for
mounting.
Power Connections
NOTE: This equipment must be installed
near an AC power outlet due to the power
cord being used as a disconnect device.
•The V-2001A is provided with a NEMA 5-15
cord set for North American use.
•Connect cord set to unit via IEC 320 female
connector located on one end of cord set to
IEC 320 male appliance coupler located on
the V-2001A.
•For 115VAC use, verify fuse rating of 1 Amp
and voltage selector switch displays 115V.
•For 230VAC use, verify fuse rating of 0.5
Amp and voltage selector switch displays
230V.
After all required connections
have been made, plug the cord
set into appropriate AC wall
outlet.
CONNECTIONS
Refer to Figure 1.
Electronic Key or PABX Access
When using the V-2001A with an electronic key
system, C. O. line position or PABX trunk port,
the battery feed switch (SW1) must be ON.
Pre-Page Alert Tone Option
The Pre-Page Alert Tone may be used when
accessing the unit from an electronic key
system, C. O. Line position, PABX Trunk Port or
a Page Port with a contact closure. Page Ports
must provide a contact closure output. To
enable the pre-page alert tone feature, place a
jumper on the yellow and black leads (outer pair
of RJ-11) of J3. (See Figure 1).
NOTE: The pre-page alert tone operates on
the primary paging input only.
Operation: Press line key (Electronic key
system) or dial trunk access code (PABX) to
connect to the paging speakers. Make
announcement. The V-2001A automatically
disconnects from page.
Page Port Access
When accessing the V-2001A from a telephone
system page port, the battery feed switch (SW1)
must be OFF.
Operation: Follow the telephone system
manufacturer's instructions for access to
external paging. Make announcement. The
V-2001A automatically disconnects from page.
The V-2001A voice switching circuit is activated
when the person making the page begins to
speak. When the page is completed or the
person stops speaking for more than two
seconds, the paging circuit turns off. Other
functions of the unit remain the same.
Background Music
Background music may be connected to the
V-2001A when using either access method.
Background music mutes on the "page + music"
outputs when a page is made.
Connect the output of a low level music source
to the screw terminals marked "Music" on the
input terminal strip on the V-2001A. Adjust
music volume control on the V-2001A to the
desired level.
Night Ring and Single Tones
Night ringing (Electronic warble tone) over
paging is activated by a common audible
contact closure or 90VAC ring voltage.
A single tone (Time clock) over paging is
provided when the V-2001A is connected to a
contact closure.
Tone Options
SW4 enables or disables single and warble
tones on all page outputs. SW2 enables or
disables single tones and warble tones on the
page without music output only.

Page Override
Page override requires the use of a vacant
C. O. line position, vacant loop start trunk port or
dedicated single line telephone set for access
(In addition to the page port, vacant C. O. line
position or vacant loop start trunk port used for
primary access of the V-2001A).
Using a modular telephone cord, connect the
V-2001A RJ11 jack labeled "Tip and Ring OVR"
to the phone system vacant C. O. line position or
vacant loop start trunk port.
Operation:Press line key (Electronic key
system) or dial trunk access code (PABX) for
page override access to connect to paging
speakers (Overriding page in progress). Make
announcement. The V-2001A disconnects
when phone is hung up, re-establishing the
overridden page announcement.
Connection of One-way Amplified
Speakers
The Valcom V-2001A provides external power of
20 power units (1 Amp -24VDC) to operate one-
way amplified speakers. Additional power
supplies are required for a quantity of speakers
using over 20 power units. When using
additional power supplies, make certain:
1) The -24VDC outputs are not connected
to each other.
2) Each speaker is connected to only one
power source.
Volume Adjustments
The page volume is set by the speakers. Adjust
speakers 1/3 to 1/2 volume initially, test and
reset if necessary for correct page volume.
There are two volume controls for individual
adjustment of:
•Background music
•Tones (Warble/single tone)
Clockwise adjustment increases volume,
counter clockwise adjustment decreases
volume.
TECHNICAL ASSISTANCE
When trouble is reported, verify power is being
supplied to the unit and there are no broken
connections. Check voltages for proper polarity
to the one-way amplified speakers. Table 1
identifies symptoms of some possible
problems with solutions. If a spare unit is
available, substitute a spare unit for the
suspected defective unit.
Assistance in troubleshooting is available from
the factory. When calling, you should have a
telephone test set, several clip leads, a VOM
available and call from the job site. Call

TABLE 1: TROUBLESHOOTING CHART
SYMPTOMS PROBABLE CAUSES AND SOLUTIONS
1. No output to speakers A. Check for the presence of audio on the page outputs of the V-2001A during a
page using a test set. Refer to installation section for connection information.
B. Check AC line fuse on V-2001A.
2. No music output A. Using a test set, check for music on the music input terminals.
B. Check that speakers are connected to “page + music” outputs.
3. No warble tone output A. If a contact closure is provided by the telephone system, use an Ohm meter to
check the continuity of the contact closure when the contact closure accesses
the unit.
B. If ringing is used, with an AC Volt meter, check for the presence of ring voltage
when a call is ringing into the telephone system.
C. Check selector switches (SW2 and SW4).
4. No single tone output A. Using an Ohm meter, check the contact closure on the device that is to operate
the single tone.
B. Check selector switches (SW2 and SW4).
NOTE: The contact closure operation of the V-2001A can be tested with a length of wire connected between
the two terminals of either the UNA/warble or clock/steady tone inputs.
