"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
öffnen.”
“PELIGRO: Para reducir el peligro de
incendio remplazarlo unicamente con un
fusible del mismo tipo 1A, 125V. El fusible
de 1A, 125V podra ser remplazado por uno
de 0.5A, 250V si el selector de voltaje esta
puesto en 230V. No abres.”

Environment
Temperature: 0 to 40 Degrees 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 set(s). The V-
2001A-E 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-E 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-E may be used with one of the
following:
-NEMA 5-15 cordset for North American use;
-CEE/7 cordset for Continental European use;
-BS1363 cordset for United Kingdom use.
-Connect cordset to unit via IEC 320 female connector
located on one end of the cordset to IEC 320 male
appliance coupler located on the V-2001A-E.
-For 115VAC use, verify fuse rating of 1 amp and
voltage selector switch displays 115 V.
-For 230VAC use, verify fuse rating of .5 amp and
voltage selector switch displays 230 V.
-After all required connections have been made, plug
the cordset into appropriate AC wall outlet.

Refer to Figure 1.
Electronic Key or PABX Access
When using the V-2001A-E with an electronic key
system C. O. line position or PABX trunk port, the
battery feed switch (SW1) must be ON.
Operation: Press line key (electronic key
system) or dial trunk access code (PABX) to connect
to the paging speakers. Make announcement. The V-
2001A-E automatically disconnects from page.
Page Port Access
When accessing the V-2001A-E 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-E
automatically disconnects from page.
The V-2001A-E 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-E 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-E. Adjust music volume
control on the V-2001A-E 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.

4 947218
A single tone (time clock) over paging is provided
when the V-2001A-E is connected to a contact
closure.
Operation: SW4 enables or disables single and
warble tones on the page with music output. 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-E).
Using a modular telephone cord, connect the V-
2001A-E 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-E disconnects when phone is hung up,
re-establishing the overridden page announcement.
Connection of One-Way Amplified
Speakers
The Valcom V-2001A-E 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 - 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 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 and a VOM available, and
be calling from the job site. Call [phone] and
ask for Technical Support, or call [phone] for
Valcom 24-hour Automated Support or visit our
website at http://www.valcom.com.
Should repairs be necessary, contact your local
distributor for instructions.

TROUBLESHOOTING CHART
SYMPTOM
PROBABLE CAUSE AND SOLUTION
1. No output to speakers.
A. Check for the presence of audio on the page outputs of the V-2001A-E during a page
using a test set. Refer to installation section for connection information.
B. Check AC line fuse on V-2001A-E.
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 they are operated when a call is ringing into the
telephone system.
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-E can be tested with a length of wire connected between the two terminals
of either the UNA/warble or clock/steady tone inputs.
