"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

OPERATION
DO NOT OPERATE UNIT WITH COVER
REMOVED!
Press the line key button (key system) or dial the
appropriate loop or earth call trunk or page port
access code (PABX) to access the control unit.
Dial desired zone code: 1, 2, 3 or 5, 6, 7 for
individual zones (1, 2 and 3 respectively); 4 or 8 for
the all call. Ringback tone (if so optioned) will be
heard in the telephone. Make announcement and
hang up. Page automatically disconnects and
background music (if programmed) returns.
(Ringback tone, when optioned, provides an alert
tone to the talkback zones on a V-2003AHF-E).
Background Music
Background music may be connected to the control
unit. Background music will mute in the zone
accessed for the duration of the page.
Warble and Single Tones
Warble tone is available over the P.A. system when
a common audible contact closure or 90VAC ring
voltage is supplied by the telephone system.
A single tone is provided over the P.A. when the unit
is activated by an additional contact closure.
The single tone and warble tone may be dip switch
selected on a per zone basis. (One dip switch is
supplied per zone for tones, so single tone and
warble tone are both selected on or both selected
off).

NOTE: The telephone system referred to in this
manual is the customer premise equipment such
as a key system or PABX. The V-2003A-E/
V-2003AHF-E cannot be connected directly to the
public telephone network (a central office line).
All connections must be made prior to plugging
the unit to AC power.
Mounting
The V-2003A-E/V-2003AHF-E was designed for wall
or table mounting. Secure the unit to wall studs or
suitable brace away from heat sources or strong
magnetic fields (motors, fans, power supplies, etc.)
with control and terminal strip accessible. Four wood
screws are included for mounting.
NOTE: All controls and terminations are
accessed by removing the right side panel.
Switch Selectable Options
Loop or earth call access, are switch selectable on
the V-2003A-E/V-2003AHF-E. SW1 selects the
loop/ earth call option for system tip and ring. SW5
selects the loop/earth call option for override tip and
ring. (See Figure 3 for location). A 12-position dip
switch is provided for programming capabilities.
Figure 3 indicates the function of each dip switch
(i.e., the feature it activates).
NOTE: For one-way paging on a V-2003A-E, the
dipswitch for the talkback feature on a one-way
zone must be set to "Off" (no zone x talkback).
The V-2003A-E/V-2003AHF-E requires a power
down reset in order to implement dipswitch
changes. (Unplug AC power from the V-2003A-E/
V-2003AHF-E for a minimum of 30 seconds then
reconnect to effect a dipswitch change).
earth strap must be used to connect GND of the
unit to an appropriate telephone system GND
(see Figure 2).
If a modular cord is used for Tip and Ring
connections, connect (J1) RJ-11 A/Tip and B/Ring to
the appropriate loop exchange port of the phone
system.
For punch down block A/Tip and B/Ring connections,
connect Tip of the telephone system or loop or earth
call trunk to the Tip (W/BL) pin and Ring to the
(BL/W) of the KRONE block.
Connection of One-Way Amplified
Speakers
Using twisted pair telephone wire, connect:
Zone 1 Speaker A/Tip, B/Ring - R/BL, BL/R
Zone 1 Speaker -24VDC - R/O
Zone 1 Speaker GND - O/R
Zone 2 Speaker A/Tip, B/Ring - R/G, G/R

Zone 2 Speaker GND - BR/R
Zone 3 Speaker A/Tip, B/Ring - R/S, S/R
Zone 3 Speaker -24VDC - BK/BL
Zone 3 Speaker GND - BL/BK
NOTE: The V-2003A-E provides external power
of 1 Amp of -24VDC to operate amplified speaker
assemblies. Additional power supplies are
required if more than one Amp is needed.
Each speaker should be connected to only one
power source.

Connection of Talkback Speakers
(V-2003AHF-E Only)
Using twisted pair telephone wire, connect:
Zone 1 Speakers A/Tip, B/Ring - BK/G, G/BK
Zone 2 Speakers A/Tip, B/Ring - BK/BR, BR/BK
Zone 3 Speakers A/Tip, B/Ring - BK/S, S/BK
NOTE: No more than two (2) 45 Ohm speakers
should be connected to any talkback zone.
Do not use 8 Ohm speakers.
Page Port Access
When used with page port access, the V-2003A-E/
V-2003AHF-E may only be used with a 600 Ohm
page port that will pass MF tones for zone
selection and that is equipped with a separate
"page enable" contact closure.
Additionally, the
page port must be capable of passing bi-directional
audio for talkback operation.
Connect telephone system dry contact closure to
O/W and W/O of connection block (see Figure 2).
Power Connections
NOTE: This equipment must be installed near an
AC power outlet due to the power cord being
used as a disconnect device.
Telephone System
Page Port
The V-2003A-E/V-2003AHF-E may be used with one
of the following:
• NEMA 5-15 cord set for North American use
• CEE/7 cord set for Continental European use
• BS1363 cord set for United Kingdom use
NOTE: Refer to Figure 4 for the voltage selector
switch and fuse location. Make certain the
voltage selector switch is placed at the
appropriate rating and that the proper rated fuse
is installed.
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-2003A-E/V-2003AHF-E.
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

V-2003A-E Volume Adjustments
There are two volume controls on the unit for
individual adjustment of:
• Background music
• Tones (warble/single tone)
Clockwise adjustment increases volume, counter
clockwise decreases volume. During initial set up,
adjust individual speaker volume controls for page
first, then, adjust volume on page unit to the desired
level for music and tones.
Connections for the V-2003AHF-E
The V-2003AHF-E is programmable on a per zone
basis for one-way or talkback communication. A
single talkback zone may have both one-way and
talkback speakers. One-way amplified speakers
may be connected to the handsfree output of a zone
programmed for talkback to augment the page
output on that zone.
(NOTE: Only talkback speakers are able to
receive reply).
V-2003AHF-E Volume Adjustments
There are five additional volume controls on the
V-2003AHF-E to control the volume of the handsfree
talkback outputs. They are:
• All Call (adjusts volume of page during all call on
handsfree outputs).
• Speaker to Phone (adjusts response volume
from the speaker; should be turned as low as
possible).
• Phone to Speaker (adjusts volume of a page
from phone)
• Background Music (adjusts background music
on handsfree outputs).
• Tones (adjusts the volume of single and warble
tones on handsfree outputs).
Refer to Figure 4 for location of these controls.
NOTE: One-Way Speakers may be connected to
low level outputs on the V-2003AHF-E.
Optional Connections
A. Background Music Connections:
Connect the low level (-10 to -18dBm, 8 to 600
Ohms) output of music source to (W/G) and (G/W)
terminals of the cross connect block. Adjust music
volume (page overrides music).
NOTE: Failure to use a low level music source
could cause music crosstalk on zones not
receiving music.
B. Time Clock Closure (Single Tone)
Connections:
Time clock contact closure - (V/G), (G/V)
Time clock signaling will override page.
C. UNA Closure (Warble Tone) Connections:
Telephone System Night Answer (Contact Closure)(V/BR), (BR/V).
This tone will override music but is overridden by a
page.
D. UNA Ringing (Warble Tone) Connections:
90VAC Night Answer Ringing- (V/S), (S/V)
These connections will activate a night ring tone.
E. Override Connections:
Telephone System Page Override - (W/S),(S/W)
Page override can be activated by a vacant loop
exchange port, loop start or earth call trunk or
dedicated single line phone.
NOTE: Make certain SW1 is in correct position
for loop or earth call mode of operation.
