"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.”

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 -24VDC - R/BR
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.
