“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

General

Press the line key (Electronic Key System), dial
the trunk access code (PABX) or dial the page
port access code to access the
V-2003A/V-2003AHF; with dedicated single line
sets - simple go off hook. The
V-2003A/V-2003AHF will return dial tone (If so
optioned). Dial desired zone code: 1, 2, 3, or 5,
6, 7 for individual zones (1 through 3
respectively). Dial 4 or 8 for the all call of all
zones. Ringback tone (If so optioned) will be
heard in the telephone receiver. Make
announcement and hang up. The unit will
automatically disconnect from page. Ringback
tone and repeated alert tones, when optioned,
provide an alert tone to the talkback zones on a
V-2003AHF. The repeated alert tones will
broadcast every 15 seconds when the zone is
active in the handsfree mode.

Background Music

A line level amplified background music source
may be connected to the control unit. The
background music will cut off only in the zone
being paged if the zone is programmed for
background music.

Night Ring and Single Tones

Two methods of night ringing (Electronic Warble
Tone) over the paging system is available.
___1. UNA Closure: Activated by a Common

Audible, Dry Contact Closure

___2. UNA Ringing: Activated by 90VAC

+/- 20% (20/30Hz) ring voltage

Clock Tone

A single tone over page is provided when a Dry
Contact Closure is connected to the Clock
Closure Input Terminals (i.e. Time Clock).

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 the
single tone and warble tone are both selected
on or both selected off).

Page Port Access

When used with page port access, the Page
Control Unit may only be used with a 600 Ohm
page port equipped with contact closure that
will pass DTMF for zone selection. Also, the
page port must be capable of passing

bi-directional audio for talkback operation (V­2003AHF).

INSTALLATION

Precautionary Designations

equipment such as an electronic key system,
a PABX or a dedicated single line
telephone(s). The V-2003A/V-2003AHF is not
intended for direct or indirect connection to
the public telephone network or any
telephone line providing dial tone. 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.

Electronic Key, 1A2, PABX or Single Line
Access

When using the V-2003A/V-2003AHF with an
electronic key system, 1A2 key system, PABX,
or dedicated single line telephones, the following

equipment is required:

(1) 1 - V-2003A/V-2003AHF Three Zone

Paging Unit

(2) 1 - C. O. Line Circuit (Electronic Key

System), 1A2 line position equipped
with 400 type card, Loop or Ground
Start Trunk Circuit (PABX), a page
port with contact closure and DTMF
signaling or one or more dedicated
single line telephone(s) (Not a station
port or extension number)

(3) Valcom Amplified Speaker Assemblies

(Quantity and style determined by
specific installation; Valcom 45 Ohm
Talkback Speakers may also be used
with the V-2003AHF)

CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

CAUTION: To reduce the risk of electric shock,

Refer servicing to qualified service personnel.

NOTE: The telephone system referred to in
this manual is the customer premise

Do not remove cover.

No user serviceable parts inside.

This symbol indicates that dangerous
voltage constituting a risk of electric
shock is present within this unit.

This symbol indicates that there are
important operating and maintenance
instructions in the literature accompanying
this unit.

Mounting

The V-2003A/V-2003AHF was designed for wall
or table mounting. The intended mounting
orientation will render the enclosure lid text
legible (See Figure 4). Secure the 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 (A plywood backboard
2' square and at least1/2" thick attached to wall
studs would be considered a suitable brace).
Four #10 x 3/4" cross-tip wood screws are
included for mounting. Fasten two screws on
the mounting surface allowing them to protrude
1/8" to 1/4". Place the chassis of the control unit
onto the screwheads at the mounting slots.
Position the remaining screws and fasten
through the remaining mounting slots. Tighten
screws.
