UNIVERSAL DOOR ANSWERING SYSTEM
INTRODUCTION
The V-2901A, Universal Door Answering System,
when used with Valcom Doorplate Speakers,
provides voice paging with handsfree reply to a door
from any telephone location. The V-2901A initiates
ring-in on the telephone system and sends a
confirmation tone to the door speaker. The individual
at the phone responding to the signal will determine if
access should be allowed. Pressing a programmed
code on the telephone dialpad or pressing the remote
button will unlock the door to allow admission. The
V-2901A also provides an alarm control output to
alert an alarm system of an unauthorized entry.
These instructions contain the specifications and
information necessary to install, operate and maintain
the Universal Door Answering System.

* A single line telephone cannot be connected to
both the V-2901A and an incoming central office
line.
** It is recommended that one talkback speaker
be used. Use of more than one talkback speaker
may result in damage to the V-2901A. Up to 40
one-way amplified speakers may be connected to
the V-2901A speaker output.
DESIGN
The V-2901A, Universal Door Answering System,
was designed to provide voice paging with handsfree
reply to a door speaker from a telephone location.
The V- -2901A initiates ring in on the telephone
system and sends a confirmation tone to the door
when a button is pressed at the door (Valcom
doorplate speakers are normally used in this
application). The individual at the phone responding
to the signal can converse with the person at the door
and determine if access should be allowed. If the
door is equipped with an electric strikeplate, the
person at the phone can enter a programmed code on
the telephone dialpad or press a remote button to
unlock the door to allow admission. A call to the
door may also be initiated from the telephone system.
The V-2901A provides an alarm control output for
unauthorized entry. When the door lock relay is
activated and the door remains open longer than the
programmed period of time, a ground potential will
appear on pin 3 of the V-2901A (unauthorized door
opening) that can be used to signal a customer
provided alarm, auto dialer, etc. Also, if the phone is
on hook, the phone will begin ringing in a single burst
pattern. If the phone is off hook, it will receive a
momentary warble tone. After hang-up, if the door is
not closed, the alarm condition will continue.
When indication arrives that a door is open while
door station is inactive, such as a break-in, the system
waits the programmed period of time (entry delay
time) for a confirmation of entry indicating the
opening as legitimate. When this does not arrive in
the programmed time frame or if it arrives and the
door is not closed at the end of the programmed time
period, an alarm will sound in the same manner as
described above.
The V-2901A also provides a background music
input and is designed to automatically mute music
during a page. If background music is to be installed,
a low level music source such as the Valcom V-2952
FM Tuner will be required.
Applications for the V-2901A includes a doorway,
gateway, window or secure room - just to name a few.
INSTALLATION
Cabling
A 25 pair cable with a female amphenol connector
should be run from the V-2901A to a 66 block. The
cables should be terminated on the connecting block
in standard color code. Refer to Figure 2 - Block
Connections for the pinout locations.
Mounting
The V-2901A is designed to be wall or shelf
mounted. When wall mounting the V-2901A, secure
the unit to wall studs or a suitable brace, away from
heat sources or strong magnetic fields (motors, fans,
power supplies, etc.) with controls and connectors
accessible. (A plywood backboard two feet square
and at least 1/2 inch thick attached to wall studs
would be considered a suitable brace).
Four #10 x 3/4 inch flat-head wood screws are
included for mounting. Fasten two screws on the
mounting surface, allowing them to protrude 1/8 inch
to 1/4 inch. Place the chassis of the V-2901A onto
the screwheads at the mounting slots. Position the
remaining screws and fasten through the remaining
mounting slots. Tighten screws.
Connections
Mount a 66 block on the backboard near the
V-2901A Universal Door Answering System and
label the block per Figure 2.
Move slide switch SW2 on the V-2901A to the
appropriate location, Loop or Ground Start, (see
Figure 3) depending on how the V-2901A is
accessed.
If a modular cord is used for Tip and Ring
connections, start at step ONE. For 66 block
connections start at step TWO.
___ 1. Connect one end of the modular cord to the
V-2901A RJ11 and the other end to the
appropriate line position of the phone
system. Go to step 3.
___ 2. Connect Tip of the key system line position,
loop or ground start trunk, to Pin 26 (W/BL)
and Ring to Pin 1 (BL/W).
___ 3. Connect Tip of a 45 Ohm talkback speaker
to pin 32 (R/O) and Ring to pin 7 (O/R).
