DVA-3003

3 Channel Digital
Voice Announcer

Technical Practice

June 19, 2001

3 Channel Long Play Digital Announcer

The DVA-3003 is a
professional and cost-effective three channel
digital voice announcer specifically designed for ACD/UCD, hotel-motel wake up, auto
attendant, intercept, night message, information applications and other announcement
functions.

The DVA-3003 will increase call handling capacity by answering on demand or during
the first ring, automatically adjusting the announce cycle to the message length,
disconnecting on C.P.C. and providing instant “rewind” for the next caller.

The DVA-3003 is factory installed with 1 minute of record time per channel and may be
expanded to 4 minutes per channel using the ERAM-60 one minute memory expansion
kits. In applications where a single, longer message is required, the DVA-3003 can

VIKING©

also be configured as a single channel 3 to 12 minute announcer.

Installation

A. 120V AC Operation

The DVA-3003 is provided with a 120VAC U.L. listed adaptor with a 12VDC 500mA output. The DVA-3003 requires a
24 hour unswitched 115VAC outlet. To protect the internal electronics, the installation of a surge protector is
recommended.

B. 48VDC Operation

Connect -48VDC and Earth Ground to the terminal block as shown below. Nominal current draw is less than 100mA.
If a power supply protection fuse is used in series with the -48V supply, a 500mA slow blow fuse is recommended.
The initial start up current can surge as high as 600-700mA.

Programming

A. Standard Ring Trip Interface (Two Wire)

Any ringing C.O./PABX line will be answered, given an announcement and released. The DVA-3003 is then
immediately ready to answer the next incoming call. Set the front panel DIP switches to RING TRIP for each channel
using “Ring Trip” Interface, then momentarily disconnect power. *

B. Continuous Play 4 Wire E & M Interface

Set the front panel DIP switches to E & M for each channel using E & M Interface. Set “E & M protocols” DIP
switches to “A” (DIP switches 5 and 6 off). Invert the START signal (DIP switch 7 on). *Momentarily disconnect the
power. The announcement will be repeated continuously on pins 3 and 4 (600 ohm output).

C. 600 Ohm 4 Wire E & M Protocols

First set the front panel DIP switches to E & M for each channel using E & M Interface, then momentarily disconnect
power.* Four different protocols are now switch selectable for changing E & M timing, plus the ability to invert the
START and/or BUSY signals.

six digit security code (factory set to 8,4,5,4,6,4,). Two beeps should then be heard, confirming the correct
security code was entered. You are now in the remote recording mode. Follow the recording, monitoring, and
programming steps in sections 3 - 5 on page 6.

2. Four Wire E & M Interface Mode

To gain system access call (from a Touch Tone phone) the C.O. line or PABX extension connected to the DVA­3003’s PROGRAMMING PORT. The unit will answer and give two beeps. You are now in the remote recording

mode. Follow the recording, monitoring, and programing steps on page 7.

3. Recording

5. Ring Delay (Ring Trip Interface)

The ring delay is factory set to “Immediate Answer” (unit answers in less than one full ring). The ring delay can be
programmed from “Immediate Answer” (0) to 9 rings. Example: If ring delay is set to 1, unit will answer after one
full ring cycle.
Enter (0-9), #, 1, 1 to program ring delay for channel 1.
Enter (0-9), #, 1, 2 to program ring delay for channel 2.
Enter (0-9), #, 1, 3 to program ring delay for channel 3.
Enter (0-9), #, 1, 4 to program ring delay for programming port.

6. E & M Timing

The Beginning Of Message and End Of Message pulse width is factory set to 600msec. This may be programmed
from 100msec. (enter 1) to 900msec. (enter 9) for each channel.
Enter (1-9), #, 2, 1 to program E & M timing for channel 1.
Enter (1-9), #, 2, 2 to program E & M timing for channel 2.
Enter (1-9), #, 2, 3 to program E & M timing for channel 3.

7. Transfer Phone Numbers

The transfer phone numbers are disabled from the factory. When a transfer phone number is programmed, the
DVA-3003 will perform a hook switch flash transfer (dialing the programmed phone number after the channel
announcement has been played.

Enter up to 16 digits (1-9), #, 0, 3 to program a transfer phone number for channel 3.

8. Message Repeat

Each channel has the ability to repeat the announcement up to 99 times before disconnecting or transferring an
answered call. The factory default for the message repeat count is set to 01.
Enter 2 digits (01-99), #, 3, 1 to set the message repeat count for channel 1.
Enter 2 digits (01-99), #, 3, 2 to set the message repeat count for channel 2.
Enter 2 digits (01-99), #, 3, 3 to set the message repeat count for channel 3.

9. Changing Your Security Code

It is recommended that you change the security code from the “845464” factory setting to your own personal 6 digit
number. To change the security code, enter your 6 digits _ _ _ _ _ _ plus #,4,7.

Note: The security code can not include a ✱ or #.

Note: To disable the hook switch flash transfer for a channel, leave the 16 digit

Operation

After the DVA-3003’s announcements have been recorded and monitored, place the unit into the ANNOUNCE mode.
Use DIP switches 1, 2, and 3 on the front panel to select Ring Trip Interface or E & M mode for channels 1, 2 and 3.
These switches are only read when first powered up. Momentarily disconnect power after changing the DIP switches.

A. Ring Trip Interface

A standard C.O. line or PABX extension should be connected to the CO/PABX LINE input jack for that channel. The
DVA-3003 will answer after the programmed ring delay, play the announcement for the message repeat count,

perform a hook switch flash transfer if a number is programmed, or disconnect. The BUSY screw terminals provide a
contact closure during the announcement. If the caller hangs up during the announcement, the DVA-3003 will detect
the C.P.C. signal (if present) and disconnect that line. It is now immediately ready for the next incoming call.

B. 4 Wire E & M Interface:

The 600 OHM E & M jack provides a 600 ohm “Dry” output. Refer to the protocol timing specifications on page 3 and
the PBX table on pages 4 and 5 for the control lead connections.

Single Channel Mode

The DVA-3003 may be configured as a single channel announcer with up to 12 minutes announcement time. In this mode
of operation, channels 2 and 3 are disabled, and channel 1 utilizes the combined digital announcement memory time of all
three channels. A stock DVA-3003 has a total of 3 minutes of single channel announcement memory. Viking model

ERAM-60 memory expansion chips can be installed to extend the announcement memory to a total of 12 minutes. Each
ERAM-60 chip will add one minute of announcement memory. To enable the single channel mode, set front panel
SINGLE CHANNEL DIP switch to ON, then momentarily disconnect power.
