The DVA-1003A will increase call processing capacity by answering on demand or
during the first ring, automatically adjusting the announce cycle to the message length,
and providing instant ”rewind” for the next announcement.
The DVA-1003A is a cost-effective, professional digital voice announcer specifically
designed for ACD/UCD, hotel-motel wake-up, auto attendant, intercept, night message
and other announcement functions.

1. 120V AC Operation
Installation
A. Standard Ring Trip 2 Wire (J1-A, J2-A, J3-A)
Use J2 only. Set protocol switch to “A.” Any ringing C.O. line or analog PABX/KSU station will be answered, given
a message, released and immediately be available for the next ring.
B. Continuous Play (J1-B, J2-B, J3-B)
Use J3 only. Set protocol switch to “A.” Connect Yto BK. The announcement will be repeated continuously on
R&G 660 Ohm output.
C. 600 Ohm 4 Wire E & M Protocols (J1-B, J2-B, J3-B)

The DVA-1003A is provided with a U.L. or C.S.A. approved power supply with 12V DC output. The DVA-1003A
requires a 24 hour unswitched AC outlet. To protect the micro-processor and provide maximum efficiency, it is
recommended that a surge protector is installed/
2. 48V DC Operation
Connect the terminal strip as shown on the rear panel drawing. Current is less than 200mA. If adding an
external fuse to the 48 volt power supply to the DVA-1003A, a slow blow fuse (500mA) should be used because
of the 600-700mA surge current when first connecting the 48 volts to the ground and -48 volt screw terminals.
C. Battery Back-Up
The DVA-1003A is equipped with a rechargeable NICAD battery that will maintain the memory for up to 1 hour
during a power failure. The DVA-1003A must be powered for 48 hours to fully charge the battery. For applications
requiring full operation during power failures, a power back-up system is recommended (Fax Back Document 505).
