Viking DVA-2WA Product Manual page 5

4. Multiple Units with I.O. (Input/Output) Communication
When installing multiple DVA-2WA's in displays that are close enough together to cause audible
interference, the I.O. communication will allow only one DVA-2WA to announce at a time. The
last unit to be triggered will announce its message, disabling any current messages played
from any previously triggered DVA-2WA.
Connect speakers and remote momentary switches to the DVA-2WAs as shown in Installation
Step 1
sections 1, 2 or 3.
Connect the I.O. Com connections as shown below to prevent two announcers from playing at
Step 2
one time.
A remote "stop" switch can be connected to the I.O Connections A & B. A momentary closure
Step 3
will stop message.
