INPUT CONTACTS
CONNECTION
The unit has 19 input contacts, which can be
configured by means of the P.A. Manager
software.
To activate a contact, this contact must be
grounded.
These inputs are used for:
Local pre-recorded message activation:
When the input contact is activated, a pre-
recorded message is sent from the DVA-
102ETH to one or several zones.
Zone selection: When the input contact is
activated, a destination zone is pre-
selected. When the priority of the AUDIO
INPUT is activated, the signal applied to the
AUDIO INPUT will be sent to this zone.

They are open collector outputs, as shown in the diagram in Figure 11. These
outputs can be used, for example, to activate analog zones, to select zones of an
MC12/24L, to activate the priority of external devices, to light a LED…
