Configuring a Digital Input (Contact) for Routing
Any digital input may be configured as a contact to trigger a route connecting any desired combination of
audio inputs to any combination of outputs. Audio inputs are typically DVAs, however other type of inputs
such as microphone, background music, and test tone can also be routed.
Therefore a single contact may cause an EVACUATE message to be broadcast in one zone, and
simultaneously cause an ALERT message to be broadcast to some other zones while all remaining zones
are unaffected.
It is possible to configure how the route will be triggered:
•
Not Latched mode
The activation of a contact configure for Not Latched mode initiates a route. When the contact is
released, the route is cleared.
This mode is suitable for routing any type of input.
•
Latched mode
A momentary, or prolonged, activation of a contact configured for Latched mode initiates a route.
A separate contact must be specified to act as a reset contact whose activation clears the route unless
the corresponding trigger is still asserted.
This mode is suitable for routing any type of input.
•
Play Once mode
A momentary, or prolonged, activation of a contact configured for Play Once mode plays the DVA
associated with the route once only. When the DVA has completed its full message cycle, the route is
terminated.
This mode is suitable for triggering and routing DVAs.
The DVA assigned to a button may be configured to cease playing when the route is terminated or reset
(DVA-Part), or play until its end (DVA-Full).
It is also possible to configure whether or not the route associated with a contact should cause a busy
indication on the LEDs associated with microphone zone select buttons. If for instance this routing were used
for background music control, then the busy LEDs would not be lit. If another type of route were being made,
then the busy LEDs would normally be lit.
