DVA Routing/Other Input Routing Button

•
DVA Routing is only available for Paging or Zoned Fire Microphones that are connected to
Router's Mic/Line inputs 1 or 2.
•
Although described as 'DVA Routing' this function can route any input or selection of inputs
at once, so it can be used to route other non-DVA sources such as background music.
The DVA Routing button function is complex routing, i.e. when the button is pressed a route is made that
connects any desired combination of audio inputs to any combination of outputs. Audio inputs are typically
DVAs, however other type of inputs such as microphone and background music can also be routed.
Therefore a single button 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 first press of a DVA Routing button initiates a route, and a second press terminates it.
This mode is suitable for routing any type of input.
•
Latched mode
This mode needs a reset button. Pressing a DVA Routing button initiates a route; and pressing the
associated reset button terminates it.
This mode is suitable for routing any type of input.
•
Play Once mode
Pressing a DVA Routing button 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 DVA Routing button 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.
