2.2.2 Routing Digital Voice Messages (DVA Routing Buttons)

The ‘DVA Routing’ button function enables simple control of a single broadcast route, or complex broadcasts to be set up. For instance when a button is pressed a route can be made that connects any desired combination of audio inputs to any combination of outputs. Audio inputs are typically DVAs, however other types of inputs such as microphone and background music can also be routed.

An example of this is a button programmed to cause an EVACUATE message to be broadcast in one zone, and simultaneously cause an ALERT message to be broadcast to adjacent zones, while all remaining zones are unaffected. Another example would be a set of ‘DVA Routing’ buttons which controls background music broadcast to selected zones in the system.

• ‘DVA Routing’ buttons are only supported on microphones connected to VAR Router’s

Mic/Line inputs 1 or 2.

• ‘DVA Routing’ buttons are not fully operational when the standard SMC02 units are operating in All Call Only failsafe override mode.

If the red BUSY LED against any zone button is illuminated is illuminated it indicates that an announcement is already in progress on the system. The operator can however still go ahead with the broadcast if it is not important for the broadcast to definitely be heard in the affected zone or zones. It is possible that the other audio source could be of lower priority, and therefore be overridden by the SMC02 microphone, however it is not good practice to routinely override other announcements in general day to day usage.

Note that the above is the standard LED indication mode, however on standard SMC02 units connected to an Audio Control Unit (ACU) the

BUSY and SELECT LEDs can be configured to indicate the status of the emergency message in the zone (or group of zones) configured for a DVA

Routing button as follows:
