Configuring the Microphone Control Parameters

5.3.1

Microphone Priority

Menu: Configuration System Router Inputs Mic/Line <I/P #nn – MIC/LINE nn>
Possible priority levels:
System default configuration: Fire or Zoned Fire Microphone on input 1 – '01'
The priority will determine if the user may be overridden by other users during paging in certain zones.
If the override source is removed during the original announcement, then the overridden zones will not be re-
instated. This is to minimise the broadcast of potentially ambiguous or annoying message fragments.
Note that the action is different if an announcement from a Fire Microphone is overridden by a higher priority
Fire Microphone, in this case the lower priority Fire Microphone will be restored immediately that the higher
priority Fire Microphone has completed the announcement.
Note that when the microphone is connected to an ACU (Audio Control Unit), the ACU uses the priority to
arbitrate the use of the network channels.
Consult the system design documentation to find the correct priority, and then program the SMC02 priority.
5.3.2

Microphone Class

Menu: Configuration System Router Inputs Mic/Line <I/P #nn – MIC/LINE nn>
Possible values:
System default configuration: 'Non Emergency'
•
On VAR4/VAR12/VAR20:
The emergency class is used to control the VAR Router's Remote Fault Output when configured for
'Emergency DVA Active Indicator' as follows:
−
The output is activated if an emergency audio input, e.g. ALERT or EVACUATE DVAs, is routed to
an output.
−
The output is not activated if all outputs are routed to non-emergency audio inputs, e.g. Paging
Microphone or music, or are not routed.
Changes to this setting may result in an inappropriate indication of the VAR Router's Remote Fault
Output when this is configured for 'Emergency DVA Active Indicator'.
•
In an Intellevac Network:
The emergency class is also used by the ACU (Audio Control Unit) and Fire Microphones connected to
an ACU to indicate the emergency message status of the zone group configured for a Zone Select button
via its 'Busy' and 'Select' LEDs, as described in Section
(ACU only)" (page 34).
In an Intellevac Network, the Mic/Line input class should be set to 'Non Emergency' regardless of
microphone type in order to provide the appropriate indication of the emergency message status on the
ACU's front panel.
