5.4 Configuring the Microphone Control Parameters
5.4.1 Microphone Priority
Menu: ConfigurationÆSystemÆRouterÆInputsÆMic/LineÆ<I/P #nn – input name>
ÆFire MicrophoneÆCtrlÆPri
Possible priority levels: 01 to 19 (01 is the highest priority)
System default configuration: Fire or Zoned Fire Microphone on input 1 – ‘01’
Fire or Zoned Fire Microphone on input 2 – ‘02’
Paging Microphone on VAR4/VAR12/VAR20 – ‘07’
Paging Microphone on DAU/VAR8/ACU/VAR8-ACU – ‘11’
The input priority is used to resolve conflicts when two or more inputs try to broadcast to the same output. In
this case the input with the highest priority will be able to broadcast to this particular output, and the others
will not. The priority also determines if the user may be overridden by other users during broadcast to an
output.
Note that when the microphone is connected to an ACU input, the ACU uses the priority to arbitrate the use
of the network audio channels. Each slave unit (DAU or VAR Router) in the network then uses the priority
locally assigned to this ACU input for local arbitration as described above.
If an announcement from a Fire Microphone is overridden by a higher priority Fire Microphone, the lower
priority Fire Microphone will be restored immediately after the higher priority Fire Microphone has completed
the announcement.
Set the priority of the microphone input as required. Consult the system design documentation to find the
correct priority.
Care should be taken in ensuring that Fire Microphones, and Alarm and Emergency DVAs have
a high priority, and non-emergency sources, such as non-emergency DVAs, Paging
Microphones, and music sources, have low priorities. This is to ensure that the emergency
inputs can override normal inputs.
The system default priorities are set to help this by ensuring that by default Fire Microphones
have the highest priorities in the system: priority ‘01’ being assigned to a Fire Microphone
connected to input 1, and priority ‘02’ to a Fire Microphone connected to input 2.
