5.3 Configuring Microphone Control Parameters

Menu: Configuration Æ System Æ Router Æ Inputs Æ Mic/Line Æ < I/P # nn – MIC/LINE nn >

Æ < Zoned Fire Microphone or Paging Microphone > Æ Ctrl Æ Pri

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 ACU – ‘11’

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 reinstated. 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.

Menu: Configuration Æ System Æ Router Æ Inputs Æ Mic/Line Æ < I/P # nn – MIC/LINE nn >

Æ < Zoned Fire Microphone or Paging Microphone > Æ Ctrl Æ Pri Æ Class

Possible values: ‘High Priority Emergency, ‘Low Priority Emergency’, or ‘Non Emergency’

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 “ 5.3.6 Busy and Select Indication LEDs Mode

(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.
