Possible values: ‘Busy Standard’, or ‘Busy Class’
System default configuration: ‘Busy Class’ on Zoned Fire Microphones
‘Busy Standard’ on Fire, Paging, and Single Button Microphones
Normally a Zoned Fire Microphone (such as the standard SMC01 units) connected to an ACU (Audio Control
Unit) is configured to drive the ‘Busy’ and ‘Select’ LEDs of a zone select button to indicate the emergency
DVA message status of the zone (either one or more of the group of zones controlled by this button).
Whereas Fire Microphones (such as the EAP01 and FMS1) are configured to drive these LEDs in the
standard mode, i.e., to indicate the zone ‘Busy’ and ‘Select’ conditions in similar fashion to when the
microphone is connected to a VAR Router. These modes are detailed as follows.
• ‘Busy Class’ mode:
The ‘Busy’ and ‘Select’ LEDs of a zone select button indicate the emergency DVA message status of
the zone (either one or more of the group of zones controlled by this button) configured for this zone
select button according to the emergency class of the currently routed audio sources.
The ‘Busy’ and ‘Select’ LEDs are driven as follows:
− The ‘Busy’ LED is turned ON continuously if any output in the group configured for the button is
connected to an input that has been configured as a High Priority Emergency source.
The ‘Select’ LED is turned ON continuously.
− The ‘Busy’ LED flashes ON and OFF repeatedly if any output in the group configured for the button
is connected to an input that has been configured as a Low Priority Emergency source, and no
output in the group is connected to a High Priority Emergency source.
The ‘Select’ LED is turned ON continuously.
− The ‘Busy’ LED is turned OFF if any output in the group configured for the button is connected to an
input that has been configured as a Non Emergency Priority source, and no output in the group is
connected to a High or Low Priority Emergency source.
The ‘Select’ LED is turned ON continuously.
− The ‘Busy’ LED is turned OFF if all outputs in the group configured for the button are not connected
to any input.
The ‘Select’ LED is turned OFF.
Normally the emergency class is set-up as follows:
− EVACUATE DVA: High Priority Emergency
− ALERT DVA: Low Priority Emergency
− Other audio sources (microphone, auxiliary DVAs, music): Non Emergency
Therefore the ACU (or the Zoned Fire Microphone) will show all evacuation zones with a steady ‘Busy’
LED, all alert zones with a flashing ‘Busy’ LED, and all other zones without the ‘Busy’ LED lit.
This is the default setting for Zoned Fire Microphones.
• ‘Busy Standard’ mode:
The ‘Busy’ LED of a zone select button is turned ON continuously to indicate that the zone (either one
or more of the group of zones controlled by this button) configured for this zone select button is already
in use by another input, and the ‘Select’ LED indicates the zone selection state.
The input emergency class has no effect on the LED indication.
This is the default setting for Fire Microphones (such as the FMS1), Single Button Microphones, and
Paging Microphones.
The ‘Select’ LED is not present on the EAP01. Therefore ensure that the EAP01 is configured to the ‘Busy
Standard’ mode in order that the ‘Busy’ LED (if connected) is driven to indicate the zone status.
