Possible values: ‘Busy Standard’, or ‘Busy Class’

System default configuration: ‘Busy Class’ on Zone Fired Microphones

‘Busy Standard’ on Paging Microphones

Typically a Fire Microphone (such as the standard SMC02 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 message status of the zone (either one or more of the group of zones controlled by this button). Whereas

Paging Microphones (such as the ‘S’ variant SMC02 units) 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 indicate the emergency 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.

Typically 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

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.

This is the default setting for standard Zoned Fire Microphone SMC02 units.

• ‘Busy Standard’ mode:

The ‘Busy’ LED of a zone select 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 ‘S’ variant Paging Microphone SMC02 units.

Ensure that the SMC02 is configured to the appropriate LED indication mode.
