How can I tell if there is an active alarm in an alarm group?

How can I tell if there is an active alarm in an alarm group?

Hi,
In my project I have my alarms grouped into 9 alarm groups.
I need to have a button change colour if there is currently an active alarm in a specific alarm group.
For this I need either a BOOL for active alarm in this group yes/no or a value for number of active alarms in the group so I can check if it is > 0.
How can I do this please?
