GC3 and severe weather warning

So today we had 3 tornado warnings, and the panel alarmed us!

however, we have the panel volume turned down, is it possible to turn the severe warning beeping up by itself?

The message alerts on the GC3 are governed by the “System Annunciation” volume setting I believe.

System Settings - master code - Sounds - System Annunciation.

does that also control the door open announcements?

No, voice and chime is a separate setting
