@ator @JessTheUnstill huh. This might be an instance where “master” makes sense, it’s not referring to slave and in airplanes, it really is a catch-all. (Are you thinking of “master caution” in a cockpit?)
But in the spirit of doing away with it anyway, “global” or “integral” might do?
@johnelamb @JessTheUnstill I'm thinking of its general use in e.g. annunciator panels, which does apply usually to planes, yes. Reason being that I'm developing a game which has "master alarms" that can be individually silenced.
I don't think global or integral are clear enough - global implies a warning for the whole system, while integral seems unintuitive to me (less clear definition imo)
