Yea, I kinda got myself there in a roundabout way in the end.
In any case, if that's the environment, then it reminds me of our solutions for broadcast studio alarms. There was a combined master tone alarm in the engineering control room, and a set of annunciators for each station, with three levels of severity for each. You'd hear the tone, snap your head around to look at the board, and quickly be able to tell what you were dealing with and where the priority problems were.
Likewise, in the hallway leading up to the studios, there were colored flashing lights above each studio door that also displayed the alarm level for that studio. Those were completely silent, for obvious reasons, but their flashing pattern got your attention anyways. They were arranged vertically according to severity so even if you were color blind you could understand them at a distance.
Then inside the studios there were more detailed annunciators that would actually display which part of the air chain monitoring was causing the global alarm signal. These were also silent, but did not flash, and had a clock that would pause when the first error became displayed.
