here's another thing i thought the school fire alarms should sound like, Chimes, and yes these are the types of alarms hospitals use to do drills.
Something like that would be good. In fact, fire stations (at least in Los Angeles), have alarms which are coded tones in the pleasant range; similar to telephone touch tones. Not too loud, but plenty audible by anyone but the 100% hearing-impaired. And there could be a light-based alarm which is not a strobe. Simply having the room lights go from bright to dim, once or twice, accompanied by a something like a red light above the exit doors.
