I know, so I’m only going to describe my school’s fire alarms ONCE, so everyone’d better listen up…
The Field House building has all SAE horn/strobes…
…as well as Simplex 4251 T-bar pulls.
(They’ve been labeled for each zone.)
The Fine Arts building also has several of those new HORN/strobes, but unlike most of the other 1978 buildings, it still has some of the old fire alarm NAs intact! They are the widely-discussed-on-this-forum Simplex 4051 horns on 4050-80 retrofit light plates.
They’re being replaced with the new SAE horn/strobes because they aren’t up to code, like in the Humanities and Liberal Arts buildings.
I also forgot to add that many of the Simplex T-bars have Stopper II covers over them, without the sounders.
