Early Wheelock Mini Horn?

I’m guessing they’d still sound like a GX-90/typical smoke detector sounder.

I’m still curious about the “slow whoops”. And those weird-sounding signals in a UAlbany dorm that had the octogonal grilles and 7002T-type strobe, but made a weird sort of tone that sounded like a mechanically-generated Hi/Lo set to some type of code.
