Ann Arbor, MI Restore shop Rare alarms

This system I believe is not in service anymore but the system contains 1 Dual Projector Benjamin Electric Horn and a handful of National Time and Signal 511s and 1 Federal Signal Vibratone.

wow you have got a lot of rare stuff in your area

Yeah, not to mention a lot of stuff by National Time! (though you do live in Michigan where they’re based)

I definitely find it interesting how that dual-projector horn is not only the only one in the system but that it’s suspended from the ceiling by the conduit that the wires to it run through!

Unusual how a Honeywell system seemingly controls the horns (mainly because the horns are probably AC & the panel puts out DC).

The only pull station in the whole building is a BG-12 and they have L-Series in the building.
