I feel like there was a “Fire alarms in odd places” at some point on the forum, but I think it’s long gone now. This isn’t exactly a building, but this topic will do 
.
So anyways, here’s an odd system: A Simplex 4010 addressable panel installed aboard the SS William A. Irvin, a U.S. Steel Iron Ore Ship. There are TrueAlert signals installed throughout.
Note the angle of the pull station. Due to the curvature of the the hull, the pull stations and horns on exterior walls on the upper decks are pitched downward, and pulls & horns mounted on lower decks and in the cargo hold are pitched severely upward. The devices in the engine room, crew’s quarters, and bridge are all mounted relatively normal.
