And finally, the devices that started it all for me.
Simplex 4903-9101 w/ 2901-9838/9846 and
Standard Electric Time MAJ-6 6" bell
I got both of these devices out of the old school in my hometown.
The SET bell could’ve been part of the 1959 addition’s fire alarm system. Either that, or SET 4-350s or Simplex 4040s/41s. I’m not too sure, unfortunately…
The Simplex horn-strobe was probably installed around the early 90s, as the school had a Simplex 4020 FACP.
This 2099-9754 isn’t from the school, but was one of a few different types of pull stations in the building. (A BG-12, some newer dual-action stations, and an Edwards 270-SPO in the '53 wing.)
I got this one new-in-box, but I put the box in storage for now.
