IBM 4250 Pull Station

It was cool to make this vid. I went up to Wal-Mart this afternoon and bought popsickle sticks. When I got home, I took the glass out of the station and replaced it w/ a popsickle stick. This is a vid of me testing it, and as you can see, it was quite successful!

BTW, I currently have this hooked up to my 4001, so be ready for a new system vid to come out shortly.

P.S., Happy New Year!

My old junior high used these pull stations, along with round-horned IBM 4030-2 horns sounding a 4-4 code. I was always afraid that broken glass would stab my palm if I had to smash one of those.

My ES had these along with bells that did the 4-4 code. There were two bell types installed, one 8" and one 6". Presumably the 8" was only for the fire alarm and the 6" was only for class bells but when I was there the 6" bell was used for both the class bells (vibrating mode) and the fire alarm (single-stroke).

can a simlex t handle pullstation and fire light bg12 be used for 120vac?

[weatherdan882002]

The Simplex probably can (non-addressable version at the least), IDK about the BG-12...

This is the same one at my Jr Hi School and I'm glad the Principal allow me to pull a fire drill and I did the same way by striking with my hand or used the key to open it..

[weatherdan882002]

My ES had these pulls as well. They always did a drill by opening the pull. That building's system was ENTIRELY IBM. It had bells, not horns, and the coding candice was 4-4 (very commonly found w/ ancient systems).

Wow; I have never seen an IBM fire alarm system in person; but I have seen a few IBM clock/bell systems at old school buildings (often run by a more modern Simplex master time panel). Usually for alarms they would just use Edwards or Gamewell for some reason instead of IBM's own alarm line.

Nice. I remember these in the old schools. You might be able to use old microscope slides as glass for tests. They're thin and they break easily.

[WheelockAlarms]

The BG-12 can take 20 volts AC or DC And any of the old simplex tbars that have all caps on the bottom can take 120VAC.

thats sweet

pretty cool. i saw on ur website the back of the pull. you can remove that tarnish with some Tarn-X :)

(oh, and by the way, this is my new Youtube user name, my old was thekorean999) add me!

My Jr Hi had a steady buzzer and we had to shut it off at circuit breaker box or reset the station plus it was turn off on weekend because someone always set the alarm off
