Dictograph 55-0

So, I discovered one error in my overview. The black silence button on the face is for silencing an alarm condition, not a trouble. Sorry for the error. Any other input or corrections is welcome. This is a circa 1962 fire alarm, which is no longer supported of course. This particular system had 42 FG135 fixed temperature heat detectors, and 9 G217 pull stations. Looks like a class A loop, supervised electrically rather than through and EOLR.
