You are viewing the Autocall fire alarm control panel that operates and automates many manual pull rod fire alarm systems. Autocall made thousands of these panels in the 1950's and 60's. They were very common in public schools and other public institutions. Bells or horns could be wired to the panel along with pull stations/ boxes. You could also tie-in heat detectors and other similar devices. These vintage control panels can still be found today in many older buildings. The code wheel in the middle of the lower panel is 4-4-4-4 cadence march time.
