Antique Fire Alarm Box marked "ADT" & "AERO Automatic Fire". This appears to have been a annunciator box.

It is cast iron construction with the front door being some kind of alloy. It measures 15 inches high x 10 inches wide x 3 1/2 inches deep.

The locking mechanism is a screw type with a 3/16 " key shaft. It has a neat dome top and is the first one I have seen like this.

Do not have the key but this should be the same a old clock wind up type.
