Vintage Ademco 10” Fire Clapper Bell Burglar Alarm Box Working
This alarm system box was mounted on my house. It dates from 1950's to 1960’s. I removed the rust and repainted it with metal primer. It is in working condition. I do not have the transformer for it, but I ran it at about 50 VAC with a variable transformer. The big 10” bell is cast aluminum and it is very LOUD. The box measures 15”H x 11”W x 4”D. The all steel box has an interior panel for protection from the weather.
