Viking started in 1880 and they are still in Hastings, Michigan making fire suppression equipment. These old alarms are still on buildings around Kalamazoo. Do they still work?

These bells used to be on the outside of buildings, like this one on the old Fuller Theater and was the only notice to a fire that existed almost 100 years ago. This video gives you an idea of how they sounded.

You can still find them to collect on Ebay. My question still goes unanswered, do they work? Has anyone used one recently?
