Saving a vintage AGRO Fire bell.

The history of the fire alarm bell goes back centuries, evolving from ancient church bells used to warn of disaster to modern mechanical systems that alert the public to fires. Early systems were simple, with bells signaling the start and end of shifts or summoning volunteer firefighters. As technology advanced, the telegraph enabled remote monitoring, leading to the development of more sophisticated mechanical alarms in the 1800s, which ultimately paved the way for the electronic and digital fire alarms common today.
