Description
Rarely seen in this day and age, but at the time this was state of the art. A fire alarm box is an outdoor device used for notifying a fire department of a fire. Early boxes used the telegraph system and were the main method of calling the fire department to a neighborhood in the days before people had telephones. When the box is triggered, a spring-loaded wheel spins and taps out a signal onto the fire alarm telegraph wire, indicating the box number. The receiver at a fire station then can match the number to the neighborhood.
