On April 28, 1852, in Johnson Hall formerly on this site, the first municipal electric fire alarm system using call boxes with automatic signaling to indicate the location of a fire was placed into service. Invented by William Channing and Moses Farmer, this system was highly successful in reducing property loss and deaths due to fire and was subsequently adopted throughout the United States and in Canada.
