Abstract
Fire alarm systems that report either on the premises being served or to parties remote from the original premise are direct descendants of the first viable commercial telegraph in developed in 1837 by Samuel Morse. In 1844 the first commercial telegraph line was constructed between Washington DC and Baltimore. The telegraph was the “internet” of its day, allowing text to travel from city to city on wires at the speed of light. Limitations were only the speed at which they could be coded and decoded.
