Canada

Type of device made and used in Canada to alert firefighters in a fire department, of the presence of a fire in the neighbourhood where the alarm box is situated.

Fonction

To rapidly transmit an alarm of fire to a firefighting force.

Technique

The first practical fire alarm system was developed in Boston in1852, by Dr. William Channing and Moses Farmer. It worked on the principal of telegraphy: a signal was sent long distances over wires, by electric transmission. "In the first boxes, a notched code wheel was turned by a crank handle in the front of the box. Then, it evolved with a spring-driven, clockwork-type mechanism which drove the code wheel when activated by a lever." Boxes were put on a pedestal or telephone pole at a street corner. Early boxes were locked with keys which were given to the citizens and policemen who had the responsibility of pulling the lever in the event of a fire. In 1875 a model was made that did not need a key. In 1922, the quick-action door was put on the market. This model has a quick-action door and is made of a die-cast silicon-aluminium alloy called Herculite. There are two main components that make up this kind of fire alarm system: the telegraph mechanism, located on a street corner, and the alarm apparatus (gongs and indicators), located inside a fire department's Headquarters. One-way communication between the telegraph and alarm system was made possible by linking both boxes with aerial and/or ground-level wires. Central station equipment would receive the signal, revealing the location of the fire, and would proceed to notify the firehouse nearest to the fire by transmitting another signal to their alarm box.
