Fire alarm call box

Typically installed on street corners or on the outside of commercial buildings in urban areas, they were the main means of summoning firefighters before the general availability of telephones.

The first telegraph fire alarm system was developed by William Francis Channing and Moses G. Farmer in Boston, Massachusetts in 1852.

[4] Though fire alarm boxes remain in use,[5] many communities have removed them, relying instead on the widespread availability of landline and cellular telephones.

The simplicity of telegraph alarm boxes and their associated networks means that they are able to operate under conditions (such as a lengthy or widespread power outage, a natural disaster, or any emergency causing many people to attempt to contact others simultaneously) which may disrupt or disable other communication systems such as landline phones, cellular phones, and emergency services' radio systems.

[8] In the later years of their use and proliferation, some fire boxes were designed with special devices and other functions in place in an attempt to curb the nuisance of false alarms.
