A fire alarm box, fire alarm call box, or fire alarm pull box is a device used for notifying the fire department of a fire. Typically installed on street corners, they were the main means of summoning firefighters before the general availability of telephones.
When the box is activated by turning a knob or pulling a hook, a spring-loaded wheel turns, tapping out a pulsed electrical signal corresponding to the box's number. A receiver at fire headquarters annunciates the pulses through flashing lights or tones and the box number is matched to a list of box locations. In modern installations a computer receives and translates the pulses; in unmanned installations in small communities, the box number may be sounded out by a horn or bell audible community-wide. Though still in wide use, many communities have removed them, relying instead on the widespread availability of landline and mobiles. Cache is at N52.40.??? E000 55.???
