A fire alarm box, fire alarm call box, or fire alarm pull box is a device used for notifying a fire department of a fire or a fire alarm activation. 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. Fire Alarm Call Boxes are still widely used in many cities and towns.
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. [1] A receiver at fire headquarters announces the alarm through flashing lights or tones, or via a pen recorder, 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. Some call boxes can be wired to a Fire alarm control panel or annunciator to send a signal to a fire station or dispatch center when a fire alarm is activated in a particular building. Telegraph systems do not give any information about why an alarm was triggered, only the box number which tells firefighters where to respond.
The first telegraph fire alarm system was developed by William Francis Channing and Moses G. Farmer in Boston, Massachusetts in 1852. [3] Two years later they applied for a patent for their "Electromagnetic Fire Alarm Telegraph for Cities." In 1855, John Gamewell of South Carolina purchased regional rights to market the fire alarm telegraph, later obtaining the patents and full rights to the system in 1859.
John F. Kennard bought the patents from the government after they were seized after the Civil War, returned them to Gamewell, and formed a partnership, Kennard and Co., in 1867 to manufacture the alarm systems. The Gamewell Fire Alarm Telegraph Co. was later formed in 1879. Gamewell systems were installed in 250 cities by 1886 and 500 cities in 1890. By 1910, Gamewell had gained a 95% market share. [4]
Though fire alarm boxes remain in use, many communities have removed them, relying instead on the widespread availability of landline and cellular telephones. [5] Cities like San Francisco still rely heavily on fire alarm boxes for redundancy in case of emergency. [6] Some municipalities still maintain their fire alarm boxes near schools and other sensitive locations.
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. [2] [3]
Despite lack of popular awareness that the boxes still work, a fire box was used to report a fire in Boston in December 2018 during a 9-1-1 outage. [7]
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. Some of these included an "ear-shattering" wail that would cause discomfort to someone activating the box, while others would handcuff a detachable part of the device to the person triggering the alarm, so that responding police and fire officials (who possessed the key for release) could more easily identify and contact the individual responsible for the activated alarm. [8] [9]
A telephone is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user. The term is derived from Greek: τῆλε and φωνή, together meaning distant voice. A common short form of the term is phone, which came into use early in the telephone's history. Nowadays, phones are almost always in the form of smartphones or mobile phones, due to technological convergence.
A police box is a public telephone kiosk or callbox for the use of members of the police, or for members of the public to contact the police. It was used in some countries, most widely in the United Kingdom throughout the 20th century from the early 1920s. Unlike an ordinary callbox, its telephone was located behind a hinged door so it could be used from the outside by anyone, and the interior of the box was, in effect, a miniature police station for use by police officers to read and fill in reports, take meal breaks and even temporarily hold detainees until the arrival of transport.
A fire hydrant, fireplug, or firecock (archaic) is a connection point by which firefighters can tap into a water supply. It is a component of active fire protection. Underground fire hydrants have been used in Europe and Asia since at least the 18th century. Above-ground pillar-type hydrants are a 19th-century invention.
The New York City Fire Department, officially the Fire Department of the City of New York (FDNY) is the full-service fire department of New York City, serving all five boroughs. The FDNY is responsible for fire suppression and fire prevention, and is a major provider of EMS services in New York City. Beyond fire suppression and EMS, the FDNY is responsible for a broad range of services, including technical rescue, CBRN defense, and structural collapse response and analysis. The FDNY is equipped with a wide variety of general-purpose and specialized Vehicles,Tools and Equipment to serve its varied missions.
A call box or callbox is a box containing a special-purpose direct line telephone or other telecommunications device which has been used by various industries and institutions as a way for employees or clients at a remote location to contact a central dispatch office.
The Great Boston Fire of 1872 was Boston's largest fire, and still ranks as one of the most costly fire-related property losses in American history. The conflagration began at 7:20 p.m. on Saturday, November 9, 1872, in the basement of a commercial warehouse at 83–87 Summer Street. The fire was finally contained 12 hours later, after it had consumed about 65 acres (26 ha) of Boston's downtown, 776 buildings and much of the financial district, and caused $73.5 million in damage. The destruction to the buildings was valued at $13.5 million and the personal property loss was valued at $60 million. In the end, at least 30 people died, including 12 firefighters.
Firefighting is a profession aimed at controlling and extinguishing fire. A person who engages in firefighting is known as a firefighter or fireman. Firefighters typically undergo a high degree of technical training. This involves structural firefighting and wildland firefighting. Specialized training includes aircraft firefighting, shipboard firefighting, aerial firefighting, maritime firefighting, and proximity firefighting.
A PASS device, also known as a Distress Signal Unit (DSU) or ADSU, is a personal safety device used primarily by firefighters entering a hazardous or Immediately Dangerous to Life and Health (IDLH) environment such as a burning building. The PASS device sounds a loud (95 decibel) audible alert to notify others in the area that the firefighter is in distress. On a fireground, the sound of an activated PASS device indicates a true emergency and results in an immediate response to rescue the firefighter(s) in distress. In the United States, the National Fire Protection Association sets standards for PASS devices in NFPA 1982.
Firefighting jargon includes a diverse lexicon of both common and idiosyncratic terms. One problem that exists in trying to create a list such as this is that much of the terminology used by a particular department is specifically defined in their particular standing operating procedures, such that two departments may have completely different terms for the same thing. For example, depending on whom one asks, a safety team may be referred to as a standby, a RIT or RIG or RIC, or a FAST. Furthermore, a department may change a definition within its SOP, such that one year it may be RIT, and the next RIG or RIC.

Manual fire alarm activation is the process of triggering a fire alarm through a call point, pull station, or other device. This usually causes the alarm to sound the evacuation signal for the relevant building or zone. Manual fire alarm activation requires human intervention, as distinct from automatic fire alarm activation such as that provided through the use of heat detectors and smoke detectors. It is, however, possible for call points/pull stations to be used in conjunction with automatic detection as part of the overall fire detection and alarm system. Systems in completed buildings tend to be wired in and include a control panel. Wireless activators are common during construction.
Edwin Holmes was an American businessman who is credited with inventing, commercializing the electromagnetic burglar alarm and with establishing the first burglar alarm networks.
The diaphone is a noisemaking device best known for its use as a foghorn: It can produce deep, powerful tones, able to carry a long distance. Although they have fallen out of favor, diaphones were also used at some fire stations and in other situations where a loud, audible signal was required.
A fire alarm system is a building system designed to detect, alert occupants, and alert emergency forces of the presence of fire, smoke, carbon monoxide, or other fire-related emergencies. Fire alarm systems are required in most commercial buildings. They may include smoke detectors, heat detectors, and manual fire alarm activation devices. All components of a fire alarm system are connected to a fire alarm control panel. Fire alarm control panels are usually found in an electrical or panel room. Fire alarm systems generally use visual and audio signalization to warn the occupants of the building. Some fire alarm systems may also disable elevators, which are unsafe to use during a fire under most circumstances.
Traffic signal preemption is a system that allows an operator to override the normal operation of traffic lights. The most common use of these systems manipulates traffic signals in the path of an emergency vehicle, halting conflicting traffic and allowing the emergency vehicle right-of-way, thereby reducing response times and enhancing traffic safety. Signal preemption can also be used on tram, light-rail and bus rapid transit systems, to allow public transportation priority access through intersections, and by railroad systems at crossings to prevent collisions.
The Boston Fire Department provides fire services and first responder emergency medical services to the city of Boston, Massachusetts. It also responds to such incidents as motor vehicle accidents, hazardous material spills, utility mishaps, floods, explosions, and construction accidents among others.
The Tulsa Fire Alarm Building is a historic Art Deco building at 1010 East Eighth Street in Tulsa, Oklahoma. It was built in 1931 and served as the central reporting station for the Tulsa Fire Department. Fires were reported from alarm boxes spread around town to this building and the firemen in this building would alert the fire station closest to the fire. At the time of its construction, this system was the best available alarm system. The building is just east of the Inner Dispersal Loop in Tulsa's Pearl District.
Federal Signal Modulators are electronic warning devices produced by Federal Signal Corporation that are used to alert the public about tornadoes, severe weather, earthquakes, fires, lahars, tsunamis, or any other disaster. They are identified mostly by their distinctive stacked "flying saucer" design. The Modulator II is sold based on the more compact chassis of the siren compared to the original Modulators.

An emergency communication system (ECS) is any system that is organized for the primary purpose of supporting one-way and two-way communication of emergency information between both individuals and groups of individuals. These systems are commonly designed to convey information over multiple types of devices, from signal lights to text messaging to live, streaming video, forming a unified communication system intended to optimize communications during emergencies. Contrary to emergency notification systems, which generally deliver emergency information in one direction, emergency communication systems are typically capable of both initiating and receiving information between multiple parties. These systems are often made up of both input devices, sensors, and output/communication devices. Therefore, the origination of information can occur from a variety of sources and locations, from which the system will disseminate that information to one or more target audiences.
