The standard details requirements for a range of alarm systems including central station burglar alarms, police station connected alarms, local alarms, proprietary systems, holdup alarms, and digital alarm communicator system units. It also covers power supplies essential for burglar-alarm equipment operation.
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.
The NFPA 72 "covers the application, installation, location, performance, inspection, testing, and maintenance of fire alarm systems, supervising station alarm systems, public emergency alarm reporting systems, fire warning equipment and emergency communications systems (ECS), and their components."
Residential fire alarm systems are commonplace. Typically, residential fire alarm systems are installed along with security alarm systems. In the United States, a residential fire alarm system is required in buildings where more than 12 smoke detectors are needed. [19] Residential systems generally have fewer parts compared to commercial systems.
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.

Traditional smoke detectors are ionization smoke detectors which create an electric current between two metal plates, which sound an alarm when disrupted by smoke entering the chamber.
Methods are needed to ensure that the alarm system does not drift from its rationalised state. Step 6: Real-time alarm management. More advanced alarm management techniques are often needed to ensure that the alarm system properly supports, rather than hinders, the operator in all operating scenarios.
An alarm monitoring center, central monitoring station (also known as "CMS" or wholesale central station), or alarm receiving center (also known as ARC) [1] is a company that provides services to monitor burglar, fire, and residential alarm systems. The Central Monitoring Station may also provide watchman and supervisory services.
