A fire extinguishing system is a permanently operational technical system that extinguishes a fire with an extinguishing agent .
Stationary fire extinguishing systems
Stationary (stationary) fire extinguishing systems consist of a pipeline system with suitable output devices (examples: sprinklers, extinguishing nozzles) through which the extinguishing agent is discharged in the event of an emergency. They will either automatically indirectly by fire detection and extinguishing control systems or directly by mechanical fire detection and release elements (Examples: glass bulb fusible ) triggered manually or. The systems should automatically extinguish a fire or contain it until the fire brigade arrives to extinguish it.
Controls for stationary fire extinguishing systems
Controls for stationary extinguishing systems serve to protect people from the fire hazards of machines and systems. In addition, they also protect against the dangers of the extinguishing process itself, which can arise from the escape of oxygen-displacing extinguishing gases when staying in the interior of an accessible machine or when opening the workspace doors. The safety functions of the controls are carried out in accordance with DIN EN ISO 13849-1. A test principle of the Institute for Occupational Safety and Health of the German Social Accident Insurance (IFA) describes the testing and certification of the controls of stationary extinguishing systems.

- Nitrogen extinguishing systems
- Inert gas extinguishing systems with gas mixtures ( Inergen , Argonite)
- Chemical extinguishing systems ( Halon , FM-200, Novec 1230 )
- other types of extinguishing systems
Active fire prevention systems act like nitrogen fire extinguishing systems; However, they supply the space to be protected with nitrogen as a preventive measure, so that a fire cannot even start.
Mobile fire extinguishing systems
Mobile fire extinguishing systems are available as permanently installed in fire fighting vehicles, as swap trailers or as containers for fire fighting vehicles, which are used on the carrier vehicle depending on the application (example: mobile carbon dioxide fire extinguishing systems for companies in the chemical industry ).
