The main mission of a fire detection system is to detect the presence of fire as soon as possible and to be able to launch the alarm signals so that the building can be evacuated and the extinguishing teams can be notified. Also to activate the automatic extinguishing mechanisms that the building has, such as sprinklers. A fire detection system is based on complex and constantly evolving technology. Its operation corresponds to the fire detection and extinction plan that must be applied in the building. It can be fully automated or also include mechanisms that are activated manually, such as alarm buttons.
