  • Patent number: 10052509
    Abstract: The present invention relates to a system as well as a method for extinguishing fire in an enclosed room (6) in which the enclosed room (6) is flooded with extinguishing gas at least until an extinguishing gas concentration capable of providing an extinguishing effect (a) is set in the flood zone. In order to achieve the realizing of a maximum extinguishing gas concentration (b) as quickly as possible without the flooding of the room (6) thereby posing a danger to people, it is inventively provided for the flooding of the enclosed room (6) to be divided into a pre-flooding phase and a main flooding phase subsequent thereto. The pre-flooding phase corresponds to an interval of time between the time (t1) the alarming starts to warn people of impending danger and a predefined time (t2). The main flooding phase corresponds to an interval of time between the predefined time (t2) and the time (t4) at which a maximum extinguishing gas concentration (b) is reached.
