Method for controlling stationary fire-extinguishing systems

Abstract

A method and a fire-alarm system controls stationary fire-extinguishing systems. The fire-alarm devices of the fire-alarm system are equipped with one or more detectors. If at least one pre-adjustable alarm threshold of a fire identification characteristic is reached, the fire-extinguishing device is activated and the fire detectors are selectively switched to a higher stage of sensitivity. The detectors to be switched are locally selected depending on the actual development of the fire in terms of space. The dynamic adaptation of the sensitivity of the detectors to the development of a fire permits analyzing the development of the fire through the generated smoke, water vapor or extinguishing-water mist, and to influence the fire-extinction process in a targeted manner. The fire-extinction process and the development of the fire in terms of time can be effectively adapted in this manner, which contributes to a reduction of the amount of fire-extinguishing used and of the damage caused by the fire-extinguishing agent to persons and valuable materials.
