Abstract
The invention relates to an installation for extinguishing fire, the installation comprising a number of spray heads (,), a pipe system (,) for leading extinguishing medium to the spray heads, which spray heads comprise a holder body having an inlet for incoming extinguishing medium and at least one nozzle. In order to be able to use the installation in conditions in which it can be strongly exposed to dirt and impurities and in order that it will not be activated on account of the spray heads of the installation being exposed to impacts or heat not coming from the seat of the fire, the installation is characterized in that the spray heads (,) comprise a cover, which is positioned by means of a locking device in a protective position in front of said nozzle when the installation is in an inactive mode and which is, upon activation of the installation, arranged to be displaced to a free position, in which the cover is out of the way of said nozzle, the cover being arranged to be displaced to the free position when a fluid exerts a force against the locking device so that this opens.
