A method in the fire protection of an area, in which in the area are arranged several fire extinguishing spraying heads (1) which, when activated, spray extinguishing medium in the area, and between which adjacent spraying heads there is a spacing (S1, S2). The spraying heads (1) are arranged in the area (A1, A2) by defining a water flux density of extinguishing medium required for protecting the area being protected and by defining feed pressure (p1, p2) of extinguishing medium for the spraying heads (1) of a certain area or section of an area, whereby the spacing (S1, S2) of adjacent spraying heads depends on the magnitude of the feed pressure (p1, p2) and a K value of the spraying head so that the water flux density of extinguishing medium intended for spraying is substantially constant. The invention also relates to an apparatus.
A method in the fire protection of an area, in which in the area are arranged several fire extinguishing spraying heads (1) which, when activated, spray extinguishing medium to the area, and between which adjacent spraying heads there is a spacing (S1, S2), characterised in that the spraying heads (1) are arranged in the area (A1, A2) by defining a water flux density of extinguishing medium required for protecting the area being protected and by defining feed pressure (p1, p2) of extinguishing medium for the spraying heads (1) of a certain area or section of an area, whereby the spacing (S1, S2) of adjacent spraying heads depends on the magnitude of the feed pressure (p1, p2) and a K value of the spraying head so that the water flux density of extinguishing medium intended for spraying is substantially constant.
A fire-extinguishing apparatus, which comprises spraying heads (1) arranged in an area being protected and means for conveying extinguishing medium to the spraying heads, characterised in that adjacent spraying heads are arranged in relation to each other at a spacing (S1, S2) which is dependent on feed pressure (p1, p2) of extinguishing means in the activated mode of the system when a water flux density of extinguishing medium intended for spraying is substantially constant.
