Abstract: A water mist head (1) for a fire fighting system, the water mist head (1) being mounted at least 15 cm from a ceiling (5) or a wall (10). The water mist head (1) comprises a nozzle part (2) comprising a plurality of nozzles (3), and a plate (6) comprising an at least substantially plane part (7). The plate (6) is arranged between the nozzle part (2) and the ceiling (5) or wall (10), preferably adjacent to the nozzle part (2). The plate (6) prevents the sprays (4) produced by the nozzles (3) from pulling air along. Thereby it is prevented that the sprays (4) ‘collapse’, and a more diverted spray patter is obtained, the water mist head (1) thereby being capable of covering a larger area. Thus, the plate (6) creates an effect similar to that of a ceiling or wall arranged adjacent to or near the nozzle part (2).
