Abstract: A fire suppression system comprising at least one or at least two wall-mounted spray head units capable of aiming and shooting fire suppressant liquid into a fire is disclosed.

Abstract: A system is disclosed which is operable to supply fire suppressant material (6) and marker (7) to at least one spray head unit (2) for producing spray having a droplet size less than 1000 ?m. The system may be operable in two modes. The system may be operable in fire suppressing mode to supply fire suppressant material to the one or more spray heads and in marker deployment mode to supply fire suppressant material and marker to the one or more spray heads. In fire suppressing mode, the system supplies the fire suppressant material for a long period of time, for example, a few tens of minutes. In marker deployment mode the system supplies the fire suppressant material and marker to the spray heads for a short period of time, for example, a few tens of seconds.
