A fire suppressing system having at least one suppressant source, at least two control valves in communication with the suppressant source, and at least two distributors, each distributor being in communication with one of the control valves. The control valves are movable between at least three of first, second, third, and fourth positions. Functionally, in the first position, each of the control valves passes suppressant therethrough, but does not pass suppressant to its distributor. In the second position, each of the control valves does not pass suppressant therethrough, but passes suppressant to its distributor. In the third position, each of the control valves passes suppressant therethrough, and passes suppressant to its distributor. In the fourth position, each of the control valves does not pass suppressant therethrough and does not pass suppressant to its distributor. Depending upon the positions of the control valves, the suppressing system directs suppressant from the suppressant source to any one or more of the distributors.

Method and apparatus for distributing fire suppressant

An atomizing nozzle and fixed clean agent fire suppression system. The system stores gas fire suppressant in a liquefied state separate from propellant gas. Upon demand, the propellant charges the gas fire suppressant to provide a piston flow system that pushes the gas fire suppressant in the liquid state through a pipe network to the protected area of a building. The system includes a plurality of atomizing nozzles for atomizing the gas fire suppressant where it more easily vaporizes. Each atomizing nozzle comprises a nozzle body and a deflector body secured together in fixed relation. A conical flow passage is formed between the nozzle body and deflector body. The conical flow passage extends radially outward to a circumferential outlet slot that spreads the liquid clean agent out into a thin liquid conical fan that breaks up into droplets and atomizes quickly.
