Abstract

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.
