ABSTRACT:
The invention provides systems and methods adaptable to all gaseous agents including Helium to suppress fire in at least one enclosed space. Suppressants are delivered by a dedicated subsystem connected to cargo compartments or to engine nacelles, or by an integrated system connected to cargo compartments and engine nacelles. For example, at least a first reservoir stores fire suppressant composition for knocking down a fire in an enclosed space. Piping delivers the composition from the at least first reservoir to the enclosed space. A pressure sensor senses pressure of the composition in the piping, and a controllable purging device permits air to exit the enclosed space responsive to sensed pressure in the piping of the composition.
