A system for extinguishing and suppressing a fire in an enclosed space includes a Halon storage container and a nitrogen generator that are both connected by a duct system to extinguishing nozzles arranged in the enclosed space. Halon is supplied as a first extinguishing agent from the container to achieve a rapid initial extinguishing of the fire. Nitrogen enriched air is supplied as a second extinguishing agent from the nitrogen generator to achieve a continuous long-term fire suppression, commencing simultaneously with or after the introduction of the Halon. The nitrogen generator may include a molecular sieve to continuously generate the nitrogen enriched air from an inlet flow of environmental air.
