Fire extinguishing system for large structures
First Claim
1. A fire suppression system for detecting and suppressing fires in a protected space, comprising:
- (a) a plurality of reservoirs, each said reservoir containing a fire retardant;
(b) a piping network, selectably providing fluid communication between said plurality of reservoirs, and to a plurality of sprinklers, each said sprinkler being associated with a predetermined localized portion of the protected space;
(c) at least one valve;
(d) at least one fire detector, said at least one fire detector associated with a predetermined localized portion of said protected space.

Abstract
A method and system for detecting and extinguishing fires, and for sharing fire retardant throughout a network of interconnected reservoirs, is self-sealing and autonomous. The system isolates reservoirs when interconnection piping is damaged, and shares retardant to the fire location(s) as needed by routing retardant through undamaged piping segments. Reservoir sensors, fire sensors, damage sensors, valves, redundant and spatially separated flow paths, controllers, and manual over-rides all provide the method and system for detecting and extinguishing major fires automatically, and reacting to system damages. The system is best suited for large buildings or structures such as office buildings, large-scale warehouses, sky-scrapers, cruise ships, aircraft carriers, and the like.

17. A fire suppression system for detecting and suppressing fires in a protected space, comprising:
-
(a) a plurality of reservoirs, each said reservoir containing a fire retardant, and each said reservoir having a retardant level sensor;
(b) a piping network, selectably providing fluid communication between said plurality of reservoirs, and to a plurality of sprinklers, each said sprinkler being associated with a predetermined localized portion of the protected space;
