Abstract: System and methods of protecting against the spread of fire. A method includes receiving data from at least one sensor. The method determines whether the data satisfies risk criteria for a first zone and/or a second zone of a plurality of zones of a structure. The first zone is associated with a first set of nozzles of a plurality of nozzles and the second zone is associated with a second set of nozzles of the plurality of nozzles. In accordance with a determination that the data satisfies the risk criteria for the first zone and not the second zone, the method provides first instructions to a pump to distribute a fire suppressant from a reservoir via a supply line fluidically coupled to the plurality of nozzles. The method further provides second instructions to a manifold to distribute the fire suppressant via the first set of nozzles and not the second zone.
