Abstract: A fire sprinkler system can include a plurality of fire sensors, each fire sensor adapted to generate an output signal indicative of a fire state; one or more controllers in communication with the plurality of fire sensors, the one or more controllers adapted to calculate one or more fire locations based on output signals received from one or more of the fire sensors; and a plurality of fire sprinklers in communication with the one or more controllers. The one or more controllers can be adapted to open one or more of the fire sprinklers based on the fire location calculated by the one or more controllers. Other features, as well as methods of controlling, suppressing, and/or extinguishing one or more fires, are also described.
