Controlled system and methods of storage structure fire protection

A system of ceiling-only fire protection of a storage structure, comprising:

• a plurality of fluid distribution devices disposed in a grid pattern beneath a ceiling and above the storage structure having a nominal storage height less than a nominal ceiling height, wherein each of the plurality of fluid distribution devices includes a frame body with a seal assembly disposed therein and an actuator arranged with the frame body to displace the seal assembly to control a flow of water discharge from the frame body;
• a fluid distribution system including a network of pipes interconnecting the plurality of fluid distribution devices with a water supply;
• a plurality of detectors to monitor the storage structure for a fire;
• and
• a controller coupled with the plurality of detectors to detect and locate the fire, the controller being coupled to the plurality of fluid distribution devices to identify and control operation of a select number of the plurality of fluid distribution devices that define a discharge array above and about the fire, the controller:
• receives an input signal indicating the fire from at least some of the plurality of detectors;
• identifies, using the input signal, a first detector of the at least some of the plurality of detectors sensing a highest temperature;
• and
• determines adjacency of each of the at least some of the plurality of detectors relative to the first detector based on respective locations of each of the at least some of the plurality of detectors in the grid pattern.
