Dry sprinkler system and design methods

Abstract

A dry fire protection system, preferably for a storage occupancy, and its method of design are provided in which a fluid delivery delay period is identified and implemented. The preferred design method includes defining a ceiling height, a storage configuration, and storage height. The hydraulic demand for a wet system protecting the same defined storage occupancy is then identified. A fluid delivery delay period is then determined for the dry sprinkler system, preferably a maximum ADT, which results in a sprinkler operational area having a total number of sprinkler activations less than or equal to that defining the total hydraulic demand of the wet system. The preferred dry system can be further configured such that each and every sprinkler in the system has a fluid delivery delay period equal to or less than the maximum fluid delivery delay period.
