CEILING-ONLY DRY SPRINKLER SYSTEMS AND METHODS FOR ADDRESSING A STORAGE OCCUPANCY

摘要

A ceiling-only dry sprinkler system configured to address a storage occupancy fire event with a sprinkler operational area sufficient in size to surround and drown the fire. The system and method preferably provide for the surround and effect by activating one or more initial sprinklers, delaying fluid flow to the initial activated sprinklers for a defined delay period to permit the thermal activation of a subsequent one or more sprinklers so as to form the preferred sprinkler operational area. The sprinklers of the operational area are preferably configured so as to provide sufficient fluid volume and cooling to address the fire-event with a surround and drown configuration. The defined delay period is of a defined period having a maximum and a minimum. The preferred sprinkler system is adapted for fire protection of storage commodities and provides a ceiling only system that eliminates or otherwise minimizes the economic disadvantages and design penalties of current dry sprinkler system design.

主权项

1. A ceiling-only dry sprinkler system for protection of a storage occupancy comprising:
a network of pipes including a wet portion and a dry portion connected to the wet portion, the dry portion configured to respond to a fire with at least a first activated sprinkler; and a mandatory fluid delivery delay period to deliver fluid from the wet portion to the at least first activated sprinkler, the delay period being of a sufficient length such that the dry portion further responds to the fire with at least a second activated sprinkler, the at least first and at least second actuated sprinklers defining a sprinkler operational area sufficient to surround and drown a fire event.
