Apparatus and Related Methods for Deactivating Fire Sprinkler Heads

Abstract

Disclosed are an apparatus and related methods for quickly deactivating or otherwise plugging a sprinkler, wherein the deactivated sprinkler may automatically reactivate in view of an unexpected fire. Generally, the disclosed apparatus comprises: a piston pump that is in fluid communication with an inflatable bladder. In one mode of operation, the bladder of said apparatus may be disposed within a nozzle of a sprinkler, the piston pump operated to inflate the bladder, and wherein said inflated bladder blocks fluid from escaping the nozzle. Suitably, the working components of the apparatus may be configured to melt whenever ambient temperatures surrounding the sprinkler reach a threshold level so that the sprinkler may reactivate in view of an unexpected fire in its proximity.
