ABSTRACT:
A device for terminating the flow of fire-extinguishing fluid from an activated sprinkler head of the pendent and sidewall types. A cavity within the device receives the sprinkler head and a protuberance within said cavity engages the valve assembly and returns the shut-off valve to the fluid-emitting conduit. Biased apertures within the sidewalls engage the sprinkler head flange and provide a locking means. The device is constructed from thermoplastic resins which melt and allow the device to become reactivated when ambient temperatures reach critical levels.
