Abstract
A radiation-activated sprinkler includes a sprinkler body defining a main orifice, the main orifice adapted to couple to a source of pressurized liquid; a deflector coupled to the body; a valve adapted to seat on the main orifice to block the source of pressurized liquid; a linkage mechanism adapted to retain the valve on the main orifice; and one or more fusible links coupled to the linkage mechanism, wherein the one or more fusible links are located substantially externally with respect to the sprinkler body, deflector, and linkage mechanism. The one or more fusible links are adapted to release when exposed to an amount of radiation that exceeds a predetermined threshold, thereby releasing the linkage mechanism from the valve. Other features and related methods are also described.
