1.General Description
ESFR (Early Suppression Fast Response) sprinkler systems are designed to achieve fire suppression for a specific type of storage occupancy before the fire becomes fully developed. ESFR heads vary with K-factors of 11.2, 14.0, 16.8 ,22.4 and 25.2 with as well as pressures of 50 and 70 psi. In most cases ESFR systems have not been tested for non-storage occupancy.
Suppression-mode sprinklers that are
especially advantageous as a means of
eliminating the use of in-rack sprinklers
when protecting high-piled storage.
This sprinkler is designed to respond quickly to growing fires and will deliver a heavy water discharge to "suppress" rather than "control" fires.

3.Operation
The fusible link assembly is comprised of two link halves that are joined together by a thin layer of solder. When the rated temperature is reached, the solder melts and the two link halves separate, activating the sprinkler and flowing water
