Abstract: A concealed sprinkler includes a body, a seal, an activation element, a deflector, and a nosecone. The body includes a passageway having an inlet and an outlet, and defines a longitudinal axis through the inlet and the outlet. The seal couples with the outlet. The activation element couples with the seal. The activation element changes from a first state to a second state responsive to a fire condition to allow the seal to be displaced from the outlet. The deflector is coupled with the body and positioned along the longitudinal axis. The nosecone is coupled with the deflector and includes a first portion positioned along the longitudinal axis, a second portion spaced from the first portion and extending further outward than the first portion, and a wall forming a step between the first portion and the second portion.
