Systems and methods of nosecones of concealed sprinklers

A nosecone of a sprinkler, comprising:

• a first portion through which a longitudinal axis extends, the first portion having a first central surface perpendicular to the longitudinal axis and a first outer surface around the first central surface, the first outer surface angled relative to the first central surface;
• a second portion spaced from the first portion and extending further outward than the first portion relative to the longitudinal axis;
• and
• a wall forming a step between the first portion and the second portion.

A sprinkler assembly, comprising:

• a body that includes a passageway, the passageway has an inlet and an outlet, the passageway defines a longitudinal axis through the inlet and the outlet;
• a seal to couple with the outlet;
• an activation element coupled with the seal, the activation element to change from a first state to a second state responsive to a fire condition to allow the seal to be displaced from the outlet;
• a deflector coupled with the body and positioned along the longitudinal axis;
• a plurality of guide pins coupled with the deflector and the body;
• and
• a nosecone coupled with the deflector, the nosecone comprising 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.
