Abstract: A corridor sprinkler includes a frame, a seal, a thermally-responsive trigger, and a deflector. The frame defines a passageway between an inlet and an outlet along a longitudinal axis, the passageway having a nominal K-factor greater than or equal to 8.0. The seal is coupled with the outlet to prevent fluid flow out of the passageway while the seal is in an unactuated state. The thermally-responsive trigger changes the seal from the unactuated state to an actuated state to allow fluid to flow out of the passageway. The deflector is coupled with the frame and distributes fluid received at the inlet at a pressure of between 8 psi and 250 psi and through the passageway to provide a coverage area of between 220 square feet and 400 square feet and a polygonal spray pattern with a long axis length of between 28 feet to 36 feet.

Abstract: Systems and apparatuses of a sprinkler frame having an upper section, a lower section, and a channel extending along a sprinkler axis are provided. The lower section can include apertures through the frame, a guide pin having a first end with a head, a second end, and a shaft extending therebetween. The shaft of the guide pin can translate in an axial direction of the sprinkler axis within the apertures of the sprinkler frame. The deflector can couple with the second end of the guide pin and can include a first side, second side, third side, and fourth side. The first side and the second side may be smaller than the third side and the fourth side and can include an end profile defining a first tine, second tine, third tine, and fourth tine separating a first slot, second slot, and third slot.
