Systems and methods for fire suppression in a corridor

A fire suppression system, comprising:

• a fire suppression material source storing a fire suppression material;
• at least one fire protection sprinkler for corridor applications, comprising:
• a frame defining 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;
• a seal coupled with the outlet to prevent fluid flow out of the passageway while the seal is in an unactuated state;
• a thermally-responsive trigger that changes the seal from the unactuated state to an actuated state to allow fluid to flow out of the passageway;
• and
• a deflector coupled with the frame, the deflector is planar and comprises a first side, a second side, a third side, and a fourth side, the third side and the fourth side are tineless, the first side and the second side smaller than the third side and the fourth side, the first slot and the third slot are mirrored relative a deflector axis centered between and extending along the third side and the fourth side, the first side and the second side each comprise:
• an end profile defining a first tine separated from a second tine by a first slot, a third tine separated from the second tine by a second slot, and a fourth tine separated from the third tine by a third slot;
• and
• a first depth of the first slot is greater than a second depth of the second slot;
• the deflector 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;
• and
• a piping system coupled with the at least one fire protection sprinkler and the fire suppression material source, the piping system transmits the fire suppression material from the fire suppression material source to the at least one fire protection sprinkler.
