Abstract

See full text

A sprinkler for a fire suppression system includes a body defining an inlet and an outlet fluidly coupled to one another, a frame assembly including a frame member coupled to the body and extending away from the outlet, a deflector coupled to the frame member and offset from the outlet, a seal assembly configured to sealingly engage the body to prevent flow through the outlet, and a trigger assembly. The trigger assembly includes a shape memory alloy element configured to deform from an unactuated configuration to an actuated configuration in response to reaching an activation temperature. In the unactuated configuration, the trigger assembly directly engages both the frame assembly and the seal assembly and holds the seal assembly in sealed engagement with the body. In the actuated configuration, the trigger assembly permits the seal assembly to disengage from the body.
