Summary: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. Inthe 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. 一种用于火灾抑制系统的喷洒器包括：主体，所述主体限定彼此流体地联接的入口和出口；框架组件，所述框架组件包括联接至所述主体并且背离所述出口延伸的框架构件；导流器，所述导流器联接至所述框架构件并且偏离所述出口；密封组件，所述密封组件被构型成密封地接合所述主体，以防止流穿过所述出口；以及
