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.

An actuator system includes a shaft hub having a shaft and one or more rotation arms coupled to the shaft, one or more shape memory alloy springs coupled to the one or more rotation arms, and as a voltage source configured to apply a voltage to the one or more shape memory alloy springs. The voltage causes the one or more shape memory alloy springs to change in size or shape, thereby applying a force to the one or more rotation arms and causing the shaft hub to rotate. The actuator system also includes a processing circuit configured to receive an indication of a desired incremental rotation for the shaft hub and apply a voltage corresponding to the desired incremental rotation to the one or more shape memory alloy springs, causing the shaft and the shaft hub to rotate about a central axis.

A hinge assembly is provided. The hinge assembly includes a first hinge component and a second hinge component. The first hinge component includes a leaf portion terminating in a first knuckle and a second knuckle. The first knuckle includes a protrusion and the second knuckle includes a recess. The second hinge component is rotatably coupled to the first hinge component and is structurally identical to the first hinge component. The protrusion of the first hinge component is configured to fit within the recess of the second hinge component, and the protrusion of the second hinge component is configured to fit within the recess of the first hinge component.

An enclosure for a film-type humidity sensing element includes identical enclosure members which snap together to form an enclosure with the humidity sensing element sandwiched between the members, each of the members including a lead mounting area on its inner surface for mounting the mounting ends of electrical leads, the leads being connected to contact portions of the humidity sensing element interiorly of the enclosure by a metal-filled conductive adhesive which is introduced into the enclosure through access openings after the enclosure members have been assembled together. The enclosure is adapted for mounting on a circuit board in both horizontal and vertical orientations and independently of the lead structure of the sensor assembly.
