Abstract
A damper of a heating, ventilation, and/or air conditioning (HVAC) system includes a crank configured to rotate about an axis of a shaft relative to a support, a reset arm configured to rotate about the axis of the shaft relative to the support, a spring coupled to the crank and the reset arm, and a fuse link configured to be coupled to the reset arm and the support in a set configuration and to release the reset arm from the support in response to a temperature exceeding a threshold temperature. The crank and the reset arm are configured to rotate away from the support in a first circumferential direction toward a closed configuration in response to the fuse link releasing the reset arm from the support. A spring force of the spring is configured to increase to enable the reset arm to rotate in a second circumferential direction opposite to the first circumferential direction beyond the set configuration and into a reset configuration.
