A fusible link is a device made of a special metal alloy that is designed to melt during a fire. The fusible link goes on a Discharge Door and holds the door in a “open” position. If a fire occurs, the heat from the flames will melt the link, thus releasing the door and closing off the chute line to prevent smoke and fire from using the chute to spread to other floors.
