Patent

CA 2288859

A fire and smoke damper includes a flat-coil spring actuator to rotate the blades included within the damper between the "normally open" position to the "closed" position when a fire or smoke condition occurs. The damper may include one or more blades, using a linkage connector to ensure simultaneous operation of each blade. The flat-coil spring is held under tension by an actuator (such as a fusible link) to maintain the blades in the "normally open" position. Once the spring is released, a pivot arrangement coupled between the spring and the blade(s) functions to quickly rotate the blade(s) into the closed position, thereby blocking the passage of smoke or fire. The blades may include blade seals to ensure a tight seal.
