What are Fire Dampers
Fire dampers are passive fire protection products used in heating, ventilation, and air conditioning (HVAC) ducts to dramatically reduce the spread of fire inside the ductwork through fire-resistance rated walls and floors.
Fire/smoke dampers are similar to fire dampers in fire resistance rating, and also prevent the spread of smoke inside the ducts. When a rise in temperature occurs, the fire damper closes, usually activated by a thermal element which melts at temperatures higher than ambient, but low enough to indicate the presence of a fire, allowing springs to close the damper blades. Fire dampers can also close following receipt of an electrical signal from a fire alarm system utilising detectors remote from the damper, indicating the sensing of heat or smoke in the building occupied spaces or in the HVAC duct system.
