Fire Dampers are usually required to be installed wherever air distribution systems penetrate a rated assembly. Fire Dampers are used in HVAC ductwork. The fire damper automatically interrupts the flow of air through the duct system during an emergency. It restricts the passage of smoke, fire and heat. It must be installed whenever a duct passes through a wall, ceiling or floor that is part of a fire-rated assembly. A fire damper includes a fusible link on either side of the assembly the duct penetrates. This link melts during a fire, causing the fire damper to close and seal the duct. Access for maintenance and inspection of fire dampers is required by the building codes. Access doors are normally installed at fire dampers for servicing and inspection.
