Overview:  Fire dampers covered under UL555 & UL555S standard are intended for installation in accordance with Dubai Civil Defence Approved and have UL Certification Marks for all air conditioning and ventilation system. A fire damper is specifically installed in fire resistive rated assemblies where ducts penetrate and air transfer openings are there. In case of a fire, fire dampers shut automatically to prevent the propagation of fire and smoke through ductwork to adjacent designated fire compartments. Ducting should be installed in such a manner that it does not impose any loads on the fire damper in case of a fire.

Fire dampers are an important part of the fire protection system. It works when the heat from the fire causes the normal temperature of a room to rise to certain temperature. The fusible link attached to the damper would then melt, and then causing the damper’s door to close. Where the temperature is constantly higher, a higher degree fusible link would be attached to the damper.

Fire damper, a device that is installed in ducts and air transfer opening of an air distribution or smoke control system which is designed to close automatically upon detection of heat. It also serves to interrupt migratory airflow, resist the passage of flame, and maintain the integrity of the fire rated separation. Its primary function is to prevent the passage of flame from one side of a fire-rated separation to the other. This is the reason that maintenance and regular inspection is also essential. It gives you the guarantee that in case of fire, the fire dampers will operate correctly and do the job efficiently. Fire dampers are installed in or near the wall or floor, at the point of duct penetration, to retain the integrity and fire rating of a wall or floor whether it is a ducted or open-plenum return application.
