Fire dampers are UL555 tested and labeled devices installed in ducts and air transfer openings or air distribution systems, designed to close upon the detection of heat. Air is distributed in air-conditioning and ventilating systems by ducts and plenums and for the system to reach everywhere it needs to within the building, it may require penetrating fire-resistance rated assemblies or assemblies protected against the transfer of smoke. Like fire doors protecting. Here is the definition of a Fire Damper according to the NFPA (National Fire Protection Association). “A fire damper is designed to, and required to, close automatically upon detection of heat (such as a fusible link or heat detector) and to interrupt airflow and to restrict the passage of flame. HVAC dampers are used to regulate airflow in the system design, fire dampers are put into HVAC. ABB offers an innovative enclosure system for fire prevention, which is constructed of fireproof materials, features optimum technology and is available in a variety of economical designs. The International Building Code (IBC) Section 717 and the International Mechanical Code (IMC).
