A fire damper is designed to close to restrict the spread of fire. Fire dampers are made with loaded opposed damper blades held open by a fusible link that is temperature rated either 165°F or 212°F. When excessive heat occurs, the fusible link melts and a high torque spring immediately closes the blades and shuts off the air supply. Once the damper closes, it must be manually reopened and a new single use fusible link must be installed. Typically the code will specify the link temperature. The 212°F links are used in attics and ceilings where 165°F links can cause nuisance failures.

Johnson Controls’ Multi-blade Fire dampers are UL Standard 555 rated for 1.5 hours. These dampers meet the requirements of the 1996 edition of NFPA-90A for use in a fire partition rated less than three hours. They are dynamically rated for up to 3500 fpm air flow and 8 inches static pressure. Packed with the dampers are NFPA-90B Certified Installation Instructions that help you comply with the installation codes.

With more emphasis being placed on the safety of the building occupants, more buildings are being equipped with life safety devices to prevent loss of life in an emergency. Building codes are being tightened to limit the spread of fire and smoke within buildings. Johnson Controls’ SD-1300 Series Smoke Dampers are two dampers in one. They are actuated by either an 8–13# pneumatic or an electric two-position actuator for control use. When closed, these dampers are leakage rated and tested in accordance with UL Standard 555S. Actuators are UL rated for this service and are only available factory installed as a matched set with the damper.
