Air Movement, Control Association: Code changes allow remote periodic testing of life-safety dampers
Life-safety dampers are critical fire-protection features of buildings. By protecting duct and air-transfer-opening penetrations through fire- and smoke-rated construction, they help to contain fire and smoke within the area of origin. Like any mechanical device, life-safety dampers need to be exercised and tested periodically to ensure they will work as designed when needed. Chapter 7 of the International Fire Code requires that fire dampers be maintained in accordance with NFPA 80, “Standard for Fire Doors and Other Opening Protectives,” and that smoke dampers be maintained in accordance with NFPA 105, “Standard for Smoke Door Assemblies and Other Opening Protectives.”
The 2019 editions of NFPA 80 and NFPA 105 include important changes concerning the maintenance of fire and smoke dampers. This article explains those changes and how they can significantly reduce costs while making buildings safer.
