The International Fire Code (IFC) requires periodic testing of life safety dampers and smoke control systems. There are some state or local variations, but the requirements are essentially the same in all of the U.S.
NFPA 80 Sections 19.4.1 and 19.4.1.1 and NFPA 105 Sections 6.5.2.1 and 6.5.2.2 and state the periodic requirements: inspect and test life safety dampers one year after installation, then every four years; in hospitals, every six years. This sets the periodic testing requirements for dampers installed under Chapter 7.
