According to
NFPA 80A, the standard refers users to NFPA 80 for specific inspection and testing requirements related to fire dampers. As outlined in NFPA 80, fire dampers must be inspected and tested one year after installation and every 4 years thereafter (or every 6 years in hospitals).
These inspections help ensure that dampers function properly in the event of a fire and that no obstructions or mechanical failures compromise the barrier’s integrity.
