Fire damper inspection under NFPA 80 and NFPA 105: the 1-year, 4-year and 6-year rule
NFPA 80 (fire dampers) and NFPA 105 (smoke dampers) require a test after installation, another one year later, and then every 4 years, or every 6 years in hospitals. What the test involves, why access is the real obstacle, and keeping a per-damper record.
By Hovermarks team
Quick answer. NFPA 80 covers fire dampers and NFPA 105 covers smoke dampers, and both set the same schedule: test after installation, again one year after installation, then every 4 years. In hospitals the interval after the first year is every 6 years. Each test is an operational test of that damper, and the most common reason a building falls behind is that the dampers cannot be reached.
Fire and smoke dampers are among the most numerous life-safety devices in a commercial building and among the least visited. They sit inside ductwork above finished ceilings, they are tested only every few years, and nobody notices a stuck damper until the day it needs to close. Surveyors and fire marshals know this, which is why damper records are a frequent finding.
The schedule
| Inspection | When |
|---|---|
| Acceptance test | After installation |
| First periodic test | One year after installation |
| Ongoing tests | Every 4 years |
| Ongoing tests, hospitals | Every 6 years |
The clock is per damper. A building that added a wing in 2022 carries a different cycle for those dampers than for the original installation, and a damper replaced last year restarts at its one-year test.
What the test involves
For a fire damper, the inspector:
- removes the fusible link or other heat-responsive device so the damper can operate
- confirms the damper closes fully, with nothing in the duct blocking it, and latches where a latch is fitted
- resets the damper, replaces the link, and lubricates moving parts where the manufacturer requires it
- records the result for that damper, including any it could not reach
For a smoke damper under NFPA 105, the test operates the damper from its control, such as the fire alarm system or a duct smoke detector, and confirms it reaches its full position and returns.
The access problem
Most overdue damper programs are not overdue because nobody scheduled them. They are overdue because a third of the dampers sit above a ceiling with no access panel, behind ductwork added later, or in a space that cannot be shut down. The practical first step is a survey: find every damper, give it an identity, record its location and whether it can be reached, and raise every inaccessible one as a defect to fix with an access door.
Records
Each inspection and test is documented per damper, with the result and any repair needed, and the records are kept available for the AHJ and for accreditation surveyors in healthcare. A record that says "all dampers on level 3 tested" does not show which damper was found blocked or which one was skipped.
Where Hovermarks fits
Hovermarks gives each damper its own QR-tagged identity, with its location, type and next-due date on its own 1-year, 4-year or 6-year cycle. The test runs as a configurable checklist on a phone with photos, a failed or unreachable damper raises a defect against that damper, and the history survives a change of contractor. The fire inspection solution shows the workflow.
