FSD Inspection & Testing Procedures 3

Question 1

Under NFPA 92, what is the minimum air velocity at which a smoke damper must be tested to verify it can close against airflow?

Accepted Answer

2,000 FPM

Answer

NFPA 92 requires smoke dampers to be tested against an airflow of at least 2,000 FPM to simulate realistic duct conditions.

Question 2

Which document must an inspector complete to record all findings from a fire and smoke damper inspection?

Accepted Answer

Inspection report per NFPA 80 Annex B format

Answer

NFPA 80 Annex B provides a standardized format for documenting inspection and test results for each damper.

Question 3

A combination fire/smoke damper fails its smoke control test but passes the fire test. How should it be classified?

Accepted Answer

Fail — both functions must be verified

Answer

A combination damper must satisfy both fire damper and smoke damper requirements; failure of either function is an overall failure.

Question 4

Which authority having jurisdiction (AHJ) standard most directly governs the inspection cycle of smoke dampers in commercial HVAC systems in the US?

Accepted Answer

NFPA 90A

Answer

NFPA 90A, Standard for the Installation of Air-Conditioning and Ventilating Systems, sets inspection requirements for smoke dampers in HVAC applications.

Question 5

During testing, a smoke damper closes but takes 35 seconds to reach the fully closed position. Is this acceptable?

Accepted Answer

No, smoke dampers must close within 10 seconds

Answer

Smoke dampers must close within 10 seconds of receiving the control signal per NFPA 92 requirements for effective smoke control.
