Read the first 7 Inspection & Testing Procedures flashcards as text

  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?

    Answer: 2,000 FPM

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

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

    Answer: Inspection report per NFPA 80 Annex B format

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

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

    Answer: Fail — both functions must be verified

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

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

    Answer: NFPA 90A

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

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

    Answer: No, smoke dampers must close within 10 seconds

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

  6. What is the purpose of applying a 'rattling' or mechanical agitation test during fire damper inspection?

    Answer: To dislodge accumulated dust and confirm blades move freely

    Mechanical agitation confirms that blades are not frozen in place by corrosion or buildup and will move freely when needed.

  7. When replacing a fusible link during inspection, what must the replacement link's temperature rating match?

    Answer: The original manufacturer-specified rating for that damper model

    The replacement fusible link must match the manufacturer-specified temperature rating to maintain the damper's UL listing.
