Read the first 7 Inspection & Quality Control flashcards as text

  1. During an inspection of a smoke detector, the technician finds a layer of dust inside the sensing chamber. What is the correct action?

    Answer: Clean the chamber with compressed air and document the finding

    Dust in the sensing chamber can cause false alarms or reduced sensitivity, so cleaning and documenting the condition is required.

  2. What does NFPA 72 require regarding the spacing of heat detectors in a standard ceiling height room?

    Answer: Detectors must not exceed a listed spacing, typically 50 ft between units

    NFPA 72 limits heat detector spacing based on the listed spacing provided by the manufacturer, commonly up to 50 ft.

  3. A pull station is found to be stuck in the activated position during inspection. What should the technician do first?

    Answer: Notify the building owner and place the panel in alarm bypass while repairing

    The owner must be notified, and the impaired zone should be managed per NFPA 72 impairment procedures before repair.

  4. Which test verifies that an alarm signal initiated at a field device is received correctly at the central monitoring station?

    Answer: End-to-end functional test

    An end-to-end functional test confirms the complete signal path from the initiating device through the panel to the monitoring station.

  5. When inspecting a control panel, the technician observes that a trouble LED has been masked with tape. What should be done?

    Answer: Remove the tape, investigate the underlying trouble condition, and document findings

    Masking indicators is a code violation; the underlying trouble must be identified and corrected per NFPA 72.

  6. An inspection reveals that a duct smoke detector is installed in a supply air duct. What minimum airflow velocity is typically required for reliable duct detector operation?

    Answer: 100 to 4,000 ft/min as specified by the manufacturer

    Duct smoke detectors are listed for specific airflow velocity ranges, most commonly between 100 and 4,000 ft/min.

  7. After completing an annual inspection, which document should the technician leave on-site?

    Answer: A signed inspection record indicating findings, corrections, and the date

    NFPA 72 requires that a record of the inspection be maintained on the premises and be available to the AHJ.
