  1. Under NFPA 72, what is the maximum allowable distance between smoke detectors in a corridor that is 10 feet wide?

    Answer: 30 feet

    NFPA 72 requires smoke detectors in corridors to be spaced no more than 30 feet apart when the corridor is 10 feet wide or less.

  2. A fire alarm control panel (FACP) displays a 'trouble' signal. What is the FIRST action an FLSD should take?

    Answer: Investigate the source of the trouble condition

    A trouble signal indicates a fault in the system that requires investigation to identify and correct the problem before it compromises system reliability.

  3. Which type of fire alarm initiating device is MOST appropriate for detecting slow, smoldering fires in an office environment?

    Answer: Photoelectric smoke detector

    Photoelectric smoke detectors respond more effectively to the large smoke particles produced by slow, smoldering fires than ionization detectors.

  4. What does a 'supervisory' signal on a fire alarm panel indicate?

    Answer: An off-normal condition exists in a supervised system

    A supervisory signal indicates that a protected system (such as a sprinkler valve) is in an off-normal condition that requires attention but is not yet an alarm.

  5. In a high-rise building, voice evacuation systems are required to provide instructions to occupants. Which area must receive intelligible voice messages FIRST during a fire alarm?

    Answer: The fire floor and the floors immediately above and below

    NFPA 72 and NYC high-rise codes require that voice evacuation messages be directed first to the fire floor and the floors immediately above and below to prioritize those in greatest danger.

  6. A manual pull station is activated but the fire alarm panel shows no alarm. What is the MOST likely cause?

    Answer: The initiating device circuit is open or the pull station is defective

    If a pull station activation does not register on the panel, an open circuit fault or a defective pull station is the most likely cause.

  7. Which NFPA standard governs the installation, testing, and maintenance of fire alarm and signaling systems in the United States?

    Answer: NFPA 72

    NFPA 72, the National Fire Alarm and Signaling Code, is the primary standard governing fire alarm system installation, testing, and maintenance.
