Read the first 7 Sprinkler Systems flashcards as text

  1. What type of sprinkler system uses a deluge valve and open sprinkler heads throughout the protected area?

    Answer: Deluge system

    A deluge system uses open (non-heat-activated) sprinkler heads and floods all heads simultaneously when the deluge valve opens.

  2. Which NFPA standard specifically governs the installation of sprinkler systems in one- and two-family dwellings?

    Answer: NFPA 13D

    NFPA 13D covers the installation of sprinkler systems in one- and two-family dwellings and manufactured homes.

  3. During a forward flow test of a backflow preventer on a sprinkler system, water flows downstream but the supply shows a pressure loss of 15 psi. This is most likely due to:

    Answer: Normal pressure drop across the backflow preventer

    Reduced pressure backflow preventers and double check assemblies inherently cause a pressure drop, typically 5–15 psi, which is normal.

  4. What is the purpose of an inspectors test connection (ITC) on a wet pipe sprinkler system?

    Answer: To simulate operation of the most remote sprinkler and test alarm devices

    The ITC simulates activation of the hydraulically most remote sprinkler to test the water motor gong, electric alarm, and flow switch without actually discharging sprinklers.

  5. ESFR (Early Suppression Fast Response) sprinklers are designed primarily to protect:

    Answer: High-piled storage occupancies

    ESFR sprinklers deliver large water droplets at high pressure to penetrate fire plumes in high-challenge storage environments.

  6. A sprinkler system piping inspection reveals internal tuberculation and heavy corrosion. Which corrective measure is most appropriate?

    Answer: Perform an obstruction investigation per NFPA 25

    NFPA 25 requires an obstruction investigation when internal corrosion or tuberculation is discovered, which may include flushing or pipe replacement.

  7. Which type of preaction sprinkler system requires BOTH a detection system signal AND a sprinkler head to open before water enters the piping?

    Answer: Double-interlock preaction system

    A double-interlock preaction system requires both detection activation and sprinkler head opening to allow water flow, providing the highest protection against accidental discharge.
