Read the first 7 Fire Safety Equipment and Alarm Systems flashcards as text

  1. A photoelectric smoke detector is BEST suited for detecting which type of fire?

    Answer: Slow, smoldering fires that produce heavy smoke

    Photoelectric detectors use a light beam and are most effective at detecting slow, smoldering fires that produce large smoke particles.

  2. What does a yellow/amber LED status light typically indicate on a fire alarm control panel?

    Answer: A trouble or supervisory condition exists

    Yellow or amber LEDs on a fire alarm panel indicate a trouble or supervisory condition that needs attention but is not an active fire alarm.

  3. Which class of fire extinguisher is REQUIRED near a server room or electrical equipment area?

    Answer: Class C

    Class C extinguishers use non-conductive agents and are required for energized electrical equipment fires.

  4. A wet pipe sprinkler system differs from a dry pipe system in that wet pipe systems:

    Answer: Are always pressurized with water ready to discharge

    Wet pipe systems keep water pressurized in the pipes at all times, allowing immediate discharge when a sprinkler head activates.

  5. What is the recommended minimum travel distance between fire extinguishers in a commercial building for Class A hazards according to NFPA 10?

    Answer: 75 feet

    NFPA 10 requires that Class A extinguishers be placed so no point in the building is more than 75 feet of travel distance from an extinguisher.

  6. A fire alarm system's 'supervisory signal' is triggered when:

    Answer: A monitored system component moves out of its normal position (e.g., a closed sprinkler valve)

    Supervisory signals alert that a monitored device — such as a sprinkler control valve — has moved to an abnormal position that could impair the system.

  7. Carbon monoxide detectors should be installed at what height in a residential setting?

    Answer: At breathing level, typically 5 feet from the floor, or per manufacturer instructions

    CO detectors should be installed at breathing level (about 5 feet) or per the manufacturer's instructions, since CO mixes evenly with air.
