  1. Which NFPA standard specifically addresses the installation, testing, and maintenance of fire alarm systems?

    Answer: NFPA 72

    NFPA 72, the National Fire Alarm and Signaling Code, governs all aspects of fire alarm system design, installation, and testing.

  2. A dual-technology motion detector combines PIR with which other sensing technology to reduce false alarms?

    Answer: Microwave (MW)

    Dual-tech detectors require both PIR and microwave sensors to trigger simultaneously, greatly reducing false alarms from heat sources or air movement alone.

  3. What does 'supervised' mean when applied to a smoke detector power circuit?

    Answer: The panel monitors the circuit for open or short conditions and generates a trouble signal if found

    Supervision means the control panel continuously checks the integrity of the wiring and detects faults that would prevent proper alarm signaling.

  4. Which type of detection is a rate-of-rise heat detector designed to respond to?

    Answer: A rapid increase in temperature exceeding a set rate per minute

    Rate-of-rise detectors trigger when temperature increases faster than a specified rate (typically 12–15°F per minute), catching fast-developing fires earlier.

  5. When a control panel displays a 'ground fault' trouble condition, what does this indicate?

    Answer: An unintended electrical connection between a circuit conductor and earth ground

    A ground fault occurs when insulation breaks down or wiring touches a grounded surface, potentially causing equipment damage or nuisance alarms.

  6. What is the correct procedure before drilling through an existing wall during alarm installation?

    Answer: Use a stud finder and check for hidden electrical wires, pipes, or hazards with an inspection tool or scan

    A technician must verify there are no hidden hazards before drilling to prevent damage to utilities and ensure personal safety.

  7. What is the function of a 'shunt' or 'bypass' in an alarm zone?

    Answer: It temporarily disables a specific zone while keeping the rest of the system armed

    Bypassing a zone excludes it from the armed system, allowing a specific door or sensor to remain open without triggering an alarm.
