  1. Under OSHA's lockout/tagout (LOTO) standard, when must an alarm technician re-verify that energy is isolated before working on a panel?

    Answer: After any interruption or shift change that breaks continuous control of the lockout device

    OSHA 29 CFR 1910.147 requires energy re-verification whenever continuous personal control of the lockout device is broken.

  2. Which NFPA standard primarily governs the installation of fire alarm systems in the United States?

    Answer: NFPA 72

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

  3. A technician is installing wiring in a commercial building and must run alarm cable through the same conduit as 480 V power wiring. This is:

    Answer: Prohibited by NEC Article 760

    NEC Article 760 prohibits fire alarm circuit conductors from being run in the same conduit as power conductors unless specific exceptions apply.

  4. What does the term 'listed' mean when applied to alarm equipment?

    Answer: The equipment is included in a recognized testing laboratory's published list of compliant products

    'Listed' means a product has been evaluated and certified by a nationally recognized testing laboratory (NRTL) such as UL.

  5. When performing a fire alarm inspection, a technician discovers that a pull station is painted over. The correct action is to:

    Answer: Replace or restore the pull station to manufacturer specifications and report the deficiency

    A painted pull station is a deficiency because paint can prevent proper operation; it must be restored or replaced per NFPA 72.

  6. A Class A initiating device circuit (IDC) differs from Class B primarily in that Class A:

    Answer: Provides a supervised return path so a single open fault does not disable the entire circuit

    Class A circuits use a return path (loop) so that a single open will not prevent all devices from reporting; Class B will lose devices beyond the fault.

  7. What is the minimum battery standby time required by NFPA 72 for a fire alarm system in a non-supervising station configuration?

    Answer: 24 hours

    NFPA 72 requires a minimum of 24 hours of standby power followed by 5 minutes of alarm for most non-supervising-station fire alarm systems.
