  1. Under F80 code requirements, which type of fire alarm system wiring configuration provides the highest level of circuit survivability during a fault?

    Answer: Class X

    Class X circuits provide the highest survivability by using redundant pathways that allow continued operation even during multiple simultaneous faults.

  2. NFPA 72 requires that a fire alarm annunciator panel, when provided, must be located:

    Answer: Where it is readily accessible to responding fire department personnel

    Annunciator panels must be located where first responders can easily access and read them upon arrival at the building.

  3. According to F80 code requirements, duct smoke detectors are primarily required to:

    Answer: Shut down HVAC equipment to prevent smoke spread

    Duct smoke detectors are installed to detect smoke in HVAC ducts and shut down air handling equipment to prevent smoke from being distributed throughout a building.

  4. Under NFPA 72, a 'verification' feature on an addressable smoke detector means the panel will:

    Answer: Delay the alarm signal for 60 seconds while rechecking the detector

    Alarm verification allows the panel to reset and re-sample the detector after a brief delay (typically 60 seconds) to reduce nuisance alarms from transient conditions.

  5. According to F80 code requirements, carbon monoxide (CO) detectors installed as part of a fire alarm system must be listed to which UL standard?

    Answer: UL 2075

    CO detectors used in fire alarm systems must be listed to UL 2075, the standard for Gas and Vapor Detectors and Sensors.

  6. Under F80 code requirements, a signaling line circuit (SLC) used in an addressable fire alarm system must be supervised for which type of fault?

    Answer: Open, short, and ground faults

    NFPA 72 requires addressable SLCs to be supervised for open circuits, short circuits, and ground faults to ensure circuit integrity.

  7. According to NFPA 72, when is it permissible to use a single station smoke alarm in lieu of a system smoke detector in a dwelling unit?

    Answer: When the dwelling is a one- or two-family home not requiring a system

    Single station smoke alarms are acceptable in one- and two-family dwellings not requiring a full fire alarm system under NFPA 72 Chapter 29.
