  1. What is the purpose of a 'Class E' fire alarm system in NYC high-rise office buildings?

    Answer: A voice communication system for floor-by-floor announcements and two-way communication

    Class E fire alarm systems include voice communication capabilities, allowing the FLSD to make floor-by-floor announcements and maintain two-way communication with floor wardens and FDNY.

  2. Stairwell pressurization systems in high-rise buildings are designed to:

    Answer: Push air into stairwells to prevent smoke infiltration during evacuation

    Stairwell pressurization systems inject air into enclosed stairwells to create positive pressure, preventing smoke from entering the primary evacuation routes.

  3. Which type of sprinkler head responds fastest to heat and is typically used in high-hazard areas?

    Answer: Quick response sprinkler (RTI ≤ 50)

    Quick response sprinklers have a lower Response Time Index (RTI ≤ 50) and activate faster than standard sprinklers, providing earlier suppression in high-hazard environments.

  4. When a smoke detector activates in an elevator machine room, the elevator system should automatically:

    Answer: Return all elevators to the lobby and prevent them from returning to the machine room floor

    Smoke detection in elevator machine rooms triggers automatic recall of all elevators to the lobby, preventing them from traveling to the fire-affected area.

  5. A high-rise building's roof exhaust fans are part of the smoke control system. During a fire, they are used to:

    Answer: Exhaust smoke from the building to assist in visibility and evacuation

    Roof exhaust fans remove smoke from the building, improving visibility in evacuation routes and reducing toxic smoke exposure for occupants and firefighters.

  6. The FLSD notices that a sprinkler control valve in the basement has been shut off. The correct action is to:

    Answer: Post a fire watch and document the impairment in the fire safety log

    A shut sprinkler valve constitutes a fire protection impairment. The FLSD must post an immediate fire watch for the affected area and document the condition per NYC Fire Code requirements.
