Which of the following is not a requirement for a fire-rated door assembly in a high-rise building?

  1. Non-combustible frame

  2. Self-closing device

  3. Labeled with a fire rating

  4. Minimum height of 2.4 meters

The correct answer is: Minimum height of 2.4 meters

The minimum height of 2.4 meters is not a requirement for a fire-rated door assembly in a high-rise building. Although a fire-rated door assembly should have a minimum height to ensure proper function and coverage, it is not a requirement specifically for high-rise buildings. All other options (non-combustible frame, self-closing device, and labeled with a fire rating) are necessary for a fire-rated door assembly in any building, including high-rise buildings.
