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

Non-combustible frame

Self-closing device

Labeled with a fire rating

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.
