Which statement about fire-rated door assemblies is INCORRECT?

1. Either hinges or rated pivots may be used

2. Labeling is required for both the door and frame

3. Glass area is limited based on rating

4. A closer is always required

The correct answer is: A closer is always required

The statement that a closer is always required for fire-rated door assemblies is incorrect. While fire-rated doors may often include a closer to ensure that the door automatically closes and latches, it is not an absolute requirement in every situation. There are specific circumstances, such as when the door is part of a door series or when the door is self-closing or self-latching, where a closer might not be necessary. In contrast, the other assertions are accurate. Both hinges and rated pivots can be utilized in fire-rated door assemblies, which allows for flexibility in design and installation. Labeling is indeed required for both the door and frame to ensure that the fire rating is easily identifiable, which is crucial for maintaining safety standards. Additionally, the glass area in a fire-rated door assembly is limited based on its rating to prevent the spread of fire and maintain the structural integrity of the door during a fire event.
