Fire Door Assembly: Which components are included?

• A. A door, frame, hardware, and accessories that together provide fire protection.
• B. The door leaf only.
• C. A window assembly.
• D. A non-rated door.

Answer: (A)

Fire door assemblies are evaluated as a complete unit. The rating and protective capability apply to the whole assembly, not just the door leaf. This means the door, its frame, the hardware (hinges, latches, closer, strikes), and any accessories such as seals or vision panels must be included and listed to work together to provide the required fire resistance. If you only have the door leaf, you don’t have a complete assembly that offers fire protection. A window assembly is not a door assembly, and a non-rated door does not meet fire protection requirements. Thus, the correct understanding is that a fire door assembly includes the door, frame, hardware, and accessories that together provide fire protection.
