What determines the maximum width of a fire damper assembly using mullions?

• A. The building code requirements
• B. The fire damper manufacturer
• C. The design preferences of the architect
• D. The cost limitations of the project

Answer: (B)

The maximum width of a fire damper assembly utilizing mullions is primarily determined by the fire damper manufacturer. Manufacturers design their products to meet specific standards and guidelines, which include maximum sizes and configurations for their dampers, based on performance testing, regional codes, and fire safety standards. These specifications ensure that the damper functions correctly during a fire event, maintaining the integrity of fire-rated barriers and preventing the spread of smoke and flames. While building codes, design preferences, and budget constraints can influence the overall design and implementation of the HVAC system, the manufacturer's specifications are crucial for compliance with safety standards and effective performance. The manufacturer’s guidelines will provide the necessary technical information for correctly installing and operating fire dampers, including how to properly incorporate mullions in larger assemblies without compromising safety or functionality.
