What is the maximum installation distance, in inches, of a smoke damper from a smoke barrier?

• A. 10
• B. 18
• C. 24
• D. 30

Answer: (C)

The maximum installation distance of a smoke damper from a smoke barrier is specified in various NFPA standards, particularly NFPA 92, which focuses on smoke management systems. The standard defines that smoke dampers must be located within a specific distance to ensure their effectiveness in containing smoke and maintaining the integrity of the smoke barrier. Choosing 24 inches as the correct installation distance reflects the requirement that the damper needs to be within a limit that allows it to operate efficiently in controlling smoke movement during a fire event. If the damper were installed too far away, it could compromise the effectiveness of the smoke control system and potentially lead to smoke spreading beyond the desired barriers, increasing risks to life and property. The other distances provided do not align with the standard requirements, as they either exceed the maximum distance or fall short of the necessary operational parameters for ensuring effective smoke control. Understanding these specifications is crucial for maintaining safety standards in buildings equipped with HVAC systems.
