What feature distinguishes a smoke damper from a fire damper?

• A. Smoke dampers are larger in size
• B. Smoke dampers can only be activated manually
• C. Smoke dampers are designed to close in the presence of smoke, regardless of fire
• D. Smoke dampers operate at a higher temperature

Answer: (C)

The distinguishing feature of a smoke damper is that it is specifically designed to close in the presence of smoke, regardless of whether there is a fire. This capability is crucial in smoke control systems within buildings, as it helps to contain and redirect smoke to designated areas, enhancing life safety and aiding fire control measures. In contrast, fire dampers are primarily intended to resist the passage of flame and hot gases. They respond to the high temperatures associated with a fire event rather than smoke presence. This distinction is vital in the context of HVAC systems, where effective smoke management can make a significant difference in occupant safety during a fire. Therefore, identifying that smoke dampers function based on the presence of smoke highlights their unique purpose in fire safety strategies, making this option the correct choice.
