In what scenario might a manual override be necessary for smoke dampers?

• A. To standardize airflow in all situations
• B. To control airflow in emergency situations
• C. For routine maintenance checks
• D. To enhance system efficiency

Answer: (B)

A manual override is necessary for smoke dampers primarily to control airflow in emergency situations. In the event of a fire or smoke event, the automatic operation of smoke dampers may not suffice if rapid manual intervention is required to ensure smoke is contained or directed appropriately. This manual control can help ensure that areas are kept free from smoke and allow for safer evacuation routes or fire-fighting operations. In contrast, the standardization of airflow across all situations is not a primary function or requirement of smoke dampers, as their operation is specifically designed to respond to hazardous conditions rather than maintaining a consistent airflow. Routine maintenance checks may indeed require access to dampers, but manual overrides during these checks are not typically necessary; adjustments are usually made in a controlled environment. Enhancing system efficiency is not the main purpose of a manual override either; instead, the focus is on safety and effective response during emergencies.
