What must be completed before conducting the operation test for a combination fire/smoke damper?

• A. HVAC installation
• B. HVAC balancing
• C. Fire alarm testing
• D. Electrical safety inspection

Answer: (B)

The requirement for HVAC balancing to be completed before conducting the operation test for a combination fire/smoke damper is rooted in ensuring that the system operates within its designed parameters. When HVAC balancing is done, it ensures that air flows are correctly adjusted throughout the system. This is crucial because proper airflow is necessary for combination fire/smoke dampers to function as intended during an emergency situation. If the balancing is not completed, the damper may not fully or properly close, or it may not open when required, compromising the system's ability to control smoke and heat effectively. Thus, completing HVAC balancing prior to the operational test guarantees that the damper is tested under realistic conditions, leading to a more accurate assessment of its performance.
