What position must a fire damper be returned to after a periodic test, according to NFPA requirements?

• A. Closed
• B. Partially Open
• C. Full-Open
• D. Full-Closed

Answer: (C)

The correct answer is that a fire damper must be returned to the full-open position after a periodic test. This is in accordance with NFPA requirements. Fire dampers are designed to close automatically in the event of a fire, thereby preventing the spread of smoke and flames through the air distribution system. However, during testing and maintenance, it is essential to ensure they function correctly. Upon completing a test, returning the damper to the full-open position ensures that normal air circulation resumes immediately, which is critical for maintaining the proper function of the HVAC system in non-emergency conditions. Testing in this manner helps to confirm that the damper will operate correctly when needed, while also allowing the HVAC system to function efficiently when there are no fire hazards present. Regular inspection and testing are vital to ensure the reliability and effectiveness of the fire damper system in protecting life and property.
