Additional Notes
The 53CVS is UL/ULC certified for use as a 3-hour static fire damper in HVAC systems.
The 53CVS is designed for installation in vertical fire-rated wall and floor assemblies using square or rectangular ductwork, where the HVAC system fans shut down automatically on fire alarm activation. The 3-hour fire rating makes it suitable for fire separations requiring a higher level of protection than the 1-1/2 hour 51-series dampers, including fire walls and high fire resistance rated assemblies up to 4 hours. The Type C configuration locates the blades entirely outside of the duct airflow path, minimizing airflow resistance during normal system operation. The interlocking curtain blade closes under spring tension when the fusible link releases.
