APPLICATION

UL Fire Rated Floor/Ceiling Assemblies and
Roof/Ceiling Assemblies require specially tested and
classified Ceiling Dampers (also called Ceiling Fire
Dampers or Radiation Dampers) to provide fire and
heat protection where HVAC components penetrate
the ceiling membrane. Standard, 1-1/2 and 3 hour
primary fire dampers DO NOT provide the necessary
protection.

Carnes model VXCBQD is UL Classified to provide
protection of ceiling openings in fire rated floor/ceiling
assemblies with fire resistance ratings of 3 hours or
less.
