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 VXCBQE is UL Classified to provide
protection to HVAC penetrations larger than 324 sq. in.
and up to 576 sq. in. through UL fire rated assemblies
with fire resistance ratings of 3 hours or less. The
quantity and frequency of permissible HVAC ceiling
penetrations are described in the UL Fire Resistance
Directory.
