Product description

CEILING RADIATION / FIRE DAMPERS as described are installed to protect the penetrations in the ceiling membrane portions of Fire rated Floor/Ceiling or Roof / Ceiling assemblies, as a shield against fire and heat radiation

The Model 5691 Ceiling Radiation / Fire Damper is test proven for 2 hours in a 120/120/120 Boral Fire Rated Ceiling system, and certified for 1 and 1½ hour ceiling systems. The damper capabilities MUST cover three important areas, Flame, Heat and Smoke:

a) STOP FLAMES and combustible materials from entering the duct above, and spreading throughout the building
b) REDUCE RADIANT HEAT which could ignite materials above the fire rated ceiling, and
c) REDUCE the transfer of SMOKE and dangerous HOT GASES from the fire zone to the non-fire zone
