PC-RD05C3 - Ceiling Radiation Damper
Local fire codes may require a ventilation fan installed in a fire rated floor/ceiling or a roof/ceiling assembly to be equipped with a specially tested and classified radiation damper. In case of a fire, the radiation damper closes to prevent the spread of fire and heat. Panasonic radiation dampers are designed to protect ceiling penetrations in 1, 2 or 3 hour fire-rated floor/ceiling and roof/ceiling designs.
