Specification Sheet - Many codes require that exhaust fans installed in multi-family fire-rated ceilings must be Protected by dampers, which, in case of fire, Protect against the spread of heat and flame. Broan offers a variety of radiation/fire damper solutions to meet most any need. When the air temperature passing through the damper exceeds 165F the fusible link melts, triggering the thermal fabric to automatically close across the damper. Airflow is interrupted by a flame and heat barrier, preventing the rapid spread of fire to other areas.
