Many codes require that exhaust fans installed in multifamily firerated ceilings must be protected by dampers, which, in case of fire, protect against the spread of heat and flame. When the air temperature passing through the damper exceeds 165anddeg,F 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.
