Broan Nutone Radiation Damper Accessory

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. When the air temperature passing through the damper exceeds 165-degreesF 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.
