Test Conclusions:
The FSD-C fire/smoke damper satisfied the requirements of BS EN
1366-2 and BS EN 13501-3 achieving the lowest closed blade
leakage of any damper within its class.
Dampers were tested affixed to the inside of the furnace wall and
also to the external wall of the furnace with the damper closed
blade being fully exposed to the furnace rapid rising temperature.
The achieved ES classification ensures that in a fire condition the
non fire side is fully protected (from radiated heat) for the
achieved period, providing vital time for the emergency services to
respond, ensuring safe passage of escape and protection of
contents
