Fire dampers for circular duct mounting. Dampers designed to maintain the fire resistance of the wall or the floor, in which a passage for ventilation, heating or air conditioning ducts has been made. They have been tested in accordance with the standards EN-1366-2 achieving the fire resistance EIS 120 (Integrity, Insulation and smoke leakage during 120 minutes), to comply with building regulations for fire safety. In case of fire, the damper stops the air passage at 72ºC by means of a fusible link that closes a blade valve. An expanding joint and another one of air tightness, as much prevent the propagation of smoke to high as to low temperature. These dampers full fill the required conditions for the (S) symbol, air-tightness to cold smoke. In case of fire, poisoning by smoke is the main cause of death. Dampers with the displaced mechanism that facilitates a good installation.

FIXING SYSTEMS The damper is fixed in accordance with the figure. The damper cannot be fixed in place when vibrations are occurring. 145 The dampers must be installed in a way that they can be operated manually. Precautions will have to be taken in order to ensure that the air flow reaches the fire damper uniformly. W SPECIFICATION TEXT Supply and mounting of fire damper for circular duct classed EIS-120 in accordance to the European standard EN-1366-2 series FOC-EIS-120-M7F24 D=200. Operated by means of a servomotor at 24v M7F24, start and end of course switches. Dampers made from galvanised...
