Specifications
Smoke control dampers SEDM-2D (hereinafter named also simply as „the dampers“) are intended to be used in multi compartment smoke control systems in vertical duct (shaft) installations. In normal situation, the dampers remain closed (stand-by position). Upon an activation signal emitted either in the event of a fire, or during a functional test, the dampers of given compartments open in order to allow smoke and heat from the fire to be extracted outside the building. SEDM-2D dampers open to the inside of the duct. The dampers opened during functional testing may be put back to the stand-by (closed) position by hand. The dampers consist of a two calcium-silicate blade reinforced by steel crossbeams hanged on spring-equipped hinges, combined calcium-silicate and galvanized steel body, a cold seal (silicon gasket) and a carbon based thermo-expanded hot seal, electrically activated restraint mechanism equipped by a permanent magnet with an electric coil, optional with end switches, and a metallic grille. The dampers may be installed to the shaft directly using fire-resistant mastic, or using an optional installation frame.
