Round fire dampers FDA2-12-M with access door and actuator
The FDA2-12 round fire dampers are designed for use in general ventilation systems to seal off smoke and fire between adjacent fire partitions. The fire dampers are classified according to EN 13501-3+A1:2010P (Fire classification of construction products and building elements). The fire resistance was tested as per PN-EN 1366- 2:2015 (Fire resistance tests for service installations — Part 2: Fire dampers). The entire manufacturing process meets the requirements of EN 15650:2010. The FDA2-12 fire dampers can be installed in horizontal and vertical fire partitions to provide fire resistance of EI 120 (ve ho i↔o) S (which may depend on the actual fire resistance of the partition).
The fire dampers are available in the nominal diameter sizes DN200, DN224, DN250, DN280, DN300, DN315, DN355, DN400, DN450, DN500, DN560, DN600, DN630. All fire dampers have a torsion spring trip (in FDA2-12-T) or a returnspring actuator coupled with a thermal trip (in FDA2-12-M). The spring-action versions can be provided with optional limit switches. The casing and optional accessories are made from galvanized steel sheet; the fire damper blade is made from silicate cement board.
Round fire dampers are designed for installation in general ventilation systems. When integrated into fire partitions, they provide equivalent protective performance and features as the partitions. The fire damper blade remains open under normal operating conditions. It is closed shut automatically in the event of a fire.
The fire dampers can be installed in the following partitions:
– concrete separating floor
– concrete wall
– solid brick wall
– cellular concrete unit wall- gypsum board wall on steel frame
