  • Page 2 These technical specifications state a row of manufactured sizes and models of fire dampers (further only dampers) FDMA. It is valid for production, designing, ordering, delivery, assembly and operation. 1. Description......................... 2. Design..........................3. Communication and control devices..................15 4. Dimensions, weights......................18 5.
  • Page 3 Fire dampers are shutters in ducts of air-conditioning devices that prevent spreading the fire and combustion products from one fire segment to the other one by means of closing the duct in the points of fire separating constructions. Dampers blade automatically closes air duct using a shutting spring or an actuating mechanism back spring.
  • Page 4 Working conditions Right damper function is secured under the following conditions: a) Maximum air circulation speed: 12 m.s Maximum pressure difference: 1200 Pa b) The air circulation in the whole damper section must be secured as steady on whole surface. Operation of the dampers does not depend on the direction of air circulation.
