  • Page 81: Material

    Damper bodies are supplied in the design made of galvanized plate without any other surface finishing. Damper blades are made of fire resistant asbestos free boards made of mineral fibres. Control devices of dampers has cover from mechanically resistant and standing plastic and rest of the parts is galvanised without further surface treatment.
  • Page 82 The manufacturer provides a warranty of 24 months from the date of dispatch for the dampers. The warranty for fire dampers FDMQ, provided by the manufacturer, shall become completely null and void if the starting, closing and control devices are unprofessionally handled by untrained workers or if electric components, i.e.
  • Page 83 The assembly of the dampers must be carried out while observing all applicable safety standards and regulations. The damper body should not be deformed in the course of bricking in. Once the damper is built in, its blade should not grind on the damper body during opening or closing. All flange and screw joints must be conductively connected during the assembly to provide protection against dangerous contact.
  • Page 84 Before entering the dampers into operation after their assembly and by sequential checks, the following checks must be carried out. Visual inspection of proper damper integration , inside damper area, damper blade, contact surfaces and silicon sealing. Check of thermal protective fuse and closing mechanism.

    For the designs with actuating mechanisms, the following checks must be carried out: Check the shift of the blade to "CLOSED" failure position after cutting off the power supply to the actuating mechanism (e.g. by pressing the reset button on the thermoelectric starting mechanism BAT, by cutting off the power supply from electrical fire signalization).
