  • Page 2: Table Of Contents

    These Technical Specifications define the range of the manufactured sizes and models, the main dimensions and the scope of use of the FDMR 60 fire dampers (hereinafter referred to only as the "fire dampers"). They are binding for production, designing, ordering, delivery, storage, assembly, operation, maintenance and operability inspections.
  • 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. The damper blade automatically closes the air duct using a shutting spring or an actuating mechanism of back spring.
  • Page 4 Design with mechanical control Design with mechanical control with a thermal protective fuse which actuates the shutting device, after the nominal start temperature 72°C has been reached. Automatic initiation of the shutting device is not activated if the temperature does not exceed 70°C. In case that other start temperatures are required, thermal fuses with nominal start temperature +104°C or +147°C can be supplied (this requirement must be specified in the order).

    Fire dampers can be suspended by using threaded rods and a mounting profiles. Load the suspension system depend on weight of the fire damper. Damper assembly procedures must be done so as all load transfer from the fire separating constructions to the damper body is absolutely excluded. Back-to-back air-conditioning piping must be hung or supported so as all load transfer from the back-to-back piping to the damper is absolutely excluded.

  • Page 41: 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 42 Sizes are checked by common measuring instruments according to the standard of non-tolerated sizes, used in air conditioning industry. Interoperational checks of components and main sizes are carried out according to drawing documentation. After workshop installation, a 100% check of function of closing mechanism and electric compo- nents is carried out.
  • Page 43 The assembly of the dampers must be carried out while observing all applicable safety standards and regulations. All flange and screw joints must be conductively connected during the assembly to provide protection against dangerous contact. 2 fan-shaped washers in galvanized version are to be used for conductive connection;...
  • Page 44 Before putting the dampers into operation and during subsequent function checks, the following checks must be carried out for all designs: Visual check of correct installation of the damper, of the damper interior, of the damper blade, of the seating faces of the blade and of the silicone seal. Disassembly of inspection hole cover: Remove the button-headed screws (2) and tilt the cover to take it out.

  • Page 45: Spare Parts

    Spare parts are supplied only on basis of an order. If tripping of the thermal fuse Tf1 occurs (due to temperature around the fire damper), the actuating mechanism including the thermoelectric starting mechanism must be changed. If tripping of the thermal fuse Tf2 occurs (due to temperature inside the piping), the self-standing spare part ZBAT72 or ZBAT95, respectively (according to actuating temperature), must be changed.
