Materials and surfaces

Casing:

  • Galvanised sheet steel
  • Stainless steel 1.4301


Damper blade:

  • Special insulation material faced with stainless steel


Other components:

  • Damper blade shafts made of galvanised steel or stainless steel

Standards and guidelines

  • EN 1366-2:1999 Fire resistance tests for service installations – Fire dampers
  • DIN 4102-6, standard fire resistance test
  • EN 1751 Ventilation for buildings – Air terminal devices
  • VDI 2052 Ventilation equipment for kitchens

Maintenance

  • The functional reliability of the fire damper must be tested at least every six months; this has to be arranged by the owner of the ventilation system; functional tests must be carried out in compliance with the basic maintenance principles stated in EN 13306 and DIN 31051. If two consecutive tests, one 6 months after the other, are successful, the next test can be conducted one year later.
  • A functional test involves closing the damper blade and opening it again; with electric blade opening actuator this can be done via remote control
  • Fire dampers must be included in the regular cleaning schedule of the ventilation system.
  • For details on maintenance and inspection refer to the installation and operating manual

Functional description

In the event of a fire, fire dampers shut automatically to prevent the propagation of fire and smoke through ductwork to adjacent designated fire compartments. When in the event of a fire the temperature rises to 72 °C, a capillary tube sensor interrupts the power supply to the electromagnet, and the damper blade is released. While power is being supplied to the electromagnets, the fire damper can be opened with the blade opening lever. The release mechanism is accessible and can be tested from the outside.
