Standards and guidelines

  • Construction Products Regulation
  • EN 15650:2010 Ventilation for buildings – Fire dampers
  • EN 1366-2:1999 Fire resistance tests for service installations – Fire dampers
  • EN 13501-3:2010 Fire classification of construction products and building elements
  • EN 1751:1999 Ventilation for buildings – Air terminal devices

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 a spring return 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

Construction with fusible link

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. In the event of a fire, the damper is triggered at 72 °C or at 95 °C (use in warm air ventilation systems) by a fusible link. The release mechanism is accessible and can be tested from the outside. Both regular limit switches and explosion-proof limit switches are available for zones 1 and 2 (gases, mists, vapours) and for zones 21 and 22 (dusts) to indicate damper blade positions.

Construction with spring return actuator

Functional description

The fire damper is used as a shut-off device to prevent fire and smoke from spreading through ducting in areas with potentially explosive atmospheres. The fire damper is suitable for supply air and extract air systems in potentially explosive atmospheres. For the operation of the fire damper, the operating and installation manual and the technical data in the supplementary operating manual must be observed.
