  • 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

  • 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
