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

INSTALLATION VIDEO

FIRE BATT INSTALLATION OF TROX RECTANGULAR FIRE DAMPERS

In the past, openings for the installation of fire dampers in solid walls or ceiling slabs had to be of the exact size; only minimal tolerances were allowed, if at all. This has changed with fire batt solutions as they provide a new level of flexibility. With a fire batt, fire dampers can in fact be installed in openings that are much larger than the fire damper casing – the perimeter gap may be up to 400 mm wide. It is no longer a strict requirement that an installation opening fits the fire damper exactly.
