Standards and guidelines

• DIN 4102-6, standard fire resistance test
• EN 1751 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
