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 for the ventilation system
▪ For details on functional tests, maintenance and inspection refer to the installation and operating manual

The ready-to-use units contain a release mechanism and an interchangeable, fire-resistant damper blade that can be arranged horizontally or vertically depending on the use. Depending on application, classified from

EI 30 (ve, ho i ↔ o) S to EI 120 (ve, ho i ↔ o) S.
