Supply package

If attachments and accessories are supplied from the factory with the fire dampers, they are already taken into account in the order code. Depending on the installation situation, supplementary materials for assembly and fixing may be needed to ensure proper installation, e.g. mortar, screws, mineral wool, etc. Such materials are not included in the supply package, unless they are expressly described as included in the supply package. The selection of additional attachments or accessories as well as the identification and provision of materials for assembly and fixing is the responsibility of those involved in the building project and must be done taking into account the required classification.

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 2 consecutive tests, one 6 months after the other, are successful, the next test on the fire damper 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

If fire dampers with a purely mechanical shut-off element are to be used as an upstream shutter of an air transfer unit, the local building regulations must be observed. This may require building authority approvals. This must be checked and applied for by others. Usually the use of such upstream shutters of air transfer units is restricted to pressure differential systems.
