Maintenance
Smoke control dampers must be operational at all times and must be maintained regularly so that they provide the required services.
Maintenance is required at least every 6 months
A maintenance report must be created; documents must be kept for reference
The functional reliability of the smoke control damper must be tested at least every six months; this has to be arranged by the owner of the smoke extract 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.
Depending on where dampers are installed, country-specific regulations may apply.
For details on maintenance and inspection refer to the installation and operating manual
