Standards and guidelines

• Complies with the European product standard DIN EN 12101-8 Smoke and heat control - Smoke control dampers
• Is classified according to DIN EN 13501-4 Fire classification of construction products and building elements
• Fire protection tested in accordance with DIN EN 1366-2 and DIN 1366-10 Fire resistance tests for installations - smoke control dampers
• DIN EN 1751 Ventilation for buildings – Air terminal devices

Maintenance

• Smoke control dampers must be operational at all times and must be maintained regularly so that they meet the performance requirements.
• Maintenance at least once every six months; maintenance must be recorded; documents must be kept for reference.
• The owner of the smoke extract system must arrange for a functional check of the smoke control damper every six months. For this purposes, follow the basic maintenance specifications according to DIN EN 13306 in conjunction with DIN 31051. If two consecutive tests at intervals of 6 months do not reveal any functional defects, the smoke control damper only needs to be checked once a year.
• Depending on the installation location, country-specific regulations may apply.
• For details on maintenance and inspection, please refer to the installation and operating manual.
