Standards and guidelines

• Construction Products Regulation
• EN 12101-8:2011 Smoke and heat control systems – Smoke control dampers
• EN 1366-10:2011 Fire resistance tests for service installations – Smoke control dampers
• EN 1366-2:1999 Fire resistance tests for service installations – Fire dampers

Maintenance

• Mechanical smoke extract systems require that the power supply is maintained even in the event of a fire
• Smoke control dampers must be maintained regularly and must be operational at all times
• 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
• For details on maintenance and inspection refer to the installation and operating manual
