  • EN 13501-4 Fire classification of construction products and building elements using data from fire resistance tests
  • 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 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 of the smoke control damper 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.

Type EK-JS smoke control dampers are tested according to EN12101-8 and EN 1366-10. In rectangular steel and stainless steel construction. Intended for the discharge of smoke and heat in smoke extract systems and for the flow of necessary supply air into the area from which smoke is to be extracted. EK-JS is intended for use in pressurised ventilation systems (DBA) in order to keep safety stairwells and their anterooms and fire brigade lift shafts or escape tunnels smoke-free. They thus enable the controlled discharge of released smoke. EK-JS is intended for use in single sections and may be used at elevated operating temperatures of up to 600 °C on and in horizontally and vertically aligned smoke extract ducts according to EN 12101-7, tested according to EN 1366-9. EK-JS can be used in combined systems (combination damper) for ventilation and is suitable for restricting extract air volume flows. The OPEN-CLOSE actuators can be signalled either with ready-wired actuator control modules or with bus modules.
