Maintenance

  • 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

Functional description:

Smoke control dampers are used in mechanical smoke extract systems. They are used for extracting smoke gases and for providing additional supply air to one or more fire compartments. The dampers are made of galvanised sheet steel or stainless steel and are opened by an actuator; when smoke is detected, the actuator is triggered by a signal either from a duct smoke detector or from a fire alarm system. Smoke control dampers have two safe positions: open and closed. In the case of fire-resistant smoke control dampers for multiple compartments, the safe position is either 'open' or 'closed', depending on the fire site and the path of the smoke to be extracted. If the safe position is 'open', the free area must be maintained even in the event of a fire. Regular maintenance of the smoke control damper is required to ensure its functional reliability.

  • Rectangular or square smoke control dampers to product standard EN 12101-8, tested to EN 1366- 10 and EN 1366-2, for use in smoke extract systems. 
  • Smoke control dampers not only prevent the spreading of smoke and combustion products between fire compartments, they also prevent the leakage of emitted, dangerous and poisonous fire suppression gases from the affected area, and they maintain positive pressure in pressurisation systems.
  • The EK-EU is suitable as a pressure relief damper for gas fire extinguishing systems.
  • For extracting smoke gases and for providing additional supply air to one or more fire compartments.
  • The EK-EU can be used in smoke extract systems which have been approved for extract ventilation. The fire-resistant smoke control damper for multiple compartments is suitable for installation in solid walls.
