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

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 calcium silicate panels and are opened by an encased 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.
The blades of EK-JZ move to the defined safe position upon receiving an automatically or manually triggered control signal. According to the specified time-temperature curve, an EK-JZ can still fully open or close after 25 minutes (MA, manual release).
Similarly, position changes for modulation applications (Cmod) and thus pneumatic volume flow rate balancing via the section of intermediate positions of the damper blade section are possible with the product type EK-JZ.
Regular maintenance of the smoke control damper is required to ensure its functional reliability.

Specification text

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 are not only used for the exhaust of smoke, heat and combustion products, but also for the controlled removal of dangerous and toxic fire suppression gases.
EK-JZ smoke control dampers can also be used in pressurisation systems and as pressure relief dampers in gas fire extinguishing systems. Also for extracting smoke gases and for providing additional supply air for the natural or mechanical smoke extract to one or more fire compartments and in all listed systems of the same type that need to fulfil modulation applications.
EK-JZ can be used in combined smoke exhaust systems which have been approved for controlled ventilation. The fire-resistant smoke control damper for multiple compartments is suitable for installation in and on fire-resistant smoke extract ducts or smoke extract shafts and in fire-resistant standard supporting constructions. It is controlled with open/close actuators that can be combined with control modules that are factory wired and fitted inside the temperature-resistant actuator encasing.
