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

TECHNICAL INFORMATION



Function, Technical data, Quick sizing, Specification text, Order code

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 (C ) 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.

Quick sizing tables provide a good overview of the volume flow rates for different airflow velocities as well as of differential pressures

The differential pressures shown apply to smoke control dampers without a cover grille, installation type C

Differential pressures for smoke control dampers with a cover grille or for other installation types can be calculated with a correction factor

Precise values based on project-specific data can be determined with our Easy Product Finder design software
