Maintenance

Smoke control dampers must be ready for operation at all times
Regularly maintain smoke control dampers (at least every six months, unless otherwise specified)
A maintenance report must be created; documents must be kept for reference
The owner of the smoke extract system must arrange for a functional check of the smoke control damper every six months. For this purposes, follow the basic maintenance specifications according to DIN EN 13306 in conjunction with DIN 31051. If 2 consecutive tests at intervals of 6 months do not reveal any functional defects, the smoke control damper only needs to be checked once a year
Depending on the installation location, country-specific regulations may apply.

Smoke control dampers are used in mechanical smoke extract systems. They are used for extracting flue gases and for providing additional supply air to single or multiple fire compartments. In the event of an incident, the smoke control dampers are opened or closed manually or automatically by an actuator. The actuator can be encased or not encased. The trigger signal is given either by a smoke detection device (e.g. duct smoke detector) or by a fire alarm system. Smoke control dampers have two safety positions: fully open and fully closed. In the case of fire-resistant smoke control dampers for multiple compartments, the safety position is either 'open' or 'closed', depending on the fire site and the path of the smoke to be extracted. If the position is 'open', the free cross-sectional area must be maintained even in the event of a fire. EK2-EU moves to the desired safety position after an automatic or manual control signal. A change in position is possible up to 25 minutes at a temperature load in accordance with the ISO standard fire curve (MA, manual activation). Position changes are also possible for modulation applications (Cmod) and thus pneumatic adjustment by approaching intermediate positions of the damper blade. Regular maintenance of the smoke control damper is necessary to ensure the required function.

A life cycle assessment is available for the product type in form of an Environmental Product Declaration (EPD) that has been checked and published by an EPD programme operator.

Smoke control dampers in accordance with product standard DIN EN 12101-8, tested according to DIN EN 1366-10 and DIN EN 1366-2, in square or rectangular design for use in smoke extract systems. Smoke control dampers are used to prevent the transfer of smoke and combustion products from a fire area. In addition, smoke control dampers prevent the escape of released, hazardous and toxic extinguishing gases from the affected area and control pressure ventilation and venting devices in pressurisation systems. The EK2-EU is suitable as a pressure relief damper for gas extinguishing systems. For extracting smoke gases and for providing additional supply air to single or multiple fire compartments. The EK2-EU can be used in smoke extract systems that have been approved for ventilation. The fireresistant smoke control damper for multiple compartments is suitable for installation in solid walls and shafts, lightweight partition walls and ceilings, as well as in and on fire-resistant smoke extract ducts. Open-Close actuator, optionally with fully wired and ready-to-operate bus control module inside the temperature-resistant actuator encasing.
