Smoke damper for pressure differential type smoke control systems

PRIORIT Smoke control dampers for use in pressure differential type smoke control systems (RDA) – to EN 12101-8

Smoke displacement through excess pressure

The escape route from a floor does not begin at the stairwell. The zone protected by excess pressure should extend as far as possible in the direction of the used facility. Therefore, an air flow against the direction of smoke propagation is necessary. Smoke is displaced from the escape route and in the best possible case led outside of the building.To ensure airflow between stairwell and hallway or corridor with open doors lock on the fire floor, it may not come to a surge.Leaks in the building envelope and/or facade are ignored in the design, since they are not defined. Therefore, other exhaust possibilities must be created on the floors.Preferably, these exhaust openings are realized in a shaft in the interior of the building. In case exhaust openings are installed in the facade of a building, the influence of wind in case of fire (luv/lee) must be taken into account. 

 

Advantage

Differential pressure systems (RDA) are the optimum technique to ensure smoke-free escape routes for the benefit of residents and emergency workers.

Large-sized smoke dampers according to EN12101-8 as a closure for smoke extraction openings for smoke protection pressure systems with CE certificate (new BauPVO)

PRIORIT exit closure PRIODOOR ETX RDA has passed the fire test for smoke protection dampers in accordance with DIN EN 1366-10. Thus smoke protection pressure systems can now be designed with almost any exit surface area size without disturbing the overall appearance of corridors and galleries. For all PRIODOOR ETX RDA exit closures are manufactured with decorative surfaces from material classified as non-combustible. In case of fire they automatically open into the discharge ventilation shaft.


The new feature of the PRIORIT smoke exit closures are the big exit surface areas, which can be very cost-effectively and appealingly integrated into buildings. Thanks to the flush construction even nearly invisible exit closures can be successfully implemented.


The exit closures are suitable for smoke protection pressure systems according to DIN EN 12101 as they are used in internal safety stairwells. During regular operation, the covers are closed flush in the block frame and ensure a tight seal. Only in case of fire and exhaust opening opens on the floor with the fire for discharging hazardous fire gases. It is operated by a smoke protection pressure system. The installation minimizes the spread of smoke in areas and floors with fire and increases the safety in the building.

      Exit closures can be installed in existing ducts or by using the PRIOWALL wall system. Thus, even entire ducts with side walls and top panels can be produced in a uniform design.

      NEW: PRIODOOR ETX RDA H –
      Smoke damper, horizontal 

      Large format, single leaf, fire resistant smoke control damper especially designed for installation in air release shafts of RDA (RDA = Smoke protection pressure systems). In case of fire the smoke control damper is opened automatically by the controls of the on-site RDA. Large-format cross-sections provide a clear, unobstructed air release area for fire gases. The closure is smoke-tight and provides fire resistance for 90 minutes.

      PRIODOOR ETX RDA – Smoke damper, vertical 

      Large-size, single-vent, fire resistant, specially designed for installation in RDA outlet ducts (RDA = Fire protection pressure systems). When a fire occurs, the exhaust damper is automatically opened by the control unit of the RDA supplied by the customer. Large-size cross sections offer a free unhindered outlet surface area for combustion gases. The closure is smoke-proof and offers fire resistance for up to 90 minutes.


      The exit closures are suitable for smoke protection pressure systems according to DIN EN 12101 as they are used in internal safety stairwells. During regular operation, the covers are closed flush in the block frame and ensure a tight seal. Only in case of fire and exhaust opening opens on the floor with the fire for discharging hazardous fire gases. It is operated by a smoke protection pressure system. The installation minimizes the spread of smoke in areas and floors with fire and increases the safety in the building.
