D+H DDS 54/500
Door opener drive for supply air doors and smoke ventilation systems
In the event of a building fire, smoke has to be extracted at roof level while fresh air must be supplied through openings in the lower part of the building. The DDS 54 opens doors up to 90 degrees with a pressure force of 500 N, while also helping to keep escape routes accessible.
This actuator is intended for single-leaf doors used in smoke ventilation and supply air systems. Its design combines solid pressure force, controlled motion and integration with on-site door release systems.
Performance Features
- For opening single-leaf doors up to 90°
- Motor electronics controlled by microprocessor
- High pressure force due to special chain stabilisation
- Control output for on-site electronic door release
- Provides the required supply air and keeps escape routes open
- The door remains operable by hand
- Can be combined with automatic motor lock, Ikon or Ehem
- Programmable drive functions and adjustable drive parameters
- Additional passive and active anti-trap protection at the main closing edges
- Bracket set included
