Swing door drive DTN 80

High-performance on standard and fire protection doors

Swing-door drives open up new opportunities: automatic opening and closing fire and smoke protection doors as well as interior and exterior doors increase freedom of movement and safety in public buildings. Comfortable access is provided via radar motion sensors, push-buttons or an access control system.
A combination of multi-point lock and motor-driven shoot bolt lock is recommended for entrance doors in the facade. This makes accessibility, burglar protection and escape route safety a reality.


System features

For use and retrofitting universally

The DTN 80 swing-door drive can be used on doors with any frame material. It can be supplied in various surfaces. Automation of existing swing doors is possible at any time by retrofitting the DTN 80.

Burglar protection

Outside doors present special challenges with regard to burglar resistance. The DTN 80 ensures convenient access to entrance areas and can be used on all certified swing doors up to resistance class RC4.

Wind tightness and tightness against driving rain

When used in combination with the DTN 80 swing door drive, certified swing doors satisfy the performance characteristics
described in EN 14351-1 and therefore provide a tight seal

Fire protection and accessibility

The DTN 80 swing-door drive is the perfect solution for barrier freedom at fire protection doors, such as those found in hospitals and residential homes This is because the DTN 80 swing-door drive is able to overcome any spring force that may be present at fire and smoke protection doors in normal mode: in the event of fire, they must be able to close safely purely by means of the spring force.
The DTN 80 thus ensures barrier-free access on a daily basis.

System solutions for escape and rescue routes

Escape and rescue route systems can only offer maximum security if all components are perfectly matched to the requirements of the particular building situation. Isolated solutions are therefore not an option in this case.
The DTN 80 swing-door drive is a compelling product and

satisfies the requirements of the EN 179 and EN 1125 standards
in combination with our tested and approved units consisting
of panic lock and door hardware.


Universal application
All applications can be implemented
using only one swing-door drive:
– 1- and 2-leaf swing doors
– Fire doors
– Escape doors
– Push-open or pull-open

  • For door leaf weights up to 600 kg
  • For door leaf widths up to 1600 mm
  • Patented energy-store consisting of two spring assemblies which can be adjusted separately
  • Closing force instead of latching speed
  • Patented closing damping via the dynamic effect of the drive motor
  • Door closer effect
  • Servo assistance adjustable from 0°
  • 24 V/2.5 A power supply for external components
  • High dynamics and therefore high opening speed
  • Mechanical closing sequence control for 2-leaf fire protection doors or for doors in escape routes concealed under the drive cladding
  • Modular system reduces inventory management
  • Quiet running properties make it particularly suitable for use in noise-sensitive areas, such as offices or hospitals
  • Convenient adjustment options directly at the drive via the rotary knob/push-button with integrated display under the drive cladding
  • Assembly friendly: retaining pins on the camshaft make spring-biased assembly easier
  • Elegant and stable design of scissor-action arm and slide arm
  • Tested quality
    – Type-tested by TÜV and certified to EN 16005
    – Tested by VdS and material testing office in Germany in accordance with DIN 18263-4/EN 1158
    – Design approval by German Institute of Building Engineering (application filed)


Patented double-spring system for high closing force before closing position

Due to challenging building conditions, it is not certain that doors will always be closed by swing-door drives or door closers. This includes draughts, wind, positive pressure in double door systems, or the need to overcome the mechanical resistance of gaskets or multi-point locks

This challenge is particularly noticeable just before the door
engages in the lock. This is namely the point at which the force of the closing spring, which is applied throughout the entire closing operation of typical swing-door drives, is at its weakest.


We have therefore installed two spring assemblies in the DTN 80 swing-door drive, instead of just one. The second acts,
controlled by a cam disc, just before the door reaches the closing position – in other words, exactly at the point where a higher closing force is required.

BS Pictogramm

Extended set of fire protection measures

The swing-door drive becomes the DTN 80-F when combined with the extended set of fire protection measures for DTN 80. Together with a smoke switch and a "CLOSE DOOR" push-button, the DTN 80-F can be used as component of a hold-open system on fire and smoke protection doors.

Closing sequence control set SFR DTN 80

A mechanical closing sequence control is required for use at 2-leaf fire and smoke protection doors. This can be easily mounted on the DTN 80 in just a few steps. The two swing-door drives are connected via a Bowden wire. All components can be found under the drive cover or the cover between swing door
drive covers.
