new: DTN 80

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.

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.

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.
