DTR / DTR B swing-door drives

Accessibility and comfort even for noise-sensitive areas

Automatic closing is desirable with fire and smoke protection doors. However, a closed door always represents an obstruction. Nevertheless, convenience and accessibility can only be ensured if the door is easy to open. Automatic swing-door drives from the GU Group ensure secure closure yet allow convenient access via the radar motion sensor, push-button or access control system. Entrance doors in the facade can also make use of the benefits of the swing-door drive: when combined with multi-point locking, burglar protection and escape route safety are equally possible as well as ensuring accessibility.


High-performance on standard and fire protection doors


The electromechanical swing-door drive DTR is suitable for use on outside doors in facades and on inside doors made from aluminium,
timber or steel – as well as for subsequent automation. It is also especially quiet, and in terms of accessibility this makes it ideal for use in areas that are particularly sensitive to noise. High-performance on standard and fire protection doors. Both drive variants are available either with pull-open or pushopen slide rail or with push-open scissor-action arm. The double-leaf version is also equipped with integrated mechanical closing sequence control. The drives are type-tested by TÜV according to DIN 18650/EN 16005 and approved for use on fire protection doors by DIBt (German Institute of Building Technology) (DTR B).
