Fast and safe: Active Crash System EFA-ACS

Especially with regard to extremely high speed, safety is a big issue. Best protection is offered by the Active Crash System, by means of which the door leaf repairs itself. EFA-ACS, the completely new crash protection provides a fully-automatic, electronically monitored retraction of the door leaf after a crash.

This is how the Active Crash System works

In case of a collision, the demountably connected laths can be pressed out of the guide without being damaged. This is recognised by an inductive sensor system which joins the inner and the outer hinges of the door leaf again in a safe and correct manner during a slower upwards movement.
