Integrated safety
To permit a safe passage between closing doors, the doors reverse immediately if an obstruction
is detected. They then resume their interrupted movement at low speed to check whether the
obstruction has disappeared or not.
If an obstruction is detected between opening doors and surrounding walls or interior fittings,
the doors stop immediately, and then close after a time delay.
Safety system with presence sensors
Usually the safety system incorporates presence sensors installed above the door opening. A
presence sensor detects an object in the doorway, while the doors are closing, the doors reverse
immediately. They then resume their interrupted movement as soon as the object is removed.
