In brief: Eine Hochschiebesicherung verhindert, dass ein geschlossener Rollladen von außen hochgedrückt wird. Sie verbindet den Panzer fest mit der Welle, sodass er im unteren Bereich nicht nachgibt. Ein Rohrmotor allein ist kein Einbruchschutz, hält den Panzer aber über seine Bremse in Position.
How does the device work?
- Rigid shaft connectors instead of suspension springs: they firmly couple the top slats to the shaft.
- Motor brake: tubular motors have a brake that holds the shaft when stationary.
- Together, the curtain can hardly be pushed up.
Retrofitting
- Choose shaft connectors to suit the shaft and slat profile.
- Then check and if necessary readjust the end positions – the curtain must not press too hard on the windowsill.
- With belt winders, motorise first: Replacing a belt winder with a roller shutter motor.
Motor with obstacle detection
Electronic motors such as the A-OK AM45 radio stop on resistance. This protects the curtain and connectors when the roller shutter hits an obstacle.
Frequently asked questions
Is an electric roller shutter more secure than a belt-operated one?
Somewhat, because the motor brake holds the shaft. Real anti-lift protection also needs rigid connectors.
Does the device work with radio motors?
Yes. The device is mechanical and independent of the operation.
