As soon as it gets dark, press the switch, or use your remote control – and your roller shutters, will reliably move down into the closed position. Or alternatively, use a timer or a smart home solution.
If your roller shutter encounters an obstacle, it will automatically stop in good time before any damage is caused to either the object or the roller shutter. This is taken care of by the sensitive obstruction detection system in your Becker drives.
And you can feel just as relaxed when it starts getting late. You can rest assured that your roller shutters will do their job at the very moment for which they have been programmed, thus making life difficult for any potential burglar.
If you are away you can simply program your timer or home automation system to open and close your roller shutters or blinds to disguise your absence.
