摘要

The roller shutter for a building door or window has a panel with louvres (3,4) and an integral sensor (8) for break in attempts, connected to the shutter drive and an alarm (11). The sensor can be connected to the drive and alarm via a radio connection. One of the louvres can be aluminum, with at least one slot (12) positioned as a function of the wavelength to act as an antenna.
