Warema‘s new early warning system SenSigna records and evaluates every movement by an external venetian blind. If it moves differently than when used as normal or affected by the weather, SenSigna sounds the alarm at around 90 dB, driving away potential trespassers before they can damage the window. SenSigna can be added on to all common external venetian blind systems and slat geometries without any additional planning. On site, it can be integrated inconspicuously into a recess in the bottom rail that is prepared during manufacture, securing it against sabotage. It also comes with its own power supply, making it suitable for retrofitting. The acoustic signal is emitted via an integrated loudspeaker.
If the external venetian blind encounters an obstacle when lowered, a signal is emitted at a reduced volume.
