@randahl Overhere the sirenes are tested on a monthly base. When replacing the old mechanical sirenes the plan was to start testing the sirenes in a silent way. This was 15 years ago. There was immediately a discussion about that (stupid) plan and we continued with monthly testing like it was done earlier.
Now the sirenes have to be replaced again and there was a discussion whether we should switch over to warning messages on mobile phone. Thanks to Putin we are getting new sirenes.
