On Thursday, 10 September, the National Warning Day will take place, in which the city of Chemnitz will once again be participating. At 11.00 am, a test warning will be triggered centrally via the National Warning Centre in Bonn using the Modular Warning System (MoWaS). This will appear, for example, in the NINA warning app, via the Cell Broadcast mobile service, or on digital city information screens.
In Chemnitz, the ‘Danger Warning’ tone (a one-minute wailing tone, i.e. six tones, each lasting five seconds, with a five-second pause between them) will be heard from the sirens at all locations and at the majority of CVAG bus stops, though without a gong or a voice announcement. The planned text for the display boards is: ‘National Warning Day 2026 – Test alert’. At 11.45 am, the all-clear will be given: the all-clear warning tone (a continuous one-minute tone) will sound and the text ‘All-clear: National Warning Day 2026’ will be displayed.
