At 11 a.m. sharp, around 90 sirens are switched on in the district: The "one minute wail" signal means in an emergency: there is imminent danger in the area or danger is expected shortly. Use all possible information media for further instructions, these are broadcast by all local and regional radio stations. Follow the official instructions." Immediately afterwards, the sirens are switched on again with the signal "One minute continuous tone", which means: "There is no longer any acute danger. Use all possible information media to obtain further information."
As the responsible local police authorities, the towns and municipalities can warn their population by triggering the local sirens. If several municipalities are affected or even the entire district, the alarm is triggered via the integrated control center of the Ludwigsburg district (ILS).
However, some towns and municipalities in the district no longer have sirens: Ludwigsburg, Kornwestheim, Remseck, Korntal-Münchingen, Marbach, Vaihingen, Ditzingen, Freiberg and Oberstenfeld (except Gronau and Prevorst) as well as the districts of Bissingen and Untermberg in the town of Bietigheim-Bissingen. Eberdingen is not connected to the general disaster alarm network with its sirens, but can only use them for local fire department alarms.
In towns and municipalities that no longer have sirens or are not connected to the general disaster alert network, the population is warned in an emergency by loudspeaker vans and also via the federal government's NINA warning app (emergency information and news app).
