Germany's National Alert Day Sounds Off: Sirens Blast on September 11, 2025 at 11 a.m.

On the upcoming Nationwide Warning Day, the Federal Office for Civil Protection and Disaster Assistance will trigger all available warning means nationwide at 11 a.m., including warning apps, radio broadcasts, and over 120 sirens. This nationwide exercise aims to test technical warning infrastructure and familiarize citizens and the media with the topic of warning.

Cities and municipalities across the country are taking various measures to ensure effective communication during emergencies. For instance, Freiberg am Neckar is installing sirens, and they are expected to be operational for the Nationwide Warning Day. However, some cities and municipalities, such as Ludwigsburg, Korntal-Münchingen, Marbach am Neckar, and Vaihingen an der Enz, do not have sirens or are not connected to the general disaster alarm network. In such cases, these cities will use alternative methods like loudspeaker vehicles, the NINA warning app, and Cell Broadcast for emergency warnings.

Cell Broadcast is a service that can send warnings to all mobile devices in a specific section of the mobile network. To receive these warnings, mobile devices must be switched on and not in flight mode. The Cell Broadcast service will send a test warning message this year on the Nationwide Warning Day. It's important to note that no all-clear messages are sent via Cell Broadcast.

The responsibility for activating the Cell Broadcast service on the Nationwide Warning Day lies with the mobile network operators who send the warning messages directly to citizens' phones using Cell Broadcast technology, coordinated by the Federal Office for Civil Protection and Disaster Assistance (BBK) during the nationwide exercise.

The warning signal "one minute of wailing" means there is an immediate danger in the area or one can be expected soon. On the contrary, the all-clear signal "one minute of steady tone" means there is no longer an acute danger.

It's crucial for everyone to understand warning paths and procedures to ensure safety during emergencies. A test warning message will be sent via Cell Broadcast again on the warning day, providing an opportunity for everyone to test their preparedness.

In addition, Eberdingen is not connected to the general disaster alarm network but can only use its sirens for local fire alarm. It's essential for all cities and municipalities to have effective warning systems in place to ensure the safety of their residents.

By participating in the Nationwide Warning Day, Germany is taking significant steps towards enhancing its emergency response capabilities and ensuring the safety of its citizens.
