Test alarm in Radeberg: Warning day on September 11th sensitizes the population!

On September 11, 2025 at 11:00 a.m. the time has come: Germany will be at Nationwide warning day tested thoroughly. The aim of the large test alarm is not only to check the technical infrastructure for warnings, but also to identify any weak points in the warning system. This is particularly important in light of the 2021 floods, which tragically showed many people how crucial timely warnings are.

The process is simple and clearly structured: At 11:00 a.m. the warning text is sent via the Modular Warning System (MoWaS) to various warning multipliers, such as radio stations and app servers. They then forward the information to citizens, be it via televisions, radios or smartphones. The existing siren network is also being tested in the Bautzen district - an additional hearing signal for everyone present.

Details about the process

At 11:15 a.m., the local fire protection authorities are also on board: They may make voice announcements to address the population directly. At 11:30 a.m. testing of these announcements will be completed and an all-clear will be sent out at 11:45 a.m. via the same channels through which the warning was issued. An exciting event that all citizens should be aware of.

Especially in Radeberg and the surrounding districts, people listen very carefully, as some siren systems are also active here. As part of the exercise, the signal tone “Warning of danger” is sent and then the “All clear” signal is sent. This is a good opportunity for those involved in Radeberg and the surrounding area to experience first hand how the warning systems work and how they are accessible.

No need to panic

Important to know: The population does not have to prepare specifically for the warning day. Nevertheless, it is advisable to inform friends and family that a test run will be carried out on September 11th. Ultimately, the goal is clear: raise awareness of emergencies and create awareness that warnings should be taken seriously.

The Radeberg press portal emphasizes that this sample can also be considered a stress test for the technical infrastructure that must be ready for future alerts. It's about learning and ensuring that all systems are working optimally so that no time is lost in an emergency.

A comprehensive monitoring network of 38,000 sirens, radio and television stations as well as warning apps has already proven its suitability. That's not all: other technological advances, such as cell broadcasting, are also being examined to ensure that every person in an affected area can be reached in the event of an emergency.
