Siren test in Bremen: test alarm for more safety on Saturday!
Today, October 4th, 2025, the sirens will sound at 12 p.m. in Bremen for the popular test alarm. Results show that this alarm occurs on the first Saturday of every month to alert the population to possible dangers. A total of 18 sirens are in operation in Bremen, while Bremerhaven carries out its test alarm every third Saturday of the month. How buten and within reports, it is important to carry out these regular tests to ensure the sirens are working properly.
But what is behind these alarms? The test alarm is primarily used to regularly test the sirens and other warning systems. Such exercises were found to be crucial in increasing the public's preparedness in the event of an emergency.
Nationwide Warning Day: An important date
The next nationwide warning day will take place on September 12th. On this day, a test warning will be triggered via the modular warning system (MoWaS) from 11:00 a.m. This campaign is intended to test the warning systems via various channels. How bbk.bund.de explains, the warning text is distributed to numerous warning multipliers such as broadcast stations and app servers. This means that all major media outlets as well as the public receive time-delayed information about a possible danger.
In many districts and municipalities, municipal warning channels are also used, such as the use of loudspeaker trucks or the activation of sirens. The all-clear will then be given at around 11:45 a.m. via the same channels in order to inform people in good time. However, no all-clear signal is currently being sent via the Cell Broadcast service. However, mobile phone providers are working to offer this feature as soon as possible.
The role of the NINA app
Another important component of the warning is the federal government's NINA app. This app offers the opportunity to receive important civil protection warnings directly on mobile devices. As the Federal Government reports, the app is available for download in common app stores and allows users to quickly have important information at hand in an emergency.
It is very important that these warning systems work well and that the population is trained accordingly. The advertising tests and the use of modern technologies such as the NINA app show that civil protection in Germany is being continuously improved. So be warned and ready - especially now when the sirens sound again!
