Prede alarm in Pinneberg: all -clear after successful test!
On October 5, 2025, the sirens heralded in Germany, and not without reason. In Pinneberg, the annual warning day was on the agenda, in which the functionality of sirens and warning systems was tested. The event was used for disaster prevention and ensuring that in an emergency the population can be warned in good time. The first test signals were triggered nationwide at 11:00 a.m. and various warning apps, including the well-known Biwapp, were used to inform people.
Biwapp, which stands for “citizen information and warning app”, is a free smartphone app that supports citizens in emergency and crisis situations. With the help of this app, users can receive current information and disaster reports for your region. The app is individually customizable, so that users can be specifically informed about relevant topics such as school failures or fire. The all -clear was also published in Pinneberg via Biwapp after the original warning included the recommendations to avoid the affected area and to find out more in the media. All associated measures were thus canceled.
Uniform warning systems for security
The warning day has established itself as an important date in the calendars of the German cities. Siren and cell phones were used not only in Pinneberg, but also in other parts of the country to warn the population. While the Deutsche Bahn and local transport companies were involved in the day, the warning day 2025 presented itself as smooth and effective, which was supported in particular by the experience from the previous years.
The modular warning system (Mowas) controls around 8,700 city information boards in Germany to provide quick information in the event of a disaster. The aim of the warning day is to put the existing warning channels through its paces - alternative alarm paths such as speaker cars are also tested. Uniform siren signals are important to create clarity; For example, the on and decongestant howling tone signals a warning, while a howling last tone shows the end of the alarm.
Technological advances
This year there was also an innovation: Technology Automatic Safety Alert (ASA) for DAB+devices. This also recognizes a failure of mobile networks and the Internet, which automatically react to warning messages. A great development that could prove to be extremely valuable in an emergency.
Today has shown how important it is to be well informed in crisis situations. Despite its regional focus, the Biwapp app has played a key role and proved that digital solutions can act hand in hand with traditional warning systems. It is to be hoped that the positive record of this year's warning day will help to further raise awareness of the need for the need for civil protection and citizen information.
The Biwapp here is available free of charge for everyone who wants to keep themselves up to date on the warning and other important information.
