Test alarm in the Heilbronn district: Sirens are wailing, NINA app is being tested!
An important test alarm will take place in the Heilbronn district on June 12, 2025. The aim of the test is to check the functionality of the sirens and the NINA warning app and to raise public awareness of emergencies. The test alarm begins at 11:00 a.m. and lasts for an hour until 12:00 p.m. During this time, sirens will be tested throughout the county.
The test alarm sequence is as follows: At 11:00 a.m., a constant, high-pitched tone sounds for 12 seconds. After a few minutes, the “population warning” signal follows, which can be recognized by a one-minute rising and falling howling sound. At 11:15 a.m. the test will end with another continuous tone that will be heard again for 12 seconds. At the same time, the NINA warning app is also triggered, which provides real-time information about possible dangerous situations, storms and disasters.
Meaning of the test alarm

The police are unlikely to be on duty, which also helps to calm things down.
The NINA warning app enables users to find out about current dangerous situations quickly and easily. This is particularly important because in crisis situations every minute counts. The implementation of such warning systems shows the local government's commitment to maintaining the safety of its citizens.
In summary, it can be said that the test alarm in the Heilbronn district is a sensible measure to strengthen both the technical infrastructure and the knowledge and preparation of the population.
