In many places in Germany, the sirens sounded on December 8, 2022. Of course, our electronic sirens at the HÖRMANN headquarters in Kirchseeon were also present at the nationwide warning day on December 8, 2022. However, the modern electronic sirens can do more than the typical wailing and warning sounds. Sirens are also a means of informing the population, for example by playing recorded voice texts or by means of live announcements.
