Sirens and warning systems will be tested between 10 and 11 a.m
On Thursday, March 12, 2026 , Hesse will hold its first statewide warning day of the year. The aim is to test the warning systems and procedures at the state level and in the central control centers.
The nationwide warning day will every year on the second Thursday in March and will complement the nationwide warning day in autumn.
Testing of warning systems throughout Hesse
While the nationwide warning day primarily focuses on testing the triggering mechanisms at the federal level, the Hessian warning day focuses on the warning processes within the state itself and at the control centers.
The test alert is scheduled between 10 and 11 a.m. During this time, sirens will be activated nationwide.
Sirens that cannot yet emit the "Warning to the population" or "All clear" signal due to a pending technical conversion will be activated with the "Fire alarm" .
All clear signal also broadcast for the first time
For the first time during a test alarm in Hesse, an all-clear signal will also be sent via Cell Broadcast . Since the system does not technically provide for a classic all-clear signal, this will be issued as a hazard warning at the lowest alert level.
Depending on your smartphone's settings, this all-clear may be indicated only by a system tone or without any audible signal at all. To ensure that the message is received, the state of Hesse recommends activating Cell Broadcast even for warning level 3 .
Raising public awareness
The nationwide warning day serves to test the technical warning infrastructure and at the same time to raise public awareness of warning signals and the correct behavior in dangerous situations.
