The start is marked by a 15-second siren sound at 12 PM. At 12:15 PM, the three-minute „Warning“ follows as a continuous tone. At 12:30 PM, the rising and falling „Alarm“ signal can be heard for about one minute. The all-clear sounds at 12:45 PM as a one-minute continuous tone.

Additionally, test messages will be sent via AT-Alert between 12 and 1 PM. At 12 PM, the Ministry of the Interior triggers the nationwide test in Austria. At 12:45 PM, the state warning centers then send a test message for the respective federal states. The message appears on mobile phones that are logged into the mobile network in the affected area. A noticeable signal tone draws attention to the message – even if the phone is set to silent.

AT-Alert complements the sirens and is intended to quickly warn people of dangers such as extreme weather, floods, or forest fires in an emergency. The test alarm serves to check the technical systems and familiarize the population with the signals. In Austria, the warning signals can be triggered via around 8,300 fire department sirens.
