In some countries, the law prohibited the trigerring of a Siren for more than 3 minutes. That is why our systems stop to ring after 3 minutes.
Notice that you can choose if the siren should ring immediatly or after a pre-alarm period. You will find more information on the link below:

In case of confirmed alert:
You do not have to stop the siren yourself. Also, by letting the siren stop on its own, you keep your system armed.
In case of wrong alert:
You can of course immediately stop the siren by pressing the "OFF" button on the badge or app.
