Wow, thank you so much for such a great and detailed feedback. The lack of visual response when hovering is a new issue, I will try to improve it. Also, you may have misunderstood the purpose of the siren off button, which mutes the siren's current sound and does not affect its further activation.

Actually, separate sirens are used to indicate the onset of day and night (night - 3 short signals, day - 1 long one), so as soon as you hear and recognize a siren, you can safely turn it off and wait for the next one. But I realized that I also need to describe this in more detail at the beginning, especially because, as in life, the alarm signal (dark saturation) can be longer than the dark saturation time itself, so you probably did not recognize the second siren (daytime).
