Beep when manual locking unsuccessfully

When locking manually by pressing Ultralog Button. There’s no way to know if it is a successful lock or not. Sometimes door misalignment prevents successful locking.

It would be good to beep few times when locking is not successful (maybe due to bolt is jammed or there’s resistance due to door misalignment).

Workaround is to press Ultraloq one more time, if no locking sound then ok.
