Ring is still sounding the alarm

hi, i recently had activity in my home where motion was detected in a bedroom, ring sounded off the alarm and after 10 mins. the siren was silenced (by the system?). i then received further messages stating that “ring is still sounding the alarm” 5 mins after the siren was silenced. What does “ring is still sounding the alarm” mean after the siren was silenced? As I did not silence the siren, is this automatic after 10 mins? Thank you for your attention, Gsrodr
