HOW THE ALARM WORKS
Smart Vibration Detection
After the alarm system is activated, movement or vibration of the lock triggers a warning response.
If further movement is detected, the alarm escalates to a louder warning designed to draw attention and discourage tampering.
The alarm can reach up to approximately 130 dB, providing an additional audible deterrent alongside the physical disc lock.

Physical Locking
The disc-lock structure physically restricts wheel movement.
