A padlock with an alarm that sounds an alert when it senses a vibration.
Because it is a padlock (padlock) type, it can be used not only as a disc lock but also in combination with your existing chain. The alarm function can be selected ON / OFF by inserting a U-shaped shackle.

Alarm built in: alarm goes off when motions and vibrations are detected
Water-repeat (not water-proof)
Two keys included
