The Abus Bordo 6000 Alarm brings all the functionality and security of the shop favourite Bordo 6000, but with an integrated alarm system. When tampered with, the Bordo 6000 emits an alarm at 1000db for 20 seconds to deter thieves. Once it turns off (automatically,) it resets the alarm. While no lock is invincible, the Bordo 6000 Alarm adds another layer to an already extremely secure lock. Consider this lock for high-end bicycles that are locked up in a communal or off-site space like a garage or bike room.
