Safety with pre-alarm. The ABUS GRANIT™ Detecto XPlus 8077 2.0 brake disc lock sets new standards in quality, protection, and comfort. An intelligent pre-alarm alerts to movements at the lock and silences itself in case of a false alarm. If the lock is further attacked, a loud alarm of at least 100 dB will sound. Thanks to 3D Position Detection, the GRANIT™ Detecto XPlus 8077 2.0 reliably detects movements at the lock and initially triggers the intelligent pre-alarm, which stops after seven signal tones. Only after that, and with further movements, will a full alarm of 100 dB sound for 15 seconds. Additionally, the automatic brake disc recognition system knows exactly when the lock is properly secured on the disc or not. This allows the GRANIT™ Detecto XPlus 8077 2.0 to be conveniently transported in a locked position without triggering the alarm function. Multi-colored LEDs provide instant information about the activity and battery status. The hardened special steel used for the locking bolt, housing, and load-bearing parts of the locking mechanism ensures the necessary material thickness. The integrated ABUS XPlus cylinder has been specifically optimized against manipulation, for example, against picking attacks.
