Oxford BOSS Alarmed padlock can be used with the alarm activated or without. Handy when the lock is in use on a moving vehicle. OF3 has a 14mm (0.54") hardened steel shackle double secured into a plastic encased steel lock body which houses the alarm unit electronics and a replaceable battery pack. 3 high security abloy type keys are supplied as well as bright yellow reminder cord for use a motorcycle disc lock. BOSS OF3 is a great match with our 14mm Maximum Security Chains.
To activate the alarm, simply insert the shackle with the red band matching the red arrow on the lock (reverse secures the shackle without arming). When tampered with, the alarm will go off for about 10 seconds and re-arm itself.
