Disc Brake Alarm Lock
1) This alarm padlock is widely used to fit on to the brake disc of a motorbike to prevent theft. 2) To alarm the padlock, place it over the front motorcycle brake disc and push key port in. Ensure that the locking pin fits into a slot or hole in the disc. At this point the lock will beep and the alarm will set after 15 seconds. When the lock is vibrated, within 5 seconds the alarm will sound ( 5 second delay allows the lock to be opened by key without alarming). 3) The two tone 110db siren will sound for 10 seconds when triggered and will sound again if triggered again. After 35 seconds without a trigger, the padlock will re-set so that a further trigger will give the triple beep warning before alarming.
