Designed to fit the majority of motorbikes fitted with disc brakes, this sturdy alarm is a convenient way to ensure you have protection for your vehicle wherever you go. Simply push the lock in to the body of the unit to set the alarm, which will be notified by a short beep. 15 seconds later, the alarm will become activated. If the body of the alarm is vibrated by somebody tampering with it or your motorcycle, the alarm enters warning mode, and if further vibrations are received within 5 seconds, the alarm will ring until the vibrations stop. After 35 seconds with no further vibrations, the alarm will cease and will automatically re-arm itself. Of course, the alarm will also cease if the lock is disengaged by using the keys - 2 keys are supplied with each alarm unit together with batteries. The battery holding part of the alarm is designed so that it cannot be accessed whilst the alarm is fitted.
