ALARM LOCK INSTRUCTION:

When you secure the lock to a disc, it will beep once. You then have 15 seconds to press
 the button and thereby activate the alarm. When you do, you will hear a second beep.
Once the siren has been set off, it will continue to sound for approximately 10 seconds and then
 it will silence itself and then re-set and re-arm in read lines for any further attacks.
If the lock position is changed the lock will emit 4 warning beeps.

If left alone it will reset itself.
If within a few moments it is moved again or attacked, 

the siren will emit a loud sound as a warning of an attack.
