The AP08 is a new concept that gives the user double the security of a conventional padlock. Once armed, if the padlock is moved or knocked the loud two tone alarm will sound. This 110d B siren continues for 10 seconds & is a great deterrant to the would be thief or opportunist burglar. Our new design makes it very difficult for the sound to be muffled & the siren is loud enough to put off all but the most determined. After ten seconds the padlock re-arms ready to deter the next person foolish enough to tamper with it.
