The Siren Padlock Alarm is a metal padlock which looks like any other metal padlock you’ve ever come across, which is why it might be effective against someone otherwise able to disable an electronic alarm.

Once unlawfully disturbed it will blast the perp and your neighborhood with a 10 second and 110 decibel sound assault. That’s on par with a chainsaw, and a little below a vuvuzela, which punches in at 130 db.

If it was twice as loud, you could use it as a sound grenade, but unfortunately such fantasies must be left aside for now.
