Zipato Siren: Use Doorbell Sound?

By the way, one of the easiest and safest ways to do this, if you’re allowed to drill through the wall, is to just use a conventional doorbell button on the outside, and have pressing it close a circuit which can be detected by a contact sensor that you have mounted inside the house.
