So, ever since we moved in I've noticed that if you are standing in the master bathroom and someone opens or closes the back door, you can hear a bell go off in the attic. Not an electronic bell, just a bell. You can only hear it from the master bathroom. Honestly, it's pretty creepy. Maybe a renter installed it to catch their teenager sneaking out? I'm not sure what to think.
We're not able to get into the attic at the moment because the ladder is broken and not sturdy enough to climb. I'm hoping someone can shed some light on this.
