I have a battery powered alarm system that uses very little power. It has an internal, and external horns that sound at 165 decibels. Probably can be heard a mile away. Anybody inside would get out quick.
I think the company is called sun, wind, and ???. The company is in Jamestown Ny. The box is at my cabin. I remember it was hard to find something like that on the internet. I think I googled cabin alarms.
