[RE-wrenches] Off Grid Alarm

[Ray Walters]

We looked into this recently as well, and didn't find any good options 
that didn't involve us making a custom gizmo of some type.  The closest 
off the shelf product I found was just an AC smoke alarm that chirps 
when it loses AC.   I think some of the little UPS boxes also have an 
alarm when they lose AC input.
