The alarm system is already set up. It involves and Idec ice cube relay
with a 240 V coil connected between L-1 AND L-2 of the AC in bus bars.
When the grid drops out, the relay reverts to the N/C position, allowing a
120 V contact to send power to a box in the dining room (that has the

Sounds like a perfect use for an Arduino driven speaker.
There are thousands of publicly posted circuits that will probably net a simple

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 th

Hi Carl,
We too provided power to a home owner for an alarm system (and more) for a
remote vacation cabin in the heart of meth. country several years ago. The
cabin had previous wiring provisions for lighting, etc. on one 15A AC
circuit, when occupied, so this is not a carbon copy of your require
Carl,
We designed and built a custom solar power system for an alarm company about
4 years ago. They were installing the system on an un-occupied warehouse
that had no electricity. The two things we had to address was make sure we
had correct voltage/current battery charging arrangement as we di
Carl,
Alarm systems typically already have batteries. Usually 9 or 12 Ah VRLA.
For an off-grid version, I would size the battery based on the once a year
event where the alarm is going off non stop for two days. That should also give
some cloudy weather storage.
If possible, get all their eq
