Well, it has been working fine, when I've pressed the Test Button..
But this morning at 6:45AM, it woke us up out of a deep sleep.
My wife said, "What's wrong!", and I said "The grid is down!" and jumped
up to go reset that long loud beeeeeeep!
As I switched off it's little 9V battery, I said to myself,
"It's too early to be the Rapture, go back to bed now"..
The power failure only lasted about a minute, and came back on..
There were three or four happy beeps from the kitchen (Stove or gas-CO alarm)?
The Sanyo shudder stayed closed w/o power LED on..
About two minutes later, it came back on in heat mode.
I guess the 5-minute transmittance cycle was up.
(The Sanyo remote shoots an IR data burst every 5 minutes)..
In an actual emergency (long grid failure while raining), I would have
turned on the battery-backup system and gone back to bed.
But as you can see, I couldn't sleep.. That's my story and I'm sticking to it..
Happy End Times,
Rich
