Thanks! Several different encouraging answers there.
I've already got APC UPSs scattered around the house for various pieces of hardware. But those only stay good for a few hours when the AC fails, I assume because they self-cannibalize the battery power bringing up some hardware that makes 110v available (they hum -- then a few hours later they start to whine, whistle, or beep, and then they die). And those UPSs use 12v lead-acid batteries that don't like complete discharge. I'd rather use lithium-ion cell or NiMH battery packs that are a bit more likely to survive.
So -- Dane, can you ask your techs to look into how to provide that small amount of battery power for the system?
What voltage is it going to require? and how should everything be connected? Pictures would help.
I can get a solar panel and one of the "power bank" devices that are becoming increasingly common and set up whatever is required. There are some power banks that automagically reset themselves after a cloud crosses the sun and the solar voltage drops, but others simply go to sleep til reset. So it will take some investigation to find the right hardware.
They're saying plan for no AC power for maybe 3 weeks. Not to mention water and fire protection, which will also take a while to reorganize. In the meantime, telecom is going to be vital.
(We have community neighborhood emergency plans that include GMRS radio coordination, with us licensed ham radio operators serving to relay messages to the local city offices, for example, on the assumption the phones will all fail.)
And I'd like to do the preparation with the available lead time between now and April, and make up the backup battery equipment for some of the elderly neighbors who are asking me about life safety stuff, so when Sonic comes to put in their and our fiber, the Sonic tech will recognize and know how to connect the backup battery power.
Sorry to be anticipating trouble. But we're only a few blocks from the Hayward Fault here and expect to get all shook up. And Sonic is, I hope, to be a lifeline once things fall apart and the center does not hold ...
