What Patrick said.

But, on a minor note that probably won't affect your Symmetra but I'm 
posting in case anyone else here can shed light on.... we had a power 
event this AM. The transfer switch did it's magic and all was good... 
Except for two new APC1400's- they failed once the batteries drained. I 
triple-checked that they were on the right panel, played with 
sensitivity, even tried daisy-chaining one off a good working 2200. 
Nothing I did would convince the two 1400s they had power. Once the 
house power was restored they came back to life and look normal. I later 
learned that two of our colo customers with APC1400s had the same 
problem :( Other models (even a couple non-essential lower-end, dumb APC 
450s and 650s) didn't blink at the generator power.
