Uh -- if you have a UPS, why are you using a surge protector as well? The function of a UPS is to condition your power supply. It puts out clean 110/220V 50/60Hz power (depending on where you live) irrespective of what it is getting from the mains. That is, the UPS also does all the surge protection function itself. Not only that, it should cope with surges by absorbing them, rather than blowing a circuit breaker, so it carries on running after the surge is over. Admittedly some UPS designs are better than others -- inline UPSes are the best, but tend to be more expensive. These work by converting the input to DC and then converting back to AC. Cheaper UPSes monitor the characteristics of the incoming current and switch to battery power if it is out of specification, which is not really failsafe. Also, didn't your UPS sound the alarm? They are normally too loud to ignore easily.
