Power Outage Issues and BPs

To start, my fiancé and I live in a centuries old row home in a very stormy region of the US. I have my BP enclosure hooked up to a wall socket for power. I already own a backup battery pack that provides 12 hours of power. I also have a mini-generator. However, sometimes I am unaware that the power goes out, because when working on the computer in broad daylight, sometimes it is hard to notice that the power is out. Also, being that our house is very old, the breaker blows sometimes and the outlets shut off. Is there such a thing as an alarm that will go off if power is cut to certain items? This is to say that the alarm would immediately go off if the power to my enclosure is cut. I am pretty good about noticing when the power is out, but there is always that chance, and I like to avoid those chances. Thanks in advance. :)

not sure how much you are willing to spend but APC has good products.

We have a UPS on some of our computer and shop controller electronics that gives about 10 minutes of power, basically just enough to shut things down cleanly. When it activates it beeps and it's quite loud.
