Something went off in the middle of the night at an odd time - like 0140. Of couse it was a single shreik and I didn't really know what it was. Went into the kitchen and since it didn't go off again, just went back to bed. The next night it happened again, maybe at the same time, I don't know but I was ready to take a hammer to anything that might have any kind of buzzer in it because I still didn't know if it was a computer, a clock, or the fucking fire alarm. I got rational the next day and replaced it's battery, turned off both computers and put my clock in the truck and we made it through the next night OK. The clowns that design this stuff need to put some sort of visual indication (like and let) and the piece of shit because at that time in the morning I'm ready to pile computers, clocks, phone, and alarms all up on the floor and take a hammer to the pile to make sure it doesn't happen any more. I bet next time, I just throw away the battery.
