Why do smoke detectors make a beeping noise when the electric goes off they are not hooked to any electric?

When the electricity goes out, a smoke detector may make a final beep as it's capacitor is discharged, as a warning. If the smoke detector has a battery backup, some detectors will beep just to let you know the power is off, and some other units will only beep when the power is off AND the battery is low. Usually there is a legend on the back of the unit that will tell you what the different beeps mean.
