Some smoke alarms beep when the power goes out because they are hardwired to the power system and resetting. Not all smoke alarms are hard wired to the building's electrical system.
Smoke alarms that are hard wired to the power supply will beep when the power goes out as a reminder that they are disconnected.
A good smoke alarm should have a power source from a battery so it is sure to go off in the event of a power failure. Be sure to test your smoke alarms regularly to ensure the batteries are in good working order. Hearing a high pitched "beep" throughout the house? Check your smoke alarm!

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.
