Most hard-wired smoke detectors include a 9-volt backup battery that's supposed to kick in if your home loses electricity. If that battery is running low, your detector alerts you with a high-pitched beep. Remove the old battery and replace it with a new one. Press the “test” button and listen for a beep.
