Answer
A smoke detector or smoke alarm is a device that detects smoke and issues an alarm to alert nearby people that there is a potential fire. Technically, they could also be described as an active fire protection device that is subject to stringent bounding. A household smoke detector will typically be mounted in a disk shaped plastic enclosure about 150mm in diameter and 25mm thick, but the shape can vary by manufacturer.
Because smoke rises, most detectors are mounted on the ceiling or on a wall near the ceiling. To avoid the nusance of false alarms, most smoke detectors are mounted away from kitchens. To increase the chances of waking sleeping occupants, most homes have at least one smoke detector near any bedrooms; ideally in a hallway as well as in the bedroom itself.
Smoke detectors are usually powered by one or more batteries but some can be connected directly to household wiring. Often the smoke detectors that are directly connected to household wiring also have a battery as a power supply backup in case the household wiring goes out. It is usually necessary to replace the batteries once a year to ensure appropriate protection.
Most smoke detectors work either by optical detection or by ionization, but some of them use both detection methods to increase sensitivity to smoke. Smoke detectors may operate alone, be interconnected to cause all detectors in an area to sound an alarm if one is triggered, or be integrated into a fire alarm or security system. Smoke detectors with flashing lights are available for the deaf or hearing impaired. A smoke detector cannot detect carbon monoxide to prevent carbon monoxide poisoning unless it has an integrated carbon monoxide detector.

Answer
If it's unplugged the device will still work and a cautionary beep is emitted to let you know your battery is dying.
Take the 9 volt out of the back and replace it. If that doesn't work maybe the censor in the actual device is defective.
As a cautionary step I would take it outside and attach an extension cord to it. If it's detecting extreme levels of carbon monoxide outside, you'll know it's faulty and should just replace the entire unit.
