If you hate your smoke detector so much, you can take the batteries out and unplug them, but you should be careful. You should know that smoke detectors are important to your home security system. Without the smoke detector, it may be hard to detect a fire at its earliest stage. So it would be best to think twice before you unplug the smoke detector.
