TWENTY YEARS OLD?? I hope you're not depending on it to save your life. Mine are 5 years old and I'm considering replacing them. Mine are wired together so that if one sounds they all sound. So ANY fault and I'm getting a warning of it. And 20 years ago I don't know if they had CO detectors. If not then you definitely want to upgrade to one that detects Carbon monOxide. Hope this helps.
