Carbon monoxide alarms have a limited life, typically 5 to 7 years (some even less). Most people donât realize they need to replace a $25 - $75 item after several years.
The alarm points on carbon monoxide detectors are not a simple alarm level (as in smoke detectors) but are a concentration-time function. At lower concentrations (e.g. 100 parts per million) the detector will not sound an alarm for many tens of minutes.
