Abstract
A CO detector includes a sensor configured to detect a presence of CO and generate a signal indicative of the presence of CO, and a controller in signal communication with the sensor. The controller is configured to measure a level of detected CO in response to receiving the signal generated by the sensor. The controller is further configured to detect a first trouble condition representative of an end-of-life condition of the sensor, and a second trouble condition different from the first trouble condition.
