It receives top ratings across the board for detecting high concentrations of CO, low concentrations of CO and the quality of its alerts. The Kidde KN COSM BA Est. $35 is also worth considering. This combination smoke and CO alarm has been around for a number of years, and was previously known as the Kidde KN COSM B. It has two key differences compared to the SCO501CN 3ST: It is a stand alone detector that does not communicate with other alarms and the smoke detector uses ionization, not photoelectric technology. It has a voice annunciator that will identify the type of hazard fire or CO, but can't relay that to other detectors. It's not been professionally reviewed, but there's a large body of mostly satisfied users that post feedback at Amazon, where its overall score is 4. 4 stars following around 1,750 reviews. The Kidde KN COSM IBA Est. $40, previously known and sometimes still available as the Kidde KN COSM IB, is the hardwired version of the Kidde KN COSM BA but one with a significant difference: It can interconnect with up to 24 Kidde alarms plus an additional six sounding devices. However, it relies on a hardwired connection to do so, so unless you have an existing network of Kidde alarms, it's best for new construction or a major renovation project.
