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.
