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. Like the KN COSM BA, it has a voice alert to announce whether the hazard is smoke or carbon monoxide, but that and location information is not passed to other alarms in the system. It has been professionally reviewed by Consumer Reports as both a CO detector and a smoke detector, but with only middling ratings. Users are pretty pleased, however, though some complain of false alarms or of receiving the wrong/different unit compared to the model listed and pictured.
