Yes. Multiple Kidde alarms with smart features can be installed in a residence and can be assigned to appropriate rooms (Kitchen, Living Room, etc.).

Both Smoke + Carbon Monoxide Alarms with smart features and Smoke + Carbon Monoxide Alarms with Indoor Air Quality Monitors are capable of communicating with other Kidde AC Model Alarms through Hardwire Interconnect. However, only limited information is transmitted from the non-Wi-Fi alarms. This information is limited to smoke or CO alarm events only.
