Advanced sensing technology further helps reduce false alarms triggered by everyday cooking.

Crystal-clear voice alerts announce "Fire!" or "Warning, Carbon Monoxide," while multi-color LED indicators provide clear visual status updates. This 120-Volt combination alarm includes a AA battery backup for uninterrupted performance during power outages.

This interconnectable alarm can be connected with up to 24 compatible Kidde devices, including up to 18 total alarms (smoke, CO, combination, or heat) and up to 6 accessories such as relay modules or remote signaling devices for comprehensive whole-home coverage. Integration with Alexa-enabled devices and Google Home (sold separately) provides voice-assisted status checks and updates, so you can monitor alarm activity across multiple platforms.

Choose the Kidde smart smoke and carbon monoxide alarm (21033277) for instant alerts and reliable protection throughout your home.
