Upgrade your home with the Kidde Smart Smoke and Carbon Monoxide Alarm, featuring WiFi enabled Ring App connectivity. With the Ring App (no paid subscription required), you will receive real-time notifications for smoke, CO, and low-battery alerts. An optional Ring subscription adds professional monitoring and emergency assistance. Smart home integration expands with Ring cameras (sold separately) for added visibility if an alarm is triggered.
This hardwired alarm features both photoelectric smoke and electrochemical CO sensors, providing faster and more accurate detection of both smoldering fires and carbon monoxide. Its advanced sensing technology reduces false alarms from cooking, and the HUSH feature silences nuisance alerts for 8–10 minutes.
To make alerts easy to recognize, the alarm uses crystal-clear voice prompts ‘Fire!’ and ‘Warning, Carbon Monoxide’ along with multi-color LED indicators for quick visual confirmation. This 120-Volt combination alarm includes AA battery backup to maintain coverage during power outages.
Interconnect up to 24 compatible Kidde devices, including a maximum of 18 alarms and 6 auxiliary modules, for whole-home protection.
Monitor your home and receive alerts when you're away with Kidde's Ring App integrated Smoke and Carbon Monoxide Alarm (21033275).
