Upgrade your home with the Kidde Smart Smoke and Carbon Monoxide Alarm, featuring WiFi enabled Ring App connectivity.

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.
