Kidde 2-in-1 Smoke & CO Detector (30CUDR) – AA Battery Powered, 85 dB Alarm

Protect your home with the Kidde 30CUDR, a dual-sensing alarm that covers both smoke and carbon monoxide. Operated by AA batteries, it offers a wire-free setup that makes installation quick and simple for any room.

Two-in-one detection combines fast smoke sensing with CO monitoring, providing an earlier warning in many scenarios. In internal testing, smoke detection was more than 25% faster on average compared to some leading units, helping you react sooner. The device emits a loud 85-decibel alarm and uses a red LED light to provide a clear visual cue even in noisy environments.

Designed to reduce nuisance alarms, advanced sensing technology helps distinguish real flames or smoke from everyday cooking or steam. This keeps you focused on true threats while maintaining reliable performance when smoke or CO is present.

Setup is straightforward: simply install the unit, powered by two AA batteries (included). A convenient low-battery chirp notifies you when the power source needs replacement, and the 10-year limited warranty offers long-term confidence from the date of purchase.
