Kidde 30CUA10 Smoke & CO Detector – Hardwired with 10-Year Backup, Interconnected, 85 dB Alarm

Two-in-one protection for modern homes

The Kidde 30CUA10 combines smoke and carbon monoxide detection in a single, easy-to-install device. It uses advanced sensing technology to respond quickly to actual danger, while reducing nuisance alerts from cooking smoke or steam. The bright red LED and 85-decibel alarm provide both visual and audible cues, helping you notice warnings even from a distance or in a noisy room.

Fast, reliable detection you can depend on

In internal testing, this model delivers over 25% faster smoke detection compared with Kidde's 9th Edition technology. In smoldering wood-fire scenarios, the 29% faster performance was observed against a leading competitor’s 8th Edition devices. Real-life results vary, but the goal is clearer warnings when it matters most.
