Kidde 4-Pack Hardwired Smoke & CO Detector with 10-Year Back-Up, Voice Alerts & Interconnect — 30CUA10-V

Enhance home safety with the Kidde 30CUA10-V 4-pack, designed for ceilings across living rooms, hallways, kitchens, and bedrooms. These hardwired detectors combine reliable smoke and carbon monoxide detection in a sleek 5-inch form factor, bringing modern safety features into everyday spaces.

2-in-1 Detection and Clear Alerts

These units monitor both smoke and carbon monoxide with a single device, simplifying placement and maintenance. An electrochemical sensor supports CO detection, while the detector delivers fast, distinct voice alerts that clearly identify the detected hazard, helping you respond swiftly.

Resilient Design and Compliance

Powered by 120V AC with a built-in 10-year lithium battery, the alarms offer long-term reliability with minimal upkeep. They are comprehensively tested to meet current safety standards and UL requirements (UL 217 9th Edition, UL 2034 4th Edition) and FCC compliance, providing peace of mind for everyday living.

Interconnected Protection

Interconnect capability means when one alarm sounds, all connected units chirp in unison. This coordinated alert pattern can help create a faster, more organized evacuation in multi-room layouts.

What’s in the Box

The package includes four detectors and a twist-and-click mounting bracket for straightforward installation. The compact 5-inch design is suitable for multiple living spaces, and the LED warning indicators offer quick at-a-glance status checks from across rooms.
