For households seeking smoke and carbon monoxide detection from one device, the 30CUA10 combines hardwired power with backup operation. The three-pack is designed for homeowners, property managers, contractors, and safety professionals planning detection across a home or property.

What does the Kidde 30CUA10 detect, and how does it alert you?

Each Kidde 30CUA10 detects smoke and carbon monoxide and signals an alert with an 85-decibel sound and a bright red LED. Internal testing found 29% faster average smoke detection for Kidde 9th Edition products than leading competitor 8th Edition products in smoldering wood fire tests. Its sensing technology is also designed to help reduce false alarms from everyday cooking smoke or steam.

• One alarm combines smoke and CO detection.
• Audible and visual alert features are built into each unit.

How does the detector stay powered during an outage?

The Kidde 30CUA10 runs on 120V AC and has a built-in 10-year battery backup to help maintain detection if household power is interrupted. The backup design can help save up to $40 over the alarm’s life in battery replacements. The alarm has a 10-year limited warranty beginning on the purchase date; this warranty is for the alarm and is not a battery performance claim.

• Three detectors are included in the pack.
• The battery backup is built into each detector.

Can the Kidde 30CUA10 alert people in other rooms?

Yes. The Kidde 30CUA10 has interconnect capability with other Kidde alarms, so interconnected units can sound together when one detects danger. Interconnection options and requirements vary among models, so use the User Guide to confirm the setup for the alarms being connected. The 30CUA10 is tested to meet UL 217 10th Edition, UL 2034 5th Edition, and FCC standards.

• Interconnected alarms can provide alerts beyond the room where a hazard is detected.
• The sensing technology helps distinguish real smoke from common cooking smoke or steam.

The Kidde 30CUA10 three-pack suits homeowners and property professionals who want hardwired smoke and carbon monoxide detection with battery backup and interconnect capability. Each unit combines 120V AC operation, a built-in 10-year backup battery, and audible and visual alerts in one alarm.
