Overview

Not a smoke alarm, this Kidde detector watches only for carbon monoxide, using an electrochemical sensor and a sealed long-life battery. It mounts on a wall or stands on a table, and a backlit screen shows CO readings and the peak level.

Early warnings at low concentrations give households with babies, older relatives or pets more time to react, and the sealed battery ends chirping and battery swaps. When the battery reaches end of life the whole alarm is replaced, and smoke detection needs a separate device.

Who it's for

Families with young children, seniors or pets who want notice before CO reaches dangerous levels get earlier alerts here. Homes wanting interconnected or smart alarms should look elsewhere, as no linking or app features are listed.

Pros and cons

Pros
  • Low-level warnings before dangerous levels
  • No low battery chirps
  • Peak level memory on display
  • Wall or tabletop placement
Cons
  • Detects carbon monoxide only
  • Whole unit replaced at battery end
  • No interconnect or app features listed

Performance notes

An electrochemical sensor reacts to carbon monoxide and triggers a distinct light and sound pattern at low concentrations, then a different alarm pattern at dangerous levels. Peak level memory records the highest reading since the last reset, which helps trace a brief exposure. The sealed battery powers it without swaps for its whole service life.
