Overview
Not a plug-in or hardwired unit, this Kidde alarm runs on AA batteries and senses carbon monoxide with an electrochemical sensor. LEDs, a test-reset button and an audible alarm round out the features.
The reason to buy is a self-contained alarm that can sit in a room without wiring, with a display and a long warranty. The limit is a sparse box description and one clearly broken weight entry.
Who it's for
Homeowners and renters adding carbon monoxide protection without electrical work. The test-reset button and low battery indicator support routine checks. Those who need interconnected alarms should look at hardwired models.
Pros and cons
- Battery powered, no wiring
- Low battery indicator
- Battery inclusion not stated
- Weight entry is wrong
- Alarm volume not listed
Performance notes
An electrochemical sensor reacts to carbon monoxide in the surrounding air and triggers the audible alarm above a set level. Battery condition governs reliability, so the low battery indicator and test button matter. Placement in the room decides how quickly gas reaches the sensor.
