A capable two in one alarm with a sealed 10 year battery that most reviewers found easy to install and reliable, though a couple of buyers hit a dead unit out of the box, so it is worth testing right after installing.

Overview
The X-Sense SC06 is a combination smoke and carbon monoxide alarm in one unit, powered by a sealed 10 year lithium battery rather than a replaceable AA or 9 volt. It is UL 217 and UL 2034 certified and installs without wiring.
Where the Kidde alarms above watch only for smoke, the SC06 also covers carbon monoxide, so one unit does the job of two separate detectors. The sealed battery means nothing to swap for a decade, though it also means the whole unit gets replaced rather than just a battery once it reaches end of life.
- Sealed 10 year lithium battery, no battery swaps
- Combined smoke and carbon monoxide detection
- 85 dB alarm with photoelectric and electrochemical sensors
- One button test and silence operation
Who it's for
Fits homeowners who want smoke and CO coverage from a single detector without running separate units, especially in bedrooms and near fuel burning appliances. Anyone who prefers a user replaceable battery, or wants smoke detection only, should look elsewhere.
What buyers say
From Amazon customer reviews.
Reviewers who cook a lot liked that it stopped tripping on kitchen smoke and steam, and several called the sealed 10 year battery a real advantage over units that need a fresh 9 volt every year. One buyer went about four months with no false alarms after installing it, and others were replacing 10 year old alarms with it and said they trust the brand. The clear complaint is a dead on arrival issue: one buyer got two units in a row where the status light never came on and the test button did nothing, and because the battery is sealed in, there was no battery swap to try as a fix. Another noted the box arrived beat up, though the alarm inside still worked.
Strengths and trade-offs
Drawn from this product's published specifications.
- Covers smoke and CO in one sealed unit
- 10 year sealed battery, nothing to replace
- One button test and silence
- UL 217 and UL 2034 certified
- Sealed battery means the whole unit is replaced at end of life
- A small number of buyers received units that would not power on
Performance notes
Photoelectric and electrochemical sensors handle smoke and carbon monoxide separately inside the same housing, and X-Sense says the upgraded sensors improve response speed while cutting down on false alarms. A single button tests and silences the unit, and a low battery warning signals as the sealed cell nears the end of its 10 year life.
