X Sense Carbon Monoxide Alarm 9
REVIEW – Over the past few years, there seems to have been a surge in carbon monoxide related illnesses and deaths. There have also been many fires where the outcome was deadly because there was no smoke detector installed. This X- Sense SC01 10 Year Battery Smoke and Carbon Monoxide Detector with Display and Alarm should take care of both issues.

What is it?

The X- Sense SC01 10 Year Battery-powered Smoke and Carbon Monoxide Detector with Display features a dual Sensor and an alarm.

The device installs easily and the display is bright. The alarm is quite loud and would wake most people up. I like the on/of/deactivate switch and the 10-year battery. The deactivate switch is an end-of-life switch once the battery dies after 10 years. At the end of the 10 years, the entire unit must be replaced as opposed to replacing the battery. I actually like this design because, with the advances in technology, I would believe that after to years there will be something better and more efficient.

Since the base has no clear marking to show the top when installing it, I attached the base to the device and then used a marker to indicate the top. I then installed the base to the wall using the mark for positioning.

I then attached the detector to the base.

What I like

  • The build quality
  • The functionality
  • The 10-year battery
  • The volume of the alarm
  • The ease of installation

What I’d change

  • My pet peeve would be a clear marking to indicate the top of the base for installation.

Final thoughts

It has a nice display that does not leave you guessing regarding any alarms or issues. It installs easily and the alarm is loud. This device is greatly needed in every home and business and is relatively inexpensive for the features that it provides. Well done!!

  2. The X-SENSE I bought in less than a year now as started showing up the Error code and I saw on the troubleshooting manual were it is said it should be replaced immediately and the unit is was manufactured 2019-09-25 which you said it would last for about 10 years.
