X-Sense SC07-MR Smart Smoke & CO Alarm vs X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts

The X-Sense SC07-MR Smart Smoke & CO Alarm is the broader safety device, covering both smoke and carbon monoxide, interconnecting with other X-Sense alarms and running five years on a battery. The X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts is CO only, but it adds spoken alerts, a temperature and humidity readout and a hub-free Wi-Fi setup for a single alarm.

No. It is a dedicated carbon monoxide alarm with an electrochemical CO sensor and no smoke sensor, so it should be paired with a separate smoke alarm. The X-Sense SC07-MR Smart Smoke & CO Alarm is the one that detects both smoke and carbon monoxide.

The X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts connects directly to 2.4GHz Wi-Fi with no base station. The X-Sense SC07-MR Smart Smoke & CO Alarm needs an X-Sense base station for Wi-Fi and the app, though its RF interconnection with other X-Sense alarms works without one.

The X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts is rated for about a year on a replaceable CR123A battery. The X-Sense SC07-MR Smart Smoke & CO Alarm is rated for five years on the same cell type, so it needs far fewer changes.

Only the X-Sense SC07-MR Smart Smoke & CO Alarm interconnects, linking to other X-Sense Link+ and Link+ Pro alarms over RF without a base station. The X-Sense XC0M-iR Smart Carbon Monoxide Alarm with Voice Alerts is standalone and is not compatible with the SBS50 base station, so it does not link or test as a group.

A household or renter that already has smoke alarms and wants a dedicated, app-connected CO monitor with spoken warnings, a climate display and no base station, in a room such as a garage or near a boiler. Buyers who want one device to cover fire and CO, or a set that alarms together, should take the X-Sense SC07-MR Smart Smoke & CO Alarm.
