The X-Sense SC07-MR is a battery-powered smoke and carbon monoxide alarm with app features that require a separate SBS50 base station. It may suit an existing compatible X-Sense setup, but the alarm’s app connection and linked-alert functions depend on that hub.

Listing details to confirm

The listed battery life is 5 years, while the feature description claims a 10-year alarm life with one battery replacement. Treat these as separate listing claims and confirm the replacement schedule and total service life before buying. The product style also says a base station is required, and the listing does not clarify whether one is included in this 1-pack.

Who is it for?

A good fit for

People who need a combined smoke and carbon monoxide alarm and already use, or plan to obtain, an SBS50 base station.
Households wanting app notifications and remote test or silence controls, subject to the required hub and Wi-Fi setup.
Buyers considering linked alarms who want the listing’s stated group-alert and locate functions.

Less suited to

Buyers who need app features without a separate SBS50 base station.
Buyers seeking a clearly stated single battery-life figure, since the listing separately claims a 5-year battery life and a 10-year alarm life.
