# X-Sense SC07-MR smart smoke and carbon monoxide alarm

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.

## At a glance

- The alarm detects smoke and carbon monoxide, according to the product title.
- App alerts, remote testing and silence controls require an SBS50 base station connected to 2.4 GHz Wi-Fi.
- The listing describes linked Link+ Pro alarms sounding together when one is triggered, with a locate function to identify the triggered alarm.
- The listing claims a 10-year alarm life and a replaceable 5-year CR123A battery.

## Pros

- Smoke and carbon monoxide detection are combined in one alarm.
- The app is described as supporting alerts for alarms, low battery, faults and test results when set up with the required base station.

## Cons

## Specifications

## Before you buy

- 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.

## 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.

## Customer feedback

Customer feedback highlights perceived reliability, straightforward setup and use, and connectivity with other X-Sense detectors. One reported experience says linked alarms sounded even when the base unit lost electricity. These comments are relevant to buyers planning a linked system, but they do not establish performance in every installation. The overall rating distribution is strongly weighted towards five-star ratings, while a smaller share is lower, so individual experiences may differ.
- Positive themes: Customer feedback describes the alarm as reliable and easy to set up and use.
- Positive themes: Customers are reported to appreciate its connectivity with other X-Sense detectors.
