10 Best Smart Smoke Alarm 2025 in the United States

The X-Sense Wireless Interconnected Combination Smoke and Carbon Monoxide Detector is a solid option for those looking to enhance their home safety. One of its standout features is the wireless interconnectivity, allowing all alarms in the system to sound an alarm if any unit detects smoke or carbon monoxide. This helps ensure that alerts can be heard throughout your home, which is crucial for safety.

The product boasts both photoelectric and electrochemical sensors, which provide reliable detection of both smoke and dangerous CO levels. Its informative LCD display is a significant advantage, giving real-time CO level readings and battery status, adding to user convenience.

With a built-in 10-year battery, there's no need for constant battery replacements, which saves time and reduces hassle. The 6-pack option is a great value for those looking to protect multiple rooms in a house, covering an area of 215-430 sq. ft. per unit. However, the unit lacks Wi-Fi capability, which means it won't connect to smart home systems or send alerts to your phone. If Wi-Fi connectivity is a priority for you, you would need to look at their SC07-WX model. Additionally, while the installation is straightforward with a screw-in method, some users may still find it challenging if they are not handy.

The X-Sense Smart Smoke and Carbon Monoxide Detector Combo is a solid choice for those looking for a reliable and interconnected home safety solution. One of its biggest strengths is its comprehensive coverage, as it includes five detectors linked to a single base station, ensuring that any alert will notify all devices simultaneously. This can be particularly beneficial for larger homes where alarms may be placed in different rooms. The app features allow for easy monitoring, letting users receive instant alerts and control the alarms from their smartphones without needing to climb ladders to test or silence them.

The ability to name each detector based on its location is a thoughtful touch that helps users quickly identify the source of an alert. The 10-year lifespan with just a single battery replacement is also a convenient feature.

The system relies on a battery-operated power source, which may not be as reliable as hardwired options, especially if batteries are not replaced on time. Additionally, the quick dispatch service for emergencies requires a subscription to the Protect+ plan, which may not appeal to everyone. While this combo does provide vital smoke and carbon monoxide detection, potential buyers should consider whether they want to invest in the additional monitoring service.

The X-Sense SC07-MR51 combo is well-suited for families who value smart technology and interconnected safety features, but those preferring a hardwired solution or who are hesitant about monthly subscriptions may want to explore other options.

The X-Sense Smoke and Carbon Monoxide Detector Combo is a strong contender if you're looking for an all-in-one safety solution for your home. One of its standout features is the wireless interconnection capability. This means if one alarm detects smoke or carbon monoxide, all connected alarms will go off, ensuring that you and your family are alerted no matter where you are in the house. This setup supports up to 24 interconnected devices, which is excellent for full-home protection.

The product also boasts a 10-year sealed lithium battery, so there's no need to worry about changing batteries frequently, and it ensures the device is always operational. It combines smoke and carbon monoxide detection, offering dual protection in a single unit, which is highly convenient and space-saving. Made from heat-resistant and high-temperature resistant PC material, it is durable and reliable.

However, it's important to note that while it supports wireless interconnection, it does not have Wi-Fi capabilities. This means you won't receive alerts on your smartphone if an alarm is triggered, which is a downside for those looking for smart home integration. Installation is straightforward, thanks to the wireless design, but keep in mind that the unit is powered by 12 included lithium metal batteries, so you should ensure they're all properly installed and maintained. For those looking for a reliable, interconnected smoke and carbon monoxide detector without the need for smart home compatibility, the X-Sense Combo provides robust protection with minimal upkeep.
