10 Best Smoke Detector Carbon Monoxide Detectors Combo 2025 in the United States

The X-Sense Wireless Interconnected Combination Smoke and Carbon Monoxide Detector offers a comprehensive safety solution for your home. Equipped with both a photoelectric smoke sensor and an electrochemical CO sensor, it ensures reliable detection of both smoke and carbon monoxide. This 6-pack model allows you to interconnect up to 24 devices, ensuring that when one alarm goes off, all of them do, providing extensive coverage and early warnings throughout your home.

One standout feature is the built-in 10-year lithium battery, which means you don't have to worry about replacing batteries for a decade. Additionally, the LCD display is very informative, showing real-time CO levels, battery status, and working status, which helps in maintaining the device easily. However, it's important to note that while these detectors support wireless interconnection, they do not have Wi-Fi capabilities. If you need Wi-Fi, you would want to look for a different model, specifically the SC07-WX. The alarms are battery-powered, which makes installation straightforward without the need for hardwiring.

The detectors are made from heat-resistant PC plastic, making them durable and reliable. If you're looking for a combination smoke and CO detector that ensures extensive coverage, long battery life, and ease of use, the X-Sense SC07-W is a solid choice.

The X-Sense Smart Smoke and Carbon Monoxide Detector Combo is a solid choice for those looking to enhance their home safety without the hassle of hardwiring. One of the standout features is its battery-operated setup, which allows for easy installation without needing an electrician. It comes with a base station that ensures all linked alarms sound together, providing a comprehensive alert system that can be especially beneficial in larger homes.

The app integration is another significant advantage. Users can receive instant notifications on their smartphones, making it easier to stay informed about potential dangers even when away from home. The ability to test or silence alarms through the app adds a layer of convenience, eliminating the need to climb ladders. Furthermore, the option for 24/7 professional monitoring can provide peace of mind, ensuring quick response times in emergencies.

However, there are a few drawbacks to consider. Being battery-operated means that users must remember to replace batteries every few years, although the 10-year lifespan of the alarm itself is a positive aspect. Some may find the need for a premium subscription for professional monitoring unnecessary, especially if they already feel comfortable managing the alarms themselves. Additionally, while the technology is user-friendly, those who are not tech-savvy might take some time to fully utilize all the app features.

The X-Sense Smart Smoke Detector Carbon Monoxide Detector Combo (model SC07-WX) offers a dual sensor setup combining photoelectric smoke detection and electrochemical CO detection, which ensures accurate and reliable monitoring. Powered by replaceable CR123A lithium metal batteries, this unit is convenient as it doesn't require hardwiring, making it easy to install and maintain.

With Wi-Fi connectivity, it can send real-time alerts to your smartphone via the X-Sense Home Security app, keeping you informed about alarms, low battery notifications, and faults from anywhere. However, these devices operate independently and do not support interconnectivity, which means they won't communicate with each other or a central base station. This could be a limitation for those looking for a fully integrated home safety system.

The ten-year sensor lifespan is commendable, providing long-term assurance. Additionally, there’s an option for a Protect+ Premium subscription for 24/7 professional monitoring, which can dispatch emergency services quickly. The device-sharing feature allows you to share access with up to 12 people, adding a layer of security. The audible alarm ensures you're alerted even without your phone. However, the reliance on a 2.4 GHz Wi-Fi connection might be a drawback for users with dual-band routers that prefer 5 GHz. Potential buyers should consider its independent operation and Wi-Fi requirements before making a purchase.
