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

The X-Sense Wireless Interconnected Combination Smoke and Carbon Monoxide Detector (SC06-W, 6-Pack) offers a robust solution for home safety. Its dual protection with photoelectric smoke and electrochemical CO sensors ensures comprehensive hazard detection. The standout feature is its wireless interconnectivity, allowing all alarms to sound simultaneously if one is triggered, which can significantly enhance safety throughout a home.

It’s important to note that this device doesn’t support Wi-Fi, which limits remote monitoring capabilities. The 10-year sealed battery is a strong point, offering a long-term power solution without the need for frequent battery changes, though it will give a low battery warning towards the end of its lifespan. The inclusion of a test/silence button is a practical touch, making it easy to check functionality or silence alarms if needed.

This model supports full home coverage by linking up to 24 units, ensuring extensive protection. Since it’s battery-powered, there may be concerns about battery disposal, and the lack of Wi-Fi means users can’t receive alerts on their phones. This detector is ideal for users seeking a reliable, interconnected alarm system with long battery life, but it may not suit those looking for smart home integration 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.

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.
