10 Best Smart Smoke Detectors 2026 in the United States

The FIRST ALERT BRK PRC710V is a dual-function smoke and carbon monoxide alarm that utilizes both electrochemical CO sensing technology and photoelectric smoke sensors. This combination ensures accurate detection of both smoke and carbon monoxide, minimizing false alarms and providing peace of mind. One of its standout features is the built-in 10-year battery, which eliminates the need for frequent battery replacements and complies with various U.S. state regulations.

Additionally, it includes a voice alert system that clearly states whether the danger is smoke or carbon monoxide and indicates the specific location from a preprogrammed list of up to 11 locations in your home, making it easier to respond to threats quickly and efficiently. Installation is straightforward, thanks to its easy-to-mount design and included mounting bracket. The low-profile design helps it blend seamlessly with home decor.

However, this alarm does not offer smart home integration, which might be a drawback for those who are looking to connect their safety devices to a broader home automation system. The alarm relies solely on audible alerts and voice notifications, which are loud and clear but may not be sufficient for individuals who are hearing impaired. This device is best suited for those looking for a reliable, low-maintenance smoke and carbon monoxide detector without the need for smart home features.

The Kidde Smoke Detector & Carbon Monoxide Detector Combo is a dual-function device designed to enhance home safety by detecting both smoke and carbon monoxide. It features a photoelectric sensor for identifying slow, smoldering fires and an electrochemical sensor for detecting carbon monoxide, providing comprehensive protection. The 85-decibel alarm and red LED alert users to any hazards, ensuring they are promptly informed.

One of the key advantages is its 10-year lithium battery, which eliminates the need for battery replacements and maintains functionality even during power outages. The Test-Hush button is convenient for regular testing and silencing false alarms, such as those caused by cooking or steam from showers. Installation is straightforward as the alarm automatically activates when mounted, with no need for pull tabs or switches. Additionally, the device will chirp at the end of its life cycle, indicating it needs to be replaced.

However, this smoke detector lacks smart home integration, which may be a drawback for users looking to connect it to a broader home automation system. Its reliance on battery power only, without a backup hardwiring option, might also be a concern for some. Its ease of use, dual detection capability, and long battery life make it a solid choice for those looking for a reliable and efficient smoke and carbon monoxide detector.

The First Alert BRK SC-9120B is a reliable smoke and carbon monoxide detector that uses ionization technology to detect smoke, paired with a superior CO sensor. It is designed to hardwire into your home’s electrical system and includes a 9-volt battery backup to keep it running during power outages, which is a strong safety feature. The alarm is audible and has separate indicators for smoke and CO, helping you understand what kind of danger is detected.

Installation is simplified with an easy-to-use universal mounting bracket, and it interconnects with other First Alert and BRK hardwired alarms, meaning if one alarm sounds, they all do, which is great for larger homes. However, it does not offer wireless connectivity or smart home integration features, so you won’t get smartphone alerts or control through apps like some more modern detectors provide. Its 10-year limited warranty suggests long-term durability.

This model is best suited for those wanting a dependable, no-frills alarm system hardwired into their home’s power, with backup battery support, but it may not appeal to users looking for smart features such as Wi-Fi connectivity or app notifications. The device’s clear audible alerts and separate indicators add to ease of use, making it a solid choice for homeowners focused on basic, effective smoke and CO detection rather than smart home integration.
