But your fire alarm doesn’t know that the “smoke” it senses is just your water boiling for the pasta. You’re having a relaxing evening cooking dinner and sipping on a glass of wine. (If you’re looking for a similar smoke detector that’s battery-powered, Amazon also sells the First Alert SA320CN.) Just make sure that your place is wired for smoke detectors. “Amazon Choice” item, meaning it’s eligible for Prime and is frequently sold at a steep discount.) If you’re moving into a new home or just ready to change out all of the smoke alarms in your current one, you can buy the BRK 3120B in packs of 3, 6, or 12. 1 (Speaking of Amazon, the company has made the BRK 3120B an If you don’t trust us, then trust the nearly 4,000 (!) Amazon ratings that have given this product a 4.5 star average. And when it comes to overall value, it really can’t be beat.
Sure, the First Alert BRK 3120B may not be the fanciest looking device out there, but it does sport some nice features, like a 10-year warranty and interconnectability. It also features OptiPath 360 patented technology, which means air (or smoke) can enter the device from all sides. This alarm’s dual-sensor technology will detect smoke from both smoldering and flaming fires (and maybe the occasional burnt piece of toast). Other features that you might want in your smoke alarm include digital displays, silence buttons, flashing lights (for the hearing impaired), and smart technology that connects with your phone. Carbon monoxide is known as a silent killer, and it is essential to have a sensor in your home to keep you and your family safe from the odorless gas. Lastly, for extra protection, select a smoke detector that also includes a built-in carbon monoxide detector. This type of setup can be beneficial when a fire starts in one area of your home, but you are in another location, such as the bedroom. You may even be able to connect your smoke detector to other units, allowing one smoke alarm to sound others in the house. If you select a battery-operated smoke detector, be sure to check how often the battery needs to be replaced or recharged.

A smoke detector with both types of sensing technology will offer the broadest protection for your home. While ionization sensors are excellent at detecting flaming fires, photoelectric sensors do well at detecting smoldering fires. There are two technologies generally used within consumer smoke alarms-ionization and photoelectric sensors. When shopping for a smoke detector, the best units will feature dual-sensors. Built-in carbon monoxide detectors for extra protection.The ability to connect with other sensors in your home.A hardwired setup or battery-operated unit with a long lifespan.Dual-sensor smoke alarms with ionization and photoelectric sensing.Other models only require one of the sensors to be tripped, but that also creates the potential for more false alarms. Some models require both sensors to be triggered before the alarm will go off, but this may delay the alert from sounding. Dual-sensor smoke alarms: With dual sensor alarms, you get the best of both technologies.They’re not as prone to false alarms as ionization smoke detectors, but photoelectric alarms may still be randomly set off if dust builds up inside them. Photoelectric smoke alarms: These types of smoke detectors are best at sensing smoldering fires that create a lot of smoke without many (or any) visible flames.Even the smoke produced by burnt food or by steam from the shower can trigger them, so you may get more false alarms if the alarm is placed in the kitchen or near a bathroom. The only downside to ionization smoke alarms is that they’re sensitive. Ionization smoke alarms: These are best at detecting the small particles released by fast, flaming fires.
