If you’re here just to find the best smoke alarm and really can’t afford to take the time to read the excellent reviews and buying advice prepared by our researchers, this short paragraph will highlight the vital information. We have gathered a lot of information about the best smoke alarms on the market by looking at owner feedback, expert review sites, and even overall brand quality. Out of the products we have looked at, the Nest Protect S3000BWES is the best because it combines both types of smoke alarms and carbon monoxide detector, it can let you know via phone message if anything is wrong, tells you its exact whereabouts and lights your way so you can find it in the dark. The App Silence allows you to stop the alarm with your phone in case it’s a false detection, but with the Steam Check feature, that situation is very unlikely to appear. Lithium batteries ensure a long run time on a charge, and the carbon monoxide sensor has a ten years lifetime. If the Nest Protect is out of stock, you could also consider the Kidde KN-COSM-BA as we found it to be the second best option.

Buying Guide

 

Buying a smoke alarm isn’t so easy when you don’t understand the way it is supposed to work and how all the functions the manufacturer specifies are going to help you. Lately, there are a lot of models which come with interesting and exciting features that make it easy to forget about the essential properties a smoke alarm should have and the primary purpose we put them on our walls for. Here are some features you should look for when trying to find the best smoke alarm.

Kidde KN-COSM-BA Battery-Operated

Type of detection

A smoke alarm is a small apparatus that uses different types of sensors to detect elements that appear when a fire is burning. Based on the sensors they use and the kind of elements they recognize, you can find ionization smoke alarms and photoelectric smoke alarms.

Ionization smoke detectors are better at detecting fast burning fires, with open flare, but usually fail when they’re dealing with smoldered fires that burn slowly. They also have the best chance of going off for no reason. Photoelectric smoke alarms, on the other hand, are more efficient in detecting the latter category of fires, and the risk of false alarms is much smaller. In order to have both the possibilities covered, you can choose a dual-sensor smoke alarm that works with both ionization and photoelectric technology.

As a considerable addition, you can now find smoke alarms that include CO detectors, absolving you from the installation harass of separate devices and making your home even safer.

 

Power source

Naturally, alarms may be wired to your electrical system or they can run on batteries. The big downside of electrical wiring is that the installation process has to be operated perfectly, and this is why the help of an expert is usually recommended. Also, in the case of power outages, the appliance won’t be functional, and fluctuations of the electric flux might trigger a false alarm. If you want to connect the smoke alarm to your electrical system, it is best if you find a model that has an emergency battery it will switch to when the power is down.

Battery powered smoke alarms also have some disadvantages. The batteries will need to be replaced, and most of these detectors will make a chirping sound when the batteries are low, which you may find stressful if it happens in the middle of the night. If you plan on buying this type of alarm, you should consider one that uses lithium batteries, as they have a longer run-time life.

 

Type of signal

Outside from the classic beeping sound, there are other types of signals that are meant to be efficient for people who might not be sensible to acoustic alarms. Many of the new smoke alarms use voice alerts which have been proven to be more effective for children. Some of them even offer the possibility to record your own voice to make it more noticeable.

Other smoke detectors use strobe lights that are especially recommended for hearing impaired people.

Interconnectivity

However high is the alarm sound, it is possible that now and then you won’t be able to hear it unless you’re in the same room. This is why an interconnected smoke alarm system is suggested as the safest option. Such a system will make every alarm connected to it sound as soon as one of them is triggered. However, this feature is more expensive, and the installation is quite difficult. It will consume more power, and so it is usually encountered in hard-wired systems. But you can also find wireless, interconnected alarms which don’t need you to connect them in any other way than the electrical system if it’s the case.
