Top 10 Best Smoke Detectors
Smoke detectors are one of the most important devices we have in our homes, yet they are also one of the most overlooked as well. The bottom line is that they save lives and people should give more thought to make sure they have good quality alarms and also ensure that they are working.
So what should a buyer look for? There are two main types of sensors that detectors employ – photoelectric and ionization. Most models have just an ionization sensor that works for detecting flaming fires. Photoelectric sensors detect smoldering smoke. So the best smoke alarms will have both sensors, but you can also use a combination of both types placed in strategic spots throughout your house.
Buyers should also be aware that they can be powered either by batteries or hard-wired into your electrical system. Those that are hard-wired can be more difficult to install, but are more likely to work in the event of an emergency. Interconnected alarms are another feature to look for. These models can communicate with each other so that when one alarm goes off, they all go off. These are typically hard-wired, but there are now wireless options available.
Below we review our choices for the top 10 best smoke detectors. At the bottom of these smoke alarm reviews we also have a comparison chart to easily compare one smoke detector versus another.
