Best Smoke Detector 2017

Keeping your home safe for your family is always your first priority. Household safety means keeping poisonous chemicals out of the reach of young children, making sure that small appliances like curling irons and coffee makers are shut off and unplugged, and ensuring that everything in your home is sound and secure.

One of the most important things you can do for your home is make sure you’re prepared in the event of a fire. This means keeping a fire extinguisher in your kitchen, turning off the stove when not in use, and of course, making sure you have working smoke detectors installed throughout your home.

What Is A Smoke Detector?

A smoke detector is a device that is installed on your wall or ceiling that detects the presence of smoke in your home or office. Once smoke is detected, a sound will emit from the device, which allows anyone sleeping or occupied in other areas of the home to get out safely. All homes should have multiple smoke detectors to protect them in the event of an unexpected fire. If you don’t have one in your home, you are in trouble!

Smoke detectors are housed in plastic enclosures, typically shaped like a disk about 150 millimeters (6 in) in diameter and 25 millimeters (1 in) thick, but shape and size vary. Smoke can be detected either optically (photoelectric) or by physical process (ionization), detectors may use either, or both, methods. Sensitive alarms can be used to detect, and thus deter, smoking in areas where it is banned. Smoke detectors in large commercial, industrial, and residential buildings are usually powered by a central fire alarm system, which is powered by the building power with a battery backup. Domestic smoke detectors range from individual battery-powered units, to several interlinked mains-powered units with battery backup; if any unit detects smoke, all trigger even in the absence of electricity.

The US National Fire Protection Association estimates that nearly two-thirds of deaths from home fires occur in properties without working smoke detectors.

What Are The Advantages Of Owning a Smoke Detector?

The biggest advantage of owning a smoke detector is the safety factor. Accidental fires happen all the time, whether it’s from a major appliance or the wiring in your home. You don’t want to put your family in danger by being unprepared for such an unfortunate event. With these devices, you will be alerted when smoke is detected in your home or office, giving you the opportunity to escape the building.

When installed properly and used with fresh batteries, you’ll be protected from events that may occur in other rooms of the home, and you can be alerted while sleeping if something is amiss.

What Are The Different Types Of Smoke Detectors?

You want to make sure that your home or commercial property is equipped with the best detectors, and in order to do that, you have to make sure that you know what types are available to you. There are three main types to choose from, and by knowing the differences in the three, you can pick the best safety product for your home or office.

  • Ionization Alarms – These work with radiation in a chamber. When smoke enters the chamber, the current of this radiation is broken and the alarm notifies you of the smoke by emitting a sound. These respond most to high, fast-burning fires. Ionization smoke alarms can quickly detect the small amounts of smoke produced by fast flaming fires, such as cooking fires or fires fueled by paper or flammable liquids. This type of smoke detector, which is commonly used in kitchens, is prone to nuisance tripping. For example, we’ve all experienced the loud annoying chirping when we leave a cake in the oven too long or add oil to an extremely hot pan. When this happens, people are more prone to disable the alarms.
  • Photoelectric Alarms – These use light beams that, when disturbed by smoke, cause the alarm to sound. These are most effective with slower, smoldering fires. Photoelectric smoke detectors typically respond faster to a fire in its early, smoldering stage – before the source of the fire bursts into flames. These detectors are more sensitive to the large combustion particles that emanate during slow, smoldering fires, which usually occur at night when people are asleep.
  • Combination Alarms – These alarms combine both types of technology to effectively alert you, your family, coworkers, friends, and others on your property when there is a fire.  Some safety organizations have previously recommended these smoke alarms, because they should cover a broad range of fires. However, there are no industry standards for setting the individual sensor sensitivity in dual sensor alarms. This means that a dual sensor alarm could have a non-functional ionization sensor, but as long as the photoelectric sensor works, it still meets the national standards developed by Underwriters Laboratories (UL).

Considerations for Choosing the Best Smoke Detector

Although no one ever wants to think about a fire or other disaster, it’s something that we all must plan for. Being unprepared puts you, your family, and your property at risk, so you want to make sure that your home is protected with smoke detectors. Now that you know a little bit about them and how they work, you may be inclined to just make your purchase. However, before you end up with a product that’s not quite right for you and your home, take a careful look at each product, starting with the evaluation of these four features, to ensure you make a sound purchase.


You just can’t put a price on safety, and when it comes to your smoke detectors, you should be mindful of your budget, but you shouldn’t cut corners or buy a cheap product that could put your property and family at risk. Balance the price of the unit with other features to make a smarter purchase.


As mentioned earlier, there are three different types of detectors. No matter what type you choose, make sure you select a highly-rated unit that functions as it should.


Consider the possibility that a smoke detector in your basement may be difficult to hear from the other side of your home. If a smoke alarm goes off and it’s too far away to be heard, the consequences could be disastrous. Interconnected smoke detectors trigger all smoke alarms to sound off when one of them is activated, alerting you immediately to the presence of smoke somewhere in your home. Most hardwired smoke detectors are interconnected in this manner, but the majority of battery-operated units are not.


How do you want to power your smoke detector? With battery-operated ones, installation is quick and easy, although you have to purchase batteries throughout the years, and many with low batteries make very loud beeping sounds which can be bothersome. With wired units, you don’t have to worry about batteries, but you do need to know about wiring in your home to install them, or you may even have to pay a contractor to install them for you.

Number of Detectors

Sometimes, you may get a better deal purchasing multiple detectors at once. While the investment may seem larger at first, you’ll save by purchasing a contractor’s pack, plus you’ll have enough to evenly distribute throughout your home or office.


The best smoke alarms on the market combine ionization and photoelectric detectors into a single unit. Hardwired smoke detectors don’t have to have their batteries changed out as frequently as battery-operated units and are considered to be more reliable, but if you live in an older home, you may have to hire an electrician to handle the installation of a hardwired alarm system. When it comes to your loved ones and your property, you can never be too safe. You should always be prepared for a fire, even though it’s not something you want to think about happening. You never want to be put in a dangerous situation with effects that could have been prevented. This is why it is a smoke detector is an absolute necessity.

If you want the best protection, add the First Alert 3120B pack to the top of your list. With advanced technology, 360 degree detection, easy installation, and a pack of four that can be used all throughout your home, these detectors are a great way to keep your home or business safe and secure.
