Why Do You Need A Smoke Detector?

A smoke detector is usually a fairly small, disc-shaped object that can be easily installed in a home. And if you do not have one yet, you are making a mistake. For with all the complex circuitry running through our homes, it is not impossible for a fire to break out at some point in time or the other. And that is all the riskier when that happens at night, when you are peacefully asleep in your bed, oblivious to the fact that a fire has broken out in your house. Having a smoke detector installed will let you know of the trouble brewing well in advance, and give you ample time to A) try to get the situation under control, B) alert the authorities in time before much damage can occur, and C) have a sound escape without having experienced any harm. If you think that the smell of the smoke will alert you even if you are sleeping, the loss of oxygen and rising carbon monoxide levels will make you go into a state of unconsciousness, making it impossible to wake up. Best smoke detectors systems are individually battery operated, ensuring that they go off upon picking up a signal even when there is no electricity.

How Do Best Smoke Detectors Work?

Smoke detectors usually come in two kinds- the ones that detect smoke optically, and the ones that utilize ionization method. Both incorporate complex technology to ensure that you are alerted when a fire breaks out. The first category, commonly known as the Optical smoke detector, has an infrared light, which upon detecting smoke, can send a signal to the main detector, thereby making the alarm sound. The other kind, called Ionization smoke detector, which picks up on the smoke being emitted physically from the fire. If you are wondering which one is a better option, then most experts are of the opinion that ionization smoke detectors are more reliable than the former. It is also the latter kind that you will find installed in most homes. However, there is also the dual sensor systems which utilize both methods for optimum effectiveness.

Things To Consider Before Buying The Best Smoke Detector

Buying the best smoke detector for the safety of your home is no joke. However, it isn’t half as complex a choice as you would imagine. Considering that it is an essential piece of equipment to guarantee the safety of your family and yourself, it is imperative that you know exactly the kind that you need for your home. This ranges from everything, like setups to the extra features that you want for maximum protection. So without further ado, let us get into it.

What Kind of Sensors? We have already told you in the section above that there are mainly two types of sensors in a modern system. While preferences are tipped to one side of the scale, both optical and ionization detectors cater to specific purposes. For instance, optical sensors are better and quicker at detecting more smoke while ionization units are best for smaller fires. However, it is incredibly difficult to know which one to pick out because you will not know at the time what kind of fire stands the more chance to break out in your home. Thankfully, however, manufacturers did not wait too long to combine the two together to make what is considered to be the most reliable kind. So we recommend going for dual sensor unit that will be ready to pick up any kind of signal that appears first. The best smoke detectors will also let you know the details of the situation vocally.

Connectivity: If this is your first time installing the best smoke detector system, you need to find out everything about the different types that are available. The most common type of systems is the hardwired sort, which is installed into your home’s electrical system. While these would stand the chance of going inactive when your electricity is down, most units come with a backup battery system to keep them from failing to act. This means that hardwired systems are, in fact, some of the most reliable equipment that you can install in your home. On the downside, they need an expert to be installed, so if you aren’t a pro, you will need the help of an electrician.

For DIYers, there is the option of battery-powered smoke detectors, which are much easier to install because of their less complex power source. Because they are powered by batteries, another notable thing is that their functionality will not be dependent on your home’s main power source. So your alarm will be ready to alert you even when there is a power shortage. However, there is one important thing to note here. Many of the deaths that occur from fire in the US in homes with a smoke detector installed can be blamed on the batteries not being replaced in a long time. So if you choose to go with battery powered units, you should be vigilant of their battery status and any potential failures. Otherwise, one can go with the lithium battery options that need replacing in their entirety over longer periods of time.

There is another kind that is quickly becoming the best smoke detector system according to their buyers. Otherwise known as smart smoke detectors, these are expensive. But these come with dedicated apps that connect the alarm to your mobile device to quickly alert you as soon as it picks up something awry. This way, you will get to know of the situation in your home and alert the authorities even if you are not physically there.

Installation: One of the determining factors in making your selection is the manner of installation. While hardwired models need an expert to mount them, you need to get professional help. But make sure you read the manufacturer’s guide as to where it should be installed and then proceed. Because while traditional smoke detectors are usually mounted onto the ceiling, many of the newer models can be mounted on the walls. This holds especially true for some of the battery operated models and smart models. The installation depends on the kind of detectors a unit uses, so installing one that is meant for wall-mounting up on the ceiling may be the trigger for the lack of prevention.

Where To Install: Finally, when it comes to the best smoke alarms for home, you need to know the basics of installation. The first thing you need to know is that a smoke detector should be placed near or on the ceiling because smoke rises upwards. Another thing to know is that installing your smoke alarm in a place that casts a lot of smoke or steam on a regular basis (kitchen or bathroom) will just end up causing a false alarm. Also, it is a good idea to keep them away from doors and windows, as these may end up misleading the signals.

How Many: This is dependent on a number of factors, such as how big your house is, or how many levels it has. It may even depend on the efficiency of the smoke detector that you buy, or if you are particularly concerned about being alerted as soon as possible. The norm is to have at least one alarm on a floor, with each floor also being armed with at least one system. However, if you have your unit set up in a room other than the one that catches fire, it will take some time for the smoke to travel and thus the system to send you an alert. If that is what you are concerned about, then you may want to install one unit in every room, especially if you have a large house with bigger than average room sizes.
