To do this, you need to know about the types of smoke alarms, factors to consider when choosing one, and how many smoke detectors you need. This article gives all of these information so that you can make a wise decision.
Moreover, it also helps to know about the different kinds of smoke alarms available in the market. You’d be surprised to know that there are alarms that double as a carbon monoxide detector. There are also alarms that are designed for the hearing impaired. Read on to find more about the best smoke detectors for homes out there.
Different Types of Smoke Detectors And Alarms
In order to choose the best quality smoke detectors that you need, you should know about the different kinds of alarm systems first. Basically, there are two major kinds of alarm systems: the heat detector and the smoke alarm. It is important to know the differences between them.
- Heat Detectors
The earliest form of fire alarm is the heat detector. As the term suggests, it is able to “detect” an increase in temperature in a room or space. Once the temperature reaches a specific level, the heat detector sends a signal to alert people about the occurrence of fire.
Heat detectors are most suitable for places where high-temperature fires are most likely to happen. These work best in places where the speed of heat detection is not a major consideration. Moreover, these are often used in places where heat detectors are preferred over smoke alarms.
For most homes, residential smoke alarms are usually favored over heat detectors. This is because smoke alarms are faster than heat detectors when it comes to detecting the presence of fire. And so, smoke alarms are considered as more effective in this case.
- Smoke Alarm
- Ionization Smoke Alarm
This kind of smoke alarm is best for detecting a rapid and raging fire. It contains a very small amount of radiation, which goes through a space in the middle of two electrodes. This space is called the ionization chamber, where there is a constant current passing between the two electrodes.
- Photoelectric Smoke Alarm
This kind of fire alarm is suitable for slow-burning fires. It involves the use of a source of light, a collimating system with a light beam, and a photoelectric sensor. When smoke from a fire reaches its chamber, it crosses paths with the light beam. The smoke causes some light to scatter and reach the photoelectric sensor, which sounds of the alarm.
Once smoke from a fire reaches the chamber, it absorbs alpha particles. The reaction causes a reduction in the ionization process as well as an interruption in the passage of the current. All of these changes trigger the fire alarm.
- Combined Ionization and Photoelectric Smoke Alarm
For best results, some people opt to use an ionization smoke alarm together with a photoelectric smoke alarm. This way, all kinds of fires can be detected, including fast-burning and slow-burning fires. It is possible to install both kinds of home smoke detectors in a single place
Aside from the kind of fire alarm, you should also be familiar with different power sources. For example, there are smoke alarms that are powered by 9-volt batteries. These are not expensive, making them a popular choice among users. But their batteries should be replaced regularly.
In contrast, there are smoke detectors for homes that are powered by 120-volt lithium batteries. These power sources can last for up to 10 years and are most suitable for larger homes and apartment buildings. It also allows the interconnection of multiple smoke alarms together in one place. Some even feature a strobe light, which is designed specifically for the hearing impaired.
Regardless of the type of alarm or power source, you should be ready to maintain and replace your devices regularly. For best results, conduct a detector test every month to ensure that it works. What’s more, consider changing the batteries at least once a year. This way, you can prolong the life of your value smoke detectors.

How to Choose a Smoke Detector
Once a fire starts, it could spread very quickly, giving you only two minutes or less to evacuate your house. But if you have installed the right kind of smoke detector, your chances for evacuation and survival increases. And so, you should learn how to select the best residential smoke alarms for your home. Here are some of the things that you need to consider.
- Type of Smoke Detector
As cited earlier, there are different types of smoke detectors, each of which has its own strengths and weaknesses. These types include ionization smoke alarms, photoelectric smoke alarms, and dual-sensor smoke alarms.
The first type of smoke alarm “ionizes” the air using a small amount of americium 24, which is a radioactive material. The process sets up an electric current, which gets disrupted the moment smoke comes in. This triggers the alarm, which comes in handy in detecting fires that occur rapidly. These include fires that involve paper, grease, and most arson cases. Notably, some of these alarms are fitted with carbon monoxide detectors.
The second type, photoelectric smoke alarms, feature a tiny, pulsating light. As soon as smoke enters its chamber, this light scatters and reaches a sensor, triggering the alarm. This type of alarm is more suitable for the detection of slow-burning fires, including those involving electricity, clothes, bedding, and furniture. They are more expensive than ionization smoke alarms, but they are less likely to be triggered by accident.
The third type of smoke alarm is actually a combination of ionization and photoelectric alarms. They can be installed as separate units or integrated into a single device. In any case, having both types enables you to detect both fast-burning and slow-burning fires. This option may cost more but it provides a greater amount of safety for your home.
- Power Source
As mentioned previously, you should also consider the power source of your smoke detector. Most smoke alarms operate on 9-volt batteries, such as AA and AAA batteries. Your should replace these batteries regularly, at least once a year.
On the other hand, some of the best smoke alarms operate on lithium batteries, which can last for up to 10 years. Still, there are smoke alarms that you can plug into electric outlets. These often come with back-up batteries, which you can use in case of a power outage.
- House Size
The size of your house also plays a role in the selection of smoke alarms. Ideally, there should be one alarm for every room, including your attic and basement. Smoke alarms should also be installed in every hallway, in between the rooms.
If your house is huge and you need several smoke alarms, consider wiring them together. This way, when one alarm sounds, the others do the same. Even if you and your family are in separate rooms, you will hear the alarm at the same time and evacuate with safety.
Moreover, when installing a smoke alarm in the kitchen, look for a photoelectric alarm instead of an ionization alarm. The latter is more sensitive and could go off even when you are just cooking. You would not want to be bombarded by false alarms every time you use the kitchen stove!
Regardless of the type of alarm that you buy, make sure that it has proper certification. Look for a sign or logo indicating that the unit has been tested and certified by an authority, such as Underwriters Laboratories, Inc. Aside from initial testing and certification, these laboratories also hold follow-up tests to make sure that alarm manufacturers follow their standards.
Before you buy a smoke detector, ask the seller first if there is a way to test it. This way, you can test your smoke alarm every month to see if it is working. There are smoke alarms that include a “test” button that makes it easy for you to check. You can also look for alarms that come with a remote control so that you do not have to climb up a ladder just to check every time.
Choose a smoke alarm that is easy to clean and maintain. For instance, there are models that come with a removable cover, which you can take off whenever you need to clean them. If you do not vacuum your smoke alarm at least once a month, the dust could accumulate on the sensors. Over time, this could lead to annoying false alarms.
- False Alarms
Speaking of false alarms, our automatic response would be to turn them off as soon as possible. This means that you should look for a smoke alarm that you can turn off easily without having to disable the whole unit. Otherwise, you will need to remove the batteries altogether and have to put them back in every time there is a false alarm.
- Special Features
Do you or anyone in your family have special needs? If so, you might want to consider buying a smoke detector that suits your needs. For example, there products that are designed for the hearing-impaired. Aside from the sound alarm, these include a visual signal so that everyone can be alerted when it goes off.
How many smoke detectors do you need?
If you are wondering how many smoke detectors you need, check the number and location of bedrooms in your house. This is important, because even if everyone is sleeping, you would want them to be woken up as soon as the alarm goes off. You do not have to put them in the bedrooms themselves, but rather in the hallways in between rooms. Make sure that they can be heard in every bedroom in the house.
If your bedrooms are located on different floors, make sure that there is a electric smoke detector on each floor. In any case, you can always ask your building inspector for tips on setting up smoke detectors. You may also get in touch with your local fire department for more information about the best home smoke detectors and their possible locations.
