How Do Smoke Detectors and Alarms Work?

All of the best smoke detectors and best smoke alarms work using one of two techniques. They are either photoelectric detectors, or they are ionization detectors.

How Do Smoke Detector Works?

Before you can buy the best smoke detector for your home, you need to understand the difference between a smoke alarm and a smoke detector.

A smoke alarm is an all-in-one device. It has a detector that can sense smoke and then produces an audible alarm to warn you that smoke has been detected.

A smoke detector is designed to detect smoke. It triggers a building’s fire alarm system and may have a visual indicator showing that smoke has been detected. It must be connected to a building’s fire system. It is not a standalone unit.

It is essential that you understand the difference between these two devices when you are reading smoke alarm reviews and choosing what you will install in your home.

What Is a Photoelectric Smoke Detector?

In a photoelectric detector, a beam of light travels from a light source straight across the detector. It is designed to miss the sensor. However, when smoke enters the chamber, light particles scatter, resulting in some of the light hitting the sensor and triggering the alarm. These are the best smoke detectors for home when the fire is smoky and caused by things like mattresses.

An ionization smoke detector has an ionization chamber. It responds to small amounts of smoke caused by flaming fires. Inside the detector there is around 1/5000’s of a gram of a radioactive element called americium-241.

The ionization chamber has two plates with the voltage going across them. When smoke enters the ionization chamber, the current is disrupted because smoke particles attach to ions, rendering them inert. When there is this a drop in the current between the plates, the alarm is triggered.

Smoke alarm reviews speak highly of ionization smoke detectors because they are inexpensive and effective.

How To Choose A Smoke Detector

There are a lot of smoke detectors on the market, and each one of them promises that they are the best smoke detector you can buy. However, since your family’s security is serious to you, you are not just going to trust what a manufacturer says. Instead, you want to do your own research by looking at smoke alarm reviews. The following are some things to consider when choosing a smoke detector and which smoke alarm to buy.

Determining Which Smoke Alarm to Buy

With so many features, it can still be challenging to determine which alarm or detectors are going to meet your needs. A lot has to do with your home. If you live in an older home that has older wiring, it might be too expensive to have an electrician come in, bring your wiring up to spec, and then install a hardwired unit.

Conversely, if you live in a newer home, it might be a simple thing to use existing wiring to get the benefits of a hardwired unit.

A multifunctioning unit may be a good idea if you have fuel-burning appliances in your home, such as a natural gas furnace or water heater. If you do not have these devices in your home, then it is unlikely that you’re going to be exposed to carbon monoxide, and so a multifunctioning unit may not be right for you.

Of course, this is not all useful electronic devices that can help keep your home safe. We also recommend you to buy a video doorbell or wireless video doorbell.

Smoke Detector Sensor Types

When determining what smoke detector to buy, it is beneficial to learn about the types of smoke detector sensors you can choose from.

Photoelectric Sensors: These sensors are designed to detect slow burning fires that create a lot of smoke. The smoke interacts with light produced by the light source and causes it to trigger the sensor, which in turn activates the audible alarm.

Ionization Sensors: These identify fast burning fires that may produce more fire than smoke. They have two metal plates with a minimal amount of radioactive material that ionizes the air. As smoke passes through the device, the ionization is interrupted, triggering the alarm.

Dual Sensors: A dual sensor alarm has both photoelectric and ionization sensors. These are the best smoke detectors you can buy because they are triggered with any sign of a fire.

It is recommended that you purchase a dual sensor alarm. This is because you have no way of knowing in advance what type of fire may start in your home. With a dual sensor device, you know that you have all of your bases covered.

Factors to Consider When Buying a Smoke Detector

There are other features that you should consider when determining which smoke detector to buy. While not all of these features are necessary for the detector to be effective, they do increase the performance of the unit and the chances of you getting out safe in the event of an emergency.

Determining the Power Source

You have three basic power source options. You can opt for battery power, hardwiring, and a wall plug-in unit. Most hardwired devices have the option for a backup battery. So even if the home’s power fails, you still have battery power to rely on.

With a battery-powered unit, once the battery dies, your unit stops working. Many companies are producing lithium batteries that will last the life of the alarm, so you do not have to worry about changing batteries every couple of years.

Battery Backup

The battery backup in your hardwired alarm will warn you when the battery is getting low. Depending on the unit you select, it may chirp, there may be a LED display, or you may receive a low battery voice message.

Interconnectability

Some alarms come with the option to link them with other alarms in the home. So if the smoke alarm in one room triggers, all of the alarms in the home will sound. Many of these units provide a verbal alert indicating in which room the alarm was triggered.

Homeowners who have a multilevel home may want to consider purchasing an alarm or a detector with this feature. In a small single level home, this interconnection may not be necessary.

Digital CO Display

Most carbon monoxide detectors are designed to sound an alarm once the CO levels reach 70 ppm. However, people with certain conditions, such as cardiovascular issues, children, or women who are pregnant may be harmed with as little as 30 ppm of carbon monoxide in the home.

The digital display will help you see if the carbon monoxide levels in the home are rising, even if they have not reached a level that would trigger the alarm.

Hush Button

When an alarm triggers a false alert, maybe because you are cooking or barbecuing, it can be very unnerving and frustrating. In times past, the only option was to disable the unit by disconnecting it from its power source or unplugging the battery.

The downside of this is that it is easy to forget to re-plug in the unit or reconnect it to its power source. Hush buttons temporarily deactivate the unit and then reactivated after a set period of time. Some units have remote control hush buttons or hush buttons that can be activated from your mobile device.

Strobe Lights

Strobe lights are an awesome feature, especially in homes where there are hearing impaired individuals. Some units come equipped with strobe lights, whereas others include the option to add on a strobe light.

Voice Alarms

Most people understand how easy it is to sleep through the beeping of an alarm. However, it is easier to wake up when you hear someone’s voice. This is the principle behind alarms that have a voice alert. Some even have the option of allowing the homeowner to record their own voice or have someone else record their voice so that it can sound in the event of an emergency.

Safety Lights

In the event of an emergency, it is easy for confusion to ensue. Smoke alarms with safety lights provide a safe path of illumination. This could mean the difference between life and death if an emergency takes place at night.

So what is the best smoke and carbon monoxide detector? The answer is going to vary depending on your needs. If you have a home with high ceilings, then a hardwired unit or a unit with a lifelong battery may work the best. If you have a large home, then consider getting a unit that connects with the other detectors in your home.

Homes with hearing-impaired individuals would benefit from detectors with a strobe light, and homes with children may benefit from detectors that include safety lights and voice alarms.

Smoke Detector Installation And Maintenance

You understand how having a smoke detector in your home can save your life and the lives of your family. That’s why you are reading this guide. The National Fire Protection Association stated that casualty rates in homes with working smoke detectors were 50 percent less than that of homes without working detectors.

The key phrase in this sentence is ‘working.’ If the fire detector in your home is not functioning or if it is not properly located, it will not provide you and your family the protection that you need. It is essential that you take the time to learn about smoke alarm installation and maintenance.

How Many Detectors Will You Need to Install?

The answer is going to vary depending on the size and layout on your home. It is recommended that you at least have one detector on every level of your home. It’s even better if you can have one detector inside every place in your home where people sleep. This includes basements and attics.

Having a smoke detector for kitchen use is a must. Experts recommend that you put one either just outside the kitchen or just inside the kitchen. If you find that your kitchen smoke detector is setting off a lot of false alarms, get one that has a hush button. The hush button will minimize the unit’s sensitivity for a short period of time, allowing you to cook without irritation.

Don’t Procrastinate

As we mentioned, just purchasing a smoke alarm is not enough. Install it as soon as you buy it. There is no reason for your family to go even one night without the protection that detectors provide.

Your detectors should be placed on a flat wall or ceiling. They should sit in the center of the room. If you opt to install your unit on a wall, it should be no more than 12 inches from the ceiling.

Special care should be used when installing hardwired units. If you are not familiar with electrical wiring, it is best to leave the installation up to professionals.

Test and Then Retest

As soon as you install your device, you and your family should go through and activate each device individually. This serves two purposes. First, it helps you make sure the devices are actually working. Second, it familiarizes your family with the do sound of your smoke detectors. During this initial test and installation, take the time to familiarize your family with exit routes and plans of emergency.

Regular Maintenance Is a Must

There are a lot of units that tout their ability to perform self-diagnostics. However, we recommend that you take the time to manually test your devices on a monthly basis. This will allow you to make sure that the sensors are working well and that the detectors are set to an appropriate volume.

Don’t Let Your Batteries Die

Many of the units that we reviewed come with lifetime batteries, but some do not. Check the manufacturer’s guidelines for your unit, and then schedule periodic battery changes. A good rule of thumb is to replace your non-hardwired unit batteries every single year. The manufacturer’s guide will walk you step-by-step through how to replace battery in smoke detector.

Keep Your Unit Clean

Take the time to clean your unit, removing dust and pollutants every single year. This is especially important when discussing a kitchen smoke detector. Since you will be regularly cooking and creating smoke and steam in the kitchen, it is easy for these detectors to become dirty, and this can impede their performance.

Cleaning a smoke detector is a simple process. Simply take the device off the wall or ceiling, disconnect it from the power source, remove the external casing, and then use compressed air, a dry cloth, or a vacuum to remove any dust that has accumulated. It is not recommended that you use liquid sprays or cleaners as these can interfere with the device’s sensors.

Smoke detector maintenance can seem a bit overwhelming and some may consider it to be a nuisance. However, families who took the time to maintain their unit and as a result were able to escape a dangerous situation unscathed were happy that they did the work. The opposite is also true.

To help you remember to do maintenance, we recommend that you schedule your monthly and annual maintenance to coincide with a date that you will always remember.

Fire safety and smoke detector maintenance are part of being a responsible homeowner. Hopefully, you will never have to deal with a fire, but if you do, you are going to be thankful that you and your family were prepared.

Of course, home safety is very important. But it’s also important to take care of your lawn, our best battery-powered weed eaters will help you with that.

Smoke Detectors FAQ

 Most manufacturers recommend replacing the smoke alarm every 10 years. Why is this recommended?

The NFPA 72 National Fire Alarm and Signaling Code states clearly that smoke alarms should not be used for more than 10 years from the date they were manufactured. From this point, an alarm cannot to be counted on to provide the needed protection.

Are there any areas where I should not install a smoke detector?

Smoke detectors should not be installed inside your kitchen. They should be installed just outside the kitchen. This is also true of any other place in your home where dust, fumes, or steam is likely to collect. If a smoke detector was installed right outside of the bathroom, steam generated during a hot shower may trigger it inadvertently.

My home alarm system has a smoke detector. Is this enough?

The smoke detector that comes with your alarm system is going to be as good as one you will purchase for yourself. It is good to verify that you have enough detectors installed. If not, purchase more. As a rule of thumb, you should have detectors outside of every bedroom, at least one detector on every level of the house, and detectors inside bedrooms.

 Do I really need to test my smoke alarm every month?

Yes. Monthly testing will allow you to guarantee that your batteries are still working in a battery-powered unit and that units that are daisy chained together have not had any wire damage done by either an animal or wear and tear. Most units have a very simple test button on them and can be tested in just a few seconds.

Summary

There are a lot of options available when selecting smoke detectors. You do not want a smoke detector that is sub par, that has a lot of false alarms, or worse yet that will not trigger when you need it to. All of the units that we have mentioned have stellar smoke alarm reviews and have worked well for many people.
