Recent Buyer Reviews On First Alert Onelink Safe & Sound with Alexa

This is a good product with excellent Alexa integration that is why bought it, However, night light, speaker. The quality of the speaker is fine.

It is a bit quieter and you get an equalizer with a balanced setting and a default setting. The alarm itself is a good general smoke alarm but it is in-line with other good products.

OneLink app is also a bit difficult to use. In addition to a minor dare of trying to sync all the alarms on one floor, it would sometimes be very easy to accidentally miss the “Alexa integration” button on the bottom of the GET STARTED.

Then I have to reset the smoke detector again to get it up to speed. Overall many customers recommended it.

Very easy to install as it easily fits into the frame already existing from the previous version. It will last about 10 years, as it will have to be replaced due to very loud and nerve-damaging chirping.

You will be given some wide-gap, intermittent warning chimps a month or two before replacing it. Once installed and hardened, we had no issues like irregular beeping as we had done before. It is an easy place to reach and I think we are safe. Most buyers highly recommended

Wireless smoke detectors

Currently, there are many smoke detection systems on the market. They use various matched transmitter and receiver models to achieve excellent frequency stability for signal transmission.

Whether you use a photoelectric or ionization camera, the key element to detect the presence of smoke is sensitivity.

Some of them have an inherent rate of increase and heat detector. Direct and lateral configuration of video cameras is also available with glass break detectors and panic transmitters.

In addition, a low standby current in sleep mode will save power. There is a new model that works with very high sensitivity. A patent for the system “Artificial Intelligence” is known as a classifier.

This ensures that the system operates at the highest safe sensitivity to a warning of problems previously considered possible. The classifier also controls the monitoring of dust filters to prevent partial performance, reducing system performance.

The system can be connected to a computer and detailed records of historical smoke levels can be viewed showing date, time, and alarm thresholds.

In addition, technological improvements in the use of microprocessors in fire alarm systems have led to the development of new smoke detector concepts.

Wireless smoke detectors that communicate with each other

You do not have to worry about interference with other wireless devices or signals, as the products fully comply with international standards.

A commonly used radiofrequency is 433 MHz that is not attenuated or weakened through walls or floors or other ordinary construction materials. This frequency spectrum has less traffic and therefore less interference.

Types of smoke detectors

A smoke detector typically has three types of sensors. These are the main differences between the three.


The Ionization smoke detectors use radiation and a chamber to detect smoke. With a blazing fire, ionized radiation helps to detect small amounts of smoke in the air. When a cloud of smoke enters the sensor chamber, a stream of ionizing radiation is interrupted, causing an alarm to sound.


Photoelectric smoke alarm sensor uses ray light to detect smoke. When smoke particles are hung in the air (with a latent fire), the particles scatter the light beam into the sensory chamber, triggering an alarm.

Dual sensor

Dual sensors include photoelectric and ionization sensors. The safest smoke and fire detection devices, because they detect both blazing fires and small blazing fires, these dual-function sensors are unlikely to have any fire-related hazards.

Factors To Consider Before Buying A Wireless Smoke Detectors That Communicate With Each Other

Once smoke and carbon monoxide is detected, life expectancy increases to 50%, making it worth the investment.

When deciding which wireless smoke detector is best for you and your loved ones, think about these features and what benefits you want to achieve with your purchase.

Multifunctional Device

The best smoke detector can detect smoke particles, flames, and carbon monoxide. A Multifunctional alarm for wired smoke detectors can save your battery life or the energy of your home.

Combined smoke, fire, and carbon monoxide detectors are easier to find than ever.


If the lights in your house go off, then you still need to know if there is a fire or smoke emergency. Wired smoke detectors must have a backup battery or some other backup power source to operate.

 If the power goes out, take your smoke detector. Battery-powered smoke detectors must have a test button or a chirp when the battery starts to run out.

Smart Device

While classic ionization and photoelectric smoke detectors are useful, smart smoke detectors are at the forefront of fire protection.

They communicate via the app and send an alert to your phone or another mobile device when the alarm sounds. Smart alarms can also communicate with each other, so you’ll know where the fire is when the alarm goes off. The only downside is that smart devices are more expensive.

Check battery

Dead batteries are responsible for 25% of smoke detector failures. Additionally, nearly three out of five fire deaths in the home were with malfunctioning smoke alarms or no smoke alarms.

If this doesn’t work then a smoke detector won’t do you any good, so be sure to check your battery every month and use the “test” button to ensure proper operation.

Keep clean

Dirt and debris interfere with the sensors on your smoke alarm. Dust buildup can cause incorrect alarms or delay detection during an emergency. Whether you have a photoelectric alarm or an ionization detector, regular cleaning will keep your smoke Alarm on.

High Mount

Smoke rises. It is important to keep your foot about a foot away from your roof and ten feet from the cooking areas.

For vaulted ceilings, avoid placing a smoke detector at the “tilt” of the roofline. Instead, mount a fire alarm three feet below the roof so that they can read the smoke correctly.

Get connected

Hooking up your smoke detectors ensures that everyone in your house knows about the emergency. You can easily establish a connection and sirens will ring throughout the house using each of your fire alarms.

Some additional steps are required to set up and test, most wireless smoke detectors will require that you pair them together so that they can transmit and receive signals to and from each other.


We checked out the best wireless smoke detectors no doubt that would be perfect for your needs. With so many options available, it can be a little difficult to decide which the right selection is.

 Instead of buying one first, think about what others have said about the brands and models they have purchased.

When we provide you with useful information for your shopping experience, we want you to check and check other verified buyer feedback.

Go ahead and dig deep into the wireless smoke detectors that interest you the most. Editor’s best recommendation is First Alert BRK 3120B
