A smoke detector is a fire-fighting device. It is installed on the ceiling or wall and has sensors that detect smoke that, due to its composition and density, is considered dangerous.
When a possible fire occurs, smoke rises to the top, the smoke detector detects it , and sounds an audible alarm, alerting everyone nearby.
It's a simple and very practical way to alert us that there's a fire in our home and allow us to respond quickly. This considerably reduces the risk of a small mistake turning into a major blaze. We already know that fires can spread out of control in just a few minutes, so it's very important to detect a potential fire before it's too late.
We offer a selection of the best, most efficient, and high-quality smoke detectors for greater peace of mind at home.

Google Nest Protect White
This device is from Google Nest, and if you want to have a more technological level at home, this smoke detector is perfect for you.
It features a Spread Spectrum Sensor to detect smoke and fast-burning and slow-burning fires , and the CO sensor will let you know exactly where the toxic carbon monoxide is. It uses two wavelengths of light to detect smoke.
It can be silenced from your phone , it checks automatically, and it lasts up to 10 years. It also tells you what the problem is.
Google Nest Protect sends you alerts to your phone if there's a problem at home. You'll receive a message if the detector is triggered, if the batteries start to run low, or if the sensor isn't working.
If something happens in your home, all your Nest Protects speak together to tell you what's happening and where the danger is. Nest Protect 2 checks for any issues over 400 times a day.
It is equipped with a steam control to prevent it from exploding during a shower and a pilot light to illuminate at night.
In addition, it is compatible with iOS and Android.

Chuango SMK-500
This photoelectric smoke detector works by detecting smoke particles in the environment. It is wireless with an internal antenna and built-in siren.
Thanks to its special design and photoelectric signal processing, it avoids false positives due to dust or other interference, focusing on the detection of smoke caused by visible or hidden fires.
When the Chuango SMK-500 detects smoke, it sends an alert to the panel , triggering the alarm. It also has a built-in siren that sounds upon detection, triggering the initial warning.
It has a simple installation on the ceiling, compact and aesthetic format.
It features a 433 MHz wireless connection to the panel, with a maximum range of 100 m, and a high-power internal siren: 85 dB/m. It also has a wide detection range of 20 m².
It resets automatically after an alarm and when the smoke concentration disappears. This detector alerts you when the battery is low.

ELRO FS1805
This smoke detector has an optical smoke sensor for reliable protection without radioactive substances.
Its installation system is not with screws, but with magnetic adhesives, included in the kit.
ELRO FS1805 Smoke Detector , has a test button for functional testing and a low battery indicator.
This detector will alert you in the event of serious fires. It is especially safe and environmentally friendly, as it features an optical smoke sensor that regulates the airborne smoke particles and eliminates radioactive substances.

Netatmo NSA-EC
Netatmo smart smoke detector compatible with iOS and Android.
With this detector, you can receive notifications on your mobile phone if smoke is generated inside your home. It will also produce an 85 dB audible warning.
Alerts are delivered in real time, so you can receive them even when you're not at home.
This smart smoke detector features a test button and an audible warning if the batteries run low.
It's very easy to install, just install the wireless smart smoke detector on the ceiling and download the app.

SEBSON 6x
SEBSON Smoke Detector is a photoelectric detector that includes a 10-year long-life lithium battery and magnetic mount.
Every 30-40 seconds, the smoke detector performs a self-test. This can be indicated by a brief flash of the LED.
With Sebson 6x, as soon as smoke enters the device, a loud alarm will sound.
Its temperature range is 0°C to +45°C, and its alarm volume is ≥85 dB(A) within 3 meters.
It has the following certifications: EN 14604, NF
As for the power supply, it has a DC 9V battery (lithium battery: CR9V).
Finally, the detector comes with a magnetic mounting kit , which can be mounted quickly and easily without the use of tools, screws or plugs. Temperature range from 0°C to +45°C

Types of smoke detectors
Smoke detectors have different detection systems and functions, which makes them different from one another.
Ionic smoke detectors
Ionization detectors are sensitive to the small particles and moisture present in the environment during a fire. They operate by ionizing the air if smoke enters the detection chamber; the detected elements may be invisible to the naked eye.
These types of detectors are generally installed in the chemical industry, as they are more sensitive to rapidly growing fires or those with invisible smoke.
Optical or photoelectric detectors
Optical detectors detect the change in light produced by smoke through a lens, generating an alarm. These detectors can be infrared or point-type lenses.
These are point-detection systems, and there are two types: analog optical detectors and digital ones , which are placed in ventilation ducts to detect the presence of smoke in large rooms or in the building in general. They are commonly used in homes, shopping centers, supermarkets, prisons, and warehouses, among others.
They're a much simpler solution and also offer high product durability. Simply check the sensitivity and properly install the detector.
Thermal detector
The thermal detector is a fire detector , as it works by the melting of an element when a high temperature is reached. They are usually activated around 68°C and can only be installed in rooms up to 7 meters high.
They are generally used when a conventional smoke detection system cannot be used, for example, in kitchens or garages.
Radiation detector
The radiation detector is also a fire detector. It detects, using various electronic components, the presence of radiation generated by a fire. They are installed only in open spaces or places with very high ceilings, and produce a late alarm.
Conventional detectors
These detectors detect smoke, fire, heat, or any combination of these, and indicate if there is an alarm in the different detection zones.
Conventional addressable detectors
These systems are capable of detecting the presence of heat, smoke, or fire, and they also indicate whether an alarm exists for each detection element, not for each zone. Therefore, they are more precise systems that allow for better response by emergency services.
Smart detectors
Smart detectors are capable of quantifying the presence of smoke , temperature levels, fire, or combinations of these elements and react according to a pre-programmed protocol.
Factors to consider when purchasing a smoke detector
Smoke detectors can save us from a home fire. It's a fairly inexpensive safety measure and worth considering to reduce risks and prevent a potential accident.
You need to pay attention to certain aspects to buy the model that best suits your needs.
Alarm and power
Once the detector detects the presence of smoke in the room, the corresponding alarm is activated.
It is important to take into account the power of the alarm, which is measured in decibels , and the distance will have to be assessed to determine what power we will need.
A conventional alarm typically has around 90 decibels . If the space being monitored is farther away, a higher decibel level is recommended.
Facility
The smoke detector can be installed on the ceiling or on the wall , and for proper installation, you need to know the height at which you intend to mount it.
Mounting will depend on the weight of the detector. Lighter smoke detectors can be installed with adhesive , although it's a good idea to check the quality of the adhesive.
If, on the other hand, the smoke detector is too heavy to install, you will need plugs and screws.
Test the detector and change the batteries regularly.
Smoke detectors have an indicator light that lets you check if the device is working properly. It's a good idea to check your detector periodically.
Although wireless smoke detectors consume very little power, it is very important that you change the battery periodically to ensure the device continues to function properly.
Another precaution you should take when you have this type of detector at home is to have spare batteries so you can change them immediately if necessary.
