The smoke alarm is a device designed to detect the presence of a fire principle inside buildings. Smoke is formed from products deriving from inefficient combustion, which generates a series of particles that remain suspended in the air.

These devices are able to capture particles and other gases, signalling their presence with acoustic warnings. To decide which smoke detector is best suited to your needs, you will need to take into consideration some fundamental aspects.

To facilitate your choice, we have chosen the best detectors available on the market today, we have searched for all the information available, analyzed the studies and consulted the reviews.

Things to Consider Before Buying Firex Smoke Alarm

Smoke detectors are simple equipment, elementary to install, always very cheap and, most importantly, they were born to save lives.

Choosing which one is most suitable for your home can be complicated, given the countless variety of models on the market. To help you, we have answered the most common questions about these devices.

What Is a Smoke Detector?

A smoke detector is an alarm mechanism that detects the presence of smoke in the air and emits an acoustic signal to warn of the danger of fire in a house.

The detection method is divided into two categories: ion detectors and the other from optical sensors. Both manage to capture the fumes deriving from combustion, although the ions are more sensitive.

When fire detectors are connected to a visual or audible alarm control unit, they are called smoke detectors. Unlike a single device that receives energy through batteries and acts independently is called a smoke alarm. In this article, we have chosen the term revealing.

What Is the International Regulation on Smoke Detectors?

The quality standard used for the international production of smoke detectors is ISO 7240-7. In the United States, they are produced using UL268, while in the European Union the manufacturing standard EN 54 part 7 is followed, created by the European Standardization Committee (CEN).

What Kind of Smoke Detectors Are There?

The market offers a wide variety of smoke detectors which, as we have seen, can be divided into photoelectric detectors and ion detectors.

This division is, however, a bit generic, given the existence of other types of detectors such as those sampling and others more or less sensitive, but almost always all valid.

What Is Third Party or Independent Laboratory Certification?

All smoke and fire detection products must be approved by an independent laboratory (a third party) which certifies the minimum safety and quality of this equipment, designed to save lives. The third-party certification guarantees compliance with the minimum production requirements.

The certification will demonstrate not only the quality of the equipment but also the provision of a management plan by the production company that guarantees that all the products manufactured are of the same condition.

To obtain certification, there are several recognized and prestigious laboratories all over the world.

What Are the Basic Principles for Installing Smoke Detectors?

It is customary to install the smoke detector in the kitchen, although it is often counterproductive because of the mechanism that activates it even in the presence of cooking fumes, which is why over time it ends up being removed.

It is better to install it in rooms outside the kitchen, better between the kitchen and the living room, on the ceiling and in the centre, so that it acts in the best way.

To help you better understand where and how you can install your smoke detector, we have created a list with some basic principles regarding installation:

  • If the ceiling temperature is higher than 37.8 degrees Celsius, a model approved for higher temperatures must be chosen, so that this is not triggered by heat.
  • Avoid installing it in the kitchen. The smoke caused during cooking will activate the alarm, causing false signals.
  • Do not install the detector in a room with intense vibrations.
  • The effect of humidity can affect its operation: do not install it in corners or in damp places.
  • We recommend installing a smoke detector every 60 m2.
  • If the ceilings are too high, several detectors should be installed, in order to counteract the “smoke cone” effect.

What Kind of Maintenance Does a Smoke Detector Need?

Smoke detection systems require proper maintenance to ensure their operation. Photoelectric detectors need more care than other models since they have a camera with two optical devices that capture changes in light, and that must always be kept clean.

It is essential to clean the smoke detectors thoroughly as they can be damaged by dust, moisture and dirt build-up. In these cases, the alarm could be activated incorrectly.

At the same time, you should check the battery life, which you can do thanks to the test buttons usually included to facilitate the readings.

What Drawbacks Can a Smoke Detector Have?

Smoke detectors have few drawbacks. They are indispensable tools that can save your life, even if with less advanced and poor quality models, false alarm episodes can occur. The smoke from the kitchen, a cigarette or even the steam from the bathroom can trigger detection.

This may be due to the poor quality of the detector, or due to incorrect installation. Other problems can arise during the same setup since some models incorporate all the necessary material while others do not.

Batteries can also cause problems in cases where they last a short time or if they require periodic checks.

Where Can I Place a Smoke Detector?

The size of the home or room where you want to install the detector determines the number of devices needed, but other factors are also essential. Only some professionals can fit specific models.

In addition, any element that may hinder its correct operation must be removed from the vicinity of the device. Below we show you a list with some tips for installing your smoke detector:

  • Homologation. Firstly, we would like to inform you that you only need to purchase approved smoke detectors.
  • Electrician. Alarm systems connected to the mains must be installed by a certified electrician.
  • The Best Place for Installation Is in The Centre of The Ceiling. The reason is that the air does not circulate in the corners.
  • Pay Attention to Space Around the Device. At least 30 centimetres of space must be left from any decorative object.
  • Avoid False Alarms: It is not convenient to use a smoke detector in the kitchen. Instead, choose a temperature detector that can immediately detect sudden changes and warn you in case of fire risk.
  • A Detector Should Be Installed in Every Room: Especially if the bedroom doors remain closed at night, but it is essential to do this even in the case of multiple smokers.
  • Pay Attention to The Location: You should not install them near appliances, air conditioners or hot vents.

What Should I Look for In a Smoke Detector?

The quality of the smoke detectors depends on greater effectiveness and some additional features. For example, a pause button is usually included, which allows you to stop the alarm when it is activated by mistake. It is also important to have battery level test systems and to check their operation.

The most common accessories and features you should look for in a functional smoke detector are:

  1. Mute button with remote control. To silence the most annoying alarms.
  2. Safety lights that provide illumination during the alarm.
  3. Security alarm system with transmission of the signal to a central monitoring station.
  4. Intercommunication of devices via cabling or wireless system so that all detectors are connected to each other.
  5. Application to receive notifications on your mobile phone.

Purchase Criteria

There are numerous brands and various models of smoke detectors on the market today. Choosing the one that best suits the needs of your home is not easy at all. To help you choose such an indispensable appliance, we have compiled a series of purchase criteria that we believe are most important:

  • Functions
  • Supply
  • Connectivity
  • Silent function
  • Guy
  • Installation
  • Sensitivity
  • Alarm

Functions

Most smoke detectors on the market serve to detect various types of fires. These appliances react to the particles present in the smoke and emit a signal.

As a general rule they usually detect nothing but smoke, however some may react to the steam of boiling water or that of a bathroom, but this will be a weak quality signal.

Other devices have extra features like gas detection, such as CO2. These appliances are more advanced and can detect dangerous gas leaks. There are also models incorporating LED lights that are activated by motion detectors and are used to make light during the night.

Supply

Usually, these devices incorporate 1.5 V AA or AAA batteries. They are low-power equipment, so they can work for years without having to change the battery. Some more advanced models have independent cells and operate for up to 10 years without interruption.

The problem with smoke detectors with an independent battery is that it cannot be recharged, so when it goes out after ten years of life, the entire device will have to be changed. Most appliances will notify you at least 30 days in advance before turning off.

Connectivity

The ideal is to choose a smoke detector that can be connected to other devices. Some models relate to each other, and there are also some that can be synchronized with different types of sensors (gas or particles), in this way all the units in your home will sound an alarm when one of these is activated.

Most smoke detectors on the market do not require any type of wiring for installation; however, some models must be connected to electricity or a telephone cable in order to send the notices to an emergency centre. These models are more expensive and need to be installed by professionals.

Silent Function

To silence an annoying or simply incorrect alarm, just have a silence or pause button. These buttons allow you to stop the signal without having to turn off the device, an essential function since it avoids the problem of not remembering when to connect the device and that this does not work in cases of need.

You will find this function in all or most of the smoke detectors on the market today, along with others such as recalibrating the sensor or checking the battery status. These buttons are usually large in size and can be pressed from the ground, for example using a broom.

Guy

As we have seen, smoke detectors can be mainly optical or photoelectric. The previous work thanks to a lens that detects the changes generated by smoke on the light and are the most used and economic models.

They are present in many homes, do not require installation, rarely need maintenance and can be purchased for less than 20 euros.

Ionization detectors are sensitive to moisture and tiny particles that remain suspended in the environment during a fire. They are usually quick and also cheap. There are also mixed models, recommended because they also detect CO2 and gases, offering much more complete protection to your home.

Installation

Among the aspects that often create doubts for users is the possible difficulty in installing a fire detection system in your home.

Although it depends mostly on the type of detector, in reality, the installation is always straightforward. You don’t even have to screw the sensor to the ceiling, just attach it with any type of tape.

There is also no need to configure anything. You just have to turn it on and check that it works well (you can do it by burning a sheet of paper in a safe place, like in the bathtub or on the sink). If you have chosen a more complex system, you will need to contact a professional electrician to install it.

Sensitivity

We speak here of a complicated factor. A too sensitive detector will be triggered in the presence of any smoke, soon becoming a problem since it will also be activated with the smoke produced during cooking, with that of a cigarette or even with the steam from the bathroom.

The constant false alarms will cause you to get tired of your detector, and eventually, you will have to disconnect it and set it aside.

The best smoke detectors, although equipped with high sensitivity and ability to detect fumes very quickly, do not trigger in any circumstances.

Not being able to ascertain the sensitivity quickly before purchasing, we advise you to read user reviews. If they say it activates too immediately or does not activate when needed, don’t buy it and vice versa.

Alarm

The alarm is one of the essential elements of the detector. Together with the detection system, the alarm will be decisive, as it represents the only way to know if there is a fire in your home. Discard any model with weak and inaudible signals: it is essential that you know how to recognise the sound.

The intensity of the alarm is usually indicated by the manufacturer. Most detectors incorporate an 85-decibel alarm which will be more than enough to wake up an entire home in the event of a fire.
