  Smoke detectors you should know.

  Smoke detectors are simple devices, easy to install, inexpensive, and most importantly, designed to save lives. Most domestic accidents are fire-related. Choosing the best one for your home can be complicated because so many models are on the market.

  What is a smoke detector?

  A smoke detector is a siren that detects smoke in the air and emits an audible signal to warn you of the danger of a fire in your home. Regarding detection methods, there are two types of ion and optical detectors. Both are sensitive to combustion fumes, although ionic fumes are more sensitive than others.

  When fire detectors are connected to an active visual or audible alarm center, they are called smoke detectors. Instead, a single device that is battery-powered and operates independently is called a smoke alarm. In this paper, we have chosen the term detector.

  What are the international regulations for smoke detectors?

  The international manufacturing quality standard for smoke detectors is ISO 7240-7. In the US, they are manufactured using UL268. The European Union manufactures smoke detectors by the European Committee for Standardization (CEN) manufacturing standard EN 54 Part 7.

  What is a third-party or independent laboratory certificate?

  All smoke and fire detection products must be approved by an independent laboratory (third party) to demonstrate the minimum safety and quality of the device as it is designed to save lives. Third-party certification ensures that manufacturers meet minimum manufacturing requirements.

  In certification, not only does the quality of the equipment need to be demonstrated, but the manufacturing company must have a management program to ensure that all manufactured products are of the same quality. In this sense, several laboratories are renowned and recognized worldwide.

  What are the basic principles of installing smoke detectors?

  It is common for smoke detectors to be installed in kitchens. However, it often backfires as it’s usually activated by cooking fumes, and you eventually remove it. It’s best to install it somewhere outside the kitchen, between it and the living room if possible, on the ceiling and centered so it does what it should.

  •   To give you a better idea of ​​where and how to install smoke detectors, we’ve created this list with some basic installation guidelines:
  •   If the ceiling temperature is above 37.8 degrees Celsius (ºC), choose a model approved for higher temperatures. Otherwise, it will burn from the heat.
  •   Avoid installing it in the kitchen. Smoke from cooking can trigger an alarm, causing false alarms.
  •   Do not install the detector where there is a strong vibration.
  •   Humidity will affect its operation; please do not install it in corners or places that are wet or prone to water leakage.
  •   It is recommended to install one smoke detector every 60 square meters.
  •   If the ceiling is high, more detectors should be installed. This is done to counteract the “smoke cone” effect.

  What maintenance do smoke detectors require?

  Fire detection systems require maintenance to ensure proper operation. Photodetectors require more attention than other detectors. Since they have a camera with two optics that capture changes in light, it must be kept clean at all times.

  It is essential to clean smoke detectors thoroughly as they can be damaged by dust, moisture, and dirt buildup. If this happens, an alarm may be triggered unnecessarily. On the other hand, you should check battery life. For this review, a test button is usually included to make it easier to read its status.

  What are the disadvantages of smoke detectors?

  There are a few downsides to smoke detectors. They are necessary equipment that can save your life. However, in models that are not very advanced or of poor quality, “false positives” can occur. Smoke from cooking, cigarette smoke, and even bathroom steam can trigger detection.

  This could be due to poor quality detectors, or it could be due to incorrect installation. Another inconvenience could be its installation, some models include all the necessary materials, but some don’t. The battery can also be an issue, especially if they don’t last long or require you to have regular checkups.

  Where should I install smoke detectors?

  The size of the house or room in which you will place the detector will determine the amount of equipment required. But beyond that, other factors must be considered. Only certain professionals can install specific models, and you must remove any nearby elements that might prevent them from functioning correctly.

  Here is a list of some tips on where and how smoke detectors should be installed:

  •   Certification. First, we’d like to point out that you should only buy approved smoke detectors.
  •   Electrician. A professional electrician must install alarm systems connected to the grid.
  •   The best place to install it is in the center of the ceiling. The reason is the lack of air circulation in the corners.
  •   Care must be taken when positioning the detector. Any decorations should allow at least 30 centimeters (cm) of separation.
  •   Avoid false alarms: Having smoke detectors in the kitchen is inconvenient. Instead, place temperature detectors to detect sudden rises and warn of fire risks.
  •   A detector should be installed in every room: if the bedroom door remains closed at night. This is also important if you are a smoker.
  •   Pay attention to the location: they should not be near appliances, air conditioners, or hot air outlets.

  What should I look for in a smoke detector?

  Depending on the quality of the smoke detector, some products will give you better features and some additional features. For example, if an alarm is falsely triggered, a pause button is often included to stop the alarm. It’s also essential to have a test system to see battery levels and check operation.

  Among the accessories and features you should be looking for in a smoke detector, the most common are:

  •   Remote control mute button. Silence the most annoying alarms.
  •   Security lights provide illumination during notices.
  •   Send alerts to a central monitoring station as part of a security alert system.
  •   The intercommunication between devices is realized through wired or wireless systems to connect all devices.
  •   Mobile app to receive alerts on your phone.

  purchase criteria

  There are many brands and models of smoke detectors on the market. In general, choosing the one that best suits your home’s needs is difficult.

  function

  Most smoke detectors on the market are used to detect various types of fires. The teams reacted to the smoke-forming particles and sounded the alarm. As a general rule, they usually only see smoke. Some people may respond to boiling water or steam from a bathtub, but that indicates poor product quality.

  Other devices have additional capabilities, such as detecting gases such as carbon dioxide (CO2). These devices are more advanced and can detect dangerous gas leaks. Some models include LED lights turned on by motion detectors for lighting at night.

  Battery

  These devices typically run on 1.5 V AA or AAA batteries and are low-power so that they can work for years without battery replacement. Some of the more advanced models use separate batteries, and these models can work uninterrupted for up to 10 years.

  The problem with a smoke detector with a separate battery is that it cannot be charged, so once it reaches ten years of life, it shuts off, and you will have to replace the device. Most devices will notify you at least 30 days before shutting down.

  connectivity

  Ideally, choose a smoke detector that can be connected to other devices. Some models are interconnected, and others can be synchronized with other sensors (gas or particles) so that when one is activated, all units in your home will sound an alarm.

  However, you will find that some models must be connected to a power or phone line because they notify emergency centers. These models are more expensive and must be installed by a professional.

  mute function

  It would help if you had a mute or snooze button to silence an annoying or erroneous smoke alarm. These buttons allow you to stop the signal without completely disabling the device. This option is important because it avoids the problem of not remembering to plug it in and not working when needed.

  Today, you’ll find this option in all (or the vast majority) of smoke detectors on the market, along with other options like recalibrating the sensor or checking battery status. These buttons are usually large and can be used from the ground, such as with a broom.

  type

  Smoke detectors can be photoelectric or ionizing. The first has a lens that detects changes in smoke production in the light, and they are the most commonly used and cheapest models. They exist in many homes, require no installation, require little maintenance, and you can get them for less than $20.

  Ionization is sensitive to moisture and small particles suspended in the environment during a fire. They are usually fast and cheap. Hybrid models are recommended as they can detect carbon dioxide and gases, providing more comprehensive protection for your home.

  Install

  One aspect that users often question is how complicated it is to install a smoke detection system in their home. Although a lot depends on the type of detector, installation is usually always straightforward. You don’t have to screw the sensor to the ceiling; just stick it with some kind of tape.

  You also don’t have to configure anything. You just need to turn it on and check that it’s working (you can do this by burning a piece of paper in a safe place, like a bathtub or sink). If you opt for a more complex system, you need to hire a professional electrician to install it.

  Sensitivity

  This is a complicating factor. An overly sensitive detector will trigger any smoke. This possibility can be a problem because it can be triggered by the smoke from cooking, cigarettes, or even steam in the bathroom. These false positives will tire you out of the detector and eventually turn it off and put it away.

  The best smoke detectors, while they are susceptible and detect smoke very quickly, do nothing. If you’re not very clear on this factor, look at the user reviews, and if they complain that it doesn’t activate, don’t buy it, and vice versa. Try to choose a model that works well.

  alarm

  The alarm is one of the essential elements of the detector. Along with the detection system, the notice will be decisive as it will be the only way you will know if there is a fire in your home. Discard any models with a weak or inaudible signal, as it is essential to understand what is being played.

  The manufacturer usually indicates the intensity of the alarm. Most detectors include an 85-decibel alarm, enough to wake up the entire house in the event of a fire.

  Should there be a smoke detector in every room?
