Knowing the Types of Smoke Detector

!±8± Knowing the Types of Smoke Detector

Providing the best smoke detector is an inevitable need in your daily life especially if you put the great concern to the matter of fresh and clean air. In this case, there are many different types of the equipment above you should know, thus you can make sure to choose the right suitable product for your daily needs. What should you take as the alternative? In this case, you need to read the following explanation to let you deal with the matter above.

Firstly, you need to know about the definition of smoke detectors and its function. It is the device to detect the smoke and give the warning for the users when it starts to detect the existence of smoke in a room. The size is about a hand and can be fitted to the ceiling. Further, this one will detect the fires soon and give the time for family to leave the house in safety. Commonly, there are three major types of smoke detectors: the ionization, optical and the combined type. The ionization is claimed to be the cheapest product of all. This one is very sensitive in detecting the small smoke particles from chip pans and other sources.

What about the optical detector? It is more expensive and more effective to detect the larger particles from slow burning fires. The last type is the most preferable type for many people. It combines the good capability of detecting the fires from flaming and slow burning fires. It is important to know that the three types above have the similar looks and they are divided into two major types based on the operation. You can choose the battery operated one or the product which requires electricity in its operation. Buying this kind of equipment has been a part of daily need in this modern life.

Smoke detectors are one of the most important devices when it comes to fire safety in your home. They are the first thing that will alert you to a fire or smoke in your home, they can be the difference between life in death in a fire because every second counts and it is smoke detectors that can give you the early warning sign. No home should ever be without several smoke alarms,

There are two main types of smoke alarms available on the market today, namely ionization smoke detectors and photoelectric smoke detectors.

Ionization smoke alarms use a very small quantity of radioactive material to ionize air in an ionization chamber. This chamber becomes conductive allowing current to flow between two charged electrodes. When products of combustion enter the chamber such as smoke particles, the conductivity of the air in the chamber is lowered. When the conductivity of the air is lowered to a predetermined level, the alarm will go off.

Photoelectric smoke alarms consist of an LED (light emitting diode) and a light sensitive sensor in a sensing chamber. If products of combustion, like smoke particles are found in the chamber they will cause the light to scatter and stop the light from reaching the sensor, this in turn causes the alarm to sound.

As the two types operate on two different sets of principles, they may respond differently to various conditions

Ionization alarms are better suited for rooms that contain highly combustible items that will create flaming fires. These items would include flammable liquids or newspapers. Photoelectric devices would be better suited for bedrooms, living rooms and kitchens, as these rooms often contain large pieces of furniture, such as mattresses, armchairs or sofas which would burn more slowly and create smoldering smoke rather than hot flames.

Each of the types of alarms have been tested and certified by fire safety authorities to be used within the home and as each react slightly better to different types of fire it is probably best to have a selection of both types located around your home.
