Smoke detectors are one of the most important features of any home. This is because the smoke detectors are often the difference between a person surviving or dying in a house fire. Approximately 2000 to 3000 people die in fires every year in the United States. Many of the people who died in fires do so because the building had no smoke detectors, or the smoke detectors were not working at the time of the fires.
Because smoke detectors are so important when it comes to saving lives and home electrical safety, it is a very good idea to understand how they work. This article will provide a brief overview of how smoke detectors work.
Ionization Smoke Detectors
Ionization smoke detectors one of the two main types of smoke detectors. These smoke detectors are set up so that a tiny amount of radioactive material rests between two metal plates. This radioactive material is americium-241. A constant small electrical charge exists between the two metal plates. The smoke alarm is triggered when smoke floats up into the chamber and disturbs the electrical charge between the two plates. Typically, the alarm noise will be extremely loud and will awake anyone in the home or other building who may be sleeping or otherwise unaware of the fact that a fire is burning in the building.
Photoelectric Smoke Detectors
Photoelectric smoke detectors are the other primary type of smoke detector. These smoke detectors work in a different way to ionization smoke detectors. The way that photoelectric smoke detectors work is by sending a tiny beam of light from a diode to a sensor chamber. When smoke enters the chamber, it disrupts this light beam and triggers the alarm. Again, with this type of alarm, the noise is very loud, and it should easily be able to awake anyone who is sleeping in the home or building, or who may otherwise not be aware that there is a fire in the building.
The Importance of Having Smoke Detectors
