Füstdetektáló
Füstdetektáló, often translated as smoke detector, is a device that detects the presence of smoke, typically as an indicator of fire. Most smoke detectors work by using either photoelectric or ionization technology, or a combination of both. Photoelectric smoke detectors use a light beam and a sensor. In a clear chamber, the light beam does not reach the sensor. When smoke enters the chamber, it scatters the light beam, causing it to hit the sensor and trigger the alarm. Ionization smoke detectors use a small amount of radioactive material to ionize the air in a small chamber, creating a continuous electric current between two electrodes. When smoke particles enter the chamber, they disrupt this current, and the alarm is triggered. Combination detectors offer enhanced detection capabilities by utilizing both technologies. Smoke detectors are crucial safety devices in homes and buildings, providing early warning of fires, which can significantly reduce property damage and save lives. They are typically powered by batteries or directly wired into the building's electrical system. Regular testing and maintenance, including battery replacement and cleaning, are essential to ensure their proper functioning.
