Tulekahjuandureid, more commonly known as fire detectors or smoke alarms, are essential safety devices designed to sense the presence of smoke, heat, or flames, and alert occupants of a potential fire. These devices play a critical role in early warning systems, providing occupants with precious time to evacuate a building before a fire escalates.

There are several types of fire detectors, each functioning on different principles. Photoelectric smoke detectors work by emitting a beam of light into a chamber. When smoke particles enter the chamber, they scatter the light, triggering the alarm. Ionization smoke detectors, on the other hand, contain a small amount of radioactive material that ionizes the air, creating a current. When smoke particles enter, they disrupt this current, setting off the alarm. Heat detectors respond to a rapid rise in temperature or a predetermined high temperature. Flame detectors are designed to sense the infrared or ultraviolet radiation emitted by flames.

Modern fire detectors often combine multiple sensing technologies to improve accuracy and reduce false alarms. They are typically powered by batteries or connected to the building's electrical system. Many are interconnected, meaning if one alarm detects a fire, all connected alarms will sound, ensuring a more comprehensive warning. Regular testing and maintenance, including battery replacement, are crucial to ensure their continued effectiveness. Fire detectors are mandated by building codes in many jurisdictions and are a vital component of fire safety plans for homes, businesses, and public spaces.
