Fire detection refers to the process of identifying the presence of fire or smoke in an environment. This is typically achieved using various types of sensors, such as smoke detectors and heat detectors, which monitor changes in air quality or temperature. When a fire is detected, these systems can trigger alarms to alert occupants and initiate safety protocols. Modern fire detection systems can be integrated with fire alarm systems and sprinkler systems to enhance safety. They are commonly used in residential, commercial, and industrial settings to protect lives and property from the dangers of fire. Regular maintenance and testing of these systems are essential for effective operation.
