Fire detection refers to the process of identifying the presence of fire or smoke in an environment. This is typically achieved through various devices, such as smoke detectors and heat sensors, which monitor changes in temperature or the presence of smoke particles. When a fire is detected, these devices can trigger alarms to alert occupants and initiate safety protocols. Effective fire detection systems are crucial for protecting lives and property. They are commonly used in residential buildings, commercial spaces, and industrial facilities. Regular maintenance and testing of these systems ensure they function properly, providing early warning in case of a fire emergency.
