Modern fire detection and suppression systems use advanced technologies to detect fire at an early stage, identify its location, provide warnings, and control or extinguish the fire rapidly. These technologies improve life safety, reduce property loss, and enable faster emergency response. Fire detection systems commonly use smoke detectors, heat detectors, flame detectors and multi-sensor detectors. Smoke detectors identify smoke particles produced during combustion. Photoelectric smoke detectors use light scattering to detect smoke and are particularly effective for smouldering fires, while ionization detectors respond rapidly to flaming fires. Heat detectors operate when the surrounding temperature reaches a predetermined level or when there is a rapid rise in temperature. Flame detectors detect ultraviolet (UV), infrared (IR), or a combination of _________ __________ _______ __________ ______ ___ ________ _______ ___ __________ ______ ____.
