A smoke detector is a critical fire safety device designed to detect the presence of smoke in the air and provide early warning of a potential fire. By identifying smoke particles at the earliest stage, it helps prevent fire spread and allows occupants to evacuate quickly and safely.
Smoke detectors typically use either ionization or photoelectric sensors to detect smoke. Once smoke is identified, the device triggers a loud alarm sound to alert people in the building immediately. Some advanced models can also be connected to centralized fire alarm systems for wider emergency response.
