An optical smoke detector is a device that detects the presence of smoke in an area. It is often used in fire alarm systems. Optical smoke detectors are more sensitive to the bigger smoke particles produced by smoldering fires, making them ideal for early detection. They are commonly utilized in residential and commercial buildings to provide accurate fire detection and prompt evacuation and response in the event of an emergency.
