This 230V smoke detector with 9V backup battery from the Ei Electronics / Hemmink brand is an optical smoke detector.
With an optical smoke detector, an infrared light beam is sent to a receiving cell. When smoke enters the path of the light beam, the receiving cell notices that nothing is coming in. The smoke detector then sounds an alarm.
