One of the key features of SOS Connect is its photoelectric system, which plays a crucial role in detecting hazards. When smoke, generated by the early stages of a fire, enters the detector’s darkroom, the infrared light scatters on the smoke’s surface. This scattered light is then captured by a photoelectric diode, generating a photoelectric signal current. The identification circuit processes this signal, and upon detection of a potential threat, the alarm circuit is activated, promptly alerting users to the danger. With its reliable and efficient design, SOS Connect provides peace of mind and an added layer of safety for both residential and commercial environments.
