The Consilium DOS3 is a high-performance analogue addressable optical smoke detector designed for reliable fire detection in demanding environments, particularly within marine and industrial applications. It operates on the light-scattering principle, making it highly effective at detecting slow-burning, smoldering fires that produce visible smoke particles. The DOS3 features advanced algorithms to reduce false alarms caused by environmental factors like dust and humidity. Its low-profile design and clear LED alarm indicator make it a discreet yet effective component of any Salwico fire alarm system, such as the CS3000 or CS4000.
