The S6-CSD-250 is a conventional optical smoke detector that uses infrared light scattering to detect different types of smoke, including very fine particles. Its specially designed chamber helps with smoke particle detection while also reducing interference from dust, insects, and false environmental light. The product literature also highlights remote indicator output, compatibility with SENS conventional panels, SMD technology, low power consumption, impact-resistant plastic construction, and a red LED status indicator with a 360-degree visibility angle. The manual further includes installation guidance, testing steps, remote indicator wiring, and a conventional system zone diagram.
