The XG-C405H Wired Smoke & Heat Detector is a high-performance dual-sensing device crafted to deliver enhanced fire protection by combining photoelectric smoke detection with fixed-temperature heat detection at 57°C. Designed to operate reliably in environments where smoke alone might not indicate a fire — such as kitchens, garages, warehouses, and industrial areas — the XG-C405H provides broad, highly effective coverage. It supports both 2-wire and 4-wire configurations, ensuring easy integration into a wide range of DC 9V–35V fire alarm systems. The device offers low standby power consumption (≤80μA), a visible red LED indicator, and rapid alarm activation during fire conditions. Compliant with EN54-7:2008 and EN54-5:2008 standards, and CE certified, the XG-C405H guarantees trusted performance and high reliability for life safety applications. Constructed with durable ABS housing and designed for harsh or dust-prone environments, it is an essential component for modern, comprehensive fire protection systems.
