The XGF-C403 Wired Smoke Detector is a TÜV-certified, EN54-7 compliant photoelectric smoke detector, purpose-built for professional-grade fire alarm systems in residential, commercial, and industrial environments. Engineered for fast and reliable smoke detection, it uses optical sensing to accurately detect smoke particles at a sensitivity range of 0.08–0.16 dB/m. It operates on DC 9V–35V with an optional version for DC 40V–60V, providing maximum flexibility across project types. Supporting both 2-wire and 4-wire configurations, the XGF-C403 offers easy integration, while its low power draw (≤80μA standby) ensures energy-efficient performance. A bright red LED indicator gives immediate visual feedback during alarms. Constructed from flame-retardant ABS, the XGF-C403 is ideal for installations in apartments, offices, hospitals, schools, factories, and retail buildings where precision, safety, and reliability are essential.
