The XG-C406H Wired Smoke & Heat Detector is a robust, dual-function fire detection device designed to provide maximum coverage and early warning by combining photoelectric smoke sensing with heat detection at a fixed threshold of 57°C. It is especially effective in areas where smoke alone might not trigger an alarm, such as kitchens, garages, warehouses, and commercial environments. Supporting both 2-wire and 4-wire configurations, the XG-C406H ensures easy installation into new or existing fire alarm systems. It features a low standby current (≤50μA), contributing to energy-efficient, long-term operation, and activates with both a visual LED indicator and audible alarm for fast and clear emergency response. With EN54-7 and EN54-5 certifications and CE approval, the XG-C406H meets stringent international safety standards, making it a reliable and essential component for advanced fire protection systems.
