The detector uses optical smoke sensing and thermistor-based heat sensing inside a 150mm diameter white plastic housing with a built-in mounting base.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial fire alarm installations where flexibility in detection mode is required without changing hardware, the MagDuo allows installers to configure sensitivity and response type via DIP switches on the device. The 2-wire connection simplifies installation compared to 4-wire detectors, running power and alarm signal on the same pair. The built-in End of Line function eliminates the need for separate EOL resistors in addressable or conventional fire alarm panels that support this feature.\u003c\/p\u003e\n\u003cp\u003eThe detector self-calibrates every six hours to compensate for dust accumulation and environmental drift, extending service intervals between manual cleaning. Continuous dust contamination monitoring triggers a fault signal when the optical chamber reaches a threshold where cleaning is necessary, preventing nuisance alarms from gradual sensor degradation. The 150mm base footprint fits standard UK fire detector mounting boxes and the 80mm overall height allows installation in locations with limited ceiling void clearance.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Net Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.25\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.25\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e150\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003ctd\u003e150\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Height (mm)\u003c\/td\u003e\n\u003ctd\u003e80\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e150\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e150\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e80\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_MAGDUOSHD_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/manual_MAGDUOSHD.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the seven detection modes?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe MagDuo offers standalone smoke detection, standalone heat detection, combined smoke and heat detection requiring both sensors to trigger, and variations on sensitivity thresholds for each mode.
