The sign uses SMD 2835 LED chips emitting 5500K daylight-white light, achieving a 25m viewing distance in clear conditions. Maintained operation means the sign remains illuminated during normal mains power and switches to battery backup during power failure, providing 3 hours of emergency runtime from a 3.6V 1500mAh Ni-Cd battery.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial, industrial and public building installation where emergency egress signage is required by building regulations, the Duceri mounts to walls above doorways or at changes of direction in escape routes. The up arrow legend directs occupants towards upper floors, staircases or ceiling-level exits. The steel housing withstands impacts better than plastic emergency signs and the black finish integrates into industrial and modern commercial interiors without the high-visibility green or white housings typical of budget emergency lighting.\u003c\/p\u003e\n\u003cp\u003eThe unit includes charge and discharge protection circuitry to prevent battery degradation and a green LED indicator on the front face confirms the battery is charging correctly when mains power is present. The sign complies with BS EN 60598-2-22 standards for emergency lighting performance and includes wall-mounting brackets for vertical surface installation. The 1.3kg weight requires secure fixing into masonry or metal stud partitions rather than plasterboard alone.\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\u003e1.31\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e1.495\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e9.42\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e200\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003ctd\u003e90\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Height (mm)\u003c\/td\u003e\n\u003ctd\u003e45\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e420\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e425\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e260\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_EMLED3WMEXBOXBKU_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does maintained operation mean?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMaintained operation means the sign stays lit continuously when mains power is available, and switches to battery backup during power failure.
