The sign operates in maintained mode, meaning the LED illumination stays on continuously during normal mains power and switches to battery backup during power failure. The 3W SMT 2835 LED array produces 5500K daylight white light visible from 25 metres, meeting BS EN 60598-2-22 emergency lighting standards.\u003c\/p\u003e\n\u003cp\u003eDesigned for surface mounting on walls in corridors, stairwells and exit routes where vertical direction signage is required, the Duceri guides building occupants towards stairs, lifts or upper-level exits during both normal operation and emergency evacuation. The chrome finish suits commercial, retail, hospitality and industrial environments where a functional metallic aesthetic is preferred over painted white boxes. The sign requires connection to a permanent 230V mains supply and is wired into the building's emergency lighting circuit.\u003c\/p\u003e\n\u003cp\u003eThe integrated LiFePO4 lithium battery (model D001) provides 3 hours of emergency illumination once mains power fails, with built-in charge and discharge protection preventing over-discharge damage and extending battery service life. A green LED indicator on the face confirms that the battery is charging correctly during mains operation. The steel housing is wall-mounted using fixings through holes in the back plate, with cable entry via a rear knockout. The unit weighs 1.2kg net, giving it sufficient presence to resist accidental knocks once installed.\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\u003e1.2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e1.438\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e8.63\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e402\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Height (mm)\u003c\/td\u003e\n\u003ctd\u003e71\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_D120UCH_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_D120Manual.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does maintained mode mean?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMaintained mode means the LED stays illuminated continuously during normal mains power, acting as both a visible sign and emergency backup.
