The fitting includes four interchangeable legend panels (up arrow, down arrow, left arrow, right arrow) allowing the directional arrow to be changed on site without replacing the entire unit. A lithium battery provides backup power to keep the exit sign illuminated during mains failure.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial buildings, offices, retail spaces and hospitality venues where emergency exit signage is required under UK building regulations, the Duceri hangs from a ceiling-mounted backplate with drop cables concealing the electrical connection. The maintained mode means the sign remains illuminated at all times during normal mains operation, not just during power cuts, making it visible day and night. The IP20 rating suits indoor dry locations.\u003c\/p\u003e\n\u003cp\u003eThe 3W LED produces clear, high-contrast green and white graphics visible at typical corridor and room distances. The white polycarbonate housing is impact-resistant and the legend panels clip into the front face, allowing the arrow direction to be rotated or changed during installation or later if the building layout changes. The lithium battery backup provides longer service life and more charge cycles than older nickel-cadmium alternatives.\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\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e1.13\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e11.3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e335\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003ctd\u003e245\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\u003e350\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e470\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e265\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_D330AWH_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_D330AWHManual.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between maintained and non-maintained mode?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMaintained mode keeps the exit sign illuminated at all times when connected to mains power, switching to battery backup during power failure.
