The sign runs on mains power during normal operation and switches to an internal 3.6V 1500mAh Ni-Cd battery backup when mains power fails, providing 3 hours of illuminated exit guidance at 5500K daylight white colour temperature.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial buildings, offices, retail premises, hotels and public spaces where Building Regulations Part B requires illuminated exit signage, the Duceri box can be operated in maintained mode (always lit) or non-maintained mode (lit only during power failure). The self-test function automatically checks the battery charge level and LED function at programmed intervals, logging faults via a green LED indicator on the front panel. This reduces manual testing frequency and simplifies compliance with BS EN 62034 emergency lighting maintenance requirements.\u003c\/p\u003e\n\u003cp\u003eThe left-pointing legend arrow directs occupants towards the nearest exit on the left-hand side of the sign, with a viewing distance of up to 25 metres in clear conditions. The white powder-coated steel housing measures 390 x 190 x 60mm and weighs 1.3kg once fitted, providing impact resistance suitable for wall mounting above doorways and corridor junctions. The SMD 2835 LED lamp delivers consistent output across the 3-hour discharge cycle, with charge and discharge protection circuitry preventing battery damage from overcharge or deep discharge.\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\u003e1.32\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e1.57\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\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\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_EMSTLED3WMEXBOXL_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_EMSTLED3WMEXBOX.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the self-test function do?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe self-test circuitry automatically checks the battery charge level and LED function at programmed intervals.
