The Duracell MN21 is compatible with all batteries that bear one of these designations.Why does this small battery have 12 volts?The MN21 is not a single cell, but a battery pack. Inside, there are eight small 1.5-volt alkaline button cells, which are connected in series (8 x 1.5V = 12V) to achieve the high voltage required for radio transmitters.How long can this battery be stored?Thanks to Duracell Duralock Power Preserve technology, this battery can be stored for up to 5 years when stored correctly in a cool and dry place, without significant loss of capacity.How should this battery be disposed of?Batteries must not be disposed of with household waste. Please take the empty battery to the designated collection points in retail or municipal recycling centres to ensure environmentally friendly recycling.

This high-quality emergency luminaire from Beltrona was specially developed for discreet installation in suspended ceilings and ensures reliable and standard-compliant emergency lighting in the event of a power failure. As a self-contained single-battery luminaire with a long-life battery and automatic test function, it offers maximum flexibility during installation and low-maintenance operation. The luminaire combines an unobtrusive design with modern LED technology and optimised lenses for illuminating escape routes or anti-panic areas.Highlights at a glanceDiscreet recessed installation: Ideal for seamless and architecturally appealing installation in grid or plasterboard ceilings.Self-contained single-battery system: Integrated, long-life battery (e.g. LiFePO4) for an emergency lighting duration of 3 hours.Automatic test function: Performs regular self-tests and displays the status by means of an LED, which simplifies maintenance.Optimised illumination: Interchangeable lenses for requirement-based escape route or anti-panic lighting.Durable LED technology: High efficiency, long service life and minimal maintenance.Reliable illumination in an emergencyThis emergency luminaire is the ideal solution for regulation-compliant emergency lighting in a wide variety of buildings. The recessed ceiling installation is perfect for use in corridors, offices, retail premises, schools and hospitals. It ensures that escape and rescue routes are clearly visible in the event of an emergency and that panic in larger areas is avoided by means of sufficient illumination, without disturbing the overall architectural appearance.Advanced and efficient LED technologyThe heart of the luminaire is a modern LED module that ensures high luminous efficacy with minimal energy consumption. Compared to older fluorescent lamps, LED technology offers a significantly longer service life of up to 50,000 hours, higher switching resistance and immediate, full brightness in an emergency. This considerably reduces operating and maintenance costs over the entire lifetime of the building.Developed for easy installation and minimised maintenanceThe luminaire is designed for quick and error-free installation by a professional in standard ceiling cut-outs. As it is a single-battery luminaire, only a 230V mains connection is required. The automatic test function (autotest) independently checks the function of the luminaire and battery at regular intervals and indicates the status via a multi-coloured LED. This significantly reduces the manual testing effort and lowers operating costs. Features  ModelBeltrona LED emergency luminaire (recessed ceiling) General luminaire data ApplicationEscape route & anti-panic lighting Mounting typeRecessed ceiling Operating modeContinuous / standby mode Luminous flux (lumen)approx. 180 Light sourceLED (integrated) Installation diameter (mm)approx.

The anti-panic lighting uses a wide, rotationally symmetrical lens to evenly illuminate large, open spaces (e.g. foyers, conference rooms), making orientation easier and helping to prevent panic.What is the advantage of a single-battery luminaire with autotest?A single-battery luminaire does not require connection to a central emergency power supply and is therefore very flexible to install and ideal for retrofitting. The autotest function automates the prescribed function tests and reports faults directly on the luminaire, which greatly simplifies regular manual inspection.Can the luminaire be operated in continuous and standby mode?Yes, modern single-battery luminaires are generally designed for both operating modes and can often be set directly on the luminaire. In standby mode (BS), the emergency lighting is only activated in the event of a power failure. In continuous mode (DS), it illuminates permanently and can, for example, contribute to general orientation lighting.What advantage do modern batteries such as LiFePO4 offer?Modern lithium iron phosphate batteries (LiFePO4) offer a significantly longer service life of up to 8 years compared to older NiCd batteries, halving the maintenance intervals. They are also more environmentally friendly as they contain no toxic heavy metals.
