Central Battery Slave Emergency Lights & Signs
Emergency lighting slave lights and signs obtain their emergency power supply from a separate central bank of batteries located within the premises. The central battery system makes maintenance and testing easier, and fittings are available in 24V, 50V, and 110V AC/DC.
Recessed LED Emergency Slave Downlight - Elled
The Elled is a small LED emergency light designed to be powered by a central battery system, available in a choice of 110V or 230V and compliant with both 850°C glow-wire and needle-flame tests.
- Open area and corridor models available
- Small, recessed body blends into any interior design
- High quality LED with a lifespan of 50,000+ hours

Voltage for Slave Luminaires
Our slave emergency lighting units, also called slave luminaires are available as 24v, 50V and 110 units. They are switchable AC/DC lights.What are slave emergency lights?
Rather than each emergency light having its own battery, slave emergency lights are powered by a central battery bank in the event of a mains power failure. The central battery is also responsible for monitoring the mains power supply for failure, so the fittings themselves are not connected to the standard lighting circuit as self-contained emergency lights would be. Slave fittings can be installed for maintained operation, again determined at the central backup battery, not the fitting. Slave fittings are available for a wide range of voltages.Where are centrally-powered emergency lights used?
Centrally powered slave emergency lighting systems are typically used in larger premises due to the considerably simplified testing and maintenance offered in comparison to self-contained emergency lighting fittings. Central battery banks are also usid in buildings where environmental factors would adversely affect the performance of self-contained backup batteries, such as temperature fluctuations, which would reduce battery life. Due to backup batteries in self-contained fittings typically having the shortest lifespan of all components, slave systems also provide benefits in hazardous or sensitive areas where maintenance engineers may require special permission or training to enter.Advantages & Disadvantages
