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.
The ceiling mountable Calabor 8W recessed emergency lighting bulkhead light slave unit, with a thin front trim plate and prismatic diffuser, provides a low-profile and stylish finish suitable for indoor use.
The Arc 8W Slave Unit is powered from a central bank of batteries located within the building to ensure escape routes are illuminated during a power failure. Featuring an IP65 rating, the AR8 is suitable for indoor and outdoor use.
Using slave functionality, allowing it to illuminate after a mains power failure via a separate central battery system located within the premises, the Pico is available with four different directional arrow legends to choose from.
Available in a range of voltages, the Calabor single-sided 8W fire exit sign slave unit obtains its emergency back-up power supply from a separate central battery system located within the building.
The Calabor double sided 8W fire exit sign slave units are powered by a bank of larger batteries centrally located within a building. Available with a choice of 3 directional arrow legends.
The Arrian slave emergency light is designed to be low-profile, with an aluminium body that seemlessly blends into modern office environments. Available for 24V, 50V, 110V, and 230V input and provides over 770 emergency lumen output.
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.

Self-extinguishing polycarbonate body and diffuser
IP55 rating for use outdoors or in light industrial environments
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.
