What are slave emergency 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?

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.
