Most emergency lighting schemes fall into one of the following categories:

  • Non-maintained - The emergency light units only illuminate in the event of a mains failure.
  • Maintained - The emergency light units are illuminated at all times using the same lamps for both normal and emergency operation.
  • Sustained - The emergency light units are fitted with two lamps or two sets of lamps. One of which operates on mains 240V AC supply, the other which operates from the battery supply in the event of mains failure. It is basically a non-maintained system with the addition of mains lamps which should be illuminated whenever the premises are occupied.
