Description of Maintained & Non-Maintained: Non-maintained emergency lighting is designed to turn on in the event of a power failure. It is linked into the buildings lighting circuitry and reacts to a power failure ensuring emergency exit routes remain illuminated. This type of emergency lighting is mostly found in the workplace, such as offices and factories, where people are familiar with the escape routes. Maintained lighting is designed to be lit continuously and will continue to work even in the event of a power failure. This allows the unit to double as a standard light fitting but still supply the necessary backup in the event of a power outage. This type of emergency lighting is suitable for public places such as theaters, shopping malls and cinemas.
