A common question from customers buying emergency lighting is: What is the difference between maintained and non-maintained emergency lighting? New commercial or public buildings have emergency lighting installed as standard, but if you are looking to install or renew a system this issue may need clarifying.
Luckily the answer is really quite simple.
Non-maintained emergency lighting is designed to turn on in the event of a power failure. It is linked into the building’s 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 theatres, shopping malls and cinemas.
Emergency exit signs can also be lit to act as an emergency light. Again they can be maintained or non-maintained, with non-maintained signs reserved for areas where occupants are familiar with the layout of the escape routes.
