What Is the Difference Between Maintained and Non-Maintained LED Exit Signs?

A maintained LED exit sign stays illuminated during normal operation and continues to operate during a mains failure using its emergency power source. A non-maintained LED exit sign remains off during normal conditions and illuminates when the normal power supply fails. The appropriate type depends on the building's use, the escape-route design and applicable requirements.

Where Are Maintained LED Exit Signs Commonly Used?

Maintained exit signs are often used in premises where exit signage needs to remain illuminated during normal occupancy, such as certain public buildings and entertainment venues. The correct choice depends on the specific building and its emergency lighting design.

Do Maintained and Non-Maintained LED Exit Signs Both Need Emergency Power?

Yes, both types need an appropriate emergency power arrangement if they are intended to operate during a mains failure. This may be provided by an integral battery or a central emergency power system, depending on the fitting and installation design.
