I agree but according to BS5266 a maintained fitting is to be illuminated at material times. Some manufacturers such as Fern Howard provide two rating plates for you to fit whether it be non maintained or maintained whilst Eterna still manufacturer them as separate entities. I have had technical arguments with both Channel and Ansell who fit maintained rating plates yet claim they can be connected for non maintained operation, the technical department at Channel refused any more correspondence with me knowing they are incorrect. If a fitting has a rating plate stating maintained then according to BS5266 that is how it should operate.
