I am currently doing a 3 hour duration test in Selfridges for the em lighting. When I turn off the mcbs the emergency lighting does not activate. I have asked if this is to do with the central battery system but the staff will not let me and my colleague touch it. Just wondering if anyone has had a similar situation and how they got around it.......
 
Have you been able to inspect one of the fittings as slave luminaries for central systems will contain no batteries nor will they have led charge indication or have you confirmed it is a central battery system.

can you give us some more i formation about the emergency lighting installation?
If it's a central battery system then you don't test it by running the lights for 3hours the same way you would self contained units.

However the emergency lighting, if non-maintained, should still come on with a loss of the supply to the normal lighting in the area.

question, do you know what you are doing !
 
Ok since you were rude I will be too. **** you. I know exactly what I'm doing. **** off if you're not going to help

Unfortunately we only have your opening post to go by, which suggests that you are testing a central battery system by operating the emergency lighting for 3 hours.
Since you know exactly what you are doing you are obviously aware that this is completely the wrong way of testing a central battery system.

Fitted a lot of this sort of light recently, with all tests reporting back through central Dali controller(s).

It’s getting to the point where full LED replacement is cheaper than spending time on testing and possibly replacing parts.
