Fire rated emergency mini down lighter........

[FFM]

Hi all,

I have a question....

Does anyone know of a fire rated emergency mini downlighter that has been specified for use within a metal web (posi joist) ceiling? Fire rating must be 60 or 90min due to joist depth.

I am struggling to find anything other than converting a fire rated standard mini down lighter, but am limited as the conversion pack needs to be installed through the cut out as zero access from above. The smallest (diameter wise) kit I can find is 42mm and discrete is the name of the game with this project. I would like stay clear of a remote battery system if at all possible......

Any ideas of products would be amazing!

Cheers,

FFM

Have you looked at Ansell

Hi UNG,

Yeah, I spoke with their tech services earlier this week and none of their emergency down lighters have a fire rating. Bit surprising really....

How about KSR lighting

This datasheet lists emergency options

Hi UNG,

Yeah, seen these but only tested against solid joists and not web joists! Their range is also too large (physically) for the project! It's a real pain.

I have a plan B, which is the conversion of standard mini downlighters (cut out 42mm, bezel 48mm) but am getting some grumbling re the standalone LED indicator that will also need to breach the barrier from the FO. The designer squawked when `I mentioned the discrete, twin spot units like the Lluma emlux.....

I have spoken with various fire companies and they dont have any suggestions either... I know that the new `google building in London is an all timber construction with web joists, so might also try to see what they did.

Grrrrr!
