Local Battery Emergency Lighting Suitability

me1899
Hi All, hope all well


Got a query on em lighting.


Got a 16m high new build storage racking warehouse where I am proposing central battery emergency lighting.


2 units, fire rated feeds to busbars (the busbar system and associated plug in lights being certified as acceptable to use internal conductors for the emergency feeds as opposed to separate cabling to every luminaire).


Someone is now suggesting to go local batteries - 124 of them which I think is bonkers mounted at 16.5m.


Is there a reg to throw back at them in addition to the obvious comments on maintenance, effect of elevated ambient temperature up there (lots of rooflights present)?

    It's purely cost mate, we are working for the builder who is providing the warehouse for the tenant - not quite shell as they will be installing the racking aisles.


    They have privately admitted that their costs are wrong and are starting to panic.


    Another one of their bright cost saving (rejected) ideas was asking to omit containment that was shown at the perimeter and sling cables through the structure of the warehouse - all the way round the 100m x 140m building.
