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)?

    Hi OMS


    The warehouse is just chock a block with racking. They basically almost reach the roof. About 30 aisles 70m long and 1.75 wide (for those vna type forktrucks) so perimeter would be difficult I think. 


    Lux targets are 1 lux because of being narrow aisles and multiple defined escape routes. 


    Funnily enough there are no sprinklers, as the fire engineer has justified omission in their report. 


    In fact he said manual call points were all that was required initially. 


    ​We are proposing Vesda though.
