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)?

    Well the busbar is actually reasonable cost wise - it is one of those Zumtobel Tecton jobbies that is quick as anything to install and the fittings just clip on.


    The manufacturer's quote had 32 quid for a 4 metre run - amount of cable to run to each emergency fitting would have been over 2,000m without the busbar.


    And the internal conductors can be used as the emergency feeds so only  cabling to the ends of the busbars - saves a lot of material.


    The central battery units are coming out about 8k for 2 of them.
