Hi All, hope someone can help me out. I am looking at a job just now regading emergency lighting but not sure how the land lies with the regs etc.
Currently in is 240v 4ft fluroscents switched on / off as per normal lighting and incorporated into these are 110v(battery bank) 15w pigmy lamps (always on so maintained).
The fittings are currently 25yrs old, diffusers ripped to pieces and shocking light output nevermind the T8 lamps, starters etc so the plan is to install 2 x 28w T5 HF fittings incorporating a 110v slave electronic ballast however i see a few problems but have answers i think!
I have already worked out the load factors etc in regards to the 110v and all is fine so here goes
1. When lights in the stairwell are switched off the pigmy stays on, if i replace with the intended fittings as mentioned above and the lights are switched off (its a college and kids will be kids) then there will be no lighting at all in the stairwell unless there is a power cut.
I was proposing to change the current light switches to key switches so only staff can turn them on/off, I also need to take a permanet feed to the new lightfitting to hold off the 110v(battery), so in a way I will have changed these fittings from maintained to non maintained which differs from the original install, so is this one for the fire officer, building control or changes made to the Fire Risk assessment? thing is the lux output currently is 1 lux at floor level, these fittings will be kicking out 80lux at floor level!
Your views will be of great value.
Thanks
