Thank you.
I notice that you have edited an earlier post regarding master switching.
I did indicate in my post that permenant feeds would have to be separate.

would just be 3 hour type internally self maintained with a permanent feed, the permanent feed going through the key test switches and need to test the lights weekly as is a nursery along with the fire alarm, and once a year fully discharged, timed to check 3 hour duration then left to fully charge again from permanent feed (always on live) the units would need changing every 5 years or so in line with the service life of the internal batteries....the exterior lights would be the D type flourescent bulkhead fittings and the interior ones I would recommend the 2 tube 8ft type, as recessed 3ft x 4 tube difuser units only have one of the tubes maintained and it is only a dim glow......
If it was a bigger building I would say that there should be a lighting inverter and a DALI controller for the whole lighting system but on this one I would recommend 3 maintained lights in each small room and 6 in each large room in addition to all the above door fire exit lights inside and out being self maintained ones, and taking into consideration the gathering point designated outside on the fire plan and any lighting on inside stairs and outside steps....

Who is designing this? What is their qualification for doing so? Will it be fully certificated? Will there be a log book? Will proper training be given to the responsible person? Will testing procedures and schedules be put in place? Will the installed system comply with BS5266?

If there is a fire and casualties, and the EL system is not up to scratch, there could be some serious fallout. If you fitted the system just based on someone else's say-so then you could be in the firing line at the Coroner's court. Emergency lighting needs to be properly designed and signed off - for insurance purposes too.

This place will be full of kids, do it right or don`t bother get someone in who can. I have done a few schools and nurserys over the years and most of the work is state funded and all the paperwork you provide is sent off to be inspected before the funds are released. Just think if it all goes wrong you need to know it will give them the best chance of escape. Not a job to wing and a prayer.

The BS states that maintained lighting only has to be on during material times.

You need to get a hold of the IEE eletricians guide to emergency lighting isbn 987-0-86341-551-7 you can order thriogh the website www.------.org/publishing/books/wir-reg
this will give you all the info you need but generally, at exits you need maintained exit signs with the apprirate legends, escape route illumination and escape route legends illuminated in some cases, but the guide is really a must as the subject is quite involved and design requires carefull thought
