Hi
Would appreciatte some advise and pointers on the following.
Im an industrial sparks who has been tasked with fitting some emergency lighting in a factory im responsible for. The emergency lights that are required first are exit lights that go above the fire exit doors. We have been provided with these units (they are Thorn E3M bulkheads) which are a maintained self contained fitting and it is desired that these are used.
I have ordered a copy of BS5266 as it looks kind of essential im familiar with it as my experience of emergency lighting circuits is limited. I would therefore appreciatte some comments on the following questions
1, There are several lighting circuits throughout the factory (which has different workshops), the emergency lights in each area will be powered from the lighting circuit for that particular workshop.....this seems to be how it should be done. Im not familiar with the circuit design however.....the Bulkhead fittings have 4 terminals, E,N,L1 and L. L1 and L have a removable link already fitted between them.......what is the purpose of this and how should the circuit be wired for these maintained self contained fittings? Where do the two line conductors 'come from'?
2, Should the emergency lights remain on even when the normal lights are shut off (at night for example)? If so then they will have to be wired into the normal lighting circuit 'before' the functional switch??
3, Does each fitting need its own test switch or would 1 test switch be ok for all that workshops fittings?
Regards
