Like Teletrix, the oldtimers rough sketch is clearer to me, sorry Dean!!! But then schematic has always been better for me... lol!!!

 

[Dean182]

No Probs. Just to add to oldtimers sketch, the key switch for the e lights shouldn't be wired in parallel with the photocell and override switch. As this way all its doing is providing another way of energizing the coil, as opposed to providing a permanent feed to charge the e light battery

Thanks for the help/diagrams ive done the attached drawing hope its right!

 

[oldtimer]

Remember location location and if all these devices wire back to a central area then thats where the junction box kicks in.
And yes both drawings are handy

right finally wired this today and all worked as it should. Another quick question tho.
I've got to connect another set of staircase lights to the contactor do i just link terminals 1 and 3 and take my feed to the lights from 4 or can i feed terminal 3 from a seperate mcb and take my feed to the lights from 4

You can take a new supply to a spare pole on the contactor, If it's not on the same phase, make sure it's marked as being 415v.
