When your running lighting with PIR`s ....its happy days, you have a nice permanent live supply to the pirs and em lighting.....good idea is to run 3 core throughout the installation...tapping off permanent live, switch live etc....as you go,

I see would it not be a struggle to have 2 sets of 3 core to terminate in the pirs so wire to pir then to key switch back to emergency light then to non emergency light and so on is this correct in what im thinking.thx

no think abaut it.....2 core off db L & N, into combined light switch and test switch.....3 core from light switch 1 perm live, one switched, one neutral.....now along this 3 core, you can install any number of lights, any number of pirs, and any number of em lights.

lol like the picture I want to install x2 pir sensors to activate lights as the corridor is long within these lights will also be an emergency light sorry if I did not explain very well.

As i have said you can install as many pirs or lights as you wish along the the 3 core cable....just follow L in, L out and N......

what about 2 pirs to turn on same set of lights lights will be grid lights with x2 emergency

Sorry the circuit diagram itself is fine, very clear, I was just amused by the name. Very childish!:35:

A good drawing drawn by a spark, I bet the OP who surely isn't one has now copied it on the back of a smoke packet ready for the mornings work, god help the customer.
