I hope I can explain this ok... I have a property in Turkey (same as uk voltage) it has a couple of outside lights but I would like to link these to a couple OF PIRs for security reasons. The diagram below hopefully helps.
As you can see I have internal light switches that operate some outside lights but want to reposition these and have them activated by PIRS.
Can someone advise on what type of PIRs I require and how they are wired. I assume it is just basic wiring, which I would be ok with. I am presumong I go from the internal light switch to the PIR and to the light as far as wiring is concerned.
Where would be a good source of PIRs in the UK as I would need to take them over with me.also what type of cable should I use.
thanks

Ok first thing , im from New Zealand and NOT in anyway up to speed on the current regs in your Country , but i willl try and help best i can.

Ok assuming the Feed comes to the switch first ( if this is NOT the case then this maynot be correct )

The PIR needs a phase in , phase out and a neutral to opperate , now with the diagram you have provided i would run the new lites off the existing lights to save confusion , so run the two new lites of the existing.

Now the PIR needs a wire , i would run a compliant cable ( over here i would use a 3 core red, white , blue cabe , making blue the neutral.

Ok run a 3 core cable from each switch to each PIR.

Now the feed would go to the switch , through the switch in the new cable , to the PIR Phase in , then switchs across to another wire back down to the switch , where you would join them with the with a connector with the phase out to the lites that WAS orriginally in the switch.

Connect one core of the 3 cores as the neutral. Now the wall switch will act as an Isolator , which when you have got everything set up with the pirs would be left on.

Ok just to clarify the CCT. Feed into one side of wall switch , through the wall sw , down on one core to the pir , through the PIR , back to the switch on another core which is then joined together with the wires that go to the lites , and the last remaning core is neutral.

Ok now one more thing if you are takling about a METAL pir or a PIR that requires and earth , you will need to run maybe a 4 core , or get an earth from somewhere

Hope this helps , do you understand?
