pir lighting

[blenki]

Hi , when having 2 lights with integral pir,isthe wiring connections the same as having external pirs, im going to have 2 integral pir lights and i need to wire them so that either sensor turns both lights on,i assume il need 3 core and earth.

yep that sounds about right the 3rd core will trigger the oposite light in either direction
light 1 turns on light 2 and same other way round

As markspark says..the third core is the common linked switchwire.......

One thing to bear in mind if these are to be the 500watt type of halogen fitting , then they will both be operating at the same time consuming a current of approx 4 A....if they are wired from a lighting circuit [as opposed to their own circuit or via a spur off the ring], then you will need to assess the expected loading of the remainder of the circuit, especially if you have multi-lamp type internal fittings or many 50w. downlights etc
