[QUOTE="Whit263, post: 554084, member: 37831"] Hi Guys, So i’m wiring LCM lights with emergency fittings and PIRs. I have a 4 core supply going straight to the LCM box, then the PIR and the lights just plug off the LCM which is straight forward. However in my head i had the thought process of putting a key switch and a 2 way switch back at the board, but was told that won’t work by a colleague, and that you just need a key switch because of the PIRs. Struggling to wrap my head around it, havent done emergency lighting in a while. So is it a case where the permanent live and the switch live going to the LCM Box will both go in the load side of a double pole key switch? And then bridge/link the common with a bit of cable? Or have i got that wrong? Thanks Guys [/QUOTE]
