Hey guys,
How do you all wire your emergency lighting?
Option 1. When the key switch is switched, ALL lights go off and the emergencies stay on.
Option 2. The lights operate as normal when the key switch is switched but the emergencies switch to emergency mode.
With option 2, am I correct in thinking there are 2 permanent lives from the DB (brown & black), the black is the PL to the fitting (via a key switch) and the brown is the SL via a switch, PIR etc? What I cant understand is how the fitting goes into emergency mode when the key switch is switched if the fitting also has a SL from a PIR etc. Do I have to switch both via a double pole key switch???
I am probably overthinking this TBH.
Thanks in advance.
