This is probably an easy question for you guys but here goes:

Lets say I have two lights controlled by one vacancy sensor/single pole switch. One light is normal and the other is emergency egress. In the case of a power outage, full power must be applied to the egress light. The product to accomplish this is an EELP RLS.

I am assuming there would need need to be a 2 circuit power pack for my normal and emergency circuit? But where exactly does the above mentioned relay come into play? How would it be wired?

Thanks guys in advance, if you need anymore info, I’ll be glad to add it.
