Emergency Lighting
(OP)
I'm designing the electricl lighing and exit signs for a stairway in an office building. I have spec'ed out exit lights and stair lights with battery backup in each fixture. My question is because I have battery backup in each device, do these fixtures have to be feed on their own circuit? or can I just tap of an existing circuit?

That said, check your code!

If dedicated circuits are used, they and normal light circuits need to arranged such that loss of any one circuit shall not cause loss of all normal lights in the area.

In my case the battery is the "emergency circuit" so the "normal supply circuit" can feed the emergency lights along with the hall way lights leading up to the stairway.
