Is it code to have lighting circuits fed from inverter in different conduits that lights feed from normal lighting panels ?

I believe that the inverter output circuits are considered emergency circuits which would require separation.

Always a spec thing but NEC requires EM circuits to be separate from normal?
"emergency circuits" is somewhat a relative term. Art 700 addresses true "emergency" circuits but the term is often used for Art 701 Legally Required and Art 702 Optional Standby and the mixing of circuits is handled differently within those Articles. You need to determine what class of system you are working with, true "emergency" or Art 701, 702.

So theres true emergency , legally required and optional standby?

Look at 700.9(B) 2008 NEC.

The NYC code amendments removed legally required standby. Someone told me that there has been an update to this but I'm not sure if that's true.

So the amendments did not remove optional?

Anyone else have input whether inverter circuits need to be in separate conduits ?

No but you're inverter is likely not providing optional standby.
I thought that was answered. It depends on the classification of the circuit (area) as to it being a true "emergency" circuit or otherwise.

No it's providing constant power to EM fixtures or I'm wondering if it's just back up. I don;t think so based on floor plan circuit/panel desgination.
The inverter does have a separate cabinet with batteries but I think that in case of power loss.

Yea, guess your right. Need to determine that. Article 700 will clarify what "true" emergency is considered?
Barring any NYC changes noted in Post#8:
Emergency Systems. Those systems legally required and classed as emergency by municipal, state, federal, or other codes, or by any governmental agency having jurisdiction

To me that vague. How do I determine that ?
Engineer/architect should have already done so,.
The fact that the circuit is labeled "EM" would lead me to believe it was emergency but infinity is well versed in these matters,.. see what he says,

There needs to be EM egress lighting it's highly likely that is what is depicted on the drawing which makes it EM.

Needs to be EM egress lighting for what?

Lighting for egress. When an emergency happens you need to be able to see the way out. You definitely need separate conduits
