Have exits feed from normal panel in hospital. There is no ATS feeding panel. Find it a little odd an maybe even against code that they are fed from normal panel. Think it's considered life safety.

No they aren't. If they are battery back up fixtures they have to be fed from the normal branch, they have to be fed from the local lighting circuit.

Which may or may not be on an emergency panel, local circuit must fail before battery takes over.

Some are some aren't.

If required to be illuminated during normal power failure, then likely considered part of emergency lighting system, though there are signs that don't even require power these days to be visible in low to no light conditions
 
So.. what's the local lighting ckt origin? I would think that's the answer. Whether against code would be a definition of the space.

Whether or not they are required to be illuminated when normal power is lost also would come into this.

I think it is pretty common to put them on with local lighting, but these are not necessarily the same thing as emergency lighting either. Sometimes exit signs aren't even required to be illuminated, just a placard is acceptable, lighted signs often get installed anyway.

Op never mentioned whether this is a hospital, if not the mentioned 517 article doesn't apply though OP did mention life safety, which may or may not mean a hospital is involved.

The OP did state it was a hospital. IMO the exit signs are required to be supplied by the life safety system per 517.33

517.33 Life Safety Branch. No functions other than those
listed in 517.33(A) through (H) shall be connected to the life
safety branch. The life safety branch of the essential electrical
system shall supply power for the following lighting, receptacles,
and equipment.


(B) Exit Signs. Exit signs and exit directional signs.

Correct. Per 517.33 they have to be supplied by the life safety system. They cannot be supplied by the normal system.
