Hey guys, wanted to run something by you. Inspector called for emergency lights to be installed in a building that is already finished. He did not specify that these needed to be on the lighting circuits in the specific rooms. I have always ran emergency lights off the general lighting circuit but people have told me that the emergency lighting can be on ITS OWN, SEPARATE CIRCUIT. is that code compliant for them to be on a separate circuit, not on the lighting circuit?

No, must be on the lighting circuit. NFPA 70-2014, section 700.12(F)(2)(3).

If they are "unit equipment" lights they must be supplied by the circuit that supplies the normal lighting in the are with an exception that permits a separate circuit from the same panel where three or more circuits supply the lighting in a large room. 700.12(F)(2)(3).
If the lights are supplied by an emergency generator or a central emergency UPS, they would not be supplied by the normal lighting circuits.
