The emergency light must have a switched feed (normal on/off) and a permanent feed for battery charging & supply monitoring. The permanent feed should be wired via a test key switch for maintenance.

How you achieve that depends on how you are wiring the lights.

Twin and earth is fine for emergency lighting as long as it meets all other requirements relating to the installation/building.
