I have to replace a regular exit light with a emergency and exit light and was wondering what to do with the separate emergency feed.
There is no need for that anymore as the fixture will turn ON the emergency light in the case of a blackout.
The new exit light will get 120V from the old circuit but now what to do with the old low voltage circuit?

is there battery back up, and what kind of facility is this?

The separate emergency feed is coming from another battery unit? If so, then you have a new source/Battery I would cap it off and label it or remove it.

The fixture itself would have a battery.

I guess the emergency feed comes from the fire panel but I'm not 100% sure. This is a very old school

How old? Is there a breaker labelled emergency/Exits in the 120v panel?

ive seen them be wired without batteries. one normal feed and one back up generator feed. well? what needs to happen? if theirs batteries, then connect to house power.

Yes, the emergency lights come from the 120/240 panel.

So before you started anything there was already an exit breaker feeding emergency equipment. The existing Exit had not battery in it, so it was probably fed from a battery inside a battery emergency unit (box with two emergency heads on it).

The new Exit combo your putting in already has a battery so I'd say cap off and label the existing DC wire coming from the old battery unit or remove it.

Is this panel fed from the utility side of the main breaker? Pretty common many years ago.
