Hi
I have to provide emergency light and dual circuit exit sign though and remove all battery packed emergency lights;
In the existing theater that is on the 1st floor of a high rise building;
This building has a stand by generator on the roof that provides 277v circuit for emergency loads; These circuits are on all the time;

I have to extend these circuits to the theater space for emergency lights
How can I control these circuits or during the closed periods so that emergency lights are not on during those periods ???

I thought I can use occupancy sensor all over the space
 
Do you mean e lights that are on when the power goes out? There are relays for that, others should have detail
 
As I mentioned there is a listed emergency light relay, allows lights to be on normal ckt which can be switched. When the normal source is lost, the relay connects to the emergency source to turn light on. I don’t know if this relay can be retrofitted or comes in a prewired luminaire.

How do you Triger those relay automatically??

The unswitched side of the normal circuit powers the relay, just like the inverter in an E fixture uses the 24 hour power to keep the battery charged. Fixture can be switched off and on, but when utility is lost, fixture comes on regardless of switch position.

Basically you will need normal power lead, switched normal power lead, emergency power lead, and an output to the load lead at this relay location, it would be arranged so that if normal power lead is lost, the relay transfers load to emergency power regardless what state the normal operating switch is in.

And regardless if existing EM battery-ballast listed instructions typically prohibit Line-Line voltages, some of those Normal-to-EM leads may have Line-Line voltage, ready to blow up the lights if battery is bypassed.

I wasn't suggesting having the handyman hook it all up :D
