Exit signs and LEED

[Pat75]

I'm guessing this has been discussed but I can't locate my topic specifically.
In a school kitchen and serving line area there are 3 emergency circuits. Each feed a combination of overhead fluorescent lights and wall mount exit signs.
There is only the emergency circuit in each fixture and sign.
School has back up gen.
The fluorescent lights AND wall exit lights are on a Hubble LX lighting system.
These fixtures and wall exits are switched off at the end of the day.
If power is lost to the LX controller the circuits it controls will remain in what ever state they are in prior to the power failure. If off, they remain off and visa versa. Upon emergency power, the controls can be operated.
I was told that this was compliant.
Maybe I just don't like the fact that the exits can be controlled but can someone help point me to where it meets code and is compliant?

Thanks

I am a retired sparky and would never connect any emergency lighting that could disconnect power to exit or emergency lighting. At a large company that I worked at back in the 1980's I refused to replace halve a dozen emergency lites in the cafeteria that they want to be a quick job by reusing the 120 cord & plugs in old units. Another serious problem that I raised hell about that all of the ceiling lights were on a 277 volt panel. The chief Electrician & 5 other electricians would not back me so they insisted that I had to be wrong. They got one of the other sparkles to take his head out of the sand and do a quickie job. About a year later while at lunch and at least 400 people eating lunch they lost power to the 277 volt panel. The VP of facilities wanted to know how a large building with dual 13,000 volt service and an emergency generator could not provide illumination. Somebody told him to talk to me and I just told him what I said about this. Somebody tried to say all of the battery emergency light packs were bad due to all had the little light on side of enclosure lite up. Stay away from the overpriced bodine battery incased ballast for all lights. At the large hospital/research center that I retired from would always install a date when they were replaced. Way too many went bad in less than 5 years. Bodine came out with a self testing emergency ballast that think it was once a week would cut off switch over to battery power for awhile. Surgeons in OR almost had a baby every time one of these would transfer in middle of an operation. Tried to convince them to never use this model in any of the 20 plus OR'S. I would bring this concern up with the local AHJ or electrical department at local L&I. They do not mind answering questions and rather have things done according to the code.
