There is technically no limit on the height at which most sprinklers can be utilized. The more usual situation is when a specific sprinkler has a specific listing limiting its usage to a certain height.
The number your memory is serving to you comes from the Life Safety Code and references a height of 55ft. However, it doesn't LIMIT you by the standard. It only directs you to give consideration to the fact that the height may cause a delay in the sprinkler activation. The considerations may be to increase your design area, design density, or both to more reliably control a fire in areas where the ceiling is at more extreme heights.

I've spoke with the manufacturer and he said he doesn't have anything on min./max. ceiling heights. If memory serves me isn't 50' somewhere in NFPA? Any help would be appreciated.
