According to UL listed. Most of sprinkler was listed at 13.7 m in height from ground.


But today we also have ASRS that very tall more than 40 m. How do we select the sprinkler?

I know that we need to install in-rack sprinkler but at the top of tier there is no protection.


If we install ceiling sprinkler.It still listed for using in that height?


Or 13.7m that UL listed is measure from top of goods to ceiling?

Thank you
