I have a project which requires a water curtain be installed on both sides of the glass due to it being the wall down a corridor.
My questions are - (1) does this type coverage require a valve and separate pipe network or can it come off the base building wet system branch lines?
Also, can these same sprinklers be used to cover the corridor as well?
NFPA-13 Section 11.3 doesn't spell this out, so I'm not sure. Thanks in advance.
