Since the connection point has a large opening and the “K Factor” has to do with the smaller opening size of the fire sprinkler itself then the “K Factor” should be added at the fire sprinkler head itself.
Mike Stewart (843) 490-8366 The K factor has to do with discharge, so it should be applied at the sprinkler, unless noted otherwise by the manufacturer. If they are to be taken at the POC, then the K factor would be modified per length of sprinkler in the literature. Kind of like how Autosprink does it.
Is the k-factor for a dry sprinkler to be applied at the sprinkler, or at the point of connection to the piping network? I understand things like the Victaulic Dry Flex sprinkler have the k-factor at the POC. What about all other dry sprinklers? POC or sprinkler
orifice?
