UL has issued a notification to distributors, contractors, fire departments, regulatory agencies, and authorities having jurisdiction of a fire sprinkler that bears a counterfeit "UL Mark" for the United States and Canada.
The sprinkler identified in UL Sprinkler Public Notice Release 13PN-06 is provided with a counterfeit "UL Mark." Especially important to home fire sprinkler advocates, it is unknown if the sprinklers were distributed or marketed for residential use, according to UL spokesperson Carla Swanson. “The fire sprinkler has not been evaluated by UL to the appropriate standards for safety and it is unknown if the fire sprinkler complies with any safety requirements,” said Carla.
The counterfeit fire sprinkler can be identified by "NX" and "C-I" marking on the wrench boss of the fire sprinkler frame and may have model NX005 on the sprinkler deflector. Sprinklers manufactured by Nanjing Fire Protection Technology Co Ltd that are authorized to bear the "UL Mark" do not have "NX" and "C-I" marking on the wrench boss.
