Sprinklers manufactured after January 1, 2000, must have what identification feature?

Sprinklers manufactured after January 1, 2000, are required to have a Sprinkler Identification Number (SIN). This requirement is part of the efforts to ensure safety and reliability within fire protection systems. The SIN helps identify and track sprinkler products, which is crucial for maintenance, compliance, and in the event of a fire incident. It allows professionals to determine the specific model and type of sprinkler installed, which can aid in ensuring that the correct functioning and performance criteria are met.

This identification number ensures that in the event of a recall or safety concern, the specific models can be easily identified. The ability to trace back to the manufacturer through the SIN enhances accountability in the industry and reassures users about the quality of the fire protection systems being used.
