Sprinkler heads that are color-coded purple indicate what temperature rating?

Sprinkler heads that are color-coded purple indicate a very extra high temperature rating. This classification is specifically designed to identify sprinkler heads that are suitable for areas exposed to high heat conditions. In fire protection systems, identifying the temperature rating of sprinkler heads is crucial for ensuring effective operation during a fire event; they must activate at appropriate temperatures to suppress flames effectively.

The purple color coding is linked to a temperature range that typically exceeds standard classifications, indicating that these heads will activate at higher temperatures compared to other color codes. Understanding these color-coded ratings helps sprinkler fitters select the correct equipment for specific environmental conditions and ensures compliance with safety regulations and standards.
