When are ornamental finishes permitted on sprinklers?

Ornamental finishes on sprinklers are permitted only if they are applied by the sprinkler manufacturer and are listed with such a finish. This requirement ensures that any modifications to the sprinkler's finish do not interfere with its performance or effectiveness.

Applying the finish at the manufacturer level ensures that the sprinkler has been tested and certified to maintain its operational standards, even with the decorative coating. By listing these finished products, it provides transparency and assurance to users that the sprinklers meet safety and performance regulations.

This approach prioritizes adherence to code and safety standards while allowing for aesthetic customization, which can be important in settings where the visual appearance of fire protection systems matters.
