FM Approved vs. Self-Certified:
The Difference Buyers Pay For
Buyers specifying FM approved fire sprinklers are not looking for "equivalent" or "meets standard" — they require the FM Approvals mark. Insurance underwriters, EPC contractors, and AHJs in the Middle East, Southeast Asia, and North America routinely mandate FM listing by name.
How Our FM Approved Sprinklers Are Made
Transparency matters to specifiers and procurement teams. This video walks through our Fujian manufacturing facility — covering the production process, assembly quality controls, and factory hydro-test procedures that back every FM approved sprinkler head we ship.

What Is an FM Approved Fire Sprinkler?
An FM approved fire sprinkler is a sprinkler head that has been independently tested and listed by FM Approvals — a globally recognized certification body — against FM Standard 2030. The FM approval mark confirms that the product has passed rigorous performance, durability, and reliability testing beyond the minimum requirements of local standards.
NONFIR's FM approved sprinkler heads (SIN series NF31xx, NF32xx, NF33xx) are manufactured by CA-Fire Protection Co., Ltd. in Fujian, China and are available for direct export. All products are factory hydro-tested before shipment and carry traceable documentation.

Our FM approved pendent sprinkler range covers both standard response (5mm glass bulb, SIN NF3251) and quick response (3mm glass bulb, SIN NF3231). Both feature chrome-plated brass frames with copper or stainless steel deflector options, K-factor 5.6 (K80), and ½" NPT thread — fully compatible with NFPA 13 commercial system designs.
