1. Product Overview & Core Advantages

1.1 Product Overview

The NONFIR Fire Sprinkler series (Models: NF3151 Upright, NF3251 Pendent, NF3351 Sidewall) is a standard-response fire suppression device engineered with a K-factor of 5.6 (80.6) for reliable initial fire control. Designed to comply with global fire safety standards, this sprinkler provides consistent water distribution and rapid heat response, making it a critical component for life and property protection in various building types. It features an intact glass ball with visible bubbles (approximately 1.6mm in diameter) that ensures precise activation at specified temperatures.

1.2 Core Advantages

Multi-International Certification: Fire sprinklers hold FM certification, with other product lines certified by CCC and CE, fully complying with NFPA, FM, EN, Vds, LPCB, and local regulations for global market access.

Superior Performance: Standard response design ensures quick activation; factory test pressure of 500psi (34.5bar) and minimum working pressure of 7psi (0.5bar) guarantee stable operation in emergency scenarios.

Durable Material Selection: Upright and sidewall deflectors are made of copper, while pendent deflectors use S304 stainless steel, ensuring corrosion resistance and long service life.

Flexible Installation Options: Available in upright, pendent, and sidewall types, compatible with 1/2" NPT or ISO7-1 standard pipe threads, adapting to diverse piping layouts.

3. Installation & Maintenance Instructions

3.1 Installation Guidelines

Pre-Installation Preparation: Installation personnel must master sprinkler principles, relevant construction specifications, and manufacturer instructions. Ensure the spray pipe network is fully washed and cleaned before installation.

Timing of Installation: Install the sprinkler after completion of other construction and decoration projects. If modifications or mixed construction are unavoidable, cover the sprinkler with effective protection.

Thread Preparation: When wrapping Teflon film or applying non-curable pipe thread adhesive, avoid the first thread to prevent blockage of the sprinkler orifice.

Secure Installation: Hand-place the sprinkler into the tee joint, then use a 22mm open-end wrench or special wrench to tighten via the base opening. Ensure firm installation and accurate orientation; do not adjust by overtightening.

Protection Clip Handling: Remove the red plastic protection clip (by hand from the side socket, no metal tools allowed) only after all construction is completed and before the sealing test. Reinstall the clip if additional construction is needed post-test.

Post-Installation Check: After tightening, inspect the glass ball for integrity (no leakage or missing working fluid) and confirm the sprinkler arm and deflector are undamaged.

3.2 Maintenance Tips

Regular Inspection: Periodically check for hanging foreign objects, spider webs, or coating damage; clean surface dust with a feather duster (avoid hot water, corrosive cleaners, or ammonia water).

Abnormal Replacement: Replace sprinklers with damaged glass balls (loss of working fluid), dropped units, or disassembled units immediately.

System Maintenance Protocol: Obtain relevant management department approval before closing fire control system valves for maintenance; drain residual water in pipes to avoid water damage during sprinkler disassembly.

Professional Maintenance: Recommended to be performed by qualified inspection institutions or trained specialists to ensure compliance with standards.

4. Packaging & Transportation

Our products are carefully packaged using export-standard wooden crates or wooden pallets to ensure safe transportation. This packaging method provides stability, prevents damage during handling, and guarantees that all items arrive at the customer's location in excellent condition.
