1.1 Product Overview

The CA-FIRE SN65 Indoor Fire Hydrant is a high-performance, pressure-resistant fire suppression component designed for indoor fixed fire protection systems. As a core part of building fire safety infrastructure, it provides rapid access to water for extinguishing Class A (solid combustibles such as wood, paper, and textiles) and Class B (flammable liquids such as gasoline, oil, and chemicals) fires. With a nominal diameter of 65mm (2.5 inches) and a working pressure of 1.6MPa, this hydrant is engineered to deliver sufficient water flow and pressure for emergency fire suppression in commercial buildings, residential complexes, industrial facilities, and public spaces.

Crafted from high-grade ductile iron-selected for its superior strength, impact resistance, and corrosion resilience-the hydrant features a compact, space-saving design ideal for indoor installation in fire hydrant cabinets. Its vibrant red finish not only enhances visibility for quick identification in emergencies but also provides an additional layer of anti-corrosion protection. Equipped with standard flanged connections, it seamlessly integrates with indoor fire water pipelines, ensuring reliable performance when every second counts during fire emergencies.

1.2 Core Advantages

Premium Ductile Iron Construction: Made from high-quality ductile iron (QT450-10 grade), the hydrant offers 30% higher tensile strength and 50% better impact resistance than ordinary cast iron, withstanding high water pressure and physical impact without deformation or cracking.

High-Pressure Bearing Capacity: Rated for 1.6MPa working pressure, it exceeds the basic requirements of most indoor fire systems, ensuring stable water supply even in high-rise buildings or large-span spaces where pressure loss is a concern.

Dual Fire Class Compatibility: Specifically designed to suppress both Class A and Class B fires, making it a versatile solution for diverse indoor fire scenarios-from office buildings and hotels to factories and warehouses.

Corrosion-Resistant & Durable: The ductile iron body undergoes a three-step anti-corrosion treatment (derusting, phosphating, and high-temperature red powder coating), resisting rust, moisture, and chemical erosion for a service life of 8~10 years under normal use.

Easy Identification & Access: The bright red finish ensures quick location in smoke-filled or emergency situations, while the compact design fits standard fire hydrant cabinets (600×450×200mm) for convenient access.

Standardized Compatibility: Features a 65mm nominal diameter and flanged connections compatible with standard fire hoses, nozzles, and indoor pipelines-eliminating the need for custom adapters.

Certified Quality Assurance: Holding CCC and ISO certifications, the hydrant passes rigorous 型式 tests (type test), initial factory inspections, and post-certification supervision, guaranteeing compliance with GB fire safety standards.

Low-Maintenance Design: With a simple, robust structure and precision-machined valve core, the hydrant requires minimal maintenance-only quarterly visual inspections and annual function tests-to ensure long-term reliability.

3. Installation, Operation & Maintenance Guidelines

3.1 Installation Requirements

Installation Environment: Install indoors in well-ventilated, dry locations with no exposure to direct sunlight, high humidity, or corrosive gases. Avoid low-lying areas prone to water accumulation.

Hydrant Cabinet Compatibility: Ensure the hydrant fits standard indoor fire hydrant cabinets (minimum internal dimensions: 600×450×200mm) with at least 10cm clearance around the hydrant for easy operation.

Pipeline Connection: Connect the hydrant to the indoor fire water pipeline using flanged connections. Use pressure-resistant rubber gaskets and torque bolts evenly in a diagonal pattern to ensure a leak-proof seal. The pipeline must be pressure-tested (at 2.4MPa) before installation.

Orientation & Visibility: Install the hydrant with the outlet facing outward for easy hose connection. Ensure the red finish is visible, and attach a clear "Fire Hydrant" label to the cabinet for quick identification.

Accessibility: Maintain unobstructed access to the hydrant cabinet-no obstacles within 1.5m of the cabinet door, which should open to 120° or more for immediate access.

3.2 Operation Instructions

Pre-Emergency Readiness: Regularly confirm the hydrant cabinet is unlocked, the hydrant valve is closed, and the outlet is free from debris or blockage.

Emergency Operation:

Open the hydrant cabinet door and remove the fire hose.

Connect one end of the hose to the hydrant's 65mm outlet, twisting clockwise to secure the coupling.

Connect the other end of the hose to a fire nozzle.

Rotate the hydrant valve counterclockwise to open it fully, adjusting the flow rate by rotating the valve handle as needed.

Direct the nozzle at the base of the fire and squeeze the trigger to start extinguishing.

Post-Operation Shutdown:

After the fire is extinguished, close the hydrant valve by rotating it clockwise.

Disconnect the hose and nozzle, drain residual water from the hose and hydrant.

Reattach the hose to the cabinet and close the door, ensuring the hydrant is ready for future use.

3.3 Maintenance Recommendations

Quarterly Visual Inspections: Check the hydrant for corrosion, damage, or leakage; verify the valve handle rotates smoothly; ensure the cabinet door opens freely and the label is legible.

Semi-Annual Cleaning: Wipe the hydrant's surface with a damp cloth to remove dust and dirt; clean the outlet threads to prevent debris buildup that could hinder hose connection.

Annual Function Test: Conduct a pressure test at 1.6MPa to confirm no leakage; open the valve fully to check water flow and pressure-address any issues (such as weak flow or leaks) immediately.

Corrosion Protection: Touch up scratched or peeling paint with high-temperature red powder coating to prevent rust; for humid environments, apply anti-corrosion grease to the valve stem annually.

Component Replacement: Replace worn or damaged gaskets, couplings, or valve cores during maintenance to ensure leak-proof performance.

Cabinet Maintenance: Keep the cabinet clean and dry; replace damaged cabinet doors or locks promptly to protect the hydrant from damage or tampering.
