Self-Contained FM200 Cabinet System with Automatic Activation and ≤10s Spraying Time for Fire Suppression

The FM200 Cabinet Fire Suppression System (also known as a pre-engineered fire extinguishing system) is a self-contained clean agent fire protection unit that integrates the agent storage cylinder, actuation device, piping, and discharge nozzle into a compact cabinet enclosure. It requires no complex pipe network installation and no dedicated cylinder storage room, making it particularly suitable for spaces with limited room or for retrofit projects where extensive construction is not feasible.

The unit can be placed directly inside or adjacent to the protected area and integrated with a fire alarm control panel to achieve fully automatic detection, alarm, and fire suppression. When a fire occurs, the agent is discharged within 10 seconds, rapidly filling the entire protected enclosure to achieve total flooding fire suppression.

• Compact Integrated Design - Saves Space: The system is fully assembled and tested before leaving the factory. The cabinet has a compact footprint - with single-cabinet models starting at just 500×450×1450mm - allowing flexible placement in server rooms, electrical rooms, and other space-constrained environments without the need for a separate equipment room.
• No Pipe Network - Quick Installation: Unlike traditional pipe network systems, this unit requires no complex piping installation. On-site work is limited to positioning the cabinet and connecting the control power supply, significantly reducing installation time. This makes it an ideal solution for retrofit projects and tight construction schedules.
• High Efficiency - Clean and Residue-Free: Using FM200 (HFC-227ea) as the extinguishing agent, the system discharges within 10 seconds, rapidly establishing the extinguishing concentration at the early stage of a fire. As a clean agent, FM200 is non-conductive, non-corrosive, and leaves no residue - ensuring no secondary damage to sensitive electronic equipment and valuable assets.
• Intelligent Integration with Multiple Activation Modes: The system can be integrated with a fire alarm control panel for automatic detection and activation. It supports three activation modes:
  • Automatic Activation: Discharges automatically upon double-confirmation of fire signals from detectors
  • Electrical Manual Activation: Manual start via emergency push button
  • Mechanical Emergency Activation: Direct manual operation of the cylinder valve in case of control panel failure
• Flexible Configuration for Various Enclosure Sizes: Available in both single-cabinet and dual-cabinet configurations, with agent filling capacities ranging from 40kg to 300kg to meet the protection requirements of different enclosure sizes. For larger protected areas, multiple cabinets can be combined to extend protection capacity.

Dual-Cabinet Models: GQQ70×2/2.5, GQQ90×2/2.5, GQQ100×2/2.5, GQQ120×2/2.5, GQQ150×2/2.5, GQQ180×2/2.5 - overall width approximately 1100mm.

1. Fire Detection: Smoke or heat detectors installed in the protected area transmit fire signals to the fire alarm control panel.
2. Signal Confirmation: The control panel activates audible and visual alarms to warn personnel to evacuate, while simultaneously initiating linked equipment (e.g., shutting down HVAC systems and fire dampers).
3. Time Delay: The system enters a delay period (typically 0-30 seconds, adjustable), providing a safe window for personnel evacuation.
4. Agent Release: At the end of the delay, the control panel outputs DC24V to activate the solenoid actuator on the cylinder valve.
5. Total Flooding Fire Suppression: FM200 is discharged through the flexible hose and nozzle, filling the protected area and reaching the extinguishing concentration within 10 seconds for total flooding fire suppression.
6. Signal Feedback: After agent discharge, the pressure switch sends a feedback signal to the control panel, illuminating the discharge indicator light.

FM200 (HFC-227ea) is a colourless, odourless, low-toxicity, non-conductive, and non-corrosive clean agent. Its fire suppression mechanism combines chemical inhibition with physical cooling:

• Chemical Inhibition: Decomposes at high temperatures to release fluorine-containing free radicals, which interrupt the combustion chain reaction
• Physical Cooling: Absorbs a significant amount of heat during vaporisation, lowering the flame temperature

Environmental Properties:

• Zero Ozone Depletion Potential (ODP)
• Short atmospheric lifetime (approximately 36 years)
• Safe for occupied spaces (NOAEL value of 9%)

This system is suitable for small to medium-sized protected enclosures where rapid fire suppression, equipment protection, and cleanliness are critical:

Suitable Fire Types:

• Class A: Solid surface fires (paper, wood, textiles, etc.)
• Class B: Liquid fires or meltable solid fires
• Class C: Electrical fires (energised equipment)

Unsuitable Fire Types:

• Chemical products containing oxidising agents (e.g., nitrocellulose, gunpowder)
• Reactive metals (potassium, sodium, magnesium, titanium, etc.)
• Metal hydrides (potassium hydride, sodium hydride, etc.)
• Self-decomposing substances (hydrogen peroxide, hydrazine, etc.)

Pre-Installation Checks:

1. Verify that the protected enclosure volume meets design requirements
2. Inspect the cabinet for any transport damage
3. Confirm that the model and agent filling quantity match the design specifications

Installation Steps:

1. Cabinet Positioning: Place the cabinet at the designated location within or adjacent to the protected area, positioned securely against a wall
2. Cylinder Installation: Place the agent cylinder inside the cabinet and secure firmly using cylinder brackets
3. Hose Connection: Connect the flexible hose and ensure the nozzle is oriented correctly
4. Power Connection: Route the DC24V power cable into the cabinet and connect to the solenoid valve interface
5. Signal Connection: Connect the signal feedback device to the fire alarm control panel
6. System Testing: Perform a simulated activation test to verify system integration and proper operation

Installation Precautions:

• The system should be installed inside or adjacent to the protected area
• Ambient temperature must remain between 0°C and +50°C
• Avoid direct sunlight and proximity to heat sources
• Ensure sufficient clearance in front of the cabinet for operation and maintenance
• The cabinet must be installed securely to prevent tipping

Routine Maintenance:

• Weekly: Inspect cabinet appearance, indicator lights, and pressure gauge (must remain in the green zone)
• Monthly: Check all connections for looseness or leaks; clean cabinet surfaces
• Quarterly: Test solenoid actuator operation (with agent cylinder isolated)
• Annually: Weigh the agent cylinder - if leakage exceeds 5% of the filling quantity, refill or replace

Post-Discharge Restoration:

After the system has been discharged, professional service is required for restoration:

1. Replace the solenoid actuator on the container valve
2. Re-fill the agent cylinder according to design specifications
3. Re-charge the nitrogen pressurisation to the specified pressure
4. Perform a complete system re-commissioning
5. Reset the fire alarm control panel
