FM-200 (HFC-227ea) is a colorless, odorless, non-corrosive, and electrically insulating extinguishing agent that leaves no residue or pollution after discharge. Its Ozone Depletion Potential (ODP) is zero, making it an environmentally friendly choice for fire suppression. These properties make it particularly suitable for protecting areas where electrical fires are likely to occur.

When combined with the extinguishing device and electronic accessories, the entire system can be actuated automatically. It monitors the protected area through detectors and triggers the extinguishing device via a solenoid actuator, achieving full automation. This eliminates the risk of an unnoticed fire and reduces the cost of staffing personnel to supervise the protected area.

The system is ideal for protecting sensitive and high-value environments, including:

• Electronic computer rooms and data processing centers
• Telecommunications facilities and process control rooms
• Expensive medical equipment and industrial equipment
• Libraries, museums, and art galleries
• Clean rooms and anechoic chambers

It is also well-suited for high-risk fire environments such as paint-spraying production lines, aging electrical equipment, rolling machines, printing machines, oil switches, oil-immersed transformers, melt impregnating tanks, large generators, drying equipment, cement production pulverized coal processes, ship engine rooms, and cargo holds.

• Versatile agent: Effective against all classes of fire except metal fires, and leaves no residue or pollution after extinguishing.
• Rapid discharge: The entire agent is discharged in under 10 seconds, achieving full flooding of the protected area almost instantly.
• Built-in time delay: A delay mechanism of approximately 2 minutes provides ample time for personnel to evacuate the hazardous area after a fire is detected.
• Simple installation: Unlike piped network systems, this cabinet-type unit requires no pipeline installation, significantly reducing installation complexity and cost.
• Cost-effective for small zones: Ideal for protective zones that are relatively small or cover no more than three zones, offering substantial savings compared to piped network systems.

The illustration below demonstrates the working principle of the complete system.
