2L Storage Container Capacity Rack Fire Suppression Unit with 1.6 MPa Storage Pressure for 0℃ to 50℃ Applicable Environment Cabinet Fire Suppression

The FM200 Cabinet Fire Suppression System is a pre-engineered, all-in-one fire detection and extinguishing unit specially designed for enclosed cabinets and rack environments. It combines fire detection, clean agent storage, discharge nozzle, pressure indicator, and signal feedback into one compact module, making it ideal for server racks, electrical control panels, telecom cabinets, UPS cabinets, and other confined equipment spaces.

Using HFC-227ea (FM200) clean agent, the system rapidly suppresses Class B, C, and electrical fires without leaving residue or damaging sensitive electronic equipment.

• Fast automatic fire detection and suppression
• No external power supply required
• Clean agent — non-conductive and residue-free
• Compact drawer-type installation
• Independent protection for single or multiple cabinets
• Space-saving design — no separate cylinder room required
• Cost-effective solution for cabinet-level fire protection

Designed specifically for limited-space environments, this system eliminates the complexity of traditional centralized fire suppression systems.

When the cabinet temperature reaches the preset level (68℃ or customized), the glass bulb bursts automatically, releasing FM200 agent instantly.

The fire detection tube ruptures at the hottest point when exposed to flame, triggering the discharge of the clean agent directly at the fire source.

2. Inside server cabinets for telecommunications and communication systems
3. Inside control cabinets for banking equipment
4. Various control cabinets for machinery and other industries

Install the cabinet heptafluoropropane gas fire extinguishing device in a drawer-style arrangement into the cabinet and secure it firmly, as shown in the figure above. The thermal release assembly and fire detector tubes are also arranged as illustrated. The thermal release assembly is secured to the cabinet using the corresponding accessories. The fire detector tubes should be arranged in an S-shaped pattern, preferably in areas prone to fire, and secured with cable ties.

Personnel performing installation, commissioning, and operation should be familiar with the basic structure, operating principle, performance, and operating procedures of the device, as well as the structure and operating conditions of each valve component.

The device should be installed away from direct sunlight and heat sources. Ensure that the device is not subject to vibration and impact. The device should be secured within a protected area using brackets.

4.1 Installing the Heptafluoropropane Gas Fire Extinguishing System in the Cabinet

4.1.1 Selecting a Location: Select a suitable U-shaped space in the upper area of the cabinet. The location should be convenient for daily inspection and installation, avoiding areas with heavy wiring.

4.1.2 Securing the System: Use the cabinet's built-in rails or tray to secure the system. Secure the system with screws through the two screw holes on the front panel. Once secured, the system is installed.

4.2 Components and Installation

4.2.1 The system interfaces include: copper pipe interface, switch, pressure gauge, signal feedback device, fire detector tube, temperature-sensing glass bulb, and fire extinguisher release nozzle. The fire extinguisher release nozzle is located on the front panel, and the other interfaces are located on the back panel.

4.2.2 Installation of the Temperature-Sensing Glass Bulb and Fire Detector Tube:

4.2.2.1 Temperature-Sensing Glass Bulb: The temperature-sensing glass bulb is already fixed to the device and does not require installation.

4.2.2.2 Fire Detector Start Pipe: Remove the plug from the air throttle, insert the fire detector tube into the pin-shaped connector, and tighten the copper cap until secure. Observe the cabinet space and select an appropriate piping layout. The piping layout principles should first ensure maximum cabinet coverage, then route the fire detector tube through the most fire-prone areas, and finally consider aesthetics. The fire detector tube ends in a standard plug. First, insert the internally threaded plug into the fire detector tube. Then, firmly insert the other plug into the fire detector tube. Connect the two pieces and tighten.

4.3 Signal Feedback Device Interface

Connect the signal feedback device to the system according to the marking requirements.

A dedicated maintenance manager should be assigned to manage the maintenance of cabinet heptafluoropropane gas fire extinguishing devices. Maintenance records should be kept. The manager should be familiar with the device's operating principles and performance.

a. Inspections should be conducted twice weekly and meet the following requirements:

• The pressure reading on the device should be within the green zone.
• The switch on the container valve should be in the "on" position.
• The device should show no abnormalities.

b. Device components should also be inspected quarterly and meet the following requirements:

• Device components should be free of mechanical damage and surface rust; coating protection should be intact, and nameplate markings should be legible.
• The fire extinguishing agent container, fire detection hose, release hose, nozzle, etc. should be secure and reliably connected.

c. Conduct a comprehensive annual inspection and maintenance of the cabinet gas fire extinguishing system. In addition to meeting the requirements in a and b, the following requirements must also be met:

• Check the fire extinguishing capacity of the device's container by weight. Requirement: fire extinguishing capacity ≥ (container volume × 1.15 g/L) × 90%. If the requirement is not met, refill the fire extinguishing agent.
• Observe the pressure gauge to check for leaks in the cabinet's HFC-227ea gas fire extinguishing system. If the pressure gauge is outside the green zone, check the fire extinguishing capacity by weight. If the fire extinguishing capacity loss is ≥ 10%, consider replenishing the fire extinguishing agent and restoring the pressure.
• The fire detection tube must be free of deformation, corrosion, damage, or aging.
• Maintenance and management of the fire extinguishing agent container must be carried out in accordance with the "Safety Supervision Regulations for Gas Cylinders."
