Automatic Fire Suppression Detection Tube - FM200 Based Protection for Cable Trays

FM200 Direct-type Fire Detector Tube​

Product Introduction:
  

   FM200 Indirect Fire Trace Tube System is an advanced automatic fire suppression solution designed for precise and targeted protection of critical equipment. Using clean agent FM200 (HFC-227ea), this system combines early fire detection with controlled extinguishing, making it ideal for applications where accurate agent discharge and enhanced safety are required.

Unlike direct systems, the indirect type uses a fire detection tube to sense heat and trigger a valve, releasing FM200 through a dedicated discharge pipe or nozzle system. This design ensures more controlled and uniform agent distribution, especially in complex or larger enclosures.

Key Features:

• Indirect Activation Mechanism – Detection tube triggers cylinder valve for controlled discharge
• Accurate Fire Suppression – Even distribution through nozzles or piping
• Clean Agent (FM200) – No residue, non-corrosive, safe for sensitive equipment
• Fast Response Time – Rapid activation and fire extinguishing
• Flexible System Design – Suitable for larger or complex protected spaces
• Optional Electrical Integration – Can connect with alarm systems

Main parameters of the fire probe tube:

Performance Characteristics:
  First, the fire extinguishing agent delivery tube has the functions of fire detection, fire extinguishing device activation, and fire extinguishing agent release, eliminating the need for fire alarm and detection devices, thereby reducing costs and installation difficulties, and greatly improving the reliability of the fire extinguishing device, avoiding the false operation of electrical control alarm components.
  Second, this device only implements full-coverage fire extinguishing for equipment that has already caught fire, and quickly extinguishes the fire in a point-to-point manner, changing the situation where traditional gas fire extinguishing systems extinguish the entire equipment space regardless of the size of the fire, resulting in slow detection response time and excessive use of fire extinguishing agents.
  Third, the fire detection tube can be laid inside equipment and instruments that may catch fire, enabling the fastest detection of fires and the fastest point-to-point fire suppression for only the burning parts, resulting in faster response time, less fire extinguishing agent consumption, lower costs, and greater environmental friendliness.
  From the above three characteristics of the temperature-sensing self-starting fire extinguishing device, it can be seen that it is a more scientific fire extinguishing method in terms of improving fire extinguishing efficiency, saving costs, and environmental protection compared to current fixed fire extinguishing devices, especially solid gas fire extinguishing devices.
