Perfluorohexanone Fire Detection Tube Fire Suppression System | Frequently Asked Questions

Q1: What types of environments are suitable for perfluorohexanone fire‑extinguishing tube systems?

A1: Suitable for enclosed, confined spaces such as distribution cabinets, energy storage battery enclosures, control cabinets, and cable trays; effective for extinguishing initial electrical fires, but not suitable for fires involving reactive metals.

Q2: What is the operating principle of a fire-detection tube extinguishing system?

A2: The fire detection tube is installed within the protected area. When exposed to a high-temperature ignition source, the tube wall ruptures, releasing perfluorohexanone extinguishing agent to rapidly suppress the fire at its origin, thereby achieving… Fixed-point fire suppression 。

Q3: What startup methods does this system support?

A3: Primarily activated automatically by the thermal‑sensitive rupture of the fire‑detecting tube; it can also be equipped with an electrical detection module and connected to an alarm system for linked activation.

Q4: Will the perfluorohexanone agent damage the precision electronic components inside the cabinet?

A4: The agent is clean and leaves no residue, exhibits excellent insulation properties, does not corrode precision components after discharge, and the equipment can be restored to service once ventilation has been completed.

Q5: How long is the shelf life of the medication, and does the vial need to undergo a hydrostatic pressure test?

A5: The pharmaceutical agent exhibits chemical stability; pressure‑type containers undergo periodic hydrostatic testing in accordance with applicable standards, while non‑pressure‑type containers do not require cylinder hydrostatic testing and should be replaced according to the product’s service life.

Q6: What are the requirements for the arrangement of fire detection tubes?

A6: The fire‑detecting tube shall be installed in close contact with components prone to overheating and ignition, avoiding sharp edges and corners, and ensuring that it can rupture normally when heated to meet the required protection coverage.

Q7: After the system has discharged, can the fire detection tube be reused?

A7: Once the fire detection tube ruptures and releases its extinguishing agent, it becomes inoperable; it is a single-use component. After fire suppression, both the fire detection tube and the extinguishing agent assembly must be replaced.

Q8: Do gaps in the protected area affect fire suppression effectiveness?

A8: The fire‑detecting tube provides localized, fixed‑point fire suppression and should still be designed to minimize the release of extinguishing agent. Excessive gaps can reduce the local extinguishing concentration, thereby compromising fire‑suppression effectiveness.

Q9: Can the perfluorohexanone agent be disassembled, reassembled, and refilled independently?

A9: No. Refilling the fire‑extinguishing agent and performing pipeline maintenance must be carried out by a qualified fire‑protection contractor; unauthorized disassembly or reassembly may render the system inoperable.

Q10: What routine maintenance checks should be performed?

A10: Regularly inspect the fire detection tubing for signs of wear, compression, or damage, and check the cylinder‑group pressure gauge. Have the entire system tested annually by a qualified maintenance provider.
