III. Composition and Technical Parameters of the Fire Extinguishing System

1. Composition of the perfluorohexanone pipeline-type fire suppression system

The perfluorohexanone pipeline‑type fire suppression system consists of nozzles, release piping, container valves, solenoid valves, and a fire‑extinguishing agent cylinder assembly. This system is an independent total‑flooding fire suppression system and offers both automatic and manual activation modes.

2 Technical Specifications

2.1  Fire suppression system Technical Specifications

Fire suppression system Technical Specifications  

2.2 Fire extinguishing agent cylinder assembly

1) Purpose

It stores the extinguishing agent under normal conditions, and when a fire occurs, the container valve activates to release the extinguishing agent.

2) Composition

It consists of a fire-extinguishing agent, a gas cylinder, a container valve, a pressure gauge, a safety relief device, a siphon tube, and other components.

3) Operating principle:  

In the event of a fire, the electromagnetic actuator opens the container valve, allowing the extinguishing agent to be discharged from the valve and conveyed through piping to the protected space via the nozzles.

4) Features

a. The cylinder assembly is equipped with a safety relief device to prevent hazards caused by excessive pressure inside the fire-extinguishing agent storage cylinders.

b. The entire device features a well‑designed, safe, and reliable structure, with simple maintenance.

c. The extinguishing agent can be refilled multiple times.

5) Installation, Usage, and Maintenance Instructions and Precautions

a. During transportation and installation, the extinguishing agent cylinder assembly should not have the solenoid‑actuated actuator mounted on the container valve until after these operations are completed, to ensure safety. Handle with care, avoid impacts, and keep out of direct sunlight.

b. The fire-extinguishing agent cylinder assembly shall be securely fastened.

c. After the installation of the electromagnetic actuator, the container valve shall be equipped with both automatic and mechanical emergency activation modes.

d. The pressure within the cylinder assembly must remain within the green zone of the pressure gauge. If the pressure falls below the lower limit of the green zone, the cause of the leak must be identified and the system recharged.

e. The design, manufacture, acceptance, use, and periodic inspection of fire-extinguishing agent cylinders shall be conducted in accordance with the provisions of the current “Safety Technical Supervision Regulations for Gas Cylinders.”

f. Maintenance and management shall be carried out in accordance with the requirements of GB 50263-2007, “Code for Construction and Acceptance of Gas Fire‑Extinguishing Systems.”

2.3 Electromagnetic Actuator

1) Working Principle

When a fire alarm is triggered, the DC power output by the fire alarm control panel activates an electromagnet. The electromagnet then releases the actuating mechanism, causing the operating mechanism to move and simultaneously opening the top‑rod linkage, which in turn actuates the valve or container valve to release the control gas or extinguishing agent.

2) Structure

It consists of an electromagnet, a release mechanism, and an actuation mechanism.

3) Main performance parameters:

In an emergency, you can pull the safety‑lock lever with your finger to disengage the lock, then strike the manual button to activate the actuator valve or container valve.

Special note: After the electromagnetic actuator has passed inspection, the spring in the operating mechanism is already compressed. To prevent unintended operation during installation, commissioning, and transportation, the operating mechanism is secured by a safety locking pin. Once the entire system has been installed and commissioned and is ready for service, the safety locking pin must be unscrewed, reversed, and securely reinstalled; otherwise, the electromagnetic starter’s operating mechanism will fail to function.

IV. Equipment Installation and Commissioning

1) Place the YF series perfluorohexanone pipeline fire suppression system securely in its designated location and ensure it remains fixed.

2) Install the electromagnetic actuator and the release piping assembly, connect the wiring to the fire suppression control panel, and verify that the wiring is correct. Connect the wires from the smoke and heat detectors to the fire suppression control panel.

3) Commissioning of the fire suppression system.

4) After the fire suppression system has been commissioned and is ready for operation, remove the safety pin that automatically activates the electromagnetic actuator.

Pipeline‑Type Perfluorohexanone Fire Suppression System | Frequently Asked Questions

Q1: What types of protected areas are suitable for pipeline‑type perfluorohexanone fire suppression systems?

A1: Suitable for enclosed protected areas such as large and medium-sized computer rooms, distribution rooms, energy storage compartments, and archives; it is effective for extinguishing electrical fires but not suitable for fires involving reactive metals or strong oxidizers.

Q2: What are the characteristics of pipeline‑type perfluorohexanone?

A2: This system uses a pipework network to deliver the extinguishing agent, with the cylinder banks centrally located. The agent can be conveyed through piping to multiple protected zones, making it well suited for large‑area, multi‑zone centralized protection.

Q3: What startup methods does the device support?

A3: It supports three operating modes—automatic interlock start-up, on-site manual start-up, and mechanical emergency start-up—complying with relevant fire safety regulations.

Q4: Does the discharge of perfluorohexanone extinguishing agent damage precision equipment?

A4: The agent is clean and leaves no residue, exhibits excellent insulating properties, does not corrode precision electronic components, and allows equipment to resume operation promptly after ventilation.

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

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

Q6: Do gaps in the protected area affect fire suppression effectiveness?

A6: Yes. Prior to discharge, all doors, windows, and ventilation openings in the protected area must be closed to minimize agent leakage and ensure that the design extinguishing concentration is achieved within the protected space.

Q7: During the system’s discharge delay period, may personnel remain inside the protected area?

A7: No. Personnel must evacuate during the delay period, and entry into the protected area is strictly prohibited after discharge to prevent inhalation of the agent’s vapors.

Q8: Can the perfluorohexanone agent be disassembled, reassembled, and refilled independently?

A8: No. Refilling fire‑extinguishing agents and performing maintenance on the piping network must be carried out by a qualified fire‑protection contractor; unauthorized operations may render the system inoperable.

Q9: Can a single piped‑type perfluorohexanone system protect multiple protected zones?

A9: It can be paired with a selection valve to enable a single cylinder bank to protect multiple independent protected zones, with discharge into the corresponding zone selected based on the fire situation.

Q10: What routine maintenance checks should be performed?

A10: Regularly inspect pressure gauges, pipelines for leaks and corrosion, and the status of the alarm control panel; conduct system testing annually by a qualified maintenance provider.
