PAF-222 clean agent cylinders for a permanent piping network fire suppression system
PAF-222 clean agent cylinders for a permanent piping network fire suppression system

Types of permanent fire protection system piping

The permanent pipe-type fire suppression system uses PAF-222 Clean Agent (FK-5-1-12) as the primary extinguishing agent. It is designed for high flexibility, allowing the system size to be precisely customized to fit the protected area. It is ideal for spaces with installation constraints that still require maximum fire extinguishing efficiency.

Details and features

  • 360-Degree Coverage: Supports nozzle installation in 90°, 180°, and 360° configurations for thorough distribution of the extinguishing agent to cover the entire area.

  • Space-Saving Installation: Supports high pressure up to 4.2 MPa, allowing the use of smaller distribution pipes, making it ideal for limited spaces.

  • Continuous Monitoring: Equipped with a real-time pressure gauge display, allowing constant verification of the system's readiness status.

  • Flexible Application: Designed and customizable in system size to perfectly match the differing dimensions of various protected areas.

  • Eco-Friendly, Life-Safe, and retrofittable: Can be used to replace legacy Halon 1301 and FM-200 systems (subject to engineering calculations and design).

What is a piped fixed fire suppression system?

It is a fire suppression system designed for protecting large areas by using clean agent PAF-222 Clean Agent [FK-5-1-12] to extinguish fires. The system stores the extinguishing agent in fire extinguishing cylinders and high-pressure nitrogen gas cylinders. When a fire occurs, the system discharges the extinguishing agent through a pre-installed piping network to be sprayed from nozzles at various points.

Since this system supports a high working pressure of up to 4.2 MPa, it has the advantage of allowing the use of small-diameter delivery pipes to transport the fire extinguishing agent over long distances efficiently. Additionally, the system features standard safety and monitoring equipment, such as pressure switches, pressure gauges, and overpressure protection devices, to ensure that the system is ready and that its operating status can be monitored accurately.

Who is the piped fixed fire suppression system suitable for?

Organizations or establishments with large protected areas that compact general fire extinguishing systems cannot cover thoroughly.

Data centers or large server rooms that have many equipment racks and require agent discharge piping from a centralized location.

Areas with piping installation constraints. Since the system uses high pressure (4.2 MPa), it is suitable for those who want to save space and reduce the size of the delivery pipes.

Those who want to modify or upgrade their existing systems. For example, those wishing to decommission legacy Halon 1301 or FM-200 systems and switch to the more environmentally friendly and safer PAF-222 Clean Agent [FK-5-1-12] clean agent technology, utilizing the existing infrastructure or making only minor modifications. 

Highlights of the piped fixed fire suppression system

Cabin-type fire suppression systems are designed to fit areas with size, installation space, and structural modification limitations, focusing on ease of use and initial fire response.

Key highlights to consider:

  • Large area coverage and high flexibility: Nozzle placement can be designed and calculated from multiple perspectives (supporting 90°, 180°, and 360° nozzles) to distribute the agent thoroughly and effectively based on the room's layout.

  • Saves space and piping costs: With a high system pressure of up to 4.2 MPa, small delivery pipes can be used, facilitating easy installation in tight spaces and transporting the agent over long distances.

  • High safety and accuracy: Includes built-in pressure gauges and overpressure safety devices, along with 3 operating modes (manual start, automatic system, and mechanical manual bypass).

  • Easy maintenance: The system and agent cylinders feature a modern design, utilizing a secure and easy-to-disassemble cylinder mounting system. This makes routine inspection and maintenance simple and straightforward.

Why clean agents are suitable for enclosed spaces and critical equipment

Enclosed or small areas often have limitations regarding access, ventilation, installation space, and post-incident cleanup. If a fire suppression agent that leaves a large amount of residue is used, it may result in longer downtime for the area and could affect electrical or control equipment inside.

Clean agents, such as PAF-222 Clean Agent [FK-5-1-12], are therefore ideal for areas where post-discharge residue must be minimized, such as control rooms, equipment rooms, cabins, or spaces containing critical equipment, especially when compared to dry chemical extinguishers which can leave powder residue on surfaces, equipment, or ventilation ducts.

However, when choosing to use clean agents in enclosed spaces, the spatial volume, usage patterns, occupancy, ventilation systems, and SDS/Datasheet/Certificates should be verified before actual installation.

How does a piped fixed fire suppression system differ from a cabinet fire suppression system?

Both cabin-type systems and clean agent cabinet fire suppression systems are permanently installed system types, but they are suitable for different spatial contexts.

System Type

Usage Characteristics

Suitable For

Piped Fixed Fire Suppression System

Discharges agent from a central storage cylinder through a distribution pipe network to nozzles at various locations throughout the room.

Large areas or rooms with many corners/blocking cabinets, as piping can be routed to deliver the agent comprehensively.

Cabinet Fire Suppression System

Discharges agent directly from nozzles mounted on the cabinet itself (no piping or only localized short pipes).

Small to medium-sized areas or open layout rooms where the agent from the front of the cabinet can disperse thoroughly.

Frequently Asked Questions (FAQ)

What is a piped fixed fire suppression system?

An automatic fire suppression system designed for overall area protection. Its operating principle is "discharging fire extinguishing agent from a centralized storage cylinder through an installed distribution pipe network using nitrogen gas pressure, then spraying it out from nozzles at various points throughout the room."

What fire extinguishing agent does a piped fixed fire suppression system use?

This system uses PAF-222 Clean Agent [FK-5-1-12].

What kind of spaces is it suitable for?

Large spaces or rooms: Where typical compact fire extinguishers cannot provide adequate coverage.

Rooms with many corners or obstacles: Such as data centers or large server rooms where numerous equipment racks are blocking the way, requiring piping to be routed to discharge the agent from the ceiling or blind spots.

Areas with piping layout limitations: Suitable for those who want to save space along the piping route, as this high-pressure system (4.2 MPa) can use smaller pipe sizes to easily navigate around obstacles.
