Types of System
Control Panel Based in accordance with BS7273.
Typically, these systems comprise a “Fire Detection” element and an automatic extinguishant element. Fire detection is installed throughout the protected area and the Detection Control Panel is interfaced with the extinguishant system to trigger an automatic discharge of extinguishant gas under the appropriate conditions.
Systems are usually configured to operate on the “double knock” principle which requires the activation of at least two fire detectors before the extinguishant is released.
PAFSS (Pneumatically Actuated Fire Suppression System)
For smaller protected areas, Fixfire® provides PAFSS units which whilst simpler in concept provide effective affordable fire protection. Fixfire® PAFSS fire suppression systems require no power for detection or to operate. PAFSS detection tubing is installed throughout the risk areas of the enclosure, providing fast and effective detection. Upon flame impingement or high ambient temperature, the pressurised detection tube ruptures with a burst at the hottest point. The extinguishing agent is then discharged from the connected cylinder through the burst hole at the heart of the fire.
Fixfire® provides alternative suppressant options selecting the most suited for any given application.

Fixfire® Fire Suppression System delivering 3M™ Novec™ 1230 Fire Protection Fluid is an environmentally friendly clean agent system, and the solution of choice for protecting people and high value assets.
3M™ Novec™ 1230 Fire Protection Fluid is a proven and reliable fast acting, clean agent solution that is safe for use in occupied spaces. The system is environmentally friendly with zero ozone depletion potential (ODP) and negligible global warming potential (GWP). Fixfire® systems are specifically designed and developed based on independently witnessed fire tests.
3M™ Novec™ 1230 Fire Protection Fluid is listed as “acceptable without restrictions” by the US Environmental Protection Agency’s Significant New Alternatives Policy (SNAP).
Every Fixfire®3M™ Novec™ 1230 installation carries a 20 year environmental warranty.
Fixfire® 3M™ Novec™ 1230 systems work fast and are designed to rapidly absorb heat to the point where combustion ceases. Once actuated, the system delivers the extinguishant within 10 seconds, stopping fires before they have the chance to spread. Most importantly when a fire is suppressed quickly, the result is less damage, lower refurbishment costs and reduced downtime.

2. CO2
CO2 was the original gaseous fire suppression agent and with appropriate safety measures is still used today as an effective and economical solution.
CO2 is the only gaseous agent where the design rules specifically provide guidance on the protection of deep-seated hazards.
Total flooding or local application systems are designed to meet the requirements of NFPA 12 or BS5306-4 and are specifically designed using hydraulic flow calculation software.
The system is VdS approved and components meet the requirements of EN12094 and Pressure Equipment Directive (PED).
- Fast, effective fire protection for critical assets & processes
- VdS Approved
- Tried and trusted
- Versatile & economical
- Worldwide CO2 support
Fixfire® High Pressure Carbon Dioxide Systems are especially effective for non-occupied hazards. Whatever the application, from cylinders to nozzle, each system is custom designed for your specific fire hazards.
High pressure systems use individual storage cylinders that can be manifolded together for rapid simultaneous discharge. Cylinders valves can be operated automatically or manually, and either locally or remotely using electric, pneumatic or mechanical actuators.
To help ensure safety, all personnel must be trained to the safety and operational aspects of the CO2 system.
3. iFLOW Inert Gas
Using innovative technology, the Fixfire® iFLOW Fire Suppression System is a state-of-the art delivery system that provides a regulated and effective discharge of inert gas clean agent. Inert gases are colourless and odourless, safe for people, the environment and cause no damage to property.
The use of inert gases is a proven method for suppressing fire, using naturally occurring gas(es) in areas where people may be present or where valuable or sensitive assets could be damaged by conventional agents.
During a typical inert gas system discharge, a peak pressure and flow spike occurs. It is these peaks that are used to determine the pipe size specification and venting requirements. The Fixfire® iFLOW system eliminates this pressure spike by providing a controlled flow during discharge. This allows for the use of smaller diameter, low pressure piping and reduced pressure relief venting requirements.
An enhancement to the proven agent technology, the innovative Fixfire® if LOW technology is based on three main elements:
The Fixfire® iFLOW valve eliminates the peak pressure and regulates the flow at a nominal pressure of 60 bar in the 300 bar system and 40 bar in the 200 bar version, whilst maintaining the ability to achieve 95% of system design concentration within 60 or 120 seconds.
The Fixfire® iFLOW horizontal check valve minimizes installation time by facilitating the interconnection of containers and in many cases, eliminates the need for a discharge manifold. It also serves as a safety device, preventing loss of agent, in the event the containers are removed from the system during maintenance.
The Fixfire® iFLOW matrix system offers design flexibility and adaptation to complex architectural spaces. When compared with traditional racking systems, the matrix system incorporates a distinctive design that provides more flexibility during installation and quicker removal of containers from the bank, during recharge and maintenance.
4. FirePro
FirePro systems use the latest generation patented FPC solid compound that is the pinnacle of many years of research and development. When activated the FPC solid compound is transformed into a rapidly expanding extremely effective and efficient fire extinguishing condensed aerosol.
The aerosol is propagated and evenly distributed in the enclosure under protection using the momentum generated during the transformation process. Unlike gaseous agents, the total flooding effect is achieved without increasing the pressure in the protected area/volume. Fire extinguishing is accomplished by the interruption of the chemical chain reactions occurring in the flame and not by the depletion of oxygen and/or cooling as suggested by the traditional triangle of fire.
In a typical fire, there is intensive inter-reaction between atoms and fragments of unstable free radicals in the presence of oxygen. This continues until the burning fuel is depleted. FirePro extinguishes fire predominantly by inhibiting on a molecular level the chemical chain reactions present in combustion.
On activation of the FirePro unit, the FPC compound within is transformed into a rapidly expanding fire extinguishing condensed aerosol consisting mainly of Potassium salt-based K2CO3, H2O (vapor), N2 and CO2.
The gas-type, 3-D, properties of the condensed aerosol facilitate its even and fast distribution in the protected volume as well as its flow into the natural convection currents of combustion.
The FirePro fire extinguishing condensed aerosol technology is suitable for Fire Classes A, B, C & F (according to EN2 Classification) and A, B & C (according to NFPA10 Classification).

Room Integrity Testing
It is imperative that the protected area is airtight prior to discharge of the extinguishant. Any openings must automatically seal prior to discharge of the gas. The protected enclosure should be subjected to a room integrity test which involves pressurisation using a computer controlled fan system which detects leakage in the room.
Fixfire® offers Room Integrity Testing at commissioning stage and on an on-going basis following installation.
