Inergen, FM200 & Novec 1230 Suppression
Clean-agent extinguishing systems for server rooms, comms and data-critical spaces.
Why Clean Agent Systems Matter
Server rooms, telecommunications hubs, and data-critical facilities require fire suppression that won't destroy the very assets it's designed to protect. Water-based sprinkler systems cause catastrophic damage to electronics. Clean agent systems discharge gaseous suppressants that extinguish fire without leaving residue, allowing equipment to remain operational after discharge.
FM200 (HFC-227ea), Novec 1230 (FK-5-1-12), and Inergen (IG-541) are the three dominant clean agent technologies. FM200 works chemically by interrupting the combustion process. Novec 1230 combines chemical and physical cooling effects with minimal environmental impact. Inergen is an inert gas blend that reduces oxygen concentration to levels below combustion thresholds while remaining safe for human occupancy.
Annual testing includes cylinder pressure checks, room integrity testing (pressure hold tests), nozzle inspection, and control panel verification. F-Gas regulations apply to FM200 due to its global warming potential, making Novec 1230 and Inergen increasingly favoured for new installations and retrofits.
Compliance Standards
ISO 14520
Gaseous fire-extinguishing systems – Physical properties and system design. Defines agent-specific requirements for FM200, Novec 1230, and Inergen systems.
NFPA 2001
Standard on Clean Agent Fire Extinguishing Systems. Covers design, installation, testing, and maintenance of clean agent systems in the US and internationally.
F-Gas Regulations (EU) 517/2014
Controls fluorinated greenhouse gases. FM200 systems require F-Gas certified engineers for maintenance. Novec 1230 and Inergen are not subject to these restrictions due to lower environmental impact.
Testing & Maintenance Requirements
Room Integrity Testing
Pressure decay testing to verify the protected enclosure can maintain agent concentration for the required hold time (typically 10 minutes). Identifies leaks around doors, dampers, cable penetrations, and suspended ceilings that must be sealed.
Pressure Holds & Cylinder Inspection
Annual weighing and pressure monitoring of storage cylinders. Significant pressure loss or weight reduction indicates leakage requiring cylinder recharge or replacement.
Nozzle & Discharge Testing
Visual inspection of discharge nozzles for blockages or damage. Verification that nozzle positioning matches design calculations. Full discharge tests conducted after installation and every 10 years.
Environmental Regulations (F-Gas Crossover)
FM200 systems require F-Gas certified engineers and leak detection measures. Many organisations are transitioning to Novec 1230 or Inergen to avoid regulatory burdens and align with ESG commitments.
Risks of Non-Compliance
Total Data Loss & Business Interruption
Failed suppression systems allow fire to destroy servers, network infrastructure, and backup systems. Data-dependent organisations can face days or weeks of downtime, with catastrophic financial and reputational consequences.
Inadequate Agent Concentration
Poor room integrity or insufficient agent discharge results in sub-lethal concentrations that fail to extinguish fire. Leaks around unsealed penetrations allow agent to escape, compromising effectiveness.
Legal & Insurance Exposure
Inadequately maintained systems void insurance coverage. FM200 systems without F-Gas compliance can result in regulatory fines. The Responsible Person faces prosecution if fire results in loss due to system failure.
