Protect Critical Assets Without Water Damage
FM200 gas suppression extinguishes fires in seconds without leaving residue, water damage or downtime. C4 Fire & Security designs, installs and maintains FM200 systems for server rooms, data centres and high-value environments across the Western Cape.
Zero Water Damage
FM200 suppresses fires as a gas, leaving no residue or water. Your equipment, documents and data stay dry and undamaged.
Extinguishes in Seconds
FM200 reaches extinguishing concentration within 10 seconds of discharge, stopping fires before they spread.
Safe for Occupied Spaces
At design concentration, FM200 is safe for occupied spaces. No evacuation needed before discharge.
FM200 Gas Suppression Systems
FM200 (HFC-227ea) is one of the most widely used clean agent fire suppression systems worldwide. It extinguishes fires by absorbing heat energy faster than the fire can generate it. C4 Fire & Security designs FM200 systems to SANS 246 standards for server rooms, UPS rooms, archives, laboratories and any space where water or powder suppression would cause more damage than the fire itself.

Typical clean-agent cylinder bank install
How It Works
Room Assessment
We measure the protected space, assess seal integrity and determine the correct agent quantity.
System Design
Engineers design the pipe network, nozzle placement and cylinder sizing to SANS 246 standards.
Installation
Professional installation of cylinders, piping, nozzles, detection and release panels.
Commissioning
Room integrity testing, full system discharge simulation, compliance documentation and training.

-
FM-200 chemistry
Clean, electrically non-conductive, leaves no residue after discharge.
- Heptafluoropropane (HFC-227ea)
- Design concentration around 7 percent by volume
- Suppresses fire by heat absorption and chemical interruption
- Safe for occupied spaces at design concentration
- Discharges fully in 10 seconds
-
Cylinder sizing
Cylinder capacity is calculated from room volume and design concentration.
- Volume of the protected space (length x width x height)
- Subtract any non-fillable volume (large equipment)
- Apply temperature correction for the space
- Round up to the next standard cylinder size
- Spare cylinder programme recommended for critical sites
-
Room integrity
Without a good seal the agent escapes before it can do its job.
- 10-minute hold time at design concentration is the goal
- Door fan test before commissioning
- Floor, ceiling void and cable penetrations must seal
- Doors automatic-closing with magnetic hold-open
- Annual integrity re-test required by SANS 14520
-
Cover area limits
FM-200 is right for most enclosed risks up to a few hundred cubic metres.
- Server rooms, comms rooms, data centres
- MCC, switchgear and generator rooms
- Telecommunications and broadcast suites
- Cash vaults and document archives
- Above ~1500 m3 Inergen becomes more cost-effective
-
Discharge time
FM-200 fills the protected space to design concentration within 10 seconds.
- Discharge nozzles sized per cylinder bank
- Pipework calculated for balanced flow
- Pressure relief venting for the protected space
- Pre-discharge alarm and 30-second time delay
- Automatic shutdown of HVAC on activation

Frequently Asked Questions
Yes. At the design concentration used for fire suppression (7-8% by volume), FM200 is safe for occupied spaces. However, we always integrate detection and alarm systems to alert occupants before discharge as a safety precaution.
FM200 systems require 6-monthly inspections, annual full-system testing, and room integrity verification. The gas cylinders should be weighed annually to check for leaks. C4 provides maintenance contracts covering all requirements.
The gas is non-toxic and leaves no residue, so there is no cleanup needed. However, the system needs to be recharged before it can protect the room again. C4 provides fast recharge services to minimise your exposure window.
