FM200 gaseous suppression systems: selection and application guide
FM200 (HFC-227ea) is a clean-agent option considered for enclosed spaces where water and powder residue can be problematic. Agent quantity and distribution are determined from net volume, fire hazard, openings and the selected system design data.
FM200 (HFC-227ea) is a colourless, odourless and non-conductive gaseous suppression agent that leaves no solid residue when correctly designed. It is designed with cylinders, pipework, fixed nozzles, detection and control for enclosed areas containing electronic equipment, including data centres, server and UPS rooms, archives, museums, transformer rooms, ship engine rooms and critical production spaces.
01
Engineering and commissioning steps
Selection considers the product function, the protected risk and operating conditions together. These steps support the site survey and quotation.
Defining the protected space
Survey net room volume, raised-floor or ceiling voids, cabinets and cable penetrations. Include permanently open areas and ventilation in feasibility assessment.
Agent, piping and nozzle calculations
Determine cylinders, agent quantity, pipe route and nozzle distribution using the selected system calculation method. Pressure or discharge data from one system is not transferred to another agent or model.
Detection, evacuation and interlocks
Define detection and any cross-zone confirmation, pre-discharge warning, evacuation, manual controls and ventilation/power interlocks in the cause-and-effect scenario.
Integrity and handover checks
Check enclosure integrity and required retention conditions using the selected design tests. Calculate pressure-relief needs and hand over test records for alarms, interlocks and release controls.
02
Applications and site planning
These examples show why placement and equipment requirements can differ between facilities using the same product.
Server and control rooms
- Site requirement
- Electronic equipment, ventilation and cable penetrations.
- Application approach
- Plan enclosure integrity and power/ventilation behaviour with agent distribution calculations.
Archives and sensitive equipment spaces
- Site requirement
- Residue sensitivity, storage layout and enclosure openings.
- Application approach
- Assess fuel compatibility and agent retention together, with nozzle placement accounting for racks and equipment obstructions.

| Check item | Product / application | Information to assess |
|---|---|---|
| Agent | FM200 (HFC-227ea) | Hazard, system model and technical documentation |
| Protection boundary | Defined enclosed volume | Volume, openings and adjacent spaces |
| Personnel safety | Evacuation and pre-discharge warning | Access, manual controls and operating plan |
| Commissioning | Calculations, installation and function tests | Enclosure integrity, interlocks and pressure relief |
Gaseous protection requires more than naming an agent and selecting cylinders. We can define the facility scope through a coordinated survey, flow calculation, detection scenario and operating-safety assessment.
