Tips for Maintaining Your FM-200 Fire Suppression System

Maintaining an FM-200 fire suppression system is essential to ensure it functions effectively when needed. These systems play a crucial role in protecting valuable assets and ensuring the safety of occupants in facilities ranging from data centers to museums. Regular maintenance helps extend the system’s lifespan, reduces the risk of failure, and ensures compliance with safety regulations.

1. Schedule Regular Inspections

Routine inspections by qualified technicians are critical to verify that all system components are in good working condition. Inspections typically include checking:

  • Pressure Levels: Ensure cylinders are properly pressurized and within the specified range.
  • Valves and Nozzles: Inspect for any signs of corrosion, leaks, or obstruction.
  • Control Panel: Test the functionality of the control panel and ensure it responds correctly to alarms and activation signals.
  • Detection System: Test smoke or heat detectors to ensure they detect fires promptly.

2. Conduct Annual Maintenance

Annual maintenance should be performed by certified professionals familiar with FM-200 systems. This comprehensive service typically includes:

  • Cylinder Hydrostatic Testing: To verify the integrity of cylinders under pressure.
  • Piping Inspection: Check for leaks, corrosion, or any damage that could compromise the distribution of the FM-200 gas.
  • Nozzle Cleaning: Ensure nozzles are free from dust or debris that could affect the distribution pattern during discharge.
  • System Functionality Test: Simulate activation to ensure all components work together as designed.

3. Keep Records and Documentation

Maintain detailed records of all inspections, maintenance activities, and any repairs performed on the system. Documentation should include:

  • Inspection Reports: Record findings from routine inspections.
  • Maintenance Logs: Document dates, tasks performed, and results of annual maintenance.
  • Certifications and Compliance: Keep certificates of compliance and any relevant regulatory approvals.

4. Train Personnel

Ensure personnel responsible for the facility are trained in the operation and maintenance of the FM-200 system. Training should cover:

  • System Operation: Understanding how to activate and deactivate the system safely.
  • Emergency Procedures: Response protocols in case of a fire emergency and proper evacuation procedures.
  • Maintenance Awareness: Recognizing signs of system malfunction or failure and when to report issues to maintenance personnel.

5. Stay Compliant with Regulations

Stay informed about local regulations and standards governing the installation and maintenance of FM-200 systems. Compliance ensures the system meets safety requirements and operates effectively when needed most.

6. Address Issues Promptly

Address any issues identified during inspections or maintenance promptly. Even minor issues can escalate and compromise the system’s effectiveness during a fire emergency.


Proper maintenance of an FM-200 fire suppression system is crucial for ensuring its reliability and effectiveness. By scheduling regular inspections, conducting annual maintenance, keeping detailed records, training personnel, staying compliant with regulations, and promptly addressing issues, facility managers can maximize the lifespan of their FM-200 systems and enhance fire safety in their facilities. These proactive measures not only protect valuable assets but also safeguard the well-being of everyone within the protected environment.
