Regular maintenance is essential to ensure the continued reliability and effectiveness of an FM 200 fire suppression system. Proper maintenance practices help identify and address issues before they compromise the system’s performance. Below are some key maintenance tips for FM 200 suppression system:

Scheduled inspections:

Establish a regular inspection schedule for the FM 200 system in accordance with manufacturer recommendations and industry standards. Inspections should include visual checks of all components, such as storage containers, piping, nozzles, detection devices, and control panels.

Functional testing:

Conduct periodic functional tests to verify the proper operation of the FM 200 suppression system. Test the detection and alarm systems, control panel functionality, agent discharge mechanisms, and system integration with fire alarm and building management systems.

Pressure checks:

Monitor the pressure levels in FM 200 storage containers and piping to ensure they remain within the specified range. Perform pressure checks regularly using calibrated gauges and instruments. Address any deviations from the recommended pressure levels promptly to prevent system malfunction.

Leak detection:

Implement leak detection procedures to identify and address any leaks in the FM 200 system promptly. Inspect all connections, fittings, valves, and seals for signs of leakage, such as hissing sounds, visible leaks, or pressure drops. Repair or replace damaged components as necessary to maintain system integrity.


Keep the components of the FM 200 suppression system clean and free of dirt, debris, or contaminants that could impair their functionality. Regularly inspect and clean detection devices, discharge nozzles, control panels, and storage container surfaces to ensure optimal performance.

Training and awareness:

Provide ongoing training to facility personnel responsible for operating and maintaining the FM 200 system. Ensure they are familiar with the system components, emergency procedures, and maintenance protocols. Promote awareness of fire safety practices and encourage proactive reporting of any issues or anomalies.

By adhering to these maintenance tips, stakeholders can prolong the lifespan of their FM 200 suppression system, optimize its performance, and ensure it remains reliable in protecting lives and property from the threat of fire. Regular maintenance is key to maximizing the effectiveness and longevity of FM 200 fire suppression systems.
