Maintain FM200 system according to NFPA 2001 standards
A properly installed FM200 fire suppression system without regular maintenance is like a rotten umbrella - it looks safe but when needed, it cannot save you. Did you know that just a small error such as a gas leak, a faulty sensor or a stuck valve can disable the entire system, putting your business at risk of billions of dong in property damage and seriously violating fire safety regulations?
So how can you be sure that the FM200 system is always ready to protect you at the right time? Let's find out with KPS the importance of FM200 system maintenance and the optimal solution to give you absolute peace of mind!
Introducing the FM200 system
What is FM200? (Fire extinguishing clean gas - Halocarbon - HFC-227ea)
FM200 (HFC-227ea) is a clean fire extinguishing gas belonging to the Halocarbon group, commonly used in automatic fire extinguishing systems. FM200 was developed to replace Halon – a fire extinguishing agent that has been phased out due to its impact on the ozone layer.
Features of FM200:
- Chemical name: Heptafluoropropane – HFC-227ea
- Extinguishes fires extremely quickly (usually less than 10 seconds)
- Colorless, odorless
- Non-conductive, safe for electronic equipment
- Leaves no residue after discharge, does not cause property damage
- Affects the chemical reaction chain of the fire, extinguishes quickly in just a few seconds.
Applications of FM200 Fire Suppression System
FM200 fire suppression system is suitable for areas with electronic equipment, important data or high-value assets, such as:
- Server room, data center
- Server room, control room
- Document storage room, material warehouse
- Medical equipment room, electronics, telecommunications
- Electrical cabinet, generator room
Why is FM200 system maintenance important?
FM200 gas fire suppression system plays an extremely important role in protecting people, assets and data in important areas such as server rooms, data centers, power stations, storage warehouses, etc. However, if not periodically maintained, the FM200 system may operate ineffectively or not activate when a fire or explosion occurs. Here are the top reasons for regular maintenance:
Ensure the system is always ready to operate
- Check and detect technical errors early such as: gas leaks, stuck valves, incorrect sensors, etc.
- Ensure the system is activated at the right time and in the right way in an emergency
Comply with fire safety standards
- According to international standards NFPA 2001 and Vietnamese standards TCVN 3890, FM200 fire extinguishing systems must be inspected and maintained periodically every quarter and every year
- This is a mandatory condition for the unit to be licensed to operate and accept fire protection
Prolong the life of the equipment
- Equipment such as gas cylinders, sensors, control cabinets, etc., if not inspected, will quickly deteriorate
- Periodic maintenance helps maintain the accuracy and long-term stability of the entire system
Avoid the risk of FM200 gas leakage
- FM200 gas is expensive, if it leaks, it will cause serious economic damage
- Leaks are not timely detection can affect the health of the operator and the environment
Ensure effective fire extinguishing
- The system can extinguish fires quickly within seconds if the sensors and nozzles are working correctly
- Any error can cause the entire system to be disabled when necessary
Minimize legal and insurance risks
- If the FM200 system is not properly maintained, when a fire occurs, it may not be covered by insurance
- Legal burden due to violation of fire prevention regulations

Recommended maintenance time and frequency of FM200
Recommended maintenance time and frequency of FM200 system must comply with international standards (NFPA 2001) and regulations in Vietnam (TCVN 3890, TCVN 5760, ...).
Monthly inspection
- Check the pressure of the FM200 gas tank
- Ensure the discharge valve is sealed, not damaged or missing the label
- Check the error light signal, alarm
- Ensure the power source and backup battery are stable
- Record the pressure index and make a record
Quarterly maintenance (3 months/time)
- Check all heat - smoke - gas sensors
- Clean the nozzle, gas pipe
- Test the discharge simulation function, check the relay
- Check the central control cabinet and the connecting modules
Annual maintenance (12 months/time)
- Calibrate the sensor according to the manufacturer's standards
- Check the FM200 gas volume in the tank by weighing or ultrasound
- Check the tightness of the system - prevent leakage
- Test the simulated system (no gas discharge)
Overall assessment and make a maintenance report - system inspection
Important note:
When the system shows signs of abnormality: gas leakage, warning light error, pressure drop... need to be checked urgently, do not wait until the regular schedule.
After discharging gas (whether test or real), it is mandatory to check, refill gas, and recalibrate the entire system.
Standard technical maintenance process of FM200 system
FM200 system maintenance must be performed according to the correct technical process to ensure absolute safety, avoid gas leakage and maintain effective fire extinguishing ability. Below are the standard maintenance steps applied to FM200 clean gas fire extinguishing system:
Survey the current status of the system
- Determine the location of gas cylinders, nozzles, sensors, control cabinets
- Preliminary check of the operating status of the system
- Assess the risk of leakage, damage or failurei signal deviation

- Recommend solutions (if there is a problem).
- Make a maintenance handover record with both parties' signatures.
Check FM200 gas tank
- Measure tank pressure with a specialized gauge
- Weigh gas mass or use ultrasound to check remaining capacity
- Check tightness, seal, location and inspection stamp
Check central control cabinet
- Ensure cabinet has main and backup power source
- Check indicator light system, alarm siren, emergency button
- Test control relays, activation output, connection module
Check sensors and probes
- Clean dust from smoke, heat, gas sensors
- Check input signal at control cabinet
- Try to simulate fire situation to verify sensor operation
Check sprinkler system and pipeline
- Check gas pipeline for cracks, leaks
- Clean sprinkler, ensure no blockage
- Check bracket, installation location according to design

- Ensure the system responds correctly according to the fire fighting procedure
Record, evaluate and make a maintenance record
- Record all parameters, test results
- Recommend solutions (if there is a problem)
Record, evaluate and make a maintenance record

How much does it cost to maintain an FM200 system?
The cost of maintaining an FM200 fire suppression system can vary depending on the scale, number of gas cylinders, the level of detailed inspection and the service provider. Below are the factors that affect the cost of FM20 maintenance.
System size and configuration
- The more FM200 gas cylinders, the longer the inspection time, leading to increased costs.
- The length of the gas pipe, the number of nozzles, the installation location (on the ceiling, in the electrical cabinet, in the basement, etc.) affect the level of complexity when maintaining.
- Systems with many independent zones and many sensors will require technicians with higher expertise.
System status at the time of inspection
- New, stable systems often have lower costs.
- Old systems that are not regularly maintained often need to replace components and recalibrate sensors, leading to significant cost increases.
- If an FM200 gas leak or a damaged solenoid valve is detected, the repair cost will be calculated separately.
Level of detail of maintenance service
- Basic inspection package: Only general inspection, no system test
- Intensive package: Including sensor calibration, gas mass check, non-discharge simulation test, resistance test... will have a higher price
- Requirements for inspection records, fire protection legal documents also increase costs
Special requests from customers
- Maintenance outside of business hours, at night, or on weekends
- Maintenance areas located in clean rooms, data centers, cold storage, pharmaceutical factories require special construction conditions
- Customers request maintenance without system interruption, still maintaining operations requires more experienced technicians
Location and geographical location
- Inner city areas (HCMC, Hanoi) are usually cheaper
- If the system is located in industrial parks, remote areas, additional travel and accommodation costs for technicians must be calculated
Maintenance frequency according to contract
- Annual maintenance (full package) is usually cheaper than maintenance single time
- Signing a long-term contract (1-3 years) often has a cost discount of 10% - 30%
