How FM200 Fire Suppression System Work
FM-200 (heptafluoropropane) works as a clean agent fire suppression system. Unlike water or foam-based systems, FM-200 extinguishes fires without leaving behind any residue, making it ideal for protecting sensitive equipment. Here’s how FM-200 works to suppress fires:
1. Heat Absorption
FM-200’s primary mode of action is its ability to absorb heat. When a fire burns, it requires a certain amount of heat to sustain the combustion process. Upon release, FM-200 rapidly absorbs this heat, effectively lowering the temperature surrounding the fire.
As the temperature drops below the threshold required for combustion, the fire is unable to sustain itself and is thus suppressed. This disruption of the fire triangle—comprising heat, fuel, and oxygen—ensures that the fire is effectively extinguished. The speed and efficiency with which FM-200 absorbs heat make it a potent agent against fires.
2. Chemical Interruption
Beyond its heat absorption capabilities, FM-200 possesses a unique characteristic that allows it to interfere with the fire on a molecular level. Every fire undergoes a chain reaction, a series of chemical processes that enable it to continue burning. FM-200 disrupts this chain reaction, effectively halting the fire’s ability to propagate.
This chemical interruption is crucial because it ensures that even if some conditions for combustion remain, the fire’s chemical processes are disrupted, preventing it from spreading.
3. Rapid Discharge
The effectiveness of a fire suppression system often hinges on its speed. FM-200 systems are engineered to release the suppression agent with remarkable swiftness, typically achieving full discharge in less than 10 seconds.
This ensures that the agent is distributed uniformly throughout the protected area in a short time frame. Such rapid deployment is vital in ensuring that fires are suppressed before they have a chance to spread or cause significant damage.
4. Safe Concentration Levels
Safety is paramount when considering fire suppression in occupied spaces. FM-200 is formulated to work at concentrations that are non-hazardous to humans. While it effectively reduces the heat and disrupts the fire’s chain reaction, it does so without depleting oxygen levels to a dangerous point.
This characteristic ensures that, in the event of a discharge, individuals within the affected area can safely evacuate without the risk of asphyxiation.
5. No Residue
In environments housing sensitive equipment, the aftermath of fire suppression can be just as concerning as the fire itself. FM-200 stands out because it evaporates completely after discharge, leaving no residue behind. This is invaluable in places like data centers, museums, or medical facilities, where the residue from other suppression agents could be detrimental to equipment or artifacts.
6. Total Flooding
FM-200 systems are typically employed in what’s known as a “total flooding” application. This means that, rather than targeting a specific area or source of ignition, the agent is released to fill and protect the entire designated space. By doing so, it ensures that all potential ignition sources within that space are addressed, providing comprehensive fire protection.
In essence, FM-200’s multifaceted approach to fire suppression, from its heat absorption and chemical interruption capabilities to its rapid discharge and residue-free properties, makes it a highly effective solution. Its ability to act quickly and comprehensively ensures that fires are not only suppressed but prevented from reigniting or spreading further.
Total Flooding is a particularly strategic approach for fire suppression. By filling the entire protected space with FM-200 it ensures that no corner or crevice is left unprotected. This is especially crucial in environments with complex layouts or where fires might originate from multiple sources. The total flooding method ensures a holistic approach, leaving no room for fires to hide or escape the suppression agent.
Moreover, the safety profile of FM-200 is noteworthy. In many fire scenarios, the danger isn’t just from the fire itself but also from the suppression method. Water can damage electronics; foam and powder can contaminate environments and require extensive cleanup. FM-200, on the other hand, offers a clean solution. Its ability to suppress fires without leaving any residue means that once the danger has passed, operations can resume without extensive cleanup or the risk of damage to sensitive equipment.
