Use and maintenance instructions

 

Cylinder Valve Assembly (Agent Cylinder Kit)

3.1 When the valve needs to be opened manually, the valve can be opened only by turning the handle.
3.2 Installation of pressure gauge: The threaded interface at the end of the compression nut shown in the figure is the installation part of the pressure gauge. Put a nylon gasket on the surface of the thread root and tighten the pressure gauge with a wrench.
3.3 Pressure detection, pressure gauges are installed on the front of the cylinder valve, which can display the pressure in the storage cylinder. When the pressure indicated value is lower than the green zone, it should be refilled.
3.4 When filling the fire extinguishing agent and driving gas, remove the pressure gauge, connect the end to the fire extinguishing agent hose, and loosen the compression nut to fill.
3.5 The cylinder valve is equipped with a safety diaphragm to prevent the pressure in the fire extinguishing agent cylinder group from being too high, and to release the pressure to protect the safety of the storage cylinder. Under normal circumstances, the safety diaphragm will not move. Only under abnormal conditions (such as high filling pressure and high ambient temperature), it may burst. After the safety diaphragm is activated and the pressure of the storage cylinder is released, the safety diaphragm should be replaced immediately, a tightness test should be carried out, and the fire extinguishing agent should be refilled.

 

Solenoid Valve (Actuating Cylinder Kit)

 

4.1 The cylinder valve is equipped with a safety pin (as shown in the figure above) to prevent the valve from malfunctioning due to collisions and vibrations during transportation, installation and commissioning, which may cause leakage or malfunction of the cylinder valve. After the installation is completed on site, the safety pin must be withdrawn before being put into use, otherwise the valve will not start and the system will fail.
4.2 A safety diaphragm (diaphragm burst pressure 9MPa) is installed on the cylinder valve to prevent excessive internal pressure from releasing pressure to protect the safety of the storage cylinder. The diaphragm should be replaced after the diaphragm moves and the pressure of the storage cylinder is released.
4.3 The cylinder valve has two opening modes: electric start and mechanical manual. For electric start, the controller sends out the valve opening command to make the electromagnetic actuating device act and open the cylinder valve; the mechanical manual is to manually remove the plug and press the button down to open the cylinder valve.
4.4 The cylinder valve is equipped with a pressure gauge to display the starting gas pressure in the cylinder. When the pressure indicated value is lower than the green zone, the starting gas should be refilled.

Relevant industry knowledge

 

What is FM200 fire suppression?
FM 200 is a clean agent fire suppressant that works by removing the heat from the fire triangle (oxygen, heat, and fuel). It is a colorless, odorless, and electrically non-conductive gas that leaves no residue to clean up. It is safe for use in occupied spaces and for the ozone layer.

 

What is the difference between FM200 and CO2?

CO2, a colourless and odourless fire suppression agent, falls into the category of gaseous fire suppression, offering a clean agent solution. On the other hand, FM200, also known as HFC-227ea, is a synthetic fire suppression agent known for its efficiency in rapidly extinguishing fires while leaving minimal residue.

What is the difference between FM200 and clean agent fire suppression system?

Unlike FM 200 systems, the agent is stored as a liquid and is converted into a gas when discharged. This clean agent is a replacement for halon and an alternative to hydrofluorocarbon extinguishing agents so it's not subject to the HFC phaseout.

 

Is FM200 gas harmful to humans?
Clean agent systems using FM-200™ are non-toxic to humans in levels used for extinguishing fires. When designing a fire suppression system, particular emphasis is placed on accurately calculating clean agent concentration levels to be safe in occupied spaces. Because it is clear, it will not obscure your vision.

 

Is FM200 a gas or foam?
FM200 is a non-flammable gas used for fire suppression. It doesn't damage electronic products, used correctly it's safe for people to breathe in and can be used in an enclosed space, making it ideal for colocation data centres.

 

Does fm200 leave a residue?

FM-200 is a clean agent fire suppressant for Class A, B, and C fires. It's a colorless, non-toxic gas that leaves no residue. For these reasons, it's an ideal solution for protecting high-value assets in areas that are occupied and in locations where the cleanup of other agents is problematic.
