1. System introduction
Mixed gas IG-541 is made up of 52% 40% 40% nitrogen, argon, carbon dioxide mixture of proportion by the steric (physical) way, in a short period of time after discharge to the protection zone can make protection zone of the oxygen concentration is reduced to support combustion under 12.5%, and burning fire smothering action implementation., on the other hand, according to the long-term medical experiments prove that the human body in 12.5% oxygen concentration and the concentration of 2% to 5% carbon dioxide environment breath, brain of oxygen and at normal atmospheric environment (21% oxygen concentration and co2 concentration 0.03%) gained by the oxygen content is the same. This is because in hypoxia environment, if carbon dioxide concentrations increased to 2% 5% can make people breathing deepen and accelerate, in unit time make the person obtains enough oxygen to brain cells. Mixed gas IG - 541, 8% of the carbon dioxide gas is artificially make the protection zone of rising carbon dioxide levels to meet the anoxic environment breathing for 2% 5%, and won't cause harm to human body.unit independent system PART OF THE SYSTEM

3.System operation principle
1. mixed gas IG541 automatic fire extinguishing system with automatic, manual, mechanical emergency operation three kinds of start ways.
2.condition automatically, if a protection zone occurs with smoke (or temperature), the protection zone, smoke fire detector (or temperature) movement and the fire alarm controller into a single fire alarm, fire alarm
controller that is into the single state, drive electric alarm signal of a single fire alarm at the same time, this time will not start the fire extinguishing system of control signals. As the spread of fire protection zone,
the temperature rising smoke (or increase), the other primary circuit heat or smoke fire detector, the controller into a single fire signal, the controller immediately confirm that there is a fire, at the same time signal
composite fire alarm and linkage (closed air conditioning, ventilation device and fire damper, fire doors,
fire shutter, etc.). After 30 seconds of time delay, tThe controller output signal to start the fire extinguishing system, cast into the fire extinguishing agent through the pipeline to implement fire protection zone. Controller
receives the feedback signal of pressure signal after the show bright deflated lights, avoid straying. In manual mode, alarm controller only when the fire broke out a fire alarm signals and does not produce linkage.
3. requires automatic or manual mode, the personnel on duty after confirmation of fire, press the alarm controller on the front panel or the scene of the "emergency start" button to start the fire extinguishing
system immediately. Before discharge control signal output, press the alarm controller on the front panel or the scene of the "emergency stop" button, the system will not discharge signal output.
