Fire Extinguishing Device for Detection Tube
Operation Principle: Upon detection of a fire in the protected area by the fire detector, the fire alarm controller confirms the fire and issues commands to activate the cabinet-type fire extinguishing unit. The central nitrogen cylinder of the extinguishing unit fills the extinguishing agent storage tank with pressurized nitrogen. When the pressure in the extinguishing agent storage tank reaches the working pressure, the tank valve automatically opens to release the extinguishing agent for fire suppression.
