S-shaped suspended thermal smoke extinguishing device

Operation Principle: Upon detection of a fire in the protected area by the fire detector, the fire alarm controller confirms the fire and issues a command 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. Once 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.
