Single-cabinet Halon 1301 fire extinguishing system

Operation Principle: Upon detecting a fire in the protected area, the fire detector triggers the fire alarm controller, which confirms the fire and sends a command to activate the cabinet-type fire extinguishing unit. The central nitrogen cylinder of the extinguishing unit then fills the lead storage tank of the extinguishing agent with pressurized nitrogen. Once the pressure in the lead storage tank reaches the working pressure, the tank valve automatically opens to release the extinguishing agent for fire suppression.
