Dual-cabinet Halon 1301 fire extinguishing system
Operating Principle: When a fire detector detects a fire in the protected area, the fire alarm controller confirms the fire and sends commands to activate the cabinet-type fire extinguishing unit. The central nitrogen cylinder of the extinguishing unit fills the lead storage tank of the extinguishing agent with pressurized nitrogen. Once the pressure in the lead storage tank of the extinguishing agent reaches the working pressure, the valve of the extinguishing agent tank automatically opens to release the extinguishing agent for fire suppression.
