The system realizes hand -automatic fire extinguishing, flexible arrangement of spray head, accurate temperature sensing starting, full use of fire extinguishing agent, intelligent pressure monitoring and adaptation to low temperature environment, greatly improves the performance and reliability of the fire extinguishing system, and provides stronger guarantee for fire safety.
