Hanging Ultrafine

Product Details
I. Fire Extinguishing Principle
1. Temperature control: When the ambient temperature rises to a nominal value, the valve on the fire extinguishing device opens automatically and releases ultra-fine dry powder fire extinguishing agent.
2. Thermal initiation: In a specific environment, when the fire extinguishing device needs to be started quickly, the fire signal is quickly transmitted to the fire extinguishing device through the heat sensitive line, and the fire extinguishing device starts to release ultra-fine dry powder fire extinguishing agent.
3. Electronic control: The electronic control fire extinguishing device can connect with all fire alarm controllers, output feedback signals when spraying, detect composite fire signals by detectors and send them to fire alarm controllers. The controller confirms and outputs command signals (command signals are divided into passive switch signals and active energy signals). The command signals are activated by repeaters. The dynamic fire power supply opens the valve to the fire extinguishing device and releases the ultra-fine dry powder fire extinguishing agent to extinguish the fire.
 
II. Main Advantages
1. Effectiveness of fire extinguishing
It can realize passive spontaneous start-up, extinguish the fire in the early stage of ignition, realize early suppression and reduce losses.
2. Simple system and low cost
Ultra-fine dry powder automatic fire extinguishing device does not need to set up special storage bottles, occupies a small area, does not need power supply and complex electronic control equipment and pipelines, does not need special smoke and temperature sensors, avoids the possibility of misoperation, system construction is simple, high reliability, saves building area, and greatly reduces the cost of construction.
3. Small dosage of fire extinguishing agent and low cost of fire extinguishing
The traditional fixed gas fire extinguishing system takes the room with large enclosed space as the protective area, while the ultra-fine dry powder automatic fire extinguishing device only determines the amount of fire extinguishing agent according to the area or volume calculated by the protective object, which greatly reduces the amount of fire extinguishing agent and reduces the cost of a fire extinguishing.
