Q: What is a large space intelligent fire extinguishing device?

Answer: The large space intelligent fire extinguishing device includes a large space automatic scanning and positioning sprinkler device and an automatic sprinkler system. The large space automatic scanning and positioning water-spraying fire extinguishing device is a fire-extinguishing product that combines automatic and water-spraying fire extinguishing. The fire-extinguishing product includes a ceiling type, a middle suspension type (gun), a quick-spray automatic scanning and positioning water-spraying fire extinguishing device, and an automatic water-spouting fire-extinguishing device. It is a centrifugal sprinkler device consisting of a centrifugal sprinkler and an external sensor.

Various devices (guns) are the control center of the automatic scanning and positioning sprinkler system. Each automatic scanning and positioning sprinkler device (gun) is a single working unit. The microprocessor is integrated inside and the flame is completed separately. Signal acquisition, processing, analysis, control of its own, to complete the judgment of the flame.

Q: What is the process of automatic scanning and positioning of sprinkler devices (guns)?

Answer: After power-on reset, the device (gun) is in the state. The information collected by the sensor through the fire, when the domain value is reached, the drive mechanism is automatically activated to carry out a horizontal scan. After confirmation, a vertical scan is performed. After the confirmation, the fire point is aligned to carry out coordinate positioning, the solenoid valve is activated, and a fire alarm signal is issued. Start the linkage equipment to spray fire water in the form of a full water column. After the fire is extinguished, the solenoid valve is automatically closed and the water spray is stopped. After another week of searching, if there is still a fire, fire sprinkler can be fired repeatedly. Confirm that there is no fire recovery monitoring status.

Q: How does the automatic sprinkler system work?

Answer: After power-on reset, the device is in monitoring state. The sensor collects the information of the fire, uses a combination of ultraviolet sensors to confirm the fire, activates the solenoid valve, sends a fire alarm signal, and starts the linkage equipment. The large water droplets form a uniform water spray on the protection space. Large rain can effectively pass through the hot gas flow to effectively extinguish the fire. . After the fire is extinguished, the solenoid valve is automatically closed and the water spray is stopped. After the automatic confirmation of no fire, the monitoring status is restored. If there is still a fire, fire sprinklers can be fired repeatedly.

Q: What are the main features of large space intelligent fire extinguishing devices?

A: Real-time action: All kinds of products collect flame information through various sensors in real time, and can monitor the situation in the protection area in real time. The time from device startup to positioning confirmation of fire is less than 20 seconds. It can effectively detect the initial fire.

Effective Fire Extinguishing: Automatic Scanning and Positioning The water spray of sprinkler devices (guns) is filled with water. All of them cover the fire point. The water column has a strong penetrating ability and thus has the ability to quickly extinguish the fire. In the process of extinguishing fire, the medium-suspended fire extinguishing device can also simulate the artificial fire extinguishing process. It not only swings up and down, but also oscillates to the left and right. The rapid fire extinguishing can effectively prevent the spread of fire. The water spray of the automatic sprinkler device is a uniform large raindrop, and evenly sprinkles water in the protection space. The large raindrops can effectively pass through the hot gas flow and can achieve the purpose of rapid fire extinguishing.

Reliability: The process of self-scanning and positioning sprinkler devices (guns) to determine the flame is completed after multiple compound judgments. From infrared signal and ultraviolet signal acquisition to analysis and confirmation of the flame, the flame signal is achieved through logical AND. The composite judgment effectively prevents the malfunction of the automatic fire extinguishing device.

Self-inspection function: The automatic scanning and positioning water-spraying fire extinguishing device (gun) has a microprocessor inside, and it can complete the judgment of its working status through self-checking. Ensure that the automatic scanning positioning sprinkler device (gun) works properly.

Full-space protection: automatic scanning and positioning water-spraying fire extinguishing devices (guns) product detection, fire extinguishing in one, can monitor and protect the entire 360-degree, 180-degree vertical space within the protection radius, a little fire, can achieve up to four products At the same time fire sprinkler fire at the point of fire, can form a little fire, surrounded by siege situation.

In addition to the above characteristics, the product also has the characteristics of detection and fire extinguishing, which has the characteristics of timely detection, accurate positioning, rapid fire extinguishing, strong fire extinguishing ability, repeatable fire extinguishing and large space protection, and can effectively eliminate the initial state of fire.
