Explosion-proof electric control fire cannons are mainly composed of explosion-proof fire extinguishing devices, explosion-proof field control panels, explosion-proof wireless remote controllers, etc. They can remotely control the horizontal and vertical rotation of the fire cannon, accurately controlling the water jet. The water jet can be a water column or water mist to meet different fire extinguishing needs. The system adopts an explosion-proof structural design that meets national standards. It is suitable for heavy fire trucks, fireboats, industrial and mining enterprises, warehouses, oil fields, fixed fire extinguishing equipment for storage tanks, etc.
The PLKAEX series fixed electric control fire foam monitor features a large flow rate and long range, enabling remote wired/wireless control and local manual control. The motor and junction box are explosion-proof, and the electrical control cabinet can be placed in the control room for remote operation and positioning, facilitating the safe evacuation of firefighters from the fire scene and ensuring safe and effective fire extinguishing. Suitable for various oil, gas, and dust hazardous explosion sites.
The ZSFZ wet alarm valve is a one-way valve that only allows water to flow into the sprinkler fire suppression system in one direction, and drives the associated components to alarm under specified pressure and flow rate. It forms a widely used wet automatic sprinkler fire suppression system together with a water flow indicator, a signal valve, a pressure switch, a sprinkler head, etc. This system is in standby operation for a long time, with the pipe network filled with pressurized water. When a fire occurs in the protected area, the ambient temperature rises, causing the temperature-sensitive element on the sprinkler head to activate, the sealing component falls off, and the system automatically starts, spraying water directly to the fire area and issuing an alarm signal to achieve the purpose of alarm, fire extinguishing, and fire control.

A pre-action device consists of a pre-action alarm valve group, a control panel, a pressure maintaining device, and an air supply device. It is a one-way valve group device that allows water to flow into the sprinkler system in one direction while simultaneously sounding an alarm through electric, pneumatic, mechanical, or other methods. A pre-action device, together with closed sprinklers, inflation equipment, water supply facilities, and pipes, constitutes a pre-action system. In the standby state, the water distribution pipes are not filled with water. Depending on the application of the pre-action system, there are two automatic control methods for the pre-action device: one is activated only by a signal from the fire alarm system, and the other is activated by signals from both the fire alarm system and a pressure switch installed on the inflation pipe.
The ZSFY pre-action device is an automatic sprinkler fire extinguishing device developed in recent years. It combines fire automatic detection and alarm technology with an automatic sprinkler fire extinguishing system, providing dual protection for the protected object. It is especially suitable for important places that are prone to freezing or where water damage is unacceptable, such as computer rooms, generator rooms, data rooms, historical archives, and high-rack warehouses. Before a fire occurs, the system's side pipeline is filled with compressed air, so the system has the characteristics of a dry system and can meet the needs of automatic sprinkler irrigation under high-temperature and freezing conditions.
