Cabinet-Type Heptafluoropropane Operation Guidelines

　　The cabinet-type heptafluoropropane fire suppression system is a lightweight, portable gas-based fire-fighting device that does not require installation of a piping network. Featuring an exquisitely designed fire suppression system and highly reliable performance, it is ideally suited for protected areas smaller than 500 m² in area and less than 1,600 m³ in volume—areas where conventional piped-heptafluoropropane systems cannot be installed due to space constraints or maintenance challenges.

　　Typically, cabinet-type heptafluoropropane systems consist of the following components: a cabinet-type gas fire suppression unit, along with fire detectors and a gas fire alarm control panel, offering both automatic and manual control modes. Specifically, the cabinet-type heptafluoropropane fire suppression unit comprises a cabinet body, storage cylinders, cylinder head valves, an initiating solenoid device, pressure sensors, discharge pipes, nozzles, and other essential parts.

　　Externally, the cabinet-type heptafluoropropane gas fire suppression system consists of a fire-resistant cabinet and a fire-suppressant storage cylinder, featuring a sleek and attractive design. Normally, it is placed within the protected area that requires safeguarding. In the event of a fire, it can directly release the extinguishing agent into the protected zone without the need for extensive piping systems.

　　The cabinet-type heptafluoropropane fire suppression system is primarily suitable for critical areas such as electronic computer rooms, libraries, archives, valuable goods storage facilities, power stations, telecommunications centers, and clean production workshops. Notably, the cabinet-type system eliminates the need for a dedicated cylinder room—instead, the entire cabinet is installed directly within the protected zone. This makes it ideal for smaller spaces like communication equipment rooms. Additionally, multiple cabinet units can be interconnected to effectively protect larger protected areas. This system is particularly beneficial when a dedicated cylinder room cannot be established within the building, or if, despite having a cylinder room, the delivery distance is too long to meet engineering design requirements. It’s also an excellent choice when installing a conventional piping network within the protected zone would be impractical or inconvenient.

　　Cabinet-type heptafluoropropane fire suppression systems are categorized by the storage cylinder's volume: 70/90/120/150/180. Within the 70 to 180 range, there are five models in total. When selecting a model, consider the size of the protected area and the design concentration to ensure the right fit.

　　The cabinet-type heptafluoropropane fire suppression system features a highly automated process and must be operated only by specially trained personnel who are thoroughly familiar with its performance. Unauthorized individuals are strictly prohibited from using this fire suppression system.

　　It is divided into two operation modes: automatic control and manual control.

　　Automatic Control:

　　Under normal conditions, the gas fire suppression controller is set to the automatic mode, placing the fire suppression system in fully automated operation. If a fire occurs within the protected area, the fire detectors will immediately send an alarm signal to the fire alarm control panel (or the gas fire suppression controller), which will activate both audible and visual alarms while simultaneously issuing interlock commands to shut down ventilation equipment such as air conditioners, fans, and fire-resistant rolling shutters. After a 30-second delay—during which personnel inside the protected area must evacuate promptly—the fire suppression power supply will energize the cylinder solenoid actuator, triggering the release of control gas that opens the corresponding zone's discharge valve. This, in turn, activates the container valve on the extinguishing agent storage cylinder, allowing the灭火剂 to be released and initiating the fire suppression process.

　　Manual control

　　When personnel are working or on duty in the protected area, select the "Manual" position for the control mode, placing the fire suppression system in manual control. If a fire occurs in a specific protected zone, simply press the start button on the fire alarm and suppression controller (or gas fire suppression controller) panel to activate the fire suppression system according to the automatic sequence, initiating灭火 operations. Alternatively, once it has been confirmed that all personnel have safely evacuated, pressing the "Emergency Start" button installed at the entrance of the zone will immediately trigger the system to switch to "Automatic" mode, releasing the extinguishing agent to suppress the fire.

　　When a fire alarm is triggered, if it’s determined within the delay period that the fire suppression system does not need to be activated, simply press the "Emergency Stop" button on the gas fire control panel or outside the protected zone door to terminate the extinguishing procedure.
