The cabinet heptafluoropropane fire extinguishing device is a portable and movable gas fire extinguishing device without pipe network. Its fire extinguishing system is well designed and reliable, and is extremely suitable for an area of less than 500m ²， Volume less than 1600m ³， And pipe network heptafluoropropane cannot be installed, which is difficult to maintain.
Usually, cabinet heptafluoropropane is composed of the following components: cabinet gas fire extinguishing device, fire detector, gas fire extinguishing alarm controller, etc., with automatic and manual control modes. The cabinet heptafluoropropane fire extinguishing device is composed of cabinet, storage bottle, bottle head valve, starting electromagnetic device, pressure annunciator, spray pipe, nozzle, etc.
In terms of appearance, the cabinet heptafluoropropane gas fire extinguishing device is composed of a fire cabinet and a fire extinguishing agent storage bottle. It has a beautiful appearance. It is usually placed in the protection area that needs to be protected. In case of a fire, it does not need to go through many pipelines to directly spray and extinguish the fire in the protection area.
The cabinet type heptafluoropropane fire extinguishing device is mainly applicable to key places such as computer rooms, libraries, archives, valuables warehouses, power stations, telecommunications centers, clean workshops, etc. Among them, the cabinet heptafluoropropane device does not need to set up a special bottle group room, and the whole cabinet is set up in the protection zone, which is suitable for the protection zone with small space such as the communication machine room. The combination of several cabinet devices can also protect the larger protection zone. This device can be used when it is impossible to set a special bottle group room in the building, or although there is a bottle group room, but the transportation distance is too far to meet the engineering design requirements, or it is inconvenient to install the system pipe network in the protection area.
The cabinet heptafluoropropane fire extinguishing device can be divided into five models according to the size and volume of the storage bottle: 70/90/120/150/180. From 70 to 180, there are five models in total. When selecting, select the appropriate model according to the size of the protection area and the design concentration.
The automatic procedure of cabinet heptafluoropropane fire extinguishing device is high, and it must be operated by specialized personnel who have been trained and are skilled in its performance. Any irrelevant personnel are forbidden to use this fire extinguishing system.
There are two operation modes: automatic control and manual control.
Auto-Control:
Under normal conditions, the control mode of the gas fire extinguishing controller is in the automatic position, and the fire extinguishing system is in the automatic control state. When a fire occurs in the protection area, the fire detector sends a fire alarm signal, and the fire alarm controller (or gas fire extinguishing controller) sends an audible and visual alarm signal. At the same time, it sends a linkage command to turn off the ventilation equipment such as air conditioners, fans and fire rolling shutters. After a 30 second delay (the staff in the protection area must evacuate quickly), the fire extinguishing power signal will drive the bottle electromagnetic starter, The released control gas opens the release valve in the corresponding area, and then opens the container valve on the extinguishing agent storage bottle to release the extinguishing agent to extinguish the fire.
manual control
When someone is working or on duty in the protection area, the control mode is "manual" position, and the fire extinguishing system is in manual control state. If a fire occurs in a protected area, press the start button on the panel of the fire alarm and fire extinguishing controller (or gas fire extinguishing controller), and then the fire extinguishing system can be started according to the automatic program to extinguish the fire. You can also press the "emergency start" button set at the door of the area after confirming the personnel and all evacuations, and then immediately press the "automatic" program to start and release the extinguishing agent to extinguish the fire.
In case of fire alarm, if it is found that it is not necessary to start the fire extinguishing system to extinguish the fire within the time delay, press the gas fire extinguishing controller or the "emergency stop" button outside the protective area to terminate the fire extinguishing procedure.
