I. Tr*ning device for gas fire extinguishing system Overview:
1. Basic principles and fire extinguishing methods:
According to the requirements of the specification, the system adopts two types of composition: a fully flooded unit independent system and a combined distribution system. The unit independent system is a form in which a set of fire extinguishing agent storage device corresponds to a set of pipe network system to protect a protection area. The combined system is a form in which a set of fire extinguishing agent storage device corresponds to several pipe network systems to protect two upper protection areas.
2. Tr*ning device for gas fire extinguishing system Composition:
Pipe network heptafluoropropane fire extinguishing device, pipe network, gas fire extinguishing controller, fire detector, sound and light alarm, gas discharge indicator light, emergency start and stop button, external power supply, etc. constitute a complete automatic fire extinguishing system.
II. Control mode:
This system m*nly has four control modes: automatic, manual, mechanical emergency manual and emergency start/stop.
(1) Automatic control mode: This fire extinguishing controller is equipped with a smoke fire detector and a fixed temperature heat fire detector. There is a control mode selection lock on the controller. When it is placed in the "automatic" position, the fire extinguishing controller is in the automatic control state. When only one detector sends out a fire signal, the controller will send out a fire alarm sound and light signal to notify that an abnormal situation has occurred, but will not start the fire extinguishing device to release the fire extinguishing agent. If it is necessary to start the fire extinguishing device to extinguish the fire, you can press the "emergency start button" to start the fire extinguishing device to release the fire extinguishing agent and implement fire extinguishing. When two detectors send out fire signals at the same time, the controller will send out fire sound and light signals to notify that a fire has occurred and that relevant personnel should evacuate the scene, and issue a linkage command to shut down linkage equipment such as fans and fire dampers. After a period of delay, it will issue a fire extinguishing command to open the solenoid valve, start the gas to open the cont*ner valve, release the fire extinguishing agent, and implement fire extinguishing. If it is found that the fire extinguishing device does not need to be started during the alarm process, you can press the "emergency stop button" outside the protection area or on the control operation panel to terminate the occurrence of the control fire extinguishing command, do not start the fire extinguishing device, release the fire extinguishing agent, and implement fire extinguishing.
(2) Manual control mode: When the control mode selection lock on the controller is placed in the "manual" position, the fire extinguishing controller is in manual control.
state. At this time, when the fire detector sends out a fire alarm signal, the controller will send out a fire sound and light alarm signal, but will not start the fire extinguishing device. After observation by personnel, when confirming that a fire has occurred, the "emergency start button" outside the protection zone or on the controller operation panel can be pressed to start the fire extinguishing device, release the fire extinguishing agent, and implement fire extinguishing. However, the alarm signal still exists.
Regardless of whether the device is in automatic or manual state, pressing any emergency start button can start the fire extinguishing device, release the fire extinguishing agent, and implement fire extinguishing. At the same time, the controller immediately enters the fire extinguishing alarm state.
(3) Emergency mechanical start working mode: used when the controller f*ls. When the on-duty personnel determine that it is a fire, they should immediately notify all personnel on the scene to evacuate the scene. After confirming that all personnel have evacuated the scene, the emergency mechanical start can be implemented according to the following steps: ① Manually close the linkage equipment and cut off the power supply. ② Open the corresponding protection zone selection valve. ③ Open the cont*ner valve on the corresponding protection zone storage bottle group in groups or one by one to immediately implement fire extinguishing.
(4) Emergency start/stop working mode: used in emergency situations. In the first case, when the on-duty personnel discovers a fire and the gas fire extinguishing controller does not send out an audible or visual alarm signal, they should immediately notify all personnel on site to evacuate the scene. Only after confirming that all personnel have evacuated the scene can they press the emergency start/stop button and the system will immediately implement the fire extinguishing operation; in the second case, when the gas fire extinguishing controller sends out an audible or visual alarm signal and is in the delay stage, if it is found that there is no fire alarm, the emergency start/stop button can be pressed immediately and the system will stop the fire extinguishing operation to avoid unnecessary losses.
