When the alarm controller 3 is in a manual state, the alarm controller 3 only sends out an alarm signal, does not output an action signal, and after a person on duty confirms a fire alarm, the person on duty presses an emergency start button or a protection zone door on the alarm control panel, and an emergency start-stop button at the mouth can start the perfluorinated hexanone fire extinguishing device 4.
When no person is in the protection area of the energy storage container, the control mode in the gas fire extinguishing controller 3 is switched to the automatic position, the fire extinguishing system is in an automatic control state, after a smoke detector in the protection area reports a fire alarm, a host computer sends an alarm and sends a signal to the gas fire extinguishing controller 3, and the gas fire extinguishing controller 3 starts all sound and light in the gas fire extinguishing area through a linkage program to remind workers; when the detector reports a fire, the gas fire extinguishing controller 3 starts to enter a delay stage and sends out a linkage instruction at the same time, all power supplies except emergency illumination in the linkage equipment and the protection area are closed, the audible and visual alarm 7 is started, and after the automatic delay is carried out for 30 seconds, a fire extinguishing instruction is sent out to a starting bottle controlling the fire area; and opening the starting bottle, then opening the corresponding selection valve and the fire extinguishing agent storage bottle by starting gas in the bottle, and performing fire extinguishing operation on the fire area.
In the method provided by the invention, when a person works or is on duty in the protection area of the energy storage container, the control mode change-over switch in the controller 3 is shifted to a manual position, and the system is in a manual control state. When a fire occurs, the fire extinguishing system can be started by manually pressing a manual starting button or starting an emergency starting button arranged outside a protective area door of the energy storage container according to the program, so as to extinguish the fire. In an automatic control state, the electric manual control can be still realized, and personnel in the protection area can be completely evacuated before the electric manual control is implemented.
When the fire alarm occurs, and the situation that the fire extinguishing system is not required to be started for extinguishing is found in the delay time, an emergency stop button on the controller 3 or in the manual control box is pressed, so that the fire extinguishing instruction is prevented from being sent out, and the fire extinguishing program of the system is stopped.
Illustratively, a mechanical emergency manual control may also be provided in the method of the present invention: when fire occurs in the protection area, but the fire extinguishing agent can be released to extinguish fire due to the fact that the power supply fails or the automatic control system and the control system fail and can not execute the fire extinguishing instruction, the selection valve of the gas storage bottle of the corresponding protection area is directly opened manually. When the mechanical emergency is controlled manually, the equipment affecting the fire extinguishing effect must be closed in advance, and the personnel in the protection area can be informed and confirmed to be evacuated to the rear.
When the fire alarm occurs and the condition that the fire extinguishing system is not required to be started for extinguishing is found in the delay time, an emergency stop button on the JBF5014 gas fire extinguishing controller 3 or in the manual control box can be pressed, so that the fire extinguishing instruction can be prevented from being sent out, and the fire extinguishing program of the system is stopped.
