Working principle of IG541 gas fire extinguishing system
This system has three starting modes: automatic start mode, manual start mode and mechanical emergency operation start mode.
Automatic start mode
The gas fire extinguishing alarm control system is generally equipped with two different types of fire detectors. There are "automatic" and "manual" manual conversion switches on the control host (the conversion switch can also be separated from the host and set outside the protection zone). When it is placed in the "automatic" position, the fire extinguishing system is in automatic state.
When only one detector sends a fire signal, the control host starts the alarm or sound and light alarm to notify the fire, but does not start the fire extinguishing system.
When two detectors send a fire signal, the control host starts the alarm and sound and light alarm, closes the opening of the protection zone, enters the fire extinguishing start delay, and automatically starts the fire extinguishing system after the set delay time is reached.
If it is found that the fire extinguishing system does not need to be started during the spraying delay process, the "emergency stop" button outside the protection zone or on the controller can be pressed to terminate the fire extinguishing command.
Manual start mode
When the switch is in the "manual" position, the fire extinguishing device is in manual state.
In this state, the detector sends a fire signal, and the control host starts the alarm and sound and light alarm to notify the fire, but does not start the fire extinguishing system. At this time, press the "manual start" or "emergency start" button outside the protection zone or on the controller to start the fire extinguishing system.
Note: Whether the controller is in automatic or manual state, pressing the "emergency start" and "manual start" buttons can start the fire extinguishing system.
Mechanical emergency operation start mode
When both automatic and manual starts fail, mechanical emergency operations can be implemented according to the following steps:
1) Manually close the linkage equipment and cut off the power supply;
2) Pull out the "mechanical emergency start safety pin" on the electromagnetic driver of the start bottle of the corresponding protection zone, press the mechanical emergency start button, and the electromagnetic driver opens the start bottle to release the start gas and start the fire extinguishing system.
