The Intelligent Shutdown System consists of one or more accelerometers operating based on a voting mechanism. If more than half of the units vote for a shutdown, a shutdown alarm is triggered. Each node makes its decision according to the SI algorithm. Sensor outputs can be connected to relays at the client site or directly control a solenoid valve.

The system is primarily used in gas meters but can also be applied in dams and hydroelectric power plants. Additionally, it has applications in factories, gasoline pumps, pumping stations, oil companies, aviation organizations, metro systems, railways, and more.
