FIELD: fire powers.

SUBSTANCE: fire suppression system contains the first fire suppression unit containing the first cylinder comprising the first suppressant and the second fire suppression unit containing the second cylinder comprising the second suppressant substance and each fire suppression unit is implemented with a possibility of use of pressure difference between the respective cylindrical internal part and environment for distribution of the respective suppressant. The first cylinder is under pressure higher, than ambient one, the first fire suppression unit generates a signal when the first suppressant is released from the first cylinder, and the second fire suppression unit is implemented with a possibility of response to a signal. The connecting element is provisioned which interconnects the first fire suppression unit with the second fire suppression unit, and the connecting element is implemented with a possibility of signal transmission from the first fire suppression unit to the second fire suppression unit.
