Indirect System

An indirect suppression solution in which the heat-sensitive detection line and the nozzle from which the suppressing agent is discharged are separated from each other. The line is triggered at the point where it detects a temperature increase; the agent is distributed throughout the protected space via nozzles or piping rather than to a single point. Since it operates without requiring electrical power supply, it is preferred in large electrical panels, server cabinets, and telecommunications rooms.
