Fire Detection Cable

The fire detection cable comprises two metallic strips, separated by a small air gap. The condition of the metallic strips is constantly monitored by the fire suppression control module. If a fire develops in the engine compartment and the temperature exceeds 180°C, the metallic strips start to melt and come into contact with each other. Sensing this, the control module introduces the Aqueous Film Forming Foam into the engine compartment via the fire suppression nozzles.
