The Concorde is fitted with a Graviner Firewire Triple FD continuous element system for fire detection, and a discreet sensing element system for engine bay overheat detection. To comply with airworthiness requirements, these detection systems have been augmented by a Graviner optical system that uses the ultraviolet radiation emitted by a fire to detect engine combustion chamber flame burn-through, The Graviner Firewire Triple FD System relies on both resistive and capacitive electronic functions for its operation, thereby discriminating between true and false warnings caused by short circuits etc. Each of the four engines on the Concorde is protected by a Graviner type 208A dual-head automatic extinguisher supplying a spray nozzle system. The extinguishing systems of each adjacent pair of engines are interconnected using directional flow valves, thereby providing each engine bay with a "two shot" extinguishing capability.
