Fire Detection Systems
Thermocouple system: Works on rate of temperature rise. Does not give warning when an engine slowly overheats.

Continuous - loop detector system In case of fire, the core resistance drops and current flows between the signal wires and the ground, energising the alarm system

Fire Extinguishing Systems
Types of extinguishing systems High Rate of Discharge (HRD) System: Provide high discharge rate through high pressurisation, short feed lines, large discharge valves and outlets. Extinguishing agent is released into the zone in one second or less. Conventional System System is designed around a cylinder that stores the CO2 under pressure and a remote control valve assembly in the cockpit to distribute the extinguishing agent to the engine.
