What is the primary function of the fire detection system in a gas turbine?

The primary function of the fire detection system in a gas turbine is to detect fire and alert personnel. This system plays a critical role in ensuring safety by monitoring for signs of combustion and providing early warnings to operators or maintenance teams. Once a fire is detected, it is crucial to alert staff so they can take appropriate action, which may include activating fire suppression systems, evacuating personnel, or shutting down equipment to prevent further escalation.

While other options mention actions that are part of fire safety protocols, such as extinguishing fires, cooling systems, or isolating fuel supplies, these are secondary responses that often rely on the initial detection of a fire. The detection system’s primary job is to identify heat or flames and communicate that information effectively to ensure a rapid response to mitigate danger.
