🔍 Key Concepts

• Difference between fire detection (sensing flame) and fire extinguishing/ shutdown (stopping the turbine and releasing CO2). • How the GTM fire emergency shutdown switch is intended to be used by personnel at the module. • What events will automatically trigger the CO2 system and whether that also commands a turbine emergency stop.

💭 Think About

• Look at the illustration and think about which components are part of the detection system versus which are part of the emergency shutdown/ extinguishing system. • Ask yourself: does a UV flame detector by itself always force a full emergency stop, or can it first give an alarm or initiate a different sequence? • Consider whether the design allows more than one independent way to initiate an emergency stop, and whether all listed items would reasonably be tied into the same circuit.

✅ Before You Answer

• Verify which device(s) are labeled or described as initiating GTM fire emergency stop, not just alarm. • Check whether activation of the CO2 system is interlocked with automatic shutdown of the turbine. • Confirm if the UV flame detector alone is wired to a shutdown circuit or only to a fire alarm circuit.
