Which fire detection system is actuated by sensing a heat rise in a compartment?

🔍 Key Concepts

• Difference between manual and automatic fire detection systems • What a heat-actuated detector senses compared to a smoke detector • The role of a watchman’s supervisory system on board ships

💭 Think About

• Ask yourself: which system starts the alarm on its own when the temperature in a space rises, without anyone pressing or operating anything? • Which option describes a system that is triggered by heat specifically, not by visible particles or a person’s action? • What does a watchman actually do in a supervisory system—does it rely on human rounds, or on temperature sensors in the space?

✅ Before You Answer

• Identify which option clearly states it requires human action to trigger (this cannot be the heat-sensing system). • Identify which option is designed primarily to detect smoke particles rather than temperature rise. • Decide which remaining option(s) would start an alarm automatically upon detecting a rise in heat in the compartment.
