🔍 Key Concepts

• How mechanical thermostats work in basic home or machinery applications • Difference between heat detectors vs. smoke detectors in fire alarm systems • Typical sensing element used in rate-of-rise or fixed-temperature heat detectors

💭 Think About

• Look at which options involve sensing heat directly rather than smoke or light obstruction. • Ask yourself: a thermostat is usually triggered by temperature change—which choice fits that idea best? • Consider where you’ve seen simple thermostats (like in irons, ovens, or older heaters). What physical principle do they commonly use to switch on or off?

✅ Before You Answer

• Verify which options are actually smoke detection methods rather than heat/temperature detection. • Identify the choice that uses expansion due to temperature change as the triggering mechanism. • Confirm that a thermostat is not normally based on changes in air pressure or an electric eye/beam.
