🔍 Key Concepts

• Difference between fixed temperature and rate-of-rise heat detectors • What makes a detector a line-type pneumatic device versus a spot (local) detector • How combined fixed temperature and rate-of-rise detectors are constructed internally

💭 Think About

• Look closely at parts D and E in the illustration: do they look like a small local element that would fail/melt at one temperature, or like a pressure-sensing bulb connected to a longer tube? • Notice the air passages labeled A and B at the top: what do they suggest about how air or gas pressure changes are sensed inside this device? • Ask yourself whether this component appears to respond only when a specific temperature is reached, or if it can also sense how fast the temperature (and pressure) is changing.

✅ Before You Answer

• Identify whether the sensing element is continuous along a length of tubing (line-type) or concentrated in one housing (spot-type). • Decide if there is any feature that would cause operation at a predetermined temperature, separate from sensing the rate-of-rise of temperature. • Confirm from the diagram whether the device seems to depend on gas expansion and pressure change (pneumatic principle) rather than a simple fusible link or bimetal element.
