Q

CO₂ cylinders equipped with pressure actuated discharge heads will discharge automatically when __________.

🔍 Key Concepts

• CO₂ fixed fire extinguishing systems operation sequence • How pressure-actuated discharge heads are triggered • Difference between control (pilot) cylinders and main storage cylinders

💭 Think About

• Think about the exact moment the main CO₂ cylinders are supposed to open: is it at the start of the control action or after something is fully completed? • Which component actually senses pressure and causes the discharge heads on the storage cylinders to operate? • What is the functional purpose of the control (pilot) cylinders in relation to the main bank of CO₂ cylinders?

✅ Before You Answer

• Identify which part of the system has the pressure-actuated discharge heads: is it the control cylinders or the main storage cylinders? • Confirm the sequence of operations: manual release → pilot/control cylinder action → pressure signal → main cylinder discharge. • Make sure you are distinguishing between "initial detection of pressure" and a condition where a full pilot discharge has already occurred.
