Which term describes the sequence of control system functions for establishing a source of ignition that must be complete and verified immediately before firing the flame effect?

• A. Arm
• B. Ignition readiness sequence
• C. Ignition sequence
• D. Pre-fire check

Answer: (C)

The ignition sequence is the defined set of control actions that brings an ignition source online and must be completed and verified before firing the flame effect. It encompasses initiating the ignition hardware, ensuring fuel and ignition sources are available, activating any purge or safety interlocks, and confirming sensors are in a safe, ready state. This makes it the best term, because it names the full series of steps needed to establish ignition, not just a single readiness moment or a pre-fire verification. Arming is only about putting the system in a ready-to-fire state, not executing the full sequence; a pre-fire check is the final verification performed just before firing, not the complete sequence of establishing ignition. Ignition readiness sequence might be used in some contexts, but ignition sequence is the standard term for the complete set of actions to establish ignition.
