🔍 Key Concepts

• Engine Order Telegraph (EOT) normal vs. abnormal ringing – when does the bell give a short ring, and when does it keep ringing? • Current Failure Alarm Panel vs. Constant Ringing and Trouble Alarm Relay Panel – note they are two separate alarm functions on the diagram. • How the acknowledge handle / indicator arrow correspondence is shown in the control‑room EOT and what contacts change when they do NOT match.

💭 Think About

• On the diagram, start at the "Constant Ringing and Trouble Alarm Relay Panel" and trace its wiring to see what devices or contacts actually control that relay. Does it go to a power supply, to position switches, or to a current failure circuit? • Compare that to the "Current Failure Alarm Panel" wiring. Which alarm (buzzer/light) is tied to the loss of power source, and which is tied to order‑mismatch or abnormal telegraph operation? • Look closely at the contacts labeled for wrong direction, non‑correspondence, or acknowledge circuits around the control‑room EOT. Which condition would logically require a continuous alarm until corrected?

✅ Before You Answer

• Identify which alarm circuit is clearly labeled for current or power failure and which is labeled constant ringing and trouble – they are not the same. • Verify whether the constant ringing relay coil gets its signal from power‑supply lines or from EOT position / acknowledge contacts. • Confirm which option talks about loss of main AC power versus loss of battery/emergency power and which one refers to mismatch between order and acknowledgement. Match that to what you see feeding the constant‑ringing relay.
