🔍 Key Concepts

• Radiotelegraph auto-alarm system on compulsorily equipped ships • Difference between a distress signal (SOS / Mayday) and the special auto-alarm signal • What a "keying device" does in radio operation

💭 Think About

• Is the auto-alarm signal the same as an SOS, or is it a special pattern whose purpose is to trigger receivers on other ships and coast stations? • Does a keying device have more to do with forming the correct signal pattern, or deciding what message (like SOS) is sent? • Think about why automation is useful in an alarm system that must be recognized reliably worldwide.

✅ Before You Answer

• Review how the auto-alarm signal was defined in traditional radiotelegraph service (its specific purpose, not its content in Morse letters). • Check whether an auto-alarm system needs a signal that is standardized and precisely timed, and how a keying device helps achieve that. • Confirm whether SOS itself needs a special device, or if the keying is mainly to generate the characteristic auto-alarm pattern that sets off alarms on other ships.
