🔍 Key Concepts

• Shipboard communications systems and how they get their power • Which systems are designed to work without ship’s main or emergency electrical power • Typical use and construction of sound-powered telephones on ships

💭 Think About

• For each option, ask yourself: does this system need the ship’s electrical distribution to function, or can it work purely mechanically? • Think about which system is specifically required for use during casualties, fires, and power failures to talk between key stations on the ship. • Consider how voice energy or sound might be converted directly into a signal without needing an outside power source.

✅ Before You Answer

• Identify which systems are clearly electrically powered (ship’s service, emergency, call-bell). • Recall which communications device is often used on bridge–engine room and emergency control stations because it does not depend on ship’s power. • Verify which system is described in training materials as working by the user’s voice energy rather than supplied electrical power.
