ENGINE ROOM TELEGRAPHS

ScnMaster

mechanical devices, each with a dial and two indicators (one having a handle attached), located on the bridge and in the engine room. If the ship has two engines, there is a separate telegraph for each. The dial shows by subdivisions the various speeds which are sent below according to how the indicator is set. The engineer hearing an automatic bell notes by indicator the desired speed of the engines. As a check against error he similarly returns his signal to the bridge where it is recorded by the second indicator. Also referred to as bells and engine bells. —Welcome to the SO Glossary Final approval 2-Mar-90
