Intercommunications System

The intercommunications system, also known as intercommunication device or simply  intercom, is an electronic communications system that allows for dialogue between different areas of the ship, for example between the engine room and the bridge. Intercommunication systems, in maritime terms, are generally meant to facilitate brief or even private conversations such as those making announcements or giving directions or orders. Intercommunication devices can be portable (i.e. walkie talkies) or permanently mounted.
