Intercom Systems

What are Intercom Systems?

An intercom (intercommunication device), talkback or doorphone is a stand-alone electronic communications system intended for limited or private dialogue. Intercoms can be portable but are generally mounted permanently in buildings and vehicles. Intercoms can incorporate connections to walkie talkies, telephones, cell phones and to other intercom systems over phone or data lines and switch electronic or electro-mechanical devices such as signal lights and door latches.

Basic intercom system terms

Master Station or Base Station

These are units that can control the system, i.e., initiate a call with any of the stations and make announcements over the whole system.

Sub-station

Units that are capable of only initiating a call with a Master Station but not capable of initiating calls with any other stations (sometimes called slave units).
