SC211 is a simple robust intercom / talk-back station. It is mostly used in engine room and on deck. It comes as a basic body, and the installer must choose either a headset or a horn speaker for the station to be used.
When used with a headset, it implements communication in noisy areas as engine room, truster room or generator room. For such areas, it also has a build in relay for driving a flash / horn used to indicate when a call comes in. With a headset full duplex communication is obtained.
When used with a horn speaker, the station is operating in semi-duplex. It is required that the user press a key on the front when speaking into the horn - PTT mode - or the SC211 can be used as classical talk-back, where the call is entirely controlled from a master SC411 on the bridge. From bridge You can call the SC211 and speak out, and when the PTT button is released, listen back from out there.
