Abstract

The entry phone system comprises a loudspeaker (2) and microphone (3) unit and one or more sets (4) of call buttons (5) which are arranged together to form a compact unit (1). The loudspeaker unit (2) and the microphone unit (3) pref. have the same dimensions, each of them being rectangular, with the call buttons (5) also rectangular but of smaller size and arranged symmetrically to one or both sides of the loudspeaker and microphone units (2, 3). End elements inserted at either side of the set(s) of buttons (5) provide a button assembly of the same width as the superposed loudspeaker and microphone units (2, 3).
