TELEPHONE - WALL
House telephone
BC 3013
This instrument is outwardly similar to BC 3030 but has no signalling arrangement. It is used in telephone installations connected to bell annunciators. An installation of this kind consists of an annunciator RP 130, a bell RA 510/4.5 or RA 610/4.5 and a battery. When calling, the button of the instrument is pressed, the corresponding indicator in the board being released at the same time as the bell rings. The conversation may then take place when the handset of the instrument mounted near the annunciator has been lifted. The same type of instrument is used for all instruments in the installation.
