Entryphone Amplifier board (including microphone)

The 11ETXAMP speech unit replaces the audio speaker unit and will require a fourth core between the PSU and the door panel to supply a separate positive line to the speech unit.

This speaker unit has been designed to work with the Videx V-380 telephone interface as well as the BPT and Bell Systems versions (I cannot recall what model numbers of these products however). It will allow one of the flats to communicate with a visitor via their landline telephone system without affecting the performance of the neighbouring flats door entry telephones.
