Battery Ringing Wall Telephones

n1130.jpg (8087 bytes)Suitable for works, offices, shops, hotels, mansions, etc.

The framework and fittings are made and finished in the same superior manner as our other products for large installations.

These sets are equally suitable for single line and earth, or metallic circuits.

Three cells, joined in series, fitted at each station, are generally sufficient for supplying operating current, and three wires between each telephone and set of cells.  One wire is connected to the "zinc" end of the battery, the second wire to the carbon terminal of the middle cell for speaking current and the third wire to the carbon terminal of the third cell for signalling current.

For very long lines, an additional cell would be required for the signalling circuit. The third wire would then be connected to the carbon terminal of this cell.
