INTERCOMMUNICATION TELEPHONES 


Since the publication of our eighth edition Telephone Catalogue, the use of Intercommunication Telephones has become almost universal, particularly for installations which do not number more than twenty-five or thirty stations. The General” System - which may be termed the pioneer of Intercommunication Systems - is still one of the most successful that has ever been offered, and forms a standard of efficiency which has caused it to be the subject of many imitations. Thanks to the increased demand we are enabled to reduce the prices to an appreciable extent, without in any way affecting the quality of the work.’

The same remarks also apply to the “Handcom” Intercommunication System, the distinguishing feature of which is the inclusion of the switch in the handle of the Hand Combination. The illustrations show clearly the adaptability of these’ instruments to various positions, an advantage which has greatly added to the success of this type of instrument.

More recently we have introduced the “Combat” Intercommunication System, which permits of the use of a Common Battery throughout. This system, however, is only advised for installations up to ten stations, as a larger installation would be of sufficient merit to demand instruments of greater efficiency.

The most up-to-date Intercommunication System, however, is undoubtedly our “S.R.” Self-replacing System, which possesses several advantages over those of any other system previously offered.

This instrument consists of:

  • Micro Telephone.

  • Induction Coil.

  • Call Buzzer.

  • Special Push Button Line Selectors.

  • Automatic Switch Hook.

The Micro Telephone consists of a ring magnet double-pole receiver, combined with a “Hunningscone-Deckert” Transmitter, and mounted on ebonite handle. In the handle a switch is provided, which, when pressed, disconnects the buzzer, closes, the battery circuit, and connects the telephone to the line previously selected. When the hand switch is released it automatically leaves the buzzer connected to the home line for receiving a call. The induction coil is made to Post Office specification.

The Push Button Line Selector is arranged so that the selection of a line is accomplished by depressing the button corresponding to the number of the station required. This button when depressed connects the battery to the line, and slightly regains its position when the pressure is removed. When the conversation is finished, and the telephone replaced on the automatic switch. the button regains its normal position.

When a call is received all that has to be done is simply to take up the telephone and reply in the ordinary manner. If any one Push Button has been operated, and a second one is pressed in, the first regains its normal position immediately The terminals are quite hidden and cannot be tampered with, although the wiring can be done from the front of the instrument after it has been screwed up. The terminals are concealed by a panel moulding, placed round the line selector push button as shown by the illustrations.

The function of the automatic switch is two fold.

First: To disconnect the ringing battery when the telephone is hung up, so that should mischievous persons depress any of the ringing ‘keys ‘without having first lifted the telephone, the battery is not connected, and does not give a call unnecessarily.

Second: By engaging the movement of the line selector, thus causing the push button, which has been operated, to regain. its normal position.

The instrument is fitted with solid walnut case, well polished and highly finished.
