Up to a maximum of 30 stations, a telephone intercommunication system is ideal for offices, factories, hospitals, institutions, mansions, halls, etc., etc. It is, in fact, an automatic system, without expensive electrical and mechanical switching devices.
The simple operation of taking up the micro-telephone and pressing a selected button fully, signals the required station. On release the button is retained in the speaking position and automatically restored by replacing the micro-telephone, or by pressing another button should conversation be desired with any other station. The called station has only to take up the micro-telephone to reply.

Although this system is not secret, a disengaged station is indicated, when being rung, by a buzzer tone in the receiver: if no buzz is heard the station is engaged.

These instruments are the highest grade of telephone manufacture, which is necessary for intercommunication systems in order to obtain reliability, high transmission efficiency and low maintenance costs.
The push button and switch mechanisms are mounted on a metal plate, which ensures perfect alignment of the moving parts.
The micro-telephone is fitted with an electromagnetic receiver which, together with the inset transmitter, gives a high speaking efficiency and a very appreciable reduction in annoying side tone. The transmitter is fitted with an all-metal patent hygienic mouthpiece, so that the maintenance costs on all parts liable to rough usage are reduced to a minimum.
The casework is of high-class polished hardwood, and the exposed external fittings are finished in a durable and pleasing manner.

A diagram showing the method of connecting up the instruments, cables and batteries is supplied.
