GEC K7915

IRON CASED AND WEATHERPROOF
TRADESMAN’S BATTERY CALL TELEPHONES
WITH INDUCTION COIL
SPECIALLY DESIGNED FOR FLATS

These telephones were specifically made for flat entrance use.  They are ironclad, watertight and have a flexible receiver arm.  Supplied with 5, 15, 21 or 30 lines according to requirements.

The Tradesman’s Battery Call “Service” Telephone is designed primarily for the convenience of occupiers of large modern blocks of fiats, who frequently suffer annoyance from tradesmen’s representatives calling from door to door to solicit or deliver orders.  This trouble can easily be overcome by the use of the Battery Call Service Telephone System here described.

Made in cast iron case, the K 7915 is weatherproof and can be fixed near the service or in any other convenient position either in or outside the building. Simple to operate and efficient in its service, this system not only prevents the annoyance referred to above, but is noiseless and a time saver.

The receiver, which is fitted into an iron case attached to a flexible metal tube, when raised to the ear automatically connects the speaking battery to the transmitter, the latter is mounted on the back of the front plate and indicated by the perforated disc, into which the caller should speak.

A conversation having been finished, the receiver automatically returns to its normal position and cuts off the battery current.

The necessary wiring is simple, as only one wire from each flat to the K 7915 is necessary, and two common wires throughout from the central battery of three to four cells.

Telephone instruments K 7820, K 7842, K 7843, K 7847, K 7851 & K 7855 are suitable instruments for use in the flat.
