Systems for all requirements-for 4 telephones or 400-the larger systems providing many Special Services, if desired. TO FIND THE RIGHT " Intercom., Idealfone and Serv·U-Fone systems are all of the "pushbutton, common-talking" type-that is, pushbuttons on each telephone provide for signaling the station desired. Four methods of operation are available: Private line-for two stations. A pushbutton on each telephone provides for signaling the other station. Selective signaling-sounding the signal at only the particular station desired. Each telephone is equipped with a number of pushbuttons-one for each station-and all telephones are connected by a cable. Code signaling-sounding the signals at all stations at once, and indicating by means of a prearranged code the particular person desired. Each telephone has one pushbutton, and only a pair of wires are required for signaling. Master-station operation-In this method of operation, one "master" station can make calls to a number of outlying stations (selective signaling is provided), and the outlying stations can call the master station, but cannot call one another (except that the master station may complete such calls if desired).

Recommended for schools and other organizations, to meet any need for a master-station system with capacity of more than ten outlying stations. A feature of this system is "group ringing," which permits arranging the telephones in groups of ten, and signaling one or more complete groups by simple key operation. In the Type 33AlO Intercom. system, the master station has 10 keys, mounted in a small walnut desk cabinet, for station selection. Five keys select the "tens" groups, and the other five select individual lines in the groups. Thus, to call any line, it is necessary merely to operate a "tens" key, and then a "units" key, which rings the desired bell. For "Group ringing" all of the stations in one or more groups, the "tens" keys of these groups are operated, and the operation of a master ringing key then rings the signals of the desired stations. The outlying telephones may be of either of the types shown herewith. These telephones have no pushbuttons-the master station is signaled automatically, the instant a handset is removed at any station. Each telephone is equipped with a buzzer signal. The Type 33AlO Intercom. system operates on 12 volts, D.C. Where the commercial current is 105-125-volt, 50-60-cycle, A.C., we recomn::'end the use of Battery Eliminator, Cat. No. PE-IO for talking current supply, and a transformer to supply ringing current. Where this commercial current is not available, storage batteries and a battery charger will be required (full information on request). The power supply should be connected to the master station. Wiring required includes two common talking wires, connected to all stations, and a separate signaling wire from the master station to each outlying station. Cat.

Auto-Com telephones provide station selection by means of "dial" operation-modern, simple, and familiar to everybody. And the Auto-Com permits not only one, but any number of conversations at one time. Auto-Com telephones are available in both desk and wall styles. The desk telephone has a signal buzzer, a terminal block for line connections, and an impedance coil (required in the talking current supply circuit), contained in a compact wall box, and connected to the telephone by means of a 6-foot flexible cord. The wall box is fitted with screw terminals for the spade tips of the cord, and solder terminals for the line cable. The wall telephone contains a similar terminal block. A call is made by removing the handset from the cradle and turning the dial from the number of the called station to the finger stop. The dial remains in this position, connecting to the desired line, and the called station is signaled by pressing a pushbutton on the telephone. When the handset is replaced after conversation, the dial automatically returns to its normal position. Cat. No. AM-73 Diam., 5% in.; height, 5 in.; handset, 9 in. long. Includes cord, and wall hox9%, x 2% x 2% in. The Auto·Com system requires a separate wire for each station, together with one common pair for signaling, and one wire for common talking return-a total of 13 wires. Fifteen-conductor cable, Cat. No. B-15 or L-15, is recommended for this system. The system operates on a direct current supply of 6-12 volts. Where reliable 105-125volt, 50-60-cycle A.C. commercial power is available, we recommend the use of Battery Eliminator, Cat. No. PE-lO. An alternative method is to use two 6·12-volt dry batteries (each consisting of four to eight cells in series), one for the talking and the other for the ringing current supply. Cat.

The telephones are slightly smaller and more compact than ordinary public-exchange telephones; and the handsets are of metal instead of molded plastic, as used in the larger systems. However, the telephones are durably constructed and nicely finished and as they operate on dry cells, operating cost is negligible. Serv-U-Fone systems may therefore be recommended where private telephone service is desired at lowest possible cost. Signaling is accomplished by simply pressing the plunger on which the handset normally rests (or, where selective signaling is employed, pushbuttons are provided for this purpose). Each instrument is furnished with a terminal block providing screw terminals for connections to dry cells and telephone line, and full instructions for wiring are supplied with each system. Descriptive Labeling Although the telephones of various Serv-U-Fone systems are identical in appearance, they have different wiring, and must be used only in the system for which they are intended_ To prevent confusion, the various telephones and other parts are individually boxed, and plainly labeled, the color of the label on each carton indicating the particular system in which it is to be used. Thus, when a system is ordered, it is easy to avoid error, by merely verifying that all packages bear labels of the same color. Green-Label Serv-U-Fone System (2 Station, Private Line) A simple but effective call-and-return system for service between rooms, from house to garage, store to stockroom, etc. Complete system consists of two wall or desk type telephones (or one wall and one desk telephone), a two-wire line, and four dry cells (two at each station). The desk telephone is entirely self-contained, including the signal buzzer, and is furnished with a 3-conductor flexible cord, ending in a small terminal block to which the battery and the line are connected. The wall telephone is similar to that shown on page 15, and contains a signal bell, and a terminal strip. Tele· phones are durably finished in "old brass" enamel. Each telephone is furnished with 50 feet of single-conductor wire, suitable for inside use in dry locations. Additional wire can be supplied for inside or outside use, as listed below. Serv-U-Fones will operate over a distance of 500 feet with four dry cells-for greater distances, use additional batteries. Cat.

System consists of one master desk telephone with seven numbered pushbuttons arranged to signal any of the other stations, and from two to seven outlying instruments. The outlying telephones can signal only the master station, but any call may, if desired, be extended to another outlying station. , The master telephone is a desk-type instrument, provided with a 10conductor flexible cord for connection to a battery box, which contains the signal buzzer. The outlying stations may be either desk or wall type, the wall set having a bell, and the desk set a buzzer signal. Desk telephone has a 4-conductor cord and terminal block; wall set has built-in terminal strip. All telephones are finely finished in "old brass" enamel. The battery box furnished with the master telephone provides for four dry cells (order separately), which are adequate to operate the system for many months under normal conditions, for distances of up to 500 feet between the most distant stations. It contains also an impedance coil, and terminal strips providing screw connections for the telephone lines. Cat. No. RPI34 Tel., 5 %, in. diam.; handset, 8 in. 19.; overall height, 3 % in. Batt.
