INSTRUCTION SHEET FOR FEDERAL SELECTFONE ® INTERCOM/PAGING SYSTEM I. GENERAL The SelectFone ® intercom and paging systems are designed for voice communication for indus- trial environments where the communication equipment is installed in high-noise areas, corrosive atmospheres, hazardous areas, and extremes of temperature, dust, and humidity. The intercom system allows the operator to both page instructions over the 15-Watt, 8-Ohm speakers and have two-way conversations between two or more people on a telephone party line. -

Handset Microphone 10 ohm dynamic noise canceling Receiver 170 +/- 30 ohm high efficiency dynamic Coil Cord 6 conductor, 10-ft extended Agency Approvals UL, cUL Models SF-1011DT, SF-1015DT, SF-1011P & SF-1015P are listed for Class I, Div. 2 Grps. A, B, C & D. - Page 5 A. Unpacking After unpacking the unit, examine it for damage that may have occurred in transit. If the equip- ment has been damaged, do not attempt to install or operate it, file a claim immediately with the carrier stating the extent of the damage. Carefully check all envelopes, shipping labels and tags before removing or destroying them.

Page 7: Shock Hazard
E. Electrical Connections (see Fig. 1, 4, 5) SHOCK HAZARD To avoid electrical shock, do not connect wires when power is applied. The enclosure has a motherboard that provides designated screw terminal blocks for easy and trouble free connections of system cable. It allows sufficient space for the system cable to be looped in and out. - Page 8 based on size of the power cable. Consult the National Electrical Code (NFPA 70) or Canadian Standards Association (CSA 22.1) for maximum allowable capacity of cable size used. Note that cable distance between stations as well as total cable length must be considered. Table in this section will provide guideline for cable distance (length) and number of 24VDC stations connected to it in parallel.

Paging Speaker Connection As output to the speaker from the speaker amplifier of the SelectFone station is less then 11 volts RMS, the speaker wires falls into CLASS II of the NEC code and, hence, conduit is not required except for mechanical protection.

5. Attach the conduit to the enclosure. Feed the wiring through the conduit, and bring it into the enclosure. Connect an 18 AWG twisted pair wire between SelectFone station L1 PAGE L2 and Line Balance L1 PAGE-L2 terminals. Similarly connect the 18 AWG twisted pair wire for each channel line between terminals of LINE-BALANCE assembly and corresponding SelectFone station terminals as shown in Figures 1, 4, 5, and 6. -
Page 11: Maintenance
When audio lines are balanced twisted pair, the induced noise voltage is the same on both conductors and, therefore, cancels out before it is amplified. But when the circuit becomes unbalanced, the induced noise voltage is not the same on both conductors and is, therefore, amplified and causes an audible hum or buzz. -
