[. . . ] (Commonly colored GREEN) R1 T1 - Connect one side of the pair returning to the House Phone(s). (Commonly colored BLACK) - Connect the other side of the pair returning to the House Phone(s). (Commonly colored YELLOW) TELCO HOUSE J1 - 8 PIN Connect an 8 wire modular telephone cord from J1 to the Digital Communicator. Studies have found that the MODULAR cord should be at least 3 feet long for best surge suppression. The pin assignments of J1 are: 4 & 5 are RING JACK and TIP going to the control. 1 & 8 are R1 and T1 returning from the control. 2 & 7 are shorted together by jumper EOL, creating a closed circuit tamper loop to supervise the modular plug. This loop may be converted to a resistored EOL circuit by cutting the jumper and attaching the required resistor in series with the jumper. Provides transient/surge suppression for the low voltage transformer power line input to the control. CAUTION: UNPLUG TRANSFORMER UNTIL ALL CONNECTIONS ARE COMPLETE!IN (A & B) - Connect the two wires coming from the Transformer. OUT (A & B) - Connect the two wires going to the Control. NOTE: The POWER terminals may alternately be used for surge protecting data transmission wires such as a keypad or zone expansion bus, as long as any measurable voltage on the two data wires is less than 24 volts. Connect the data wires to the IN and OUT terminals while observing polarity using the A & B markings. Jumper EOL shorts pins 2 & 7 for tamper supervision of the plug.
