serves as the RJ-31/38X telephone connection
block.
FEATURES: Utilizes Solid State Surge Suppression. Protects Incoming Telephone Line. Protects AC Input From Transformer. Clamps Line-To-Line & Line-To-Ground. Self-Restores After Surges Within Rating. RJ31/38X 8 Position Modular Jack. Rugged, Easy To Mount Plastic Case. Packed In Reusable Poly Storage Box. Lifetime Limited Warranty.
SPECIFICATIONS: Response Time: < 1 Nanosecond. Breakover Voltage:
Telephone Line: 300 Volts.
AC Power Line: 50 Volts. Peak Pulse Current:
Telephone Line: 100 Amps.
AC Power Line: 50 Amps. Ground Wire: 24" - 14 Gauge Stranded.
This device complies with Part 68 of the FCC rules.
FCC Reg. No. 5K6USA-23140-XP-N Ren No. 0.0B.

05/02 CONNECTIONS
EARTH
This terminal must be connected to a good quality earth ground using a 14-16 gauge wire. The best choice of
GROUND
ground is : Copper or galvanized ground rod (6' or longer) driven into the ground OR a copper cold water pipe.
Do not use PVC pipe! An acceptable but less preferred ground is the screw on an electrical outlet.
TELCO
RING - Connect one side of the Incoming Telephone Line pair. (Commonly colored RED)
TIP
- Connect the other side of the Incoming Telephone Line pair. (Commonly colored GREEN)
HOUSE
R1
- Connect one side of the pair returning to the House Phone(s). (Commonly colored BLACK)
T1
- Connect the other side of the pair returning to the House Phone(s). (Commonly colored YELLOW)
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.
POWER
Optional! Provides transient/surge suppression for the low voltage transformer power line input to the control.
(DATA)
CAUTION: UNPLUG TRANSFORMER UNTIL ALL CONNECTIONS ARE COMPLETE!
IN (A & B)
- Connect the two wires coming from the Transformer. Max. input is 24 volts AC.
OUT (A & B) - Connect the two wires going to the Control. Polarity is not important with the AC.
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.
