RF Eliminator Placement Illustrations


HARD WIRE INSTALLATIONS:

NOTE: Soldering is NOT required. Use the supplied "Beanies," which can be crimped with a pliers.


LOOP SERIES WIRING (House Type) INSTALLATIONS:

NOTE: X indicates points in wiring where filters may be placed.

Filters can be Hardwire or Modular. We have 1 Line or 2 Line Modular Filters (2 or 4 wires).

A Hardwire Filter may be needed in the middle of a cable run (X).

 

PARALLEL DISTRIBUTION WIRING INSTALLATIONS:

NOTE: X indicates points in wiring where Filters may be placed.

Filters can be Hardwire or Modular. We have 1 Line or 2 Line Modular Filters (2 or 4 wires).

A Hardwire Filter may be needed in the middle of a cable run (X).

 

TWO LINE TELEPHONE WIRING INSTALLATIONS:

NOTE: X indicates points in wiring where Filters may be placed.

Filters can be Hardwire or Modular. We have 1 Line or 2 Line Modular Filters (2 or 4 wires).

A Hardwire Filter may be needed in the middle of a cable run (X).

Two line telephones are treated similar to single line phones. Use 1 Line Modular Filters for each line individually, or use 2 Line Modular Filters at the two line telephone set(s).

 


PLACEMENT AT JACKS AND PHONES:

    A - Hardwire Filter breaking up the line in loop series wiring (like at houses).

    B - Placement of Hardwire or Modular Filter at wall jack.

    C - Hardwire or Modular Filter at line input to telephone.

    D and E - Handset Filter blocking interference to the telephone when the handset cord intercepts the RFI. I've only seen location E needed once, so it will usually go at D.

 

ELECTRONIC KEY SYSTEM / PBX WIRING:

NOTE: X indicates points in wiring where Filters may be placed.

Filters can be Hardwire or Modular. We have 1 Line or 2 Line Modular Filters (2 or 4 wires).

D and E - Handset Filter blocking interference to the telephone when the handset cord intercepts the RFI. I've only seen location E needed once, so it will usually go at D.

Proper filter selection for the CO Lines on the KSU depends on wiring configurations.

When RJ-11 jacks supply single line phones, use 1 Line Modular Filters.

When RJ-14 jacks supply two lines, use 2 Line Modular Filters.

If the system is fed by an RJ-21X, use Hardwire Filters on each incoming line.

Our 2 Line Modular Filters are compatible with the stations side of electronic key telephone systems and PBXs.
