Label the System Wiring

If done correctly, labeling can provide valuable information about the location of wire or cable within the building and save hours of frustrating work. There are five types of labels used for identification:

■Cable labels are white adhesive-backed tabs that are stuck to the cables to identify the source and the destination of the cables before they are pulled to and terminated in satellite closets and equipment rooms. The labels come in a variety of shapes and sizes to accommodate different sizes of cable. Use a pen or a felt-tip marker to write on the surface.

Field labels are adhesive-backed tabs that are applied to smooth surfaces in the equipment room and satellite closets. They identify components. Use a pen or a felt-tip marker to write on them.

Insert labels are cardboard-like strips that slip inside the clear plastic designation strips located between the rows of a termination or field-terminated wiring block. They are color-coded to identify the origins of cables. Along with the color-coding scheme, alphanumeric codes on the labels help to identify the specific location of the same pair or series of pairs at the other end of the cable (see Table 3-2).

■Jack labels are small, white, rectangular-shaped stick-on tabs that are stuck to the cover plate or housing of telephone outlets. They identify the location of the satellite closet where the cable to that outlet is terminated and the number of the circuit.

■Telephone cord labels are blue labels packaged with the control unit carriers and wrap around each end of the telephone cords that leave the control unit.
