Installation Guide
The following is a set of recommended procedures to following during installation. Before you begin wiring the
system:
l
Ensure that all system interconnection and wiring diagrams required for your system are provided.
l
All backboxes (cabinets) and the associated equipment should be properly installed AND grounded via a
single, unbroken conductor (12AWG, typical). Conduit ground is NOT sufficient.
1. Connect the data line between all equipment first. To do so, you must:
l
Refer to the 2120 General System Features form to see whether each data line equipped is single line
(one pair of wires, with shield, option number 6201) or McCulloh loop (two pairs of wires, with shields,
option number 6202).
l
Refer to the appropriate system interconnection diagram to see how cabinet-to-cabinet connections are
made.
l
Refer to the individual equipment cabinet drawings to determine how the data line is terminated at each
equipment cabinet.
2. Next, connect the audio lines (if audio is equipped) between all equipment associated with the audio system. To
do so, you must:
l
Refer to the cabinet interconnection and drawing list (part of the system interconnection drawings) to see
which equipment cabinets are interconnected for the audio sub-riser configuration.
l
Refer to the appropriate system interconnection diagram to see how cabinet-to-cabinet audio connections
are made.
l
Refer to the cabinet drawings specified in the cabinet interconnection and drawing list to determine how
the audio sub-riser is connected to audio Control Points at each equipment cabinet.
3. Connect the telephone lines (if telephone is equipped) between all equipment associated with the telephone
system. To do so, you must:
l
Refer to the appropriate system interconnection diagram to see how cabinet-to-cabinet telephone line
connections are made.
l
Refer to the appropriate cabinet drawings to determine how the telephone line is terminated at each
equipment cabinet. The specification sheet (or transponder specification worksheet, for transponders) for
each piece of equipment will tell you if the telephone line is associated with that piece of equipment.
4. Connect the power lines between all equipment cabinets as required. To do so, you must:
l
Refer to the cabinet interconnection and drawing list to see which equipment cabinets are interconnected
for the power line configuration.
l
Refer to the appropriate system interconnection diagram to see how cabinet-to-cabinet power
connections are made.
l
Refer to the cabinet drawings specified in the cabinet interconnection and drawing list to determine how
the power line is connected at each equipment cabinet, if such a connection is required.
