Delta System Installation (cont.)
tuner's box or the "miscellaneous box" (if no MT-3000 short wire is found, you can make one
by following the instructions in the Appendix of this manual for MT-3000's). You can connect
the MT-3000 to its BI-3000 with this wire and then connect the BI-3000 to one of the ADA Bus™
"short-wires". The two ADA Bus™ "short-wires" for the SSD-66 can be connected to its BI-3000
as well. It is important to note that the BI-3000 has a distinct input and output. The input is
marked "Unit" and connects to the MT-3000 or SSD-66. The output is marked as "ADA Bus™"
and will be connected to the WH-3000 in "Step K". Do not connect any "short wires to the WH-
3000 at this time.
Step J - AC Connections
After you have assembled the rack and connected all the wires (except the ADA Bus™ "short-
wires" to the WH-3000, you may plug the Delta-88 or ACC-3000 (Main Power Switch), RPS-1s,
and ACC-3s into the appropriate AC wall outlets. You are now ready to begin connection and
testing of the ADA Bus™ "short-wires" to the WH-3000.
Step K - Connection of ADA Components to the WH-3000
WH-3000 Wire Harness
- The WH-3000 Wiring Harness provides a clean and proper installa-
tion platform for wire termination. A total of ten (10) connectors are used on the WH-3000,
eight of which provide thermally protective relays. Each connector has a "J" number assigned
to it, with an order of J1 through J10. The first two connectors, J1 and J2, are used as primary
WH-3000 inputs. When using only one WH-3000, the Delta-88 connects directly to J1 and J2
is left unused. When using multiple WH-3000s, the first Delta-88 (Main Power Switch or
Primary Delta-88) is connected to J1 on the first WH-3000 and the second WH-3000's J1
connector is connected to the first WH-3000's J2 connector and so on. The remaining ADA
Bus™ components, including all keypads, IR transceivers, multi-tuners, surround sound
decoders, can plug into any of the remaining WH-3000's connectors (J3-J10). Do not connect
any "short wires to the WH-3000 at this time.
Critical Wiring Tips
The Delta System, like any complex network, permits several components to communicate to
each other over the same data wire. ADA suggests building the system and testing each
component as it is added onto the WH-3000. Therefore, if a problem exists, it will be noticed
immediately and can be isolated to the last component added to the ADA Bus™. After each
step, stop and test the system. This methodical building block approach may save several
hours of tedious backtracking and troubleshooting should a wire strand be frayed. As you
begin this step by step process, it may be necessary to refer to other sections in this manua. Once
you have tested one keypad and the Delta-88, move to the next step and build the mainframe.
After the mainframe is operating, you can begin to add additional rooms. Again, you will need
to download each keypad with information from the Delta-88 as you add the keypads, one at
a time, to the WH-3000. Do not connect any "short wires to the WH-3000 at this time.
