7.2 | final wiring checklist
BEFORE POWERING UP SYSTEM
Have you checked all home runs? q YES
Have you checked all wiring between floors (risers)? q YES
Are you sure all grounds are properly tied between power zones? q YES
Have you made sure all Data and Audio wires are tested? q YES
Check polarity of all wiring throughout, especially power cables.
If continuity is reversed at any point, some or all of the OPs
will be irreversibly damaged.
*Values are approx. based on 25’ cable run from OP to speaker and speaker to speaker.
WARNING
NEVER WORK WITH WIRE, or connect wires to OP’s,
while POWER IS ON.
TIP
Check data wires by going to the i.Lon® and refreshing OP’s after
each OP is connected. This will help to eliminate large trouble shooting
issues at the end of the job.
TIP
Check all speaker wires and speakers for good integrity, simply unplug the
1st speaker wire from the OP and connect an RJ45 to a 8 conductor CAT5 e wire on
one end and twist wire/pins 1,2 & 3 together and 4,5 & 6 together. This will give
you two leads + & -. Attach an OHM meter to the wire with the leads and attach
the other end into the first or last speaker in a run of speakers. If all is connected
correctly, you will approximate the following correct results on your OHM meter:
1 32.4
2 16.5
3 11.3
4 8.8
5 7.3
6 6.4
7 5.8
8 5.3
