7.2 | nal 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 CAT5e 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
