6.
Connect a run cable from
the specified OUTPUT jack
on the module to the INPUT
jack of the first emitter.
Listen to each emitter as it is
connected. If you cannot hear
its “whooshing” sound:
a.
Try a different emitter.
b.
Test all four previous
cables for continuity and
shorts. Repair any faulty
cables.
c.
If a short is detected, the
masking will shut off until
the short is physically
fixed. The error on the
control module will
remain until the error is
cleared. (see Clearing
Error Codes, page 12)
DO NOT put the input cable into
the output port of the emitter. If
sound is only heard by putting
the cable in the output, there is a
problem earlier in the cable run.
Be sure to fix any problems and
hear the “whooshing” sound
before installing the next emitter.
7.
Connect the next OUTPUT
cable to the emitter OUTPUT
jack.
8.
Run the cable to next
designated tile specified on
emitter layout and wiring
diagram. Tie cables up to
structure or suspend from
deck as required by local
building code.
9.
On the next emitter, connect
this cable to the INPUT jack.
10.
Repeat Steps 4 through 9 for
the remaining emitters on the
home run.
11.
Set sound masking volume
levels for each zone, using
either the front panel controls
or the software interface. Set
sound levels according to
Table 1.
