OTHERWISE:
If a sound level meter is not available, the
recommended levels are likely to be achieved in most environments
by setting the control module’s masking volumes as follows:
Control Module’s Masking Volume Settings
Private Office Zones
05-09, for all ceiling heights
Open Area Zones
13-16, for 08 ft. (2.4 m) ceilings
15-18, for 10 ft. (3 m) ceilings
17-20, for 12 ft. (3.7 m) ceilings
Masking volumes must be set sufficiently high to improve speech
privacy and reduce distraction but not so high that the masking
sound becomes obtrusive. Settings within the above ranges typically
accommodate both objectives. As a general rule, use the high end
of the range. Base final settings on site conditions and customer
preferences.
Hardware Installation
Installing the Control Module
NOTE:
Always plug in/unplug power supply at wall outlet.
Wall Mount (attached to the back of the control module)
Remove the wall mount from the control module. Mount the wall
mount using the 4 screws and plastic anchors provided. Use a ¼
inch drill bit for the anchor hole. The included Plastic anchors are
#6 x 1" with #6 x 1 ¼" screws.
Use the bubble level on the wall mount to guide installation. Make
sure to completely tighten the screws to ensure proper mounting
of the front panel.
All connections are made to the control module and then the
module "snaps" into place on the wall mount.
