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.
