Appendix: 3M™ Acoustic Kit Installation Guide
The 3M™ Acoustic Kit that is used for communication posts is suitable for new
or retrofit installations and can readily be used with various housing designs.
One kit contains enough material to accommodate a typical microphone and
speaker system. It can be used for a microphone and speaker installed either in a
single housing or in separate housings.
Installation Guidelines — Separate Housings
Component installation is the same for both the microphone and the speaker
housings.
•
Ensure that the inside or the housing is clean and dry.
•
Install the 3M
™
Vibration Control Tape to the inside of the top and
side walls of the housing (fig. 1).
Using a pair of scissors, cut one piece of tape approximately
1" less than the length of the top wall. Cut two pieces so they
are each approximately 1" less than the side walls.
Peel and discard the release liner from the back of the tape.
Center each piece of tape on the inside of the top and side
walls of the housing, as shown in the illustration.
•
Install the TUFCOTE
®
TBK Faced Foam to the inside of the housing
and over the vibration control tape (fig. 2).
Check the fit of the foam to the inside of the housing. The
foam can either be formed into an upside-down “u” shape to
fit against the inside of the top and side walls as one piece, or
cut into individual pieces to fit the inside of each wall.
Peel and discard the release liner from the back of the faced
foam.
Align the center of the foam with the centerline of the top wall
and then work toward the edges until the foam is centered on
the inside of the top and side walls of the cavity.
When positioned correctly, press the foam firmly to secure it
in place.
•
Install the Thinsulate
™
Acoustic Insulation (fig. 3).
Loosely line the housing with the acoustic insulation. For the
best appearance, position the black side of the insulation
toward the outside of the housing.
