3M™ Drive-Thru System Model G5
9. 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.
When installed according to the guidelines below, these components act together as a system to help enhance speech intelligibility.
B. Installation Guidelines - Separate Housings
Component installation is the same for both the microphone and the speaker housings.
Installation Instructions G5 - Revision C, September 2019
A. System Components
• 6 each, 2" x 10" 3M™ Vibration Control Tape
• 2 each. 1" x 8" x 27" TUFCOTE
• 2 each, 2" x 12" x 30" Thinsulate™ Acoustic Insulation
• Ensure that the inside of the housing is clean and dry.
• Install the 3M™ Vibration Control Tape to the inside of the top and side walls of the housing (Figure 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
(Figure 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 (Figure 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.
• If there is excess insulation, overlap it against the inside of the first layer.
