Refer to www.extron.com for the complete
TLP Pro 320m and TLP Pro 520M user guide

and installation instructions before

connecting the product to the power source.

Overview

The Extron BB 1 back box is used to mount an Extron TLP Pro 520M or TLP Pro 320M TouchLink® panel in a wall. This Installation
Guide provides instructions for experienced, professional installers to retrot the box in existing drywall or mount the back box
in a new installation. For complete instructions about installing and calibrating the TouchLink panel,
see the TLPPro 320M User Guide or the TLPPro 520M User Guide, at www.extron.com.

ATTENTION: The installation shall be in accordance with the applicable provisions of

National Electrical Code ANSI/NFPA 70, article 725 and the Canadian Electrical Code
part 1, section 16.

NOTE: The diagrams in this guide show the TLP Pro 520M. The TLP Pro 320M is mounted

in exactly the same way.

Retrofit an Existing Installation (with the Drywall in Place)

1. Separate and remove the end plates from the U-plate.

2. Use the back surface of the U-plate to mark the position of the hole in the drywall. Use a level

to ensure the U-plate is level.

NOTE: The hole is 5.67 inches (14.4 cm) wide x 3.8 inches (9.7 cm) high.

3. Using a drywall saw, carefully cut a hole for installing the touchpanel. Cut on the lines that you

marked in step 2.

4. Insert the U-plate to test the size of the hole. If necessary, use a rasp or le to enlarge the

hole.

5. Run the exible cable conduit inside the wall. For a retrot, the conduit should be attached to a

knock-out hole in either the top or bottom end plate.

The BB 1 accepts both 0.5 inch and 0.75 inch conduit.

6. Run cables through the conduit to the installation site. Leave some slack to connect the

conduit to the back box and the cables to the touchpanel.

7. Clear the exible conduit and cables from the space behind the hole.

8. Insert the U-plate into the hole (see gure 1).

NOTE: The U-plate tabs sit on the outer surface of the drywall.

9. Pull back the exible conduit and cables that were cleared out of the way in step 7 and

loosely attach it to the knock-out hole in one of the end plates (see gure2) using the
locking nut.

10. Hold the bottom end plate at a slight angle and slide the front edge under the bottom of

the U-plate until the end plate is inside the drywall (see gure3).

11. Align the holes in the side anges above the mounting screws on either side of the

U-plate (see inset in gure 4).

12. Push the bottom end plate down over the mounting screw and then pull it forward so

that the mounting screw sits in the slot of the end plate and the front of the end plate is in
contact with the back surface of the drywall.

NOTE: Do not tighten the mounting screws. Although the end plates are only

loosely attached to the U-plate, they will be rmly secured in place when
the locking arms of the TLP Pro 520M are tightened (see Mounting the

Touchpanel on the next page).

13. Repeat steps 10-12 to attach the top end plate to the U-plate.

14. Tighten the locking nut to secure the exible conduit attached to the end plate in step9.

15. Install the TouchLink panel (see Mounting the Touchpanel below).

New Construction Installation

To install the BB 1 at a new construction site, before the drywall is
secured to the studs:

1. If necessary, secure the end plates to the U-plate (see

steps10-13 on the previous page)

2. Place the wall box in a suitable place with the tabs on the sides

of the box at against a vertical stud (see gure 5).

3. Secure the wall box to the stud (metal or wooden) using two

nails or screws (see gure 5).

4. Run the exible cable conduits to the box. Leave enough cable

to provide slack for installing the TouchLink panel.

The BB 1 accepts both 0.5 inch and 0.75 inch conduit.

5. Attach the exible conduit to one of the end plates or to the free

side of the U-plate (see step 9 on the previous page).

6. Measure the position of the back box, and mark and cut a hole

in the drywall where the box is placed.

NOTES:

• The hole is 5.67 inches (14.4 cm) wide x 3.8 inches (9.7 cm) high.

• The tabs of the wall box must be in contact with the front surface of the stud and the inner surface of the drywall.

7. Secure the drywall to the studs.

Mounting the Touchpanel

For complete instructions about installing and calibrating the
TLPPro 320M or TLPPro 520M, see the TLP Pro 320M User
Guide or the TLP Pro 520M User Guide, at www.extron.com.

1. Connect the cables to the back of the touchpanel (see the

user guide). Feed excess cable back into the conduit.

2. Test the connections and congure the touchpanel (see the

user guide).

3. Fold the locking arms into their recesses on the side of the

touchpanel and slide the unit into the back box.

4. Tighten the screws on the front of the wallplate adapter

to rotate and tighten the locking arms behind the top and
bottom plates of the back box and hold the wallplate adapter
in place (see gure 6). Do not overtighten the screws.

NOTE: As the locking arms tighten, they secure the

endplates of the BB 1 in place by clamping them
against the dry wall.

5. Snap the touchpanel into position (see gure6).

Tabs are against
