Crestron MMK-4L & WMKM-4L Mud Mount Kits

Mud Mount Kits: MMK-4L &

WMKM-4L

Description

Mud Mount Kits are the preferred mounting option for the Crestron Isys®

TPS-4L and TPMC-4L wall mounted touchpanels when cutouts made in the drywall

for touchpanel installation are too large. These kits provide support for additional

plastering that can be applied to hide large irregularities in the touchpanel cutout.

NOTE: If mounting into another material (other than drywall – for example, wood

lectern, concrete, or rock) use the cutout template, available in the post-construction

kit WMKM-4L. For concrete and rock mounting material, allow for proper

ventilation before mounting the touchpanel.

There are two Mud Mount Kits. The MMK-4L is a pre-construction accessory.

Pre-construction refers to framed walls prior to hanging drywall. This accessory

must be used with either the Pre-Construction Mount Kit (PMK-4L) or Back Box Kit

(BB-4L).

The WMKM-4L is a post-construction kit. Post-construction refers to framed walls

with drywall hung. This accessory is designed with a mounting plate so that it can be

placed anywhere on a wall without the support of a stud.

NOTE: If necessary, consult the latest revision of the TPS-4L Operations Guide

(Doc. 6449) or the TPMC-4L Operations Guide (Doc. 6450) for a complete list of

mounting options. Both documents are available from the Crestron website

(www.crestron.com/manuals).

Supplied Hardware

The MMK-4L consists of three parts. These parts produce an assembly that attaches

to the PMK-4L or BB-4L. The WMKM-4L consists of five parts–three of which

make up the MMK-4L–as well as one mounting plate and one cutout template. The

mounting plate provides the necessary support for post-construction applications.

Installation

This section provides an installation procedure for each Mud Mount Kit. The

procedure for the MMK-4L starts below and the “WMKM-4L Procedure” starts on

page 6. Be sure to review each procedure before starting.

MMK-4L Procedure

The procedure in this section provides the necessary steps for the assembly of the

MMK-4L to either the PMK-4L or BB-4L. It is assumed that the PMK-4L or BB-4L

has been secured to the stud according to the procedures in their latest Installation

Installation Guide – DOC. 6389 Mud Mount Kits: MMK-4L & WMKM-4L •3

Mud Mount Kits Crestron MMK-4L & WMKM-4L

Guides (Doc. 6388 and Doc. 6387, respectively). Also, it is assumed that drywall is

in place and a rectangular cutout for the touchpanel is made in the drywall.

Complete the steps in the order provided. The only tools or materials required and

not supplied are a drywall saw or equivalent, four standard drywall screws, #2

Phillips screwdriver, a level, and tools/material to apply drywall joint compound.

CAUTION: Allow an air gap of at least 12 inches in the wall cavity above and

below the touchpanel for heat dissipation.

NOTE: The illustrations in this procedure show the installation of the MMK-4L

with the PMK-4L. Even though the illustrations only show the PMK-4L, they are

identical for the BB-4L as well.

1. Pass an adjustment plate through the opening and align its two center

holes with the top two pins on the PMK-4L. Verify that the pins on the

adjustment plate are not between (facing) the adjustment plate and the

PMK-4L. Refer to the illustration after this step for visual guidance.

2. Slide a push-on fastener over each pin of the PMK-4L (or

BB-4L) to loosely secure the adjustment plate and the mounting plate.

Do not push the push-on fasteners all the way down onto the pins. Slide

them on enough to keep the adjustment plate and mounting plate as one

adjustment/mounting plate assembly.

3. Use the second adjustment plate and repeat steps 1 and 2 using the

lower two PMK-4L (or BB-4L) pins.

NOTE: When installing into the PMK-4L, verify that the 18 AWG bus wire

securing the cables for the touchpanel remain attached.

illustration after this step.

5. When the mud ring plate is in position, bend the top two flanges of the

plate upward and the bottom two flanges downward.

• If mounting into the PMK-4L, bend the flanges approximately

90 degrees.

• If mounting into the BB-4L, bend the flanges back as far as they

can go.

6. Use four standard drywall screws (length should not exceed drywall

thickness by more than ½ inch) to secure the mud ring plate to the rest

of the assembly. The screws pass through the clearance holes in the

PMK-4L (or BB-4L) and are secured in the extruded holes of the

adjustment plates.

7. Verify that the mud ring plate is level.

NOTE: Do not over tighten screws. Doing so may over-dimple or rip the mud ring

plate.

8. Use a #2 Phillips screwdriver and tighten the drywall screws by hand

so that they slightly dimple into the holes in the mud ring plate.

9. Apply drywall joint compound as needed to finish the cutout. Avoid

covering the four tapped mounting holes.

10. Run the necessary cables for the touchpanel and secure them behind the

drywall.

11. When dry, the touchpanel can be installed using the four tapped holes

in the PMK-4L. Refer to the latest revision of the

TPS-4L Operations Guide (Doc. 6449) or the TPMC-4L Operations

Guide (Doc. 6450) for installation instructions.

WMKM-4L Procedure

The procedure in this section provides the necessary steps for the assembly and

installation of the WMKM-4L into a wall. Review the procedure and complete the

steps in the order provided. The only tools or materials required and not supplied are

a drywall saw or equivalent, a level, four standard drywall screws, #2 Phillips

screwdriver, and tools/material to apply drywall joint compound.

CAUTION: Allow an air gap of at least 12 inches in the wall cavity above the

touchpanel for heat dissipation.

1. Insert the two pins on one adjustment plate into the top two outer holes

on the mounting plate, as shown in the following illustration.

2. Slide a push-on fastener over each pin on the adjustment plate to

loosely secure the adjustment plate and the mounting plate. Do not

push the push-on fasteners all the way down onto the pins. Slide them

on enough to keep the adjustment plate and mounting plate as one

adjustment/mounting plate assembly.

3. Use the second adjustment plate and repeat steps 1 and 2 using the

lower two pins.

4. Locate an area on the wall that is free of miscellaneous wiring and

studs.

5. Make a small hole near the middle of the designated site; verify that the

location is suitable.

NOTE: Make the cutout as level as possible. The mounting plate allows for only

minor leveling adjustments.

6. Use the drywall saw or equivalent to produce a level, rectangular cutout

in the drywall as shown on page 3.

7. Insert the symmetrical mud ring plate into the opening, as shown in the

illustration after this step.

8. Carefully pass the adjustment/mounting plate assembly through the

opening and rest the assembly against the interior surface of the

drywall. Verify that the adjustment plates are between the mounting

plate and the drywall.

9. When the adjustment/mounting plate assembly is in position, bend the

top two flanges of the mud ring upward (approximately 90 degrees) and

the bottom two flanges downward (approximately 90 degrees). Refer to

the illustration after this step.

NOTE: Adjustment/mounting plate assembly will have slight play; this is normal. It

allows for minor adjustments to the touchpanel during installation.

Bend Flanges

10. Use four standard drywall screws (of adequate length) to secure the

plate to the adjustment/mounting plate assembly. The screws pass

through the clearance holes in the plate and are secured in the extruded

holes of the adjustment plates.

11. Verify that the plate is level before tightening.

NOTE: Do not over tighten screws. Doing so may damage the plate.

12. Use a #2 Phillips screwdriver and tighten the drywall screws by hand

so that they slightly dimple into the holes in the mud ring plate.

13. Run the necessary cables for the touchpanel and secure them behind the

drywall.

14. Apply drywall joint compound as needed to finish the cutout. Avoid

covering the four tapped mounting holes.

15. When dry, the touchpanel can be installed using the four tapped holes

in the mounting plate. Refer to the latest revision of the

TPS-4L Operations Guide (Doc. 6449) or the TPMC-4L Operations

Guide (Doc. 6450) for details.
