GMK 1 • Installation Guide
The Extron GMK 1 (see gure to the right) is an accessory for the
SMB1 kit and is used to mount the TLP Pro 320M or the TLP Pro 520M
on a glass surface. This guide provides instructions for experienced,
professional installers to mount and install either touchpanel using the
GMK 1 and SMB 1 mounting kits.
The GMK 1 is a at plate with a powerful adhesive on one surface that
bonds strongly to a glass surface. The opposite surface has four studs
(one in each corner) for securing the SMB 1.
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
TLPPro 320M is mounted in exactly the same way.

Securing the GMK 1 to a Glass Surface
1. Decide where the touchpanel will be placed and clean
the surface of the glass with a 50:50 mixture of isopropyl
alcohol and water.
2. Use a level and apply painter tape to the glass to mark
the position where the GMK 1 will be mounted.
ATTENTION: The lower edge of the GMK 1 is the
shorter edge with the notch.
3. Remove the backing from the surface of the GMK 1 to
expose the adhesive.
4. Carefully align the lower edge of the GMK 1 with the
tape from step 2. Hold the GMK 1 at a slight angle so
that the adhesive does not come in contact with the
glass until you are ready to press it into place.
ATTENTION:
• Once the GMK 1 is attached to the glass, it
is very difcult to remove. Align the GMK 1
exactly where you need it before pressing it
into place.
• If you need to remove the plate, slide a thin
wire or use a ne tooth saw or other sharp
cutting tool between the plate and the glass.
Once the plate has been removed from the
glass, it should not be reattached.
5. Once aligned, angle the GMK 1 onto the glass and press
rmly. If possible, allow the bond to set for 72 hours for
maximum strength.
CAUTION: The maximum load for the GMK 1
must not exceed 5 lb (2.27 kg).
