7.

Align the two slotted holes in the bottom of the L-shaped

 

bracket with the two slotted holes in the base of the tray.

 

Secure the L-bracket to the base by inserting two provided

 

6-32 x 5/16" screws through the aligned slots.

8.

Move the PMK 350 up to the desired location on the ceiling

 

pole, as close to the ceiling as desired.

9.

Secure the L-shaped bracket to the U-bolt using the

 

included hex nuts, washers, and lock washers. Tighten the

 

hex nuts securely.

NBe sure to tighten the hex nuts securely enough that the PMK 350 does not slide down the ceiling pole. A socket wrench is recommended to tighten the hex nuts.

10. Secure the front and rear plates to the mounting tray with four of the included #6 screws.

11. If desired, choose one of the provided four sizes of self- adhesive cover sheets, and apply it to the underside of the mounting tray.

Decora unit mounting

The DVI 201 A D (Decora) transmitter and receiver can be installed in a one-gang electrical wall box with a Decora wall plate cover (supplied).

The installation must conform to national and local electrical codes and to the wall plate’s size requirements.

UL/Safety Requirements

The following Underwriters Laboratories (UL) requirements pertain to the installation of the Decora transmitters and receivers into a wall or furniture.

1.

These units are not to be connected to a centralized DC

 

power source or used beyond their rated voltage range.

2.

These units must be installed in UL listed junction boxes.

3.

These units must be installed with conduit in accordance

 

with National Electrical Code.

Preparing the site and installing the wall box

Choose a location that allows cable runs without interference. Allow enough depth for both the wall box and the cables. The box should be at least 2.5" (6.4 cm) deep to accommodate the connectors and cables. Install the cables into the wall, furniture, or conduits before installing the wall plate.

NThe Decora units are very deep and have connectors on the back side (figure 2-9 on page 2-12). Extron recommends its 1-gang or 2-gang junction boxes (part #s 980130 or 980084), which have a depth of 2.5" (6.4 cm).
