Installation
SURFACE MOUNT
1. On top of the dome drive is an opening for an optional translator board. The opening has a cover that
must remain in place if a translator board is not required. A taller cover is supplied if a translator
board is installed.
If you are going to install a translator board, follow the instructions that come with the translator
board.
If you are not going to install a translator board, save the taller cover in case you ever choose to install
a translator board.
2. Prepare the ceiling as follows:
a. Using the surface mount ring as a template, drill holes for the mounting hardware.
• Standard ceiling: When mounting the dome system to a standard ceiling, use either
6-32 toggle bolts (not supplied) or #8 x 3.50-inch self-tapping screws (supplied). Refer
to Figure 3.
• Concrete ceiling: When mounting the dome system to a concrete system, use
8-32 studs and nuts (not supplied). Refer to Figure 4.
b. If you are installing a translator board, cut out the pie-shaped section from the supplied
template (refer to Figure 11 on page 25). Using the pie-shaped template, either cut a hole
through the ceiling or make a hole with a depth of 0.25 inches (6 mm).
