Attaching the tie wire

Installation, cont’d

1.Cut four equal lengths of wire, sufficient to be terminated at both ends (at ceiling and turnbuckles) with at least five loops around itself.

2.Loop the wire through the anchors, eye screws, or over the truss, and twist the wire around itself at least five times.

Figure 6 — Anchor and screw tie wire fastening

NThe final loop should be tightly bent and secured to the wire to avoid untwisting under stress.

3.Loop the wire through the turnbuckles, twisting the wire around itself at least five times to secure it.

4.Using a wrench, adjust the turnbuckles to take up slack, and to level the ceiling plate so it just rests on the grid. The four support wires should be taut, and should take the full weight of the completed installation.

5.Tighten the T-bar securing screws fully.

Threaded rod installation

If threaded rods (not supplied) are to be used instead of the supplied tie wire to secure the plate to the ceiling, insert the threaded rods through the holes at the ends of plate. Secure with washers and nuts. Adjust the length as needed to ensure the plate remains level and so it just rests on the T-bar. The rods should take the full weight of the completed installation.

Insert threaded rods through holes on the ends of the mounting plate.

Attaching the safety cable

As an added precaution, the supplied safety cable must be installed. This will help hold the mount up in the event that any of the tie wires, or threaded rods come loose or detach during an earthquake or accident.

To install the safety cable, follow the steps below:

1.When the projector ceiling mounting plate is attached to the structural ceiling and rests on the T-bar, find and mark a point directly above the plate’s center.

CDO NOT rest, or lean on the plate or suspended ceiling grid during installation of safety cable, or during installation and wiring of electrical boxes, accessories and projector.

2.At the marked location, drill a hole and install a ceiling anchor or eye screw, following the steps in “Securing the mounting plate to the structural ceiling” on page 6.

3.Pass the safety cable through the anchor and attach it with even lengths to the center holes on either side of the plate. Secure using the cable clamps.

Attach safety cable to center holes and secure with cable clamps.

NAs more items are installed (electrical boxes, projector, and pole etc.), the tire wire and safety cable may become stretched or may loosen under the combined weight.

Upon completion of the entire installation, and periodically afterwards, carefully check the cable clamps, safety cable, tie wire, and ceiling anchors to ensure they are properly secured and are taking the full weight of the installation.
