AD-C821 Installation Options

The AD-C821 Loudspeaker System is a blind-mount design made to mount into finished ceilings. The AD-C821 loudspeaker system can be mounted in suspended ceilings, as well as non-suspended ceiling types. We recommend that you consult an installation professional for safety assurance, quality installation, and optimum acoustic performance.

The Suspended-ceiling Tile Rails (Figure 6) must be used with the Split Ring bracket (Figure 5). The Suspended-ceiling Tile Rails are designed to be used with 24" (600 mm) t-channel suspended-ceiling supports to provide necessary strength for mounting.

Non-suspended Ceilings

For other ceiling types, the Split Ring bracket is used to reinforce the mounting surface.

Safety Features

The AD-C821 provides two safety features: a Seismic Mounting Tab and a Grille-retaining Safety Tether.

•The Seismic Mounting Tab is the metal tab, on top of the enclosure, suitable for securing the loudspeaker system to building framing. This provides maximum safety in the event the ceiling structure fails for any reason.

•The Grille-retaining Safety Tether is comprised of two plastic lines, one coming from the grille, the other from the loudspeaker assembly, that hook together to prevent the grille from falling.
