Nexus Contractor™ Commercial Speaker System Specifications:
Pre-construction:
Choosing Your Speaker Location and Pre-wiring the Job:
Carefully select areas of the ceiling where there are no obstructions, plumbing, heating/AC apparatus or
electrical wiring.
For sheetrock ceilings, use the enclosed C-Bracket as a cut out guide, tracing the inner dimensions of this
bracket on your sheetrock ceiling, then proceed to cut out the circle to establish mounting hole.
On drop ceiling installations where the ceiling tiles will not support the weight of the speaker, use
the accompanying pre-mounted brackets to support the weight of the speaker. Each bracket has two
elongated support brackets and a center C-Bracket that have dog-eared sides that rest on the elongated
support brackets and then are secured by the enclosed screws.
After selecting your brackets location, cut holes through the ceiling tile that line up perfectly with the
placement and diameter of the C-Brackets.
Upon finalizing speaker location and cutting holes, pre-run speaker wire through ceiling to be available
upon speaker installation.
