User manual BOSTON ACOUSTICS FRB8R

[. . . ] The three FRB models covered in the manual were designed to accommodate a variety of Boston Acoustics round in-ceiling loudspeakers. They meet the stringent requirements of electrical codes throughout the country for fire and plenum rated enclosures. Such enclosures are often required by building codes in commercial applications and in town homes or condominiums. [. . . ] Center the mounting screw holes over the rafter/stud and level the FRB. Before installing the drywall, carefully measure the location of the FRB unit and cut the appropriate hole. Connect the speaker (and the 70/100V transformer if it is used) and mount the speaker according to the instructions supplied with it. Decide which of the wire inputs you want to use and remove the appropriate knockout cover(s). If the wiring will be "daisy chained" to other speaker, remove other knockout covers as needed. If you are using a 70/100V constant voltage transformer, mount it on the mounting studs provided inside the FRB. Fasten the drop ceiling support bars to the FRB with the hardware provided. Cut the appropriate size hole in the ceiling panel over which the FRB will be mounted. Hint: For a variety of reasons it is best to center the cutout hole in the ceiling panel. Hint: Do not install the ceiling panels adjacent to the installation location until the FRB and speaker have been installed and connected. Slide the FRB through an adjacent opening in the support grid and set it in place over the cutout in the ceiling panel. Caution: Because drop ceiling support grids are not particularly strong, we strongly recommend you fasten a safety cable between the tab on the back of the FRB and a structurally strong building element. Connect the speaker (and the 70/100V transformer if it is used) and mount the speaker according to the instructions supplied with it. Boston Acoustics warrants to the original purchaser of our FRB series products that they will be free of defects in materials and workmanship for a period of 5 years from the date of purchase.
