Ceiling or Wall Bay Installation
1 Run the speaker wire to the installation location. Be sure the wire meets electrical and building code
requirements.
2 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. Snap a ULM connector into each of the
knockouts removed.
3 If you are using a 70/100 V constant voltage transformer, mount it on the mounting studs provided inside the FRB.
4 Position the FRB unit between the rafters or studs. The mounting holes in the front plate align with common rafter/stud
separation. Center the mounting screw holes over the rafter/stud and level the FRB.
5 Fasten the FRB to the rafter/stud with at least 4 screws.
6 Before installing the drywall, carefully measure the location of the FRB unit and cut the appropriate hole. The hole cutout
diameter is listed in the specifications table.
7 Connect the speaker (and the 70/100V transformer if it is used) and mount the speaker according to the instructions
supplied with it.
