Solid-core “Romex” type wire is not acceptable! Use at least 16AWG speaker wire for runs up to 100 feet, and at least 14 AWG speaker wire for runs up to 200 feet. If you must cross high-voltage lines, always do so at a 90 degree angle to avoid audible hum through the speakers!. Note 3: When pre-wiring for ceiling speakers, it is essential to make direct wire runs from the head-end to each speaker. Do not run speaker wires in series or parallel, and do not “daisy-chain” speakers to common wiring. Storm Series Ceiling Speakers Pre-Wiring The audio/speaker cable runs should be routed from the head-end location to the speaker rough-in brackets (if used). At the speaker locations, securely fasten the speaker wire to the speaker rough-in bracket. If not using speaker rough-in brackets, staple speaker wire runs in a loose zigzag between the studs where the speaker is to be mounted to make it easier to find the cable after the drywall is installed. Zig-zagging the cable also allows flexibility in the placement of the speaker. Note: Do not run speaker wires closer than 12" from high voltage wires. Speaker Wire Min 12" High Voltage Wiring Figure 3.8 - 12" From High-Voltage Wiring Speaker Ceiling Speaker Wire Cutout Figure 3.9 - Pre-Wiring Mounting Two situations that can exist when mounting ceiling speakers: • Pre-Construction -Installations that occur in new homes being built and in remodel situations where walls and/or ceilings will be exposed. • Retro-Fit - Installation that involve existing homes with walls and ceilings finished. While the end result of either type of installation is similar, the process is quite different. Pre-Construction In a pre-construction installation, walls and ceilings are open with no drywall installed. This is desirable and allows the installer greater access than in retro-fit applications. ATON model BK6C Rough-In Brackets are specifically designed to work with models A60C/A61C/A62C, A62ST/ A63C while model BK8C Rough-In Brackets are designed to work with A81C/A82C speakers. Rough-in Brackets should be used whenever possible to reserve a neat hole in the drywall, ensuring proper speaker placement and making trim-out and final installation neat and organized. © 2007 • All rights reserved. 8 ©2007 • All rights reserved. Storm Series Ceiling Speakers BK6C/BK8C Rough-In Bracket Figure 3.10 - Rough-In Bracket Mounting Rough-In Brackets Once the mounting locations are decided upon, assemble the brackets and secure them to the ceiling joists using fl at-head screws or heavy-duty staples (see the ATON Ceiling/In-Wall Rough-In Brackets Manual for detailed steps). Retro-Fit Retro-fi t installations are more diffi cult to complete than pre-construction because walls and ceilings are intact. Typically wires must be fi shed into position through walls, fl oors and ceilings. Holes must be cut and speakers mounted directly in the ceiling with no rough-in brackets. Note: Before cutting holes in any existing wall or ceiling surface, probe t...
