Installation Considerations
ATTENTION: Installation and service must be performed by authorized personnel only.
NOTE: The FF 220T comes in two ceiling tile configurations depending on the tile unit
of measurement:
• US version (part #42‑141‑03) — Drops into 2-foot x 2-foot (61 cm x 61 cm) or
2-foot x 4-foot (61 cm x 122 cm) suspended tile ceilings
• Metric version (part #42‑141‑23) — Drops into 60 cm x 60 cm
(1.97‑foot x 1.97‑foot) or 60 cm x 120 cm (1.97‑foot x 3.94‑foot) suspended
tile ceilings
Be sure to order the correct part number as the two configurations are not
interchangeable and will not fit correctly.
Installation of conduit and conduit adapters must conform to all applicable building codes
and local ordinances.
• Installation in a plenum‑rated environment requires a wire gauge of 12 AWG to
18 AWG. Conduit may be required.
NOTE: If you are daisy chaining speakers in 70 V or 100 V configuration, the
maximum wire gauge is 16 AWG. If you are daisy chaining speakers in direct (8
ohm) configuration, the maximum wire gauge is 14 AWG.
•
If using secondary attachment points, the installer must provide the cables.
• Wiring connections depend on whether or not a distributed (70 or 100 volt) audio
system is installed with these speakers.
