FF 220T • Setup Guide
This setup guide contains installation information about the Extron FF 220T Flat Field ® speaker. This speaker is designed for use
in plenum rated ceiling spaces and can be dropped into a standard square (2-foot by 2-foot or 600 mm by 600 mm) or rectangular
(2-foot by 4-foot or 600 mm by 1200 mm with supplied cross bars) false ceiling tile space on a T-bar grid.
WARNING: May result in serious injury. 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' x 2' (61 cm x 61 cm) or 2' x 4' (61 cm x 122 cm)
suspended tile ceilings
• Metric version (part #42-141-23) — Drops into 600 mm x 600 mm or 600 mm x 1200 mm suspended tile
ceilings
Be sure to order the correct part number as the two configurations are not interchangeable and will not
fit correctly.
Factors to Consider Before Installation
z Installation of conduit and conduit adapters must conform to all applicable
building codes and local ordinances.
z Installation in a plenum-rated environment requires a wire gauge of
12 AWG to 18 AWG, as shown on the right. Conduit may be required.
z If using secondary support cables, the installer provides the cables.
Installation
1. Disconnect power — Power down all attached devices before proceeding.
2. Remove and cut ceiling tile — Remove the square ceiling tile where the FF 220T will be installed. If the ceiling has
