1. 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 2 x 2 or 2 x 4 with supplied cross bars false ceiling tile space on a T bar grid CAUTION Installation and service must be performed by authorized personnel only Factors to Consider Before Installation e Installation of conduit and conduit adapters must conform to all applicable building codes and local ordinances e Installation in a plenum rated environment requires a wire gauge of 12 AWG to 18 AWG Conduit may be required NOTE If daisy chaining speakers in 70 V or 100 V configuration maximum wire gauge is 16 AWG If daisy chaining speakers in direct 8 ohm configuration maximum wire gauge is 14 AWG e If using seismic supports the installer provides the cables e Wiring connections depend on whether or not a distributed 70 or 100 volt audio system is installed with these speakers Loosen but do not remove a the 2 transformer cover plate l nsta ati on screws in the 2 keyhole slots Initial Steps 1 Power down all attached devices before proceeding 2 Remove the 2 x 2 ceiling tile where the FF 220T will be installed If the ceiling has 2 x 4 tiles cut the tile in half 3 Loosen but do not remove the two screws on the top terminal cover plate as shown on right 4 Slide and remov2. e the terminal cover plate which is installed with the transformer side down See below Black To Speaker Terminal Red To Speaker Terminal Black Red To Second Flexible Conduit Adapter Speaker Black g A Red Flexible Conduit From Amplifier 70V 100V Transformer Cover Plate Seismic Cable Pass 5 When using flexible conduit insert the conduit into the cover plate Thien Loop opening using an appropriate conduit adapter and secure the conduit to the plate See right Rear of Speaker FF 220T Setup Guide Continued When using speaker wires without a conduit secure the cable clamp adapter included to the cover plate and insert the wires through the clamp See right Cable Clamp Adapter 6 Proceed to steps 7 or 9 for the appropriate wiring instructions either for a distributed audio system 70 V or 100 V line distribution through the transformer or for a direct connection from an amplifier bypassing the transformer In the 70 V or 100 V distribution system block diagram below an optional speaker has been added as an example of daisy chaining FF 220T speakers to a single amplifier output Installation in a 70 V or 100 V Audio Distribution System through the transformer 7 Connect cables from the amplifier to the Additional transformer on the FF 220T terminal cover plate FF 220T oat Speaker s a Pull the wires from the amplifier through and Tens
