Intr oduction This section gives an overview of the Extron CS 1226T SpeedMount Ceiling Speaker System, consisting of the CS 26T speakers and CS 120P enclosure.
• Selectable taps — The rotary tap selector switch, located behind the grille, sets the speaker to operate in either 8-ohm direct or 70 volt /100 volt operation with 16, 8, 4, 2, and 1 watt taps. • Magnetic grille — Magnets spaced around the grille edge enable it to be easily attached and to remain firmly in place.
Installation This section provides instructions for installing the CS 26T speakers and the CS 120P enclosure. T opics include: • Installation Considerations • Installation Configurations •.
Installing the CS 1226T System — Single Installer If a single installer is installing the CS 1226T system, follow this procedur e for the entire system: NOTE: The ceiling grid must be installed before the installation of the CS 1226T begins.
e. Cut out the circle traced in the ceiling tile. f. Replace the tile in the ceiling. 4. R emove the adjacent ceiling tile — T o facilitate the installation process, r emove the tile adjacent to the ceiling tile where the CS 26T will be installed. If the CS 120P is being installed, skip to step 6.
8. Route the cables through the cover plate — NOTES: • The CS 120P is fully UL 2043 compliant only when it is used with a metal conduit or with plenum rated cables. • Installation of all conduits, conduit adapters, wiring, and electrical connections must conform to all applicable building codes and local ordinances.
9. Wire the CS 120P — Route the wir es through the H-shaped opening in the CS 120P . Be sure to leave suf ficient slack. Figure 8. Route the Wires Thr ough the H-shaped Opening 10. Replace the terminal cover plate — Reinstall the terminal cover plate onto the CS 120P and tighten the two screws that wer e previously loosened.
12. Place the CS 120P into the ceiling grid — Place the CS 120P over the tile grid so that the CS 120P is safely supported on the two short edges. Ensure that the hole in the tile is aligned with the hole in the CS 120P (see figure 10).
16. Attach the speaker wires to the captive screw connector — A TTENTION: Do not tin the wires. Tinned wires do not r emain tight in the captive screws and can br eak easily after several bends.
• Wiring Multiple Speakers Using Loop-through: A loop-through electrical connection is made on the cr ossover board of the CS 26T . Connect the wires to the captive scr ew connectors of the speakers, as shown in figure 15. Be sur e to tighten the screws.
• The impedance of the speakers downstream of the one being tested can be measured while the system is on by connecting to the outer (LOOP) terminals of the captive screw connector , as shown in figure 17. Impedance T est Points To next speaker(s) Red Wire (+) fr om Amplifier Black Wire (-) fr om Amplifier Amplifier Te st Points Figure 17.
18. Attach the speaker wire to the strain relief tie down point using the pr ovided zip tie. Captive Sc re w Connector Strain Relief Ta b (zip tie) Figure 19. Attaching the Speaker Wir e to the Strain Relief Point 19. Mount the CS 26T (see figure 20).
20. Attach secondary support lines — If requir ed, attach all of the secondary support lines as shown in figure 21. A TTENTION: Do not allow any slack in the support cables. NOTE: If the CS 26T will be installed in the CS 120P , do not attach secondary support cables to the speakers.
22. Set the rotary tap selector switch — Use a small screwdriver to set the tap selector switch to the appropriate setting. A TTENTION: When setting the taps for a distributed (high impedance) system, do not tap the system above the rated power of the amplifier .
Installing the CS 120P in a Suspended Ceiling — Division of Labor In a division of labor installation, low-voltage contractors install the CS 120P enclosure (construction rough-in phase). NOTE: The ceiling grid must be installed before the installation of the CS 1226T can begin.
4. Cut a hole for the CS 26T speaker . Use the provided cutout template to outline the hole to be cut in the ceiling tile as described below . (If the ceiling tile will not be installed during this phase of the installation, skip to step 6 .) a. Remove the ceiling tile.
7. Route the cables through the cover plate — NOTES: • The CS 120P is fully UL 2043 compliant only when it is used with a metal conduit or with plenum rated cables. • Installation of all conduits, conduit adapters, wiring, and electrical connections must conform to all applicable building codes and local ordinances.
8. Wire the CS 120P — Route the wires through the H-shaped opening in the CS 120P . Be sure to leave suf ficient slack. Figure 29. Route the Wir es Through the H-shaped Opening 9. Replace the terminal cover plate — Reinstall the terminal cover plate onto the CS 120P and tighten the two screws that wer e previously loosened.
11. Place the CS 120P into the ceiling grid — Place the CS 120P over the tile grid so that the CS 120P is safely supported on the two short edges. If the ceiling tile was installed, ensure that the hole in the tile is aligned with the hole in the CS 120P (see figure 31).
Installing the CS 26T in a Suspended Ceiling — Division of Labor In a division of labor installation, an A V system contractor installs the CS 26T (final installation phase). Use the following procedur e: NOTE: Observe all applicable building codes and local ordinances when installing the speaker .
5. Attach the speaker wires to the captive screw connector — A TTENTION: Do not tin the wires. Tinned wires do not r emain tight in the captive screws and can br eak easily after several bends.
• Wiring Multiple Speakers Using Loop-through: A loop-through electrical connection is made on the cr ossover board of the CS 26T . Connect the wires to the captive scr ew connectors of the speakers, as shown in figure 36. Be sur e to tighten the screws.
• The impedance of the speakers downstream of the one being tested can be measured while the system is on by connecting to the outer (LOOP) terminals of the captive screw connector , as shown in figure 38. Impedance T est Points To next speaker(s) Red Wire (+) fr om Amplifier Black Wire (-) fr om Amplifier Amplifier Te st Points Figure 38.
7. Attach the speaker wire to the strain relief tie down point using the pr ovided zip tie. Captive Sc re w Connector Strain Relief Ta b (zip tie) Figure 40. Attaching the Speaker Wir e to the Strain Relief Point 8. Mount the CS 26T (see figure 41). a.
9. Set the rotary tap selector switch — Use a small screwdriver to set the tap selector switch to the appropriate setting. A TTENTION: When setting the taps for a distributed (high impedance) system, do not tap the system above the rated power of the amplifier .
Installing the CS 120P in a Har d Ceiling If you are installing the CS 1226T in a har d ceiling (having no ceiling tiles), with the ceiling structure in place, install the CS 120P: • It is the responsibility of the installer to identify a suitable mounting location and pr ovide the mounting hardwar e.
