1. SAFETY PRECAUTIONS • Be sure to read the instructions in this section carefully before use. • Make sure to observe the instructions in this manual as the conventions of safety symbols and messages regarded as very important precautions are included. • We also recommend you keep this instruction manual handy for future reference.
2. GENERAL DESCRIPTION The F-2322CU2 and F-2352CU2 are flush-mounted Ceiling Speaker Systems that offer wide frequency range of high-quality sound output. The F-2322CU2 employs a full-range speaker element, while the F-2352CU2 features a 2-way speaker configuration. Both speaker systems are designed to be mounted to a drop ceiling with use of the supplied tile bridge. 3. FEATURES • Bass-reflex speaker system designed to provide a wide frequency range and high power handling capability.
4. NOMENCLATURE AND DIMENSIONS • F-2322CU2 Unit: mm (inches) [Side] [Front] [Rear] ø230 (9 1/16) ø195 (7 43/64) Safety wire hook 12 (15/32) Front grille (accessory) Mounting hole: ø200 (7 7/8) Connector cover Choke bracket 209 (8 15/64) Safety wire (accessory) Length: Approx. 600 (23 5/8") Tile bridge (accessory) Max. 202 (7 61/64) Max.
5. MOUNTING HARDWARE INSTALLATION Before mounting the speaker, check the ceiling structure is of drop ceiling with 2-foot standard ceiling tiles. [Installation view on Drop Ceilings] Caution Set the tile bridge so that both ends fit securely into the T-grids, even if the ceiling tile accidentally falls off. Tile bridge (accessory) T-grid Ceiling tile [Installation procedures] Step 1. Cut a ø200 mm (7 7/8") hole in the ceiling. Use the supplied paper pattern to position and trace the hole.
Step 3. Attach a safety wire to prevent the speaker from accidentally falling. To attach, tie one end of the supplied safety wire around the speaker's safety wire hook, and tie its snap ring around a secure C-channel bar or suspension pipe.
6. WIRING 6.1. Wiring through Hard or Flexible Conduit Note The choke bracket equipped with the speaker has not been evaluated by UL, for conduit connection and UL514B Standard. Flexible conduit of 3/8 or 1/2 inch trade size and the UL514B conduit fitting of the same trade size can also be used. When using the UL514 listed conduit fitting, detach the equipped choke bracket and mount the conduit fitting instead. Loosen the screw to allow the speaker cable to pass through.
6.2. Wiring with Naked Cables Loosen the screw to allow the speaker cable to pass through. Choke bracket Retighten the screw to fix the speaker cable. Plug the wired input connector into the speaker's socket, then pull the speaker cable from the choke bracket. (For wiring the input connector, refer to p. 10.) Note Ensure that the speaker cable is securely fixed.
7. CABLE CONNECTION TO INPUT CONNECTOR Recommended cable types • Solid copper wire: ø1.0 – ø1.6 mm (equivalent to AWG 18 – 14) • Stranded copper wire: 0.75 – 2.5 mm2 (equivalent to AWG 18 – 14) Cover mounting screw Step 1. Loosen the 2 cover mounting screws, and rotate the connector cover in the direction indicated by the arrow in the figure at right. Speaker unit Connector cover Removable input connector Step 2.
8. SPEAKER INSTALLATION Caution Before mounting, check to be sure that the speaker's 3 mounting tabs are turned inside the unit as shown in the figure. If turned outward, the speaker cannot be inserted through the mounting hole. In Out Mounting tab Step 1. Insert the speaker through the mounting hole till it contacts the ceiling panel. While doing so, avoid directly touching the speaker's diffuser section.
Step 3. Set the input power. Turn the input selector switch (on the unit's front) to set it to the desired input impedance. (Factory-preset to 170 Ω.) Step 4. Attach the front grille. Align the tabs (3 places) on the back side of the grille with the corresponding notches in the unit, then rotate the grille to full stop in the direction indicated by the "LOCK" arrow.
9. REMOVING THE SPEAKER FOR MAINTENANCE 9.1. Detaching the Front Grille 1 Turn the front grille counterclockwise to full stop, then lightly pull it downward. Tip The front grille employs a double-locking system. If the grille cannot be detached when lightly pulled downward, it likely has not yet been fully rotated back to the detachment position. In such cases, take care to rotate the grill fully counterclockwise in order to release the lock. Unlock Front grille 2 Pull lightly. 9.2.
10. REPAINTING THE SPEAKER FRONT GRILLE Note: Be sure to detach the front grille from the speaker before repainting. Step 1. Clean the front grille before painting. Wipe with a soft cloth dampened in a detergent. Caution Do not use thinner or other volatile liquids to clean the grille. Step 2. Spray on a uniform, thin coat of paint. Cautions • Avoid painting with a roller or brush, as the grille mesh holes could become clogged with paint.
12. SAFETY AGENCY COMPLIANCE Both the F-2322CU2 and F-2352CU2 are designed for indoor use only. • General signaling speaker, UL1480 Category UEAY and CAN/CSA C22.5 No.
