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-2352SC is a 2-way, flush-mounted ceiling speaker that offers a wide frequency range and high-quality sound output. Use of optional mounting hardware permits versatile mounting to match a wide range of applications and installation locations. 3. FEATURES • A rear-open type 2-way speaker system employing a speaker element designed to provide a wide frequency range.
5. INSTALLATION A dust cover is pre-mounted on the rear of the speaker at the factory. Pay attention not to accidentally take it off during speaker installation. The F-2352SC ceiling speaker can be mounted in 6 different configurations: • Direct mounting to a strong ceiling panel No additional hardware required. • Direct mounting to a weak ceiling panel Use the optional HY-RR2 Reinforcement Ring. • Mounting to a ceiling frame Use the optional HY-RR2 in conjunction with the optional HY-TB1 Tile Bar Bridge.
2-2. Mounting to a ceiling frame Use the optional HY-RR2 Reinforcement Ring in conjunction with the optional HY-TB1 Tile Bar Bridge. Note Refer to the instruction manual included with the HY-TB1 for the correct ceiling mounting procedure. [Installed HY-TB1 and HY-RR2] Ceiling frame HY-TB1 (optional) HY-RR2 (optional) Ceiling panel 2-3. Ceiling mounting in a larger than specified hole Use the optional HY-RR2 Reinforcement Ring in conjunction with the optional HY-TR1 Trim Ring.
2-5. Hanging from a ceiling suspension pipe (exposed installation) Use the optional HY-BC1 Back Can. [Installed HY-BC1] Note Refer to the instruction manual included with the HY-BC1 for Back Can installation. (Example of mounting to suspension pipe) Suspension pipe Caution Ensure that this length is shorter than 53 mm (2 3/32"). Speaker cable HY-BC1 (optional) Step 3. Connect the speaker cable to the push-in terminal. Tip Use the 600 V vinyl-insulated cable (IV or HIV wire).
4-1. Flush ceiling mounting (in the cases except for Step 2-5) Insert the speaker through the mounting hole till it contacts the ceiling panel. While doing so, avoid directly touching the speaker's diaphragm and diffuser section. Mounting hole WARNING Never grab the diffuser section as a hand hold. The speaker could fall due to damage, resulting in possible personal injury.
Step 5. Set the input power. Turn the input selector switch (on the unit's front) to set it to the desired input impedance using a slotted screwdriver. Note: The switch is factory-preset to 1.7 kΩ. Important Never set this switch to low impedance (8 Ω or 16 Ω) when using a high impedance 25, 70, or 100 V line. Failure to follow this instruction could result in damage to the speaker or amplifier. Input selector switch Speaker's front Slotted screwdriver Step 6. Attach the front grille.
6. REMOVING THE SPEAKER FOR MAINTENANCE 6.1. 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. 6.2.
7. REPAINTING THE SPEAKER Follow the procedure below when repainting the front grille: 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. • Use appropriate spray paints for the front grille (grille and frame) materials.
