CSP-SERIES

Thank you for choosing Senal.

The CSP-series speakers are passive coaxial two-way speakers that provide premium sound quality for use with 70V or 100V systems and for low-ohm systems.

These high power - low distortion speakers feature wide coverage that evenly distributes high fidelity audio to fill large and small spaces. All models are ideal for broadcasting announcements and music reproduction in commercial and residential applications.

The CSP-series ceiling speakers have a multi-tap transformer, which allows flexibility in configuring multiple speakers of a high-impedance system. It is easily accessed with the multi-tap selector on the front baffle of the speaker. Low frequencies are enhanced with a vented port, and precise and smooth high frequencies are delivered by the coaxially mounted 3/4" titanium-coated tweeter. The sealed backcan enhances overall fidelity by focusing the sound and preventing the distribution of sound into the surrounding ceiling structure.

Removable locking connectors simplify the process of wiring the speakers. Each speaker comes with the mounting brackets and hardware necessary for installation. The attachment screw system makes installation simple while providing a secure mounting connection to most ceiling types. Secondary support tabs ensure extra security for compliance with building codes. The speakers can be painted to match ceiling décor.

Setting Up

The CSP-series speakers are designed for easy installation. If necessary, installation can be accomplished without access above the ceiling.

Tools needed for installation

Drywall saw
- Slotted screwdriver
- Phillips head screwdriver
- Wire stripper
- Pencil

Preparing the ceiling

Drop Ceilings

1. Locate the ceiling tile in which the speaker is to be mounted and remove the tile from the ceiling.
2. Measure to find the center of the tile and place a mark there. Use that mark to center the cutout template on the tile. With a pencil, trace an outline of the cutout template on the tile.
3. Use a drywall saw to cut along the traced line.

Pro tip: For easy cleanup it's best to perform this step while placing the tile over an open box or trashcan.

1. Replace the ceiling tile into the ceiling.
2. Insert the rails through the hole.
3. Place the rails on either side of the hole so that the inverted "V" ends of the rails fit over the ceiling grid rails. The flat side of the rails should rest on the tile, and the side with the pre-cut holes should stand perpendicular on either edge of the hole.

Note: The rails of the mounting bracket do not attach to the ceiling grid rails, but suspend over them.

1. Insert the C-ring by angling it through the hole using the open end of the ring.

Fixed Ceilings

1. Locate the spot where the speaker will be installed
2. Use a stud finder to locate studs in the ceiling. Make sure they won't interfere with your installation. If a stud is near the location of your hole, make sure that there is 1-inch clearance between the edge of the hole and the stud.

Pro tip: Drill a small pilot hole and probe inside the ceiling with a stiff wire to make sure there are no obstructions where you are planning on placing the speaker.

1. With a pencil, trace an outline of the cutout template on the ceiling.
2. Use a drywall saw to cut along the traced line and remove the cutout from the ceiling.
3. Pull the speaker wire out so that it extends beyond the ceiling and gives you enough length to complete the installation.

Connecting the wiring to the removable locking connector

CSP-162

1. Open the connector cover plate door.
2. Remove the locking connector from the socket
3. Strip approximately 1/4" (6 mm) off the ends of the insulation on the speaker wires.
4. Insert the exposed ends of the wires into the connector and tighten the screw-down terminals using a small flat blade screwdriver.

Wiring Schemes

The removable locking connector has four terminals. The pin function of each terminal is listed on the label located on the speaker.

Pins 2 and 3 are the "+" and "-" inputs of the speaker, and they are looped inside the speaker to pins 1 and 4 (Pin 1 connects to Pin 2, and Pin 3 connects to Pin 4.) Pins 1 and 4 are designed as loop-through connections to successive speakers.

Parallel wiring

The advantage of this wiring scheme is that when the connector is pulled out of an individual speaker, the following speakers will remain connected. This wiring scheme is useful when troubleshooting because you can disconnect one speaker at a time from the system without disabling successive speakers. In this scheme pins 1 and 4 have no wires in them.

    A["FROM AMPLIFIER OR +"] --> B["PREVIOUS SPEAKER"]
    C["1234"] --> D["+ TO NEXT"]
    E[" "] --> F[" Speaker"]

1. Insert both "+" wires into pin 2 (one wire from the amplifier or the previous speaker; the other wire to the positive terminal of the next speaker.)
2. Insert both “-” wires into pin 3 (one wire from the amplifier or previous speaker; the other wire to the negative terminal of the next speaker.)
3. Make sure both screw-down terminals are securely tightened.

Note: Because there are two wires connecting to each terminal, it is important to make sure that the proper contact has been made and that both wires are securely connected with the screw-down terminal.

1. Tighten the empty screw-down terminals of pins 1 and 4 to avoid unwanted vibration.

Loop-through wiring

In this scheme, the subsequent speakers are connected via pins 1 "+" & 4 "-" . When one speaker is disconnected, all successive speakers are disconnected too. This scheme can be advantageous when using larger gauge wiring, and when required by local building code. An entire section of speakers can be isolated while not affecting the wiring.

1. Insert the "+" and "-" wires from the amplifier or previous speaker into the 2 "+" and 3 "-" pins respectively.
2. Insert wires into pin 1 "+" and pin 4 "-" and connect them to the next speaker's pin 2 "+" and pin 3 "-" respectively.
3. Make sure all screw-down terminals are securely tightened.

Attaching and securing the wiring to the speaker

CSP-162

1. Using a slotted screwdriver, remove the horizontal screw of the strain-relief fitting closest to the cover plate door.
2. Loosen the hold-down screws of the sliding pieces of the strain-relief fitting with a Phillips head screwdriver.
3. Run the wires through the opening of the fitting and plug the removable locking connector into the connector socket in the speaker.

Warning: DO NOT FORCE THE CONNECTOR INTO THE SOCKET.

1. Replace the horizontal screw that was removed.
2. Tighten the strain relief fitting by gradually tightening both of the horizontal screws.
3. Once the speaker cable is securely clamped into place, tighten the two hold-down screws.

Caution: If using plenum cable, do not over tighten the strain relief fitting. It can strip the cable and cause damage.

1. Once the wires have been installed and are securely clamped, close the cover plate door and secure it by tightening the screw with a Phillips head screwdriver.

Caution: DO NOT OVER TIGHTEN. Over tightening can weaken or damage the ceiling tile or ceiling structure and damage the mounting tabs.

Adjust the Multi-Tap Selector

Before attaching the grille, set the multi-tap selector dial to the appropriate setting. Delay attaching the grilles until the taps for all speakers in the system are adjusted.

The multiple taps of the CSP series allow the flexibility of determining how much power each speaker drives. For low-ohm systems, set the dial to the "16R" position.

Caution: ⚠️ DO NOT CONNECT THE SPEAKER TO A HIGH-VOLTAGE SYSTEM WHEN THE TAP IS SET ON BYPASS 16 OHMS (16R SETTING ON THE TAP SELECTOR). DOING SO WILL DAMAGE THE SPEAKER.

Attaching the Grille

1. Place the grille over the speaker baffle.
2. Press the edge of the grille into place until it is level with the rim.

Note: Pressing on the center can dent the grille.

Caution: Make sure the grill is firmly seated into the speaker to prevent it from vibrating or falling.

Painting

Preparing

Remove the grille by inserting the included grille removal key in any hole at the edge of the grille and pull out to lift the grille. Clean off any oily residue by rubbing the surfaces with a cloth dampened with a mild solvent (like mineral spirits) and wait until dry. Do not use a wire brush, sandpaper, harsh detergents, chemicals, or strong solvents to prepare these surfaces. It can cause permanent damage to the grille and rim.

Painting the rim

Apply at least two coats of either latex or oil-based paint to the rim. For best results apply a coat of oil-based primer first.

Painting the grille

Spray on at least two thin coats of latex or oil-based paint. Applying the paint to the grille with a brush or roller is not advised because it can create clogs in the mesh and diminish the sound quality of the speaker. After the paint has dried, replace the grille.

Caution: When painting the speaker after it is installed, make sure to cover the speaker baffle. Do not attempt to paint the interior of the speaker. It could cause permanent damage.
