PRODUCT FEATURE IDENTIFICATION OWI INC.
INSTALLATION AND WIRING The OWI ICM8 speaker installation system has been designed so that the entire installation can be done from beneath the ceiling. In some cases, with a suspended grid ceiling, it may be easier to access from both the top and bottom of the ceiling tile during the installation process. Typical installation hardware needed for either suspended ceilings or sheetrock ceilings is included.
INSTALLATION AND WIRING Tile Rails: The tile rails are designed to fit either standard 24-inch wide tiles or 600mm wide tiles. The tile rail pieces do NOT physically attach to the T-grid struts. Instead, the inverted-V shape at the ends of the rails sit OVER the T-grid strut. Normally, the rails are supported by the edge of the ceiling tile.
INSTALLATION AND WIRING Step 3 – Expose the input-terminal on the rear of the speaker Remove the rear cover plate, complete with wire strain relief, by loosing the two screws holding it in place, and sliding the plate off. Once the cover is removed, open the strain relief fitting by loosening the horizontal screws. Run the speaker wires through the strain relief opening.
INSTALLATION AND WIRING Using an Alternate Fitting – the existing strain relief fitting accommodates many common fitting requirements. Sometimes, alternate fittings are required, such as for larger diameter conduit or to meet specific code requirements. In these cases, the existing fitting can be easily replaced with a number of available off-the-shelf fittings. Simply remove the existing fitting by unscrewing the two hold-down screws, exposing a 7/8 inch (22mm) knockout hole.
INSTALLATION AND WIRING Guide to the Pins for Connection The removable locking input connector contains 4 terminals. These are numbered on the connector. The label located on the terminal cover plate lists the pin functions. Figure 8 -Connector pins Pins 2 & 3 are the "+" and "-" inputs to the speaker. Pins 2 & 3 are connected to pins 1 & 4 respectively (i.e. Pin 1 connects to Pin 2 and Pin 3 connects to Pin 4) inside the speaker. Pins 1 & 4 are intended as loop-through connections to other loudspeakers.
INSTALLATION AND WIRING Daisy-chain Wiring (Using Loop-Through Terminals - Pins 1 & 4): To daisy-chain the wiring, connect the wire pair of the follow-on speaker to pins 1 and 4. DAISY CHAIN WIRING By connecting the wire pair of the subsequent speaker to pins 1 & 4, then all subsequent speakers will be disconnected when this speaker’s connector is disconnected during troubleshooting.
INSTALLATION AND WIRING Step 6 – Connect a Secondary Support Line A tab is provided on the back of each speaker. This tab allows for connection to an independent and secure anchor point. Some construction codes require using this secondary support point, so please consult the building code in your region. IMPORTANT: OWI ICM8 ceiling speakers can generate substantial vibration. It is HIGHLY RECOMMENDED to use the tab as a secondary support point in case the ceiling tile or structure breaks.
INSTALLATION AND WIRING Step 8 – Adjust Tap Selector The tap selector switch is located on the front baffle. Adjust the speaker to the appropriate tap setting before inserting the grill. In some installations it is advisable to leave all the grills OFF until final adjustment of the taps have been made for the entire system. OWI INC.
Step 9 – Sub Switch The sub switch is located on the front baffle. There are three selections, Full Range, High Ceiling or sub depending on the listener’s preference. In some installations it is advisable to leave all the grills OFF until final adjustment of the taps have been made for the entire system. Step 10 – Insert the Grill Press the grill into place until the front of the grill is flush with the rim. Make sure grill is securely seated to prevent it from vibrating loose and falling.
PAINTING THE SPEAKER The ICM8 speaker's textured white finish does not need further finishing. Where the interior design requires it, these speakers are easy to paint. The speaker backcan and front face are all metal, and the white powdered coat paint can easily be painted over with almost any type of latex or oil based paint. The rim can be painted before installation or after it has been mounted to the ceiling. Painting Process Make sure the speaker is clean and free from any dirt or grease.
TROUBLESHOOTING Problem No output Possible Causes Amplifier Action Make sure the amplifier channel is being fed an input signal (preferably via a “signal input” indicator on the amp). Check that the amplifier channel’s volume is turned up. Connect the speaker and cable, which had no output to another amplifier channel, making sure an input signal is fed to the new amp channel. If you then get output, the problem was the amplifier channel. If not, then the problem may be in the cable or speaker.
