Wiring and Connections

Cable Type

The Delta Controller is cabled using standard 4-conductor speaker cable originating at the Delta control unit passing through the keypad and terminating at the speaker location. Matrix Audio Designs generally recommends using a bundled 4 conductor 16 gauge stranded copper wire in a single continuous run. The keypads also function with Cat 5 or basically any 2 conductor wire configuration that is not used for other devices.

RF Interference

Shielded cable is generally not required for audio installations. Although the Delta Controller does generate very low radio frequency emissions, it uses a digital signaling path during command entry. There are normally no ongoing data communications in the circuit path. Communications only occur at the time a command is issued from a zone. However many other systems do use microprocessor systems where the cabling may be in close proximity such as telephone and security systems, and it is possible for different systems to interfere with each other. If you face an installation where your cable runs are in parallel to these types of systems you may consider shielded cable to the keypads. In this case ground the drain wire by connecting it to the chassis of the Delta Controller.

Distribution Wiring

In general, wiring is installed in a single continuous run between the Delta Controller, the keypad and the speaker location. Other cable routing options such as a home run to a common wiring distribution point, integration with home automation systems, or split zone applications can be significantly different than the general information presented here. These applications are left to the installer’s discretion and experience, which is why Matrix Audio recommends installation by a professional. Examples of common wiring options can be found in the “Controller Connections” section of this manual.

Considerations for New Construction Installations

It’s generally accepted to run the 2 and 4 conductor speaker cables inside walls, in the attic and between the joists in the basement or crawl space. When installing cables within walls, drill the holes in the middle of the studs to avoid having them damaged by screws or nails that could penetrate the cable. Use metal nail guard plates where necessary to protect the cable from future construction damage or from something like nails/screws that are installed to hang future pictures or shelving. When running cables in the attic or crawl space, run them in such a way that they will be out of harm, where they will not be stepped on, snagged, punctured, or could pose a safety hazard.

Do not run cable thru the return air path that utilizes the wall or ceiling space as the plenum.

Securing the Cables

We recommend using electrical cable straps to keep the installation neat and secure. We do not recommend stapling the cables as a single misplaced staple can cause a short that causes trouble during operations and set-up. Do not leave the wires lying in the dirt under the crawl space.

Neatness counts in a professional installation.

Keypad “Rough In” Locations

The keypad device itself will fit in a standard electrical box or new construction plate and you should install 1 or 2 gang (as required) standard electrical boxes to accommodate them before the drywall has been put into place. Keep in mind that because these are low voltage applications, plastic electrical boxes are generally adequate for the keypad, but check local building code requirements to be sure. The high voltage electricians on the job site will know which electrical box is appropriate and within code.These emissions have been accommodated for in design and conform to RF emission standards.
